In order to determine the best developmental stage of three common bean cultivars (Talash, COS16 and Khomain) at which maximum seed quality is attained under different irrigation regimes (I1-irrigation after 60 mm, I2-irrigation after 80 mm and I3-irrigation after 100 mm evaporation from class A pan), a split plot experiment (using R.C.B. design) with 3 replications was conducte...

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...

introduction lentil with about 28 percent protein occupies the second after soybean. it is one of the major crops in developing countries as a complement to cereals and is an excellent source of protein and amino acids in the diet. results of studies shown that for most crops, including lentil, the occurrence of drought stress in some phenology stages cause irreparable damages to yield. therefo...

There is a need to optimize water-nitrogen (N) applications to increase seed cotton yield and water use efficiency (WUE) under a mulch drip irrigation system. This study evaluated the effects of four water regimes [moderate drip irrigation from the third-leaf to the boll-opening stage (W1), deficit drip irrigation from the third-leaf to the flowering stage and sufficient drip irrigation thereaf...

sesame could be an appropriate oilseed crop for water limited environments. this research was aimed at studying growth, leaf chlorophyll fluorescence, proline content, yield and yield components of sesame cultivars under different moisture regimes. a 4-replicate split plot rcbd field experiment was conducted at the lavark research farm, college of agriculture, isfahan university of technology, ...
