So, a crucial role for agriculture and its sustainability should be identified. Concerning the sustainable agriculture, it means how to supply the humans with previous essential living supplies without any compromising of needs for future generations. This needs definitely the integration among the environment and its quality, economic profitability, social and economic equity as well as maintaining or conservation of the water and land resources. Moreover, farming systems should use fewer inputs and natural resources without any reducing of agricultural yields in order to reach economic profitability, the safety of the environment and social fairness. Therefore, this review will focus on the sustainability of the agriculture from a holistic overview.}, keywords = {Sustainable agriculture,soils,water,energy,Kafrelsheikh University}, url = {https://jsas.journals.ekb.eg/article_3609.html}, eprint = {https://jsas.journals.ekb.eg/article_3609_2e2755020eff0d428ec9a81a9faaefb4.pdf} } @article { author = {Zommara, M. and Imaizumi, K.}, title = {In Vitro Antioxidant Activity of Chufa Tubers (Cyperus esculentus L.)

Incorporation of 1 mg/ml of chufa oil, water or ethanol extracts of the tubers to phosphatidylcholine (PtdCho) liposomes displayed different antioxidative activity. All fractions possessed antiperoxidation activity in ferrous ions dependent peroxidation stress and in free radical mediated peroxidation by the water soluble initiator 2,2'-azobis (2-aminopropane) dihydrochloride (AAPH), while the water extract possessed the strongest effect. However, in the lipid soluble free radicals initiator 2,2'-azobis (2,4-dimethylvaleronitrile) (AMVN) mediated peroxidation, the antioxidant activity was found only by the oil fraction. The antioxidant activity of chufa oil may be attributed to its fatty acid profile and vitamin E content. Chufa oil contains about 72% of monounsaturated fatty acids, mainly oleic acid and 18.6 mg/100g of vitamin E. The resistance of chufa water and ethanol extracts may be attributed in part to its isoflavones content (20.9µg/g).}, keywords = {Chufa,olive oil,anhydrous milk fat,liposome,Antioxidant activity,lipoperoxidation,ferrous ions,AAPH,AMVN}, url = {https://jsas.journals.ekb.eg/article_3610.html}, eprint = {https://jsas.journals.ekb.eg/article_3610_61abd8fcc4079240876017675a5f91c7.pdf} } @article { author = {Elgaml, Nabil and Moussa, M.A.M. and Saleh, A.

Also, these cultivars exhibited highly significant differences for all drought tolerance indices.

Group 1: diet including 0 % wheat bran (control1), Group 2: diet including 10% unfermented wheat bran (control 2), Group 3: diet including 10% wheat bran solid fermented by Trichoderma longibrachiatum (SF1). All diets were iso-caloric and iso-nitrogenous. Feed and water were provided ad libitum. The statistical evaluation of growth performance at the 5th week of age indicated significant increase in the average live body weight of birds fed with fermented wheat bran which recorded (1640 g) compared with the control-1 (1147.7g) and control-2 (1363.5 g). Feed consumption recorded significant increase to 3915.6 g/ bird, which returned to the best palatability of fermented feed. It was clearly sustained that the best significant feed conversion was recorded in group treated with fermented wheat bran (2.39), while unfermented WB group (2.41) compared to control-1(2.69). The cross sections in duodenum revealed no histopathological features related to such fungi and showing normal histological structure.
