The spider, Nigma conducens (Cambridge, 1876) was locality recorded in El-Gharbia Governoraye, Egypt. It was collected from cotton plants cultivated in El-Gemmeiza Agricultural Research Station, El- Gharbia Governorate. The biology of the spider, Nigma conducens (Cambridge,1876) was studied under laboratory conditions of 28 °C and 60-65 % RH on nymphs and adult stages of the cotton jassid, Empoasca lybica (De Berg.).Males pass through five spiderling instars, while females pass through six spiderling instars before reaching adult stage. The mean of female preoviposition, oviposition and post-oviposition periods were 15.8, 19.5 and 44.5 days, respectively. The female laid 3-6 egg sacs. The mean number of egg/sac was 12-19 eggs. The incubation period of eggs was 11.7 days. The life cycle of this spider was 59.2 days for male and 62.6 for female. Adult longevity, life span, fecundity of female and food consumption were also studied.

The present investigation was conducted at Rice Research and Training Center (RRTC), Sakha, Kafr El-Sheikh, and Laboratory of Genetics Department, Faculty of Agriculture, Tanta University, Egypt. during the three successive rice growing seasons; 2012, 2013 and 2014. Two rice varieties;SK103 and Rikuto Norin 22 as a parents of the running study and their F3, F4and F5 were evaluated against the Echinochloa crus -galli ( barnyard grass)under natural festation. The results showed that, these varieties showed biologically active suppression ofE.crus-galli under field conditions were values ranged from 2.33 to 12.6 cm for radial area and from 41.33 to 87% of weed control. The selected genotypes are important and suitable for direct seeded rice, also it could be utilized in the breeding programs to
transfer allelopathic activity for commercial varieties to suppress weeds and lowering pollution. The genetic coefficient of variability refers to genotypiceffect which played an important role in the inheritance of all studied traitswere the heritability in broad sense ranged from 98.06 to 99.98 for allelopathic activity. Two of the ten tested SSR markers (Table 1); RM439 and RM164showed polymorphic DNA pattern were the primer RM164 exhibited the bandwith molecular weight 296bp in all genotypes had strong to allelopathic activity and it was absent in poor rice variety. The SSR markers would be helpful and may identify important of DNA sequencing that help in breeding program.

KEEPING THE QUALITY AND EXTENDING SHELF-LIFE OF STRAWBERRIES FRUIT BY USING ARBIC GUM AS EDIBLE COATING
text
article
2016
eng
Coating of strawberries fruit with Arabic gum has been found to enhance their shelf-life and postharvest quality. Arabic gum in aqueous solutions of 5,10, 15 and 20% were applied as a novel edible coating to gardener-mature strawberries which were stored at 20◦C and 80–90% Relative humidity (RH) for 10 days. Fruit coated with 10% Arabic gum showed a significant (P≤0.05) delay in changes of weight, firmness, titratable acidity, soluble solids concentration, ascorbic acid content, decay percentage and color development compared to uncoated fruit control. Sensory evaluation proved the efficacy of 10% Arabic gum coating by maintaining the overall quality of strawberries fruit during the storage period. The results suggest that by using 10% Arabic gum as an edible coating, the ripening process can be delayed
and the storage life of strawberries stored at 20◦C and at the breaker stage can be extended up to 10 days without any spoilage and off-flavor.

POST-HARVEST STUDIES ON REDUCING LOSSES AND MAINTAINING QUALITY OF PACKAGING ROSELLE CALYXES
text
article
2016
eng
The post-harvest technologies of roselle must be developed to maintaining quality. There are no appropriate structures for the shelling ,drying, packaging and storage for the calyxes of Hibbiscus sabdariffa L and it appears that these operations are performed under unsuitable conditions leading to the deterioration of the quality of the Hibbiscus sabdariffa , Lcalyxes .For this, the effect of shelling methods ( hand and tools) ,drying processing (sun and oven drying), packaging materials and storage period on some quality of two cultivars of roselle calyxes extracts was studied. Dark and light roselle calyxes removed the seed’s capsules for obtained fresh roselle calyxes one shelling hand and the other tool shelling, and the after that drying is carried out after shelling by two ways first is sun drying and second way is
an oven air dryer at 55Co for 36 hours to obtain 11% moisture content of dried roselle calyxes. All previously treatment of dark and light red roselle calyxes were divided into two groups randomly assigned to each of the treatment
combinations one were packed in polypropylene (pp) package and the other packed in glass bottles as three hundred gram of each sample and stored for eight months at room temperature. Cultivars of roselle calyxes extracts, the
packaging materials and storage period were highly significant effect for TSS, total acidity and pH but there are no significant different in anthocyanin with drying processing The two, three and four-way interactions were highly
significant for TSS, total acidity and anthocyanin. Total soluble solids content was found to be increased by increasing storage period for both dark and light red roselle cultivars dried by (sun and oven) and packed in (polypropylene and glass bottles). Higher total soluble solids content was recorded for dark cultivar dried by oven packed in glass bottles after 8 months of storage. PH value for dark and light red roselle calyxes decreased with the increase in storage period for the two cultivar with two packaging material and two drying methods from zero days to the end of storage (after 8 months). The pH values of dark roselle extracts was higher than that of light red roselle extracts with all treatments. Dark and light red Roselle calyxes packaged in polypropylene showed pH values largest compared with packaged in glass bottles. The pH
values of dark and light red roselle calyxes extracts dried by sun was less than that dried by oven for two packaging materials after 8 months of storage. Anthocyanin value decreased in roselle calyxes extracts of both dark and light
cultivars with increasing storage period with all treatments. Anthocyanin value for dark cultivar was higher than the light cultivar. Dark and light roselle calyxes extracts packaged in polypropylene had anthocyanin value higher than that packaged in glass bottles during storage periods. Total acidity of dark and light roselle calyxes extracts increased with increasing storage period for all treatments. The dark roselle calyxes recorded the higher titratable acidity than light red roselle calyxes for all treatments during storage period. Titratable acidity of dark and light red roselle was highly with roselle calyxes dried by oven for two packaging materials throughout storage. Roselle calyxes packed in (pp) gave the lowest value titratable acidity as compared with roselle calyxes extracts packed in glass bottles for two cultivars.

