At present, the shortage of water resources has become a serious constraint to the further development of social economy. The optimal allocation of multi-water resources is valuable for agricultural water management in arid and semi-arid regions. However, traditional deterministic programming does not solve the complex water resources allocation in irrigation systems. Furthermore, previous allo...

Field water balance measurements using monolithic lysimeters were used in validating the Cupid-DPE model for predicting water loss partitioning during sprinkler irrigation from a moving lateral system fitted with impact sprinklers and spray nozzles. The model combines equations governing water droplet evaporation and droplet ballistics with a comprehensive plant-environment energy balance model...

to study the effects of phosphate and zinc sulfate fertilizers application methods on the yield and yield components of maize under water stress a randomized complete block with split plot factorial arrangement with three replications at research farm of the bu ali sina university was conducted in 2014. three levels of irrigation after 60, 90 and 120 mm evaporation from evaporation a pan was as...

Drought stress is considered as the most important limiting factor for growing of crops such as maize. Under low irrigation conditions, proper nutrition of plants can improve the effects of drought stress. This experiment was carried out in order to investigate the effect of nutrition management along with application of zeolite on agronomic traits of two hybrids of maize under deficit irrigati...

To evaluate sugar beet germplasm for identifying drought tolerant genotypes, precise methods are required for application of drought stress. A field experiment carried out as split arrangments in randomized complete block design with four replications in Karaj, Iran in 2007 and 2008. Main plots consisted of eight irrigation treatments with furrow and tape drip irrigation methods after 30 mm (ex...
