Irrigation is an inevitable part of agriculture which determines crop yield and thus food security. In modern era of agriculture, crop yield is determined on the basis of crop production per unit of water-use instead of crop production per land unit area. Deficit irrigation is introduced as a strategy for controlling water resources that leads to water resource preservation. Date palm requires...

today as freshwater resources become scarcer, wastewater use is a major incentive option for conserving and expanding available water supplies. the aim of this research was to investigate the impact of normal irrigation water (well water), chemical fertilizer, and treated urban wastewater effluent on yield quantity and quality of broccoli under micro irrigation system. the accumulation of chemi...

research on crop response to deficit irrigation is important to reduce agriculture water use in areas where water is limited resource. using drought resistant landraces with irrigation scheduling based on phenological stages in semi-arid and arid regions may provide an opportunity to optimize irrigation efficiency and water savings in these regions. in order to evaluate of yield and yield compo...

Agricultural irrigation in the middle reaches of the Heihe River Basin consumes approximately 80% of the total river water. Whether the irrigation depth matches the water uptake depth of crops is one of the most important factors affecting the efficiency of irrigation water use. Our results indicated that the influence of plastic film on soil water δ(18)O was restricted to 0-30 cm soil depth. B...

in order to study the effect of irrigation cut on dry matter remobilization and some of agronomy traits on spring barley, a field experiment was conducted by using a split-plot based on randomized complete block design (rcbd), in three replications, at agricultural and natural resource research center of ardebil, in 2009. irrigation treatments included normal irrigation (as local routine in pas...
