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...

the effect of drought stress on yield and components of three varieties of autumnal rapeseed in the south ‎eastern region of isfahan, utilizing four irrigation regimes (i.e. no irrigation from flowering stage on, no ‎irrigation from the podding stage on, no irrigation from grain filling stage on, and a normal irrigation regime ‎after 80 mm evaporation from class a evaporation tube) were studied...

introduction sunflower (helianthus annuus l.) is one of the most important oil crops in the world. iran is climatically regarded as an arid and semi-arid region in the world, where the lack of precipitation and its inappropriate distribution, high temperature and extensive evaporation makes the irrigation the main way for meeting plants water demand. hence, studying the effect of irrigation on ...

in order to evaluate the effects of drought stress and methanol foliar application on some quantitative and qualitative traits of soybean (cv. viliamz), a split plot experiment was conducted based on randomized complete block design at the faculty of moghan research farm in 2011. treatments were three levels of drought stress based on irrigation at depletion of 40, 55 and 70 percent of availabl...

evaluating of some physiological indices for recognizing water deficit effects, selecting water deficit tolerant oilseed rape genotypes and also evaluation of drought effects on seed and oil yields and its components were the goals of this study. the experiment was conducted as factorial based on a randomized complete blocks design with three replications in east azarbaijan research center for ...

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...

Irrigated rapeseed (Brassica napus L.) cultivation is currently expanding in rotation with winter cereals in Iran where its reproductive growth is often exposed to water deficit in many parts, particularly in the south. A two growing seasons (2006-2008) field experiment was conducted at the Experimental Research Center, Shiraz University to study the effects of water stress at different growth ...