2016
eng
This study was done to investigate the toxic effects of aflatoxin B1(AFB1) on Nile tilapia(Oreochromis niloticus) fingerlings and detoxifying these drastic effects by using some antimycotoxins. Therefore, 0.5 and 1g of each
Black pepper, Filofeed plus and Cap T 2 were added to an aflatoxin diet (150ppb) for fingerlings. These diets were offered 6 days a week at 3% daily of actual biomass in glass aquaria (three aquaria / treatment) in the wet Lab.
The experiment lasted for 14 weeks (98 days). The Aflatoxic diet had adversely affected growth performance, survival rate, feed and protein utilization, muscular and abdominal areas and carcass composition of fish as well as residues of AFB1 (ppb) was observed in the viscera and muscles of fish. The addition of antitoxins alleviated aflatoxicosis of fish, moreover, it improved all the above tested parameters. Generally, the results obtained of this study recommended that adding 0.5 or 1g of Black pepper, Filofeed plus and Cap T2 as fish feed additives could be used as detoxifying agents for aflatoxin.

text
article
2016
eng
The aim of this study was to assay supplementation of cysteine into the traditional egg yolk extender for cryopreservation of buck spermatozoa. Semen ejaculates were collected from three fertile baladie bucks, aged 2.0 - 3years using artificial vagina. Collected semen was divided into four aliquots; the first was diluted with Tris-egg yolk extender without any supplementation (control), while the others were diluted with Tris-egg yolk extender supplemented with cysteine at levels of 0.5, 2.5 and 5mM. Semen diluted at a rate of 1:4 and placed into a refrigerator at 5oC for 4 h to equilibrate. At the
end of equilibration period, extended semen was packaged in 0.25ml French straws and stored at –196oC. Thereafter, frozen semen was thawed by dipping the straws into a water bath at 37oC for 30 seconds. Percentages of
progressive motility, live sperm, sperm abnormalities, plasma membrane and acrosome integrity were evaluated post dilution, equilibration period and postthawing of goat semen. The results revealed that there were a significant differences (P<0.05)of the percentages of sperm motility, live spermatozoa, sperm abnormalities and plasma membrane and acrosome integrity among post-dilution, post equilibration and post thawing of buck semen. Treatment supplemented with
2.5mM of cysteine led to significantly (P<0.05) improve the percentages of progressive motility, live spermatozoa, sperm abnormalities and plasma membrane and acrosome integrity of buck spermatozoa during different stages of cryopreservation compared to control and other levels of cysteine addition. In conclusion, supplementation of based Tris-egg yolk extender with 2.5mM of cysteine improves the percentages of progressive motility, live spermatozoa, sperm abnormalities and plasma membrane and acrosome integrity of frozen–thawed buck spermatozoa.

Efficacy Of Using SOYBEAN MILK-BASED SEMEN EXTENDER For FREEZABILITY OF BUCK SPERMATOZOA
text
article
2016
eng
The aim of this study was to investigate incorporating whole soybean milk instead of the traditional egg yolk in goat semen extender. The semen ejaculates were collected from three fertile bucks, aged 2.0 - 3 years using artificial vagina. Collected semen was divided into 6 parts; the first was diluted with Tris-egg yolk extender (TEY) saved as control, while the others were diluted with Tris- soybean milk extender (TSM) at levels of 5, 10, 15, 20and 25%. Pooled ejaculates were further processed for freezing using 0.25ml French straws. Diluted semen at a rate of 1:4 was placed into a refrigerator at
50C for 4 h as equilibration period. At the end of equilibration period, extended semen was packaged in straws and stored at –196oC. Then after, frozen semen was thawed by dipping the straws into a water bath at 37oC for 30
seconds. Percentages of sperm motility, live spermatozoa, sperm abnormalities and recovery rate were determined.
The results revealed that there were significant differences (P<0.05) in buck sperm characteristics (percentages of sperm motility, live spermatozoa, sperm abnormalities and plasma membrane and acrosome integrity) among post-dilution, post equilibration and post thawing processes.A addition of 15% of soybean milk led to a significant (P<0.05) improvement
of sperm motility, live spermatozoa, sperm abnormalities and plasma membrane and acrosome integrity of buck spermatozoa during different stages of cryopreservation compared to control, while the lowest values were recorded at a level of 25% soybean milk extender.On the basis of our results, we concluded that soybean milk-based extender
at the rate of 15% of soybean milk has the potential to maintain buck sperm quality after freezing –thawing process compared with cryopreservation in a traditional protection extender (egg yolk) .

