this study was performed in order to evaluate the effects of drought stress and nitrogen fertilizer on phenology, morphology and yield of four cultivars of chickpea. this experiment was performed in a split-factorial using randomized complete block design with three replications. drought stress treatment stood in main plots (in three levels) consisting of no drought stress (control), moderate d...

In order to study the effect of phosphorus fertilizer and less irrigation on grain yield of the forage Millet, an experiment was carried out in 2010. The experimenta design was the split plot based on a randomized complete block with three replications. The main factor was two varieties of forage millet (Bastan - Pishahang), three levels of less-irrigation as sub plot (non-stress conditions, wa...
