deficit irrigation is an essential optimization method for water consumption in irrigated lands. in order to investigate the effects of deficit irrigation on growth, yield and quality traits of two tomato (lycopersicon esculentum mill.) cultivars a factorial layout based on randomized complete block design with three replications was conducted in agricultural research station of miandoab during...

in order to study effect of foliar application of iron and zinc on yield and yield components of autumn rapeseed (brassica napus l.) under limited irrigation an experiment was conducted at research farm of agricultural faculty of urmia university in 2009. the experiment was designed in split plot based on randomized complete block design with 3 replications. treatments were drought (irrigation ...

Crop productivity is improved by ecosystem services, including pollination, but this should be set in the context of trade-offs among multiple management practices. We investigated the impact of pollination services on coffee production, considering variation in fertilization, irrigation, shade cover, and environmental variables such as rainfall (which stimulates coffee flowering across all pla...

The two-location field experiment was conducted to study the possible alleviation of droughtstress effects on red bean by ultrasonication and 24-epi-brassinolid. Locations were AgriculturalResearch Center in Shahrood, Iran and the other in bean farm, 40 km off Shahrood city in 2015.Experiment factors included irrigation of main plots at three levels of normal irrigation (60 mmevaporation from e...

canola genotypes reaction to stopping irrigation was surveyed. this experiment was carried out as a split plot randomized block design whit three replications in the safiabad argicultural research center for two years. main plot was considered of different levels of stopping  irrigation (stopping irrigation at the ending flowering, poding, 10%  and 30% ripening of pods in main stem ) and sub pl...

Saffron is grown in arid and semi-arid regions in Iran in late autumn, winter and late spring with rainy season. It should be irrigated by supplemental basin irrigation. Since rainfall is usually delayed in autumn, therefore, a pre-flowering irrigation of about 100 mm is needed. In areas with a seasonal rainfall of 600 mm a post- flowering irrigation of about 50 mm is adequate for economical yi...

two-year experiments was conducted to find the effect of value and times of supplementary irrigation on water requirement and yield production of three new wheat cultivar namely (‘w33g’, ‘cross alborz’ and ‘bahar’) in three replicate randomized complete block factorial experiments since 2009-11. experiments were performed at the campus of agriculture and natural resources of razi university lys...

introduction: lack of water and deterioration in the quality of soil and water resources are considered to be the prime cause of reduced crop yield in arid and semi-arid regions ‘more crop per drop’ by trickle irrigation, deficit irrigation, and uncommon water are the best strategies for mitigating water crises. different irrigation management strategies are needed to increase production in dif...

Dwindling water resources combined with meeting the demands for food security require maximizing water use efficiency (WUE) both in rainfed and irrigated agriculture. In this regard, deficit irrigation (DI), defined as the administration of water below full crop-water requirements (evapotranspiration), is a valuable practice to contain irrigation water use. In this study, the mechanism of paclo...