eng
The experiments were carried out at Sakha Agriculture Research Station, Cotton Research Institute, Agriculture Research Center, Egypt. The aim of this investigation was to study heterosis and combining ability for the most important characters of cotton (seed cotton yield, lint yield, boll weight, seed index, lint percentage, lint index and hallo length). Ten cotton genotypes TNB, Karsheneski 2, G.45, G.89 x G.86, G.86, G.94, G. 93, CB.58, G.75 x Sea and Australian
12 were crossed in half diallel. These parents and their respective 45 F1 crosses were evaluated in a randomized complete blocks design. The results obtained could be summarized as follows:-Highly significant mean square values were obtained for genotypes, general combining ability and specific combining ability for all the studied
characters. The best general combiner for all studied traits were parents G.94 and G.75 x sea. Also the best combination for most of studied characters were crosses G.45 x CB 58, TNB x Aus.12, Kar.2 x G.94, G45 x CB 58, G.94 x(G.75 x sea) and G.93 x (G.75 x sea). The first three principle components were significant and accounted
about 90.3% of the total variability of all characters. Which having maximum Eigen value. Lint index followed by lint percentage, boll weight and lint yield were a primary source of variation in the first ax. The second ax was principally affected by seed cotton yield and hallo length. The ten parents in this study were grouped in different clusters and there were accordance between parental diversity and significant general and specific combining ability.

COMBINING ABILITY ESTIMATES FOR SOME AGRONOMIC,YIELD COMPONENTS AND BLAST REACTION TRAITS IN RICE (ORYZA SATIVA L.)
text
article
2016
eng
Combining ability analysis was carried out in rice, through A 6 x 6 diallel set analysis (excluding reciprocals) for some agronomic and yield components traits as well as blast reaction at the Experimental Farm of Sakha Agricultural Research station, Sakha, Kafr El-Sheikh, Egypt during 2015 and 2016 summer seasons. The ratio of variances due to general and specific combining abilities (ó2 GCA / ó2 SCA) was found to be lower than unity for all studied characters, except 1000-grain weight, suggesting greater importance of non- additive genetic variance (over dominance or epitasis) in the
inheritance of these characters. Obviously, highly significant and positive estimates of (GCA) effects were recorded for chlorophyll content in Large stigma rice variety, indicating that this entry could be used to improve such trait. Regarding to blast reaction, the rice varieties; Giza 177, Giza 179 and Giza 178 exhibited significant and highly significant negative values of GCA effects, while Large stigma and Baldo varieties showed the positive values of GCA effects. The results proved that the rice variety Large stigma considered as good combiner for improving the earliness, shortness and high chlorophyll content. Also, estimates of GCA effects showed that the parents, Giza 177, Giza 178 and Giza 179 were found to be good general combiners for blast reaction. Moreover, Giza 178 and Giza 179 were the best general combiners
for grain yield/plant.
In addition, Blast reaction showed that five crosses were found to be high or highly significant and negative estimates of SCA, their estimated values were ranging from -0.70 for Giza 177 x Large stigma to -0.83 for Giza 178 x Large stigma. The crosses which gave negative significant values could be utilized in rice breeding program to improve this trait. Moreover, 5 crosses out of 15 combinations possessed significant desirable SCA effects for grain yield / plant involving two kinds of combinations between the parents of high x high GCA effects, such as SKC23819-192 x Baldo, suggesting that additive x additive type of gene action play an important role in the inheritance of thistrait.

The main objective of this work was to compare between the selection methods of maintaining and renewing the breeder seeds of Giza 92 followed by the Department of Cotton Maintenance, Cotton Research Institute, A.R.C.,
and selection index procedures for the possibility of selection higher yielding plants with the same fiber properties of Giza 92. To form the new nucleolus (breeder seeds) two selection procedures were followed, the first was the procedure followed by the Department of Cotton Maintenance based on selection the best families representing the type of Giza 92 variety. The second was the procedure of classical selection index with different applications of selection intensity. Yield and yield components as well as fiber traits were evaluated for seven nucleolus, one from the traditional method and
six from selection index method. Mean results showed that the means of the selected families were slightly differ from comparisons, which indicate the homogeneity between these families, also values of SE and C.V. % were relatively low for all traits except for SCY and LCY confirming the homogeneity between these families and the influence of seed cotton yield (SCY) and lint cotton yield (LCY) by environmental factors. Heritability of the studied traits ranged from moderate 64.56% for yellowness (+b) to high 97.81% for uniformity index (UI %). These results indicate the possibility to
maintain the standard characters of Giza 92 variety by simple selection for these traits. Factor analysis showed that, three classes of independent factors were chosen based on Eigen value > 2, which together compose 61.28% of total variation. Contribution of these three factors in total was 23.83, 19.32 and 18.13%, respectively. Due to the relatively important of traits in each factor, factor 1 considered yield factor, factor 2 considered yield and fiber factor and factor 3 considered fiber factor. Which exhibit the importance to compare the selection index procedure in this work based on yield traits
alone, fiber traits alone and all traits. Genotypic correlation revealed that selection for the direction of yield improvement can simultaneously maintain micronaire value (MV) and yellowness (+b) in the range of the variety standard. On the other hand, genotypic correlation between fiber strength (FS) which characterize G 92, was undesirable (negative) with fiber length at 2.5% Span length (2.5%SL) and elongation (E%.) and positive with micronaire value (MV), this mean special balance must be consider at the selection for these traits. Regarding to predicted gains, Application-3 (using yield and yield components with selected three families) presented the highest desirable

