abstract water is a main factor in production of crops. optimizing the usage of water is essential especially in iran which is a dry and semi-dry country. investigation on the effect of different irrigation treatments on chilo suppressalis walker (lep.: crambidae), as the most destructive rice pest, can be an efficient strategy in optimizing usage of water in integrated crop management (icm). i...

one of the soil and water management practices in order to delay drought stress under water deficit condition; is superabsorbent application. in order to study the effect of  superabsorbent application on yield and yield components, two antioxidant enzymes activity and water relation of two canola hybrids under terminal drought stress condition, a research was carried out in ahvaz climate condi...

root and crown rot of sugar beet caused by rhizoctonia solani ag2-2 is a destructive disease in the main sugar beet growing areas. use of resistant cultivars is the most effective and environmentally safe way to control the disease. in order to find resistant genotypes, 70 sugar beet lines together with resistant and susceptible checks were evaluated against a highly virulent isolate of r.solan...

concerning limitation of water resources, determination of the least water that can lead to the maximum yield is of great importance in crop production. in order to evaluate effects of deficit irrigation on grain yield and water use efficiency of some wheat )triticum aestivum) cultivars under different climatic conditions, two similar field experiments were conducted in 2004 in agricultural res...

water sources optimizing required a suitable irrigation program. different material can use to increase water use efficiency. superabsorbent is one of the materials where used in around the world. these materials put in the soil and absorb water so that reserved water is usable by plant in the time of drought stress and they can reduce stress and lead to prevent yield loss. therefore, the exper...

abstract this study was conducted to determine the impacts of different drip irrigation method and amount of water on yield and water use efficiency of tomato in varamin agricultural research center, iran. the study was done during two years. experimental design was randomized complete blocks design (rcbd) in split plot with three replications. three different drip irrigation method; surface dr...
