abstract saffron (crocus sativus, l.) is one of the most important economical crops for khorasan farmers. almost all saffron yield in iran comes from khorasan provinces. first irrigation times is the crucial factors which affect the amount and quality of yield based upon an on farm investigation it was found that when air temperature reaches to 12 ۫c the most amount of flower is yielded. also it...

Cytokinins may reflect soil water status and regulate rice (Oryza sativa L.) grain filling. This study investigated the changes in cytokinin levels in rice plants and their relations with grain filling under alternate wetting and drying irrigation. Two 'super' rice cultivars were field grown. Three irrigation regimes, alternate wetting and moderate soil drying (WMD), alternate wetting and sever...

A field experiment was performed in order to evaluate the effects of irrigation and application of K fertilizer on seed storage proteins  in chickpea, ILC-482 cultivar. Experiment was performed in factorial using randomized complete block design with three replications. In this experiment, two factor consist of irrigation in three levels (I1= non irrigation and I2= irrigation in flowering stage...

in order to assess the performance of two soybean cultivars produced in two regions including karaj and moghan to drought stress at reproductive stages and also the impact of drought stress on yield and its components, oil and protein percent, an experiment was conducted as a split factorial based on complete randomized block design in three replications in agriculture faculty of tarbiat modare...

to study the effect of sowing date and a single irrigation (si) on yield and yield components of barley, a field experiment was conducted in dryland agricultural research institute (maragheh, iran) in 2004-06 cropping seasons, using a split plot based on a randomized complete block design with 3 replications. main plots were assigned to 3 levels of sowing date (early, normal and late). sub-plot...