General (GCA) and specific (SCA) combining ability were estimated in a lines x testers crossing program comprising 36 crosses of maize produced by crossing eighteen yellow inbred lines with two testers in 2014 season. The resulting 36 test crosses along with the two check hybrids SC.162 and TWC353 were evaluated for six traits, i.e. days to 50% silking, plant height,ear height, ear length, ear diameter and grain yield/ha at Sakha and Ismailia Agric. Res. Stations in 2015 grown season. Significant differences were obtained among crosses and their partitioning into lines, testers and line x
testers for all studied traits, except testers for ear diameter and line x tester for number of days to 50% silking, plant height, ear length, ear diameter and grain yield. The additive gene action was more important than non-additive
gene action for days to 50% silking and grain yield, while the non-additive gene action was more important for other traits. The best inbred lines for GCA effects were Sk-5001/32 and Sk-5001/33 for days to 50% silking, Sk-5001/36
and Sk-5001/38 for plant and ear height, Sk-5001/21, Sk-5001/29 and Sk-5001/36 for ear length, Sk-5001/24, Sk-5001/29 and Sk-5001/36for ear diameter and Sk-5001/29, Sk-5001/30 and Sk-5001/36 for grain yield. Whereas, the line GZ-666 was the best tester for GCA effects for number of days to 50% silking and plant and ear height, while the single cross 162 was the best tester for ear length, ear diameter and grain yield. Two crosses (Sk-5001/25 x GZ-666 and sk-001/33 x SC 162) were found to be the best for SCA effects for grain yield. Most single crosses and all three way crosses
were significantly outyielding both checks SC162 and TWC353, respectively.

2016
eng
Tow field experiments were carried out at Experimental Farm, Faculty of Agricultural, Omer AL-Mukhtar University, EL-Baida, Libya during 2011/2012 and 2012/2013 seasons to study the effect of biofertilizer treatments in four levels (Control, Phosphorin (P), Cerialin (C), Mixture (P+C)) and three levels of mineral nitrogen fertilizer (80, 100 and 120 kg N/ha) and their interactions on yield and yield components of triticale. A Split plot design in three replications was applied. The obtained results can be summarized as follows: Plant height (in both seasons) and chlorophyll content (in 2011/2012
season), grain no./spike, 1000-grain weight and grain weight/spike (in both seasons) were significantly increased under biofertilizer treatments compared with control treatment. The use of Cerialin mixed with phosphorene gave the
highest values of them compared with other treatments, and also the highest value of spike length, grain and biological yields (t/ha) of triticale (in both seasons) and spike weight (in the first season) was obtained under Cerialin alone or mixed with phosphorene treatment. Increasing nitrogen levels lead to highly significant and significant increase in plant height in the first and second seasons. The highly significant differences were observed with chlorophyll a and chlorophyll b content (mg/ds) of triticale plant in 2011/2012 season. Also, data showed that highly significant differences existed among the nitrogen levels on spike length and weight (in 2011/2012 and 2012/2013 seasons) and significant differences on spike length and spikelets number/spike (in 2011/2012 season), as well as grains number/spike, grain weight/spike, protein content (%) (in 2012/2013 season) and 1000-grain weight, grain and biological yields (t/ha) of triticale (inboth seasons). The level of 120 kg N/ha gave the highest values without significant differences when using 100 kg N/ha for some traits. The interaction effect between biofertilizer and nitrogen levels was significant on spike weight, number of grains/spike and grain weight/spike (in2012/2013 season) and biological yield of triticale (in both seasons). The highest values were recorded when using mixture of phosphorene and Cerialin treatment at the rate of 120 Kg N/ha.

2016
eng
A field experiment was carried out during 2014/2015 and 2015/2016 seasons on Egyptian lime trees (Citrus urantifolia Swingle) at Baltim region, Kafr El-Sheikh governorate, Egypt, to study the effect of humic acid applications on soil properties, growth, yield, fruit quality and leaf nutrient content of Egyptian lime trees. Four treatments 0, 10, 20 and 30 ml/tree soil application were arranged in a randomized complete block design with three replicates.
The obtained results showed that application of Humic acid profoundly alleviated salinity effect by enhancing available nutrients and microbial activity. In addition, to it is induce a significant improvement of tree size and growth in terms of shoot length, leaves number/shoot, leaf area and canopy volume. Moreover, yield as kg/tree or number of fruits per tree was significantly increased with increasing humic acid level in both seasons. Fruit quality as weight (g), volume (cm3), juice% and SSC% were significantly increased by increasing humic acid levels, whereas acidity was slightly
decreased. Soil application of humic acid increased leaf N, P, K, Fe, Mn and Zn contents. The results suggested that humic acid treatment at 20 ml/tree have great potential in alleviating salinity stress on growth and productivity of
Egyptian lime trees under saline soil conditions.

