Research ArticleOpen accessIn the abstractEffect of Super Absorbent Application on Antioxidant Enzyme Activities in Canola (Brassica napus L.) Cultivars under Water Stress ConditionsH. R. Tohidi-Moghadam, A. H. Shirani-Rad, G. Nour-Mohammadi et al.Problem statement: Drought stress significantly limits Canola (Brassica napus L.) growth and crop productivity. Hence, efficient management of soil moisture and study metabolic changes which occur in response to drought is important for agricultural production of this Crop. Approach: For a better understanding of drought tolerance mechanisms and improving soil water content management strategies, an experiment was laid out in … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 3 · 30 Sep 2009 · 8,603 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigating the Effect of Three Nitrate Fertilizers on Nitrate Leaching under the Root Zone in Clay Loam SoilThamer Ahmed Mohammed, M. Nooshin, Megat Johari Megat Mohd. Noor, A. LiaghatProblem statements: Nitrogen fertilizer is recognized as an important factor in crop’s yield level, however more application of N fertilizers in the soil have some adverse effects on environment and especially on groundwater contamination. Perception and recognition the factors influencing nitrate transport through soil profile is helpful for fertilizer management to minimize adverse impacts on environment and nitrate leaching below … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 7,064 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy of Performance Parameters of Threshing Unit in a Single Plant ThresherEzzatollah Askari Asli-Ardeh, Yousef Abbaspour-Gilandeh, Saeid AbbasiProblem statement: The rice is the one of important crop in the word which is cultivated at the extensive area of Iran. Yield of crop is a factor which is investigated in the breading researches. Usually, for threshing of crops at these studies, single plant thresher is used.
