Water stress is one of the major abiotic stresses in agriculture worldwide. In order to assess photosynthesis response and grain yield of 25 wheat genotypes under water deficit (post-anthesis stress) conditions, a 2-year study (2010-12) was carried out as a split-plot arrangement using randomized complete block design with three replications. The most sensitive gas exchange variable to water de...
to study the effects of zabol wastewater treated with two kinds of fertilizer (manure and chemical fertilizer) application vs use of ordinary water on grain yield and yield components in corn (kosc704) a field experiment was conducted at the university of zabol, iran during 2007 growing season. the statistical plan selected was a split plot one of three replications. the treatments were compris...
a one dimensional dynamic model for a riser reactor in a fluidized bed catalytic cracking unit (fccu) for gasoil feed has been developed in two distinct conditions, one for industrial fccu and another for fccu using various frequencies of microwave energy spaced at the height of the riser reactor (fccu-mw). in addition, in order to increase the accuracy of component and bulk diffusion, instanta...
In order to determine the response of yield and seed yield components of red bean )Phaseolus vulgaris L. ( genotypes to delay in planting, this study was conducted in Factorial experiment based on a RCB design with 3 replications in the Jahad-Keshavarzi Research farm of Miyaneh in 2006. Factors included cultivars in three levels(Naz, Gole and Sayad) and planting date in three levels (5 and 20 ...
in order to investigate the effect of water stress at heading stage on grain yield and yield components of eight wheat cultivars, in 2008 year a research was conducted in the two regions esfahan and ardestan by using split plot in a randomized complete block design with three replications which that two irrigation treatments included custom and late season water stress were main factor and 8 wh...
terminal heat and drought are the main constraints for wheat production in the vast and diverse semi-tropical rainfed regions of iran. high temperature stress during wheat’s reproductive stage is particularly detrimental, reducing both individual kernel weight and kernel number. identification of adapted genotypes can improve grain yield and its stability under heat stress conditions. selection...
in order to deliberate correlation coefficient between grain yield and yield components among 31 cowpea genotypes under normal irrigation (non-stress) and drought stress (water withholidng after flowering stage until maturity) an experiment was performed in a randomized complete block design (rcbd) with three replications at research field of university of tehran located at karaj during 2011-20...
To study the effect of seed priming on seedling emergence characteristics of lentil and evaluate its interaction with drought stress at flowering stage, an experiment was carried out as split plot in a randomized complete block design with three replications at research station of Bu-Ali Sina University, Hamedan, Iran. The main factor consisted drought stress with two levels (conventional irrig...
Drought stress is the most important factor restricting both growth and crop yield formation under arid and semi-arid conditions. In a field experiment, the effects of foliar application of growth regulators of auxin at three levels (0, 20 and 40 mg/L) and cytokinin at three levels (0, 50 and 70 µmol) at pollination stage on yield and yield components of a bread wheat (Shiraz cultivar) and duru...
one of the soil and water management practices in order to delay drought stress under water deficit condition; is superabsorbent application. in order to study the effect of superabsorbent application on yield and yield components, two antioxidant enzymes activity and water relation of two canola hybrids under terminal drought stress condition, a research was carried out in ahvaz climate condi...