eng
The present study was carried out at the Experimental Farm of Sakha Agriculture Research Station Kafr El-sheikh, Egypt during the growing seasons 2013 and 2014 to study the effect of foliar spray of salicylic and ascorbic acids (vitamin C) on growth, yield and yield components of maize (Zea mays) hybrid SC.128 under irrigation interval treatments. The experimental design was a split-plot with four replicates. The main plots were devoted to irrigation intervals:- 1-irrigation every 15 days (control). 2- irrigation every 20 days (moderate water deficit). 3- irrigation every 25 days (severe water
deficit).While the sub plots were assigned to foliar applications of salicylic acid (SA) and ascorbic acid (AA):
1-sprayed with water (control).
2- sprayed with 100 ppm of salicylic acid (SA).
3- sprayed with 200 ppm of salicylic acid (SA) 4- sprayed with 100 ppm of ascorbic acid(AA). 5- sprayed with 200 ppm of ascorbic acid (AA). 6- sprayed with 100 ppm of salicylic acid(SA). + foliar with 100 ppm of corbic
acid(AA).Following data were recorded :- plant height, leaf area, photosynthetic pigments (chl. a, chl. b and total chl.),ear height, ear weight, ear length, ear
diameter, number of grains ear -1,grains weight ear-1, 100-grains weight and grain yield (ard./fed). All growth parameters were significantly reduced with widening intervals irrigation 25 days while ascorbic acid, particularly at 200 ppm tended to mitigate the adverse effect of water deficit on growth and yield components to maize plants. It is suggested that ascorbic acid could be a promising material used to reduce the harmful effect of water stress on the
growth and yield of maize plants.

study the effect of three intercropping patterns(2 ridge kenaf (k):1 ridge maize (M),( 2k:2M ) and (2K:4M) and three nitrogen levels (75,105 and 165 kgN/fed)on the productivity of maize (Three way Cross.310) and kenaf (Gize 3)
The experiments were laid out in a split- plot design with three replications, three of intercropping patterns were distributed in the main plots, where, nitrogen levels were randomly allocated in the sub-plots. The main obtained
results could be summarized as follows:
1- Obtained results showed that all traits of kenaf were significantly affected by intercropping system of maize with kenaf and nitrogen fertilizer, except plant height, fruting zone length, technical length and green yield/plant as compared with pure stand in both seasons. Intercropping system of 4 M:2K(S3) recorded the highest values for all character, while, the lowest values were obtained from intercropping 1M:2K ( S1).
2- All characters for yield and yield components of maize were significantly affected by intercropping system and nitrogen fertilizer in the two seasons, except plant height in the first season .The highest values (14.11and13.66) were obtained from intercropping kenaf with maize on S3(4M:2K) in both seasons with hight rate of nitrogen fertilizer N3 65kgN/fed.).Whereas lower values (11.14 and12.02 ard./fed) were obtained from intercropping system S1(2kenaf:1maize)with lower rate on nitrogen fertilizer N1(45kgN/fed).
3-The interactions between intercropping system and nitrogen rates of kenaf and maizet had no significant effect on all maize and kenaf characters under study in the both seasons.
4- The highest values of land equivalent ratio (LER) was1.5 in both seasons from intercropping kenaf with maize on S3(4maize:2 kenaf) under the hightest nitrogen rate(165kgN/fed.) 5- The highest gross return was obtained with intercropping system 4M:2K(S3) in both seasons(9250.633 and 9370.92 in the first and second seasons,resp.).
From this study it could be concluded that, the best results were kenaf was obtained by intercropping system of four ridges maize with two ridges kenaf under the highest nitrogen rate of N3(165 kgN/fed.).

The present study was carried out at Itay EL-Baroud Agriculture Research Station, EL-Behaira governorate, Egypt during two agricultural seasons of 2012/13 and 2013/14.Three faba bean cultivars (Nubaria 1, Giza 716 and Sakha 1) were used to study the effects of five commercial growth substances (DotraFirt, Dotra Micro Plus, Dotra Frost, Crop
Plus and the control) on leaf area index (cm2), leaf fresh weight/plant(g), leaf dry weight/plant (g),fresh and dry stem weights/plant (g), total flowers/ plant, percentage of buds shedding/plant. The three faba bean cultivars were sown
in a split plot design with three replications. The results indicate that, significant differences were detected among all
used cultivars, growth substances treatments and their interactions in all studied traits in both seasons, except for the cultivars effect and their interaction on leaf area index in both seasons. The cultivar Nubaria 1expressed the best desirable mean values for total flowers/plant, Total shedding of buds/plant and most vegetative traits in both seasons .While, the
cultivar Giza 716 gave the best desirable mean values for Total flowers/plant in both seasons. The growth substance Crop plus showed the most desirable effect on total flowers/plant and expressed the second good treatment for reducing the percentage of total shedding of buds/plant in both seasons, while the growth substance Dotra micro plus had good desirable effect on total flowers/plant and total shedding of buds/plant in both seasons. The Dotrafirt treatment had undesirable effect on total shedding of buds/plant in both seasons. Farmers in Delta conditions can use the two faba bean cultivars Giza 716 and Nubaria 1 to obtain the highest number of flowers and the lowest percentage of total shedding of buds/plant. The two growth substances Crop plus and Dotra micro plus could be used to obtained for the highest
vegetative growth under Delta conditions.

