experiment was conducted as split plot in a randomized complete block design with three replications in kermanshah to shed lights on economic analysis of deficit irrigation and integrated application of biological and chemical fertilizer son cultivation of medicinal plant borage (borago officinalis l). irrigation tritments include: a) 30% less water than crop requires invegetative, b) inreprodu...

Irrigated agriculture is facing a serious problem of water scarcity, which could be mitigated by optimizing the application regulated deficit irrigation (RDI) strategies. For this reason, aim our study was to determine thresholds based on direct status indicators apricot trees under RDI maximize productivity. Three treatments were tested: (i) Control (CTL), irrigated at 100% crop evapotranspira...

abstract: deficit irrigation technique can be used for produce more yield for every unit of irrigation water, and cause to increase crop economical benefit. main purpose of deficit irrigation is high water use efficiency with decreasing in irrigation sufficiency. in this research potential of cropwat model in deficit irrigation management for two crops, wheat and barley in karaj climate was stu...

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...

the price of water in agriculture plays an important role in the water allocation management. therefore, the optimum strategies of cropping pattern could be designed when water price analysis are considered in a predetermined economic framework. in the present study, a programming model was developed using the genetic algorithm for optimal water allocation in the eastern north of khuzestan prov...

in recognition of the value and limitations of available water resources in agriculture and the occurrence of periodic drought in iran, water conservation and optimal usage of available water is essential. the main objective of this study was to optimize field water management and cropping patterns using deficit irrigation. the effect of reducing water consumption on different growth stages usi...

this research was conducted at the shahrood agricultural research center in 1382 and 1383 to study the effect of alternate furrow irrigation on potato yield and its economic evaluation. the experimental design was a randomize complete block design and the treatments were: every furrow irrigation (efi), fixed alternate furrow irrigation (fafi), variable alternate furrow irrigation (vafi), fixed ...
