introduction: one of the serious problems in the further development of maize cultivation is increasing irrigation efficiency. using conventional irrigation causes a shortage of water resources to increase the acreage of the crop. with regard to the development of maize cultivation, agronomic and executable methods must be studied to reduce water consumption. using drip irrigation system is mos...

introduction: designing and management of sprinkler irrigation systems depend on the situation and location of its implementation and often rely on professional and long-term tests (9). having a good irrigation system depends on knowledge of the relationship between soil, water, plants, irrigation scheduling, the required amount of irrigation water to the water-holding capacity of soil, climate...

low level of efficiency is a main problem of surface irrigation systems that is due to their poordesign and management. furrow inflow rate and cut off time are the most important design parametersthat affect the efficiency of furrow irrigation. in this study, furrow irrigation condition of amir kabiragro-industry sugarcane fields was simulated with winsrfr3.1 model. then, irrigation performance...

The withdrawal of water for i r r igat ion in the d ryer regions of Mexico already accounts for some 91% of potential availabil i ty. Fur ther expansion of i r r igated acreage, therefore, must re ly more on increased water use efficiency ra ther than increased supply from engineering works. A pr ime ins t rument to br ing about such an improvement could be an appropriate water pr ic ing s t ru...

water shortage is the most important factors on crop production in the world. several methods of deficit irrigation are solutions for reduction of irrigation water. to understand the effects of conventional deficit irrigation and partial root zone drying treatments on yield, yield components and water use efficiency of sunflower (farrokh cultivar), one study was carried out. the research was co...

An experiment was conducted to study the effects of different soil water potential (SWP) on soil water content, hot pepper’s yield, water consumption and water use efficiency (WUE) under plastic-mulched drip irrigation in the North-West China in order to find a suitable SWP to guide the pepper irrigation. Five treatments were set based on SWP, they were -10kPa (N1), -20kPa (N2), -30kPa (N3), -4...