text
article
2016
eng
Two field experiments were carried out at the Experimental Farm, Faculty of Agriculture, Kafrelsheikh University, Egypt, during 2013/2014 and 2014/2015 seasons to find out the effect of nitrogen fertilizer level and time of foliar spraying with potassium fertilizer on straw, fiber and seed yields and its components of some flax genotypes. The experiment was carried out in a split-split plot design with four replications. The main-plots were assigned to flax genotypes (Sakha 1, Strain 402/1, Sakha 5, Strain 541/G/1, Sakha 3 and Strain 620/3/5). The sub-plots were allocated to nitrogen fertilizer levels (30,45 and 60 kg N/fed). The sub-sub-plots were occupied with times of foliar spraying with potassium (spraying with potassium after 50 DFS, after 70 DFSand after 50 and 70 DFS). The obtained results could be summarized as
follows: Sakha 1 cultivar produced the highest values of 1000-seed weight in both seasons. Meanwhile, Strain 402/1 resulted in the highest values of seed yield g/plant in the second season. However, Sakha 5 produced the
highest values of fruiting zone length, number of capsules/plant, number of seeds/capsule, number of seeds/plant, seed yield / plant (in the first season) and seed yield / feddan in both seasons. While, Sakha 3 cultivar resulted in the highest means of total plant height, technical length, straw yield/plant (in the first season) and straw yield/fed in both seasons. Strain 620/3/5 produced the highest values of straw yield/plant in the second season, fiber yield/plant and fiber yield/fed in both seasons.Maximum means of all studied characters were produced from fertilizing flax plants with 60 kg N/fed., while the lowest values of these characters were obtained from plants that fertilized with 30 kg N/fed.
·Foliar spraying flax plants twice with potassium after 50 and 70 DFSsignificantly exceeded other studied times of foliar spraying with potassium and produced the highest values of all studied characters.
Form the obtained data in this study, it can be concluded that mineral fertilizing Sakha 3 cultivar, Strain 620/3/5 and Sakha 5 with 60 kg N/fed and foliar spraying twice with potassium after 50 and 70 DFS from sowing could be recommended in order to maximizing straw, fiber and seed yields, respectively under the same conditions of this research.

·The maximum values of growth characteristics (No. of leaves/plant, bulb diameter (cm), dry weight of onion plant and leaf area/plant), average bulb weight, culls bulb weight, marketable and total bulbs yield (t fed.
-1) were obtained under foliar application of salicylic acid at the rate of 200 ppm, while the lowest values were recorded under spraying salicylic acid at the rate of 100 ppm.
·Foliar application of onion plants with mixture of Fe, Zn and Mn markedly increased bulb yield and its components with best growth characteristics followed by that sprayed with Zn. Foliar application of salicylic acid at the rate of 200 ppm andmicronutrients (Fe + Zn + Mn, at the rate of 2 ml L
-1 in combination) resultedin the tallest plants, the heaviest bulb weight, culls bulb weight, marketable and total bulbs yield (t fed. -1) and the highest leaf area/plant of onioncompared with control treatment.
·After storing for 180 days the lowest values of weight loss % was observed under combination of salicylic acid at 200 ppm with mixture of Fe, Zn and Mn which achieved the maximum values of remained bulbs% in both
seasons. Moreover, the obtained data revealed that, the highest nutritional values in onion bulb tissues were detected when mixture of the three nutrition elements (Fe, Zn and Mn) together. Generally, from the economic point of view, this study can be recommend that foliar application with salicylic acid for three times with the rate of 200 ppm in each once as well as spraying with a mixture of micronutrients (Fe+Zn+Mn at the rate of 2 ml L-1) to increase onion
productivity and storability as well as quality improvement.

A study was carried out at the Agronomy Department, Faculty of Agriculture, Kafr El-Sheikh University and the Rice Research and Training Center, Field Crop Research Institute, during 2013, 2014 and 2015 seasons to study the inheritance of heat stress tolerance and some traits in rice crosses. The six populations; P1, P2, F1, F2, BC1 and BC2 of each of the three studied crosses were evaluated in the New Valley research field under heat stresses
using randomized complete block design (RCBD) with three replications. The results indicated the presence of non-allelic interaction for all studied traits in all crosses. The gene action of the studied traits indicated that additive,
dominance and epistemic genetic components was important for the expression of the traits studied. The results showed considerable amount of dominance effect for days to 50% heading, plant height, total stigma length,
anther length, 100-grain weight and grain yield/ plant indicating that selection for these traits should be postponed to the later generations until homozygosity is achieved. Also, the relative importance of additive × dominance effects varied within traits and crosses under heat conditions. Among the epistatic components, the dominance × dominance was greater in magnitudes than additive × additive and additive × dominance in most of the studied traits. Positive heterotic effects relative to the mid-parent and betterparent were found for most of the studied traits under both conditions.

eng
This investigation was conducted at Sids Agricultural Research Station, Bani-Swief Governorates, during two seasons of 2012/2013 and 2013/2014, to evaluate the effect of six nitrogen treatments (60 kg N without starter fertilizer, 60 kg N with starter fertilizer, 90 kg N without starter fertilizer,90 kg N with starter fertilizer, 120 kg N without starter fertilizer and 120 kg N with starter fertilizer) and three application methods (broadcasting, side dressing and top dressing) on vegetative growth characters, yield and yield components as well as quality and storability of onion.The obtained results could be summarized as follow:
• The obtained data revealed that plant height, No. of leaves/plant, bulb diameter, bulb length, bulb weight and No. of days to maturity were significantly affected by nitrogen dose in both seasons.
• Adding the highest nitrogen dose of 120 kg N with starter fertilizer gave the highest values of plant height, No. of leaves per plant, bulb diameter, plant weight and No. of days to maturity in both seasons.
• Adding of nitrogen by top dressing method appeared the largest values in respect to all vegetative growth characters, except for bulb diameter in the first season.
• Nitrogen dose significantly affected bulb weight, total yield/fed., marketable yield/fed.and culls yield in both seasons.
• The highest values of bulb weight, total yield and marketable yield were obtained under nitrogen dose of 120 kg N with starter fertilizer in both seasons.
• Application of nitrogen fertilizer by top dressing methods achieved the maximum values of bulb weight, total yield and marketable yield in both seasons.
• Adding of 120 kg N/fed. with starter fertilizer achieved the maximum values of TSS% in both seasons and dry matter % in the second season.
• The largest values of TSS% and dry matter % were obtained by adding nitrogen fertilizer by top dressing method in both seasons.
• After storing for two months the lowest values of weight loss % were observed under nitrogen dose of 60 kg N/fed. without starter fertilizer, in both seasons.
• Application of nitrogen by top dressing appeared the lowest values of weight loss% after storing for 2, 4 and 6 months in both season.
• Based on the current experimental results, with regards to the production as well as economic analysis, application of 120 kg N/fed. with starter fertilizer by top dressing method may be suggested for maximizing onion production
under similar conditions of this work and further investigations are needed to be conducted in other agro ecological zones of Egypt.

The investigation was conducted at laboratory of cereal technology, Agronomy Department, Faculty of Agricultural, Omer AL-Mukhtar University, EL-Badia, Libya during 2015 /2016 autumn season to study the effect of three wheat cultivars (Kufra, Masry1 and Kazeino) and three size of grains i.e. 1000-grain weight ranged from 40.3 to 43.6 g. for large size, 32.14-37.22 medium and 22.14 to 25.33 g. for small size and their interactions on seedling growth characters of wheat. A factorial experimental design in three replications was applied and LSD test were used to mean comperes. The
obtained results can be summarized as follows: Data showed that there were no significant differences among the
wheat cultivars and their effect on germination percentage (%). But there were significant differences among the wheat cultivars on properties of seedlings. Masry1 wheat cultivar surpassed Kufra and Kazeino wheat cultivars in most of
seedling growth characters (which gave the lowest number of days from sowing to completely rise of the first, second and third leaves, root and shoot length, seedling fresh and dry weight and leaf area per seedling. The lowest values were recorded by Kufra wheat cultivar. Results obtained indicated that there was significant effect for seed size
on all the studied traits except of germination percent (%), where large seeds size reported the shortest significant values for day to emergence (first leaf through scabbard, one leaf, two leaves and three leaves emergence), tallest
stem and rootlet, heavy fresh and dry weight seedlings, highest leaf area compared with small seed size.
There was no significant effect for the interactions between seed size and the genotypes on germination percent (%)and germination strong, fresh and dry weight of seedlings stem and rootlet length, while There was significant effect for the interactions on the first and second leaf emergence and leaf area index. Masry1 wheat cultivar with large seeds size surpassed Kufra and Kazeino in the time of leaves emergence and leaf area index.

The main objective of this study was to identify the grounds for divorce and its effects on women and children in some Egyptian villages.A purposive sample of 120 rural women was selected and personally interviewed from three villages in Biella district, Kafr El-sheikh governorate. Aquestionnaire was designed and developed to collect the data of the study.
Frequencies, percentages, and weighted means were the statistical methods for data presentation and analysis.
The results of the study had showed that, the majority of divorced women were married according to their parent's desires. The dominant criterion in the selection of the spouses was his economic status. The most frequent length
of engagement period ranged from one to more than two years. It was found that, divorce had happened in most cases during the first 10 years of marriage, while it could not withstand in some cases more than one year.
After The divorce, majority of the divorced wives turned back to live with their parents. They assured that, divorce could be avoided if the ex-husband offered an independent house away from his family, did not marry another
wife, and to be moderate in his un-justified jealousy about his wife. Great majority of divorced wives did not filled with remorse for their decision of divorce, but on the contrary, large proportion of them assured the
positive effect of the divorce. Freedom from psychological tension, of the continuing quarrels with the husband and his family, and ending husband's beat and abuse were examples. Divorced wives had exposed to and faced
two forms of violence. They were Physical violence through the exposure to husband beating, and psychological violence resulting from verbal abuse.

Variables affecting husband's violence against his wife (HVW) in three Egyptian villages in Sharkia governorate having different level of development, are analyzed in this study. Results showed a high prevalence of HVW in the selected rural areas. 71.9% of wives reported different types of HVW. The main reasons for HVW were: the desire to visit her parents,
husband influenced by friends. The main consequences of HVW on wives were related to health effects, both psychological and physical. Multinomial logistic regression results showed that nine out of fifteen variables significant determinants of HVW in this study. These variables together explained 40.1% of HVW. Four variables were negatively associated with HVW : husband's age at marriage, husband's income, length of cohabitation, and developmental level of village. Five variables were positively associated with HVW: wife's education attainment, husband's education attainment, wife's
income, degree of family income adequate for living, and social level of the neighbors.

Results indicated that the area and the production of squash at the national level has taken a general trend growing morally statistical,while taken in annual decreasing trend in Hadramout governorate,While productivity has taken on a national level and governorate a
statistical significant decreasing trend year. Results of the study also indicated to increase the productivity of squash as a result of the introduction of new technologies combined with the farmers in selected areas of the Gria and Damon to around about 31.659 tons / ha, an increase of about 17.659 tons / ha, equivalent to about 126% for traditional farming, While the introduction of artistic techniques input costs about 712.789 thousand riyals / ha while the counterpart in the
traditional fields about 528.570 thousand riyals / ha, an increase of about 184.219 thousand riyals / ha, equivalent to about 34.8% for traditional farming. The results showed high return per hectare squash in modern agriculture by about 82.5% for traditional farming. As returns rose above variable costs in modern agriculture by about 141% for
traditional farming. The ratio of return on cost is about 1.3, 0.75 for both traditional and modern agriculture respectively. The total marginal rate of return (MRR) to 27.3 %, this indicator shows the level of returns as a result of the unity of the money directed to the purchase of new technologies squash.

The artichoke is one of non-traditional export of vegetables crops, Consisted research problem that Egypt produces almost five global production of artichokes, but the volume of exports is not commensurate with the production and the large amounts of artichoke exports are made in the image fresh and not processed and thus lower the value added to exports of artichokes, And artichoke market is characterized by vacillation and of price stability as a result of its association with the external marketing, which affects the incomes of farmers and workers artichoke processing stations. Targeted
research in the study of both the time development and current status of the production of artichokes in the Egyptian agriculture and the province of the lake, the most important foreign market indicators Egyptian artichoke, the
value chain of the artichoke analysis of Kafr Al-Dawar Status, general characteristics of the value chain, identifying the strengths and weaknesses of the episodes of the value chain of the artichoke Kafr Al-Dawar Status points.
The results of the study showed that Egypt is the second largest in the world as the most important producing and exporting countries, while classified all of Italy, France and Spain of the most important producing and
importing and exporting. The amount has also taken and the value of Egyptian exports of artichokes years an increasing trend during the study

ESTIMATING TECHNICAL EFFIECIENCY FOR IMPORTANT EGYPTION GOVERNORATES IN SUGAR BEET OUTPUT
text
article
2016
eng
The research is performed to estimating the technical efficiency for important Egyptian governorates in sugar beet output. In order to fulfill the above objective the research depends on the quantitative
analysis for estimating the technical efficiency with using Data Envelopment Analysis (DEA). The research had come to some important results and conclusion can be summarized as follows.
1- With measuring the technical (productivity) efficiency for sugar beet for different governorates, with using (DEA) showed that: (a) It had been achieved for Dakahlia, Sharkia, Fayoum and Assiut governorates, the average for the technical efficiency was about 0.97,this indicates to can increasing it with about 0.03 with using the same
economic resources. (b) All of governorates are increasing return of scale except Assiut governorate had fixed return of scale. (c) Founding slacks in using capital was about Garbia governorate, addition to found
slacks in using labor was about 133.57, 70.82 and 21.17 for Mania,Kafr-Elsheikh and Beny-souif governorates.
2- The economic implications of achieving the technical efficiency of sugar beet at the Agriculture level., (a) This achieving will increase the sugar beet output equivalent expands of Agriculture land by 0.12, 8.99,2.13 and 2.24 thousand feddan with total was about 13.48 thousand feddan. (b) The governorates respectively as well as achieving saving
of irrigation water at 0.0003, 0.0225, 0.0064 and 0.0067 billion cubic meters with total was about 0.036 billion cubic meters respectively. Lastly in light of the results the research can suggest some recommendation such as: (1) Concentrate cultivation of sugar beet in the governorates of high productivity (Assiut and Menia) and
increasing the productivity efficiency for governorates had medium and low productivity, (2) Using the modern technology for devolving the sugar been output, (3) Saving and devolving of the production efficiency inputs with optimal quantities and in suitable time.

2016
eng
The present study was conducted at laboratory of food technology department, faculty of agriculture, Kafrelsheish University. This research was carried out study the most suitable conditions for increasing precent of resistant starch for
both of rice and corn starches as they considered the main sources of starch in food industry in Egypt. The following experiments and tests were done: preparing resistant starch (RS3) through overlapping among several factors
that is number of cooking cycles in autoclave, cooling, cooking time and the percentage of suspended starch of rice and corn starch in water. The resistant starch was estimated and the laboratory digestion of starch, and amylose and
amylopectin content were estimated, the most appropriate conditions to get the highest percent of resistant starch (RS3) from the rice and corn starch was known. The physical properties of resistant starch was studied in comparison
with native starch. The data showed that the best conditions to obtained the highest yield of resistant starch (RS3) from corn starch was after16 autoclaving- cooling cycles with 60 min autoclaving time at 1:4 starch /water
ratio, this yield was 28.50 % this equal to 8.14 fold of that present in native rice starch ( 3.50 %). On the other hand, the best conditions to obtained the highest yield of resistant starch (RS3) from rice starch was after 20 autoclavingcooling
cycles with 30 min autoclaving time at 1:5 starch /water ratio. At these conditions, RS equal to 6.12 fold of that present in native starch (4.90 %).
