Water shortage and low phosphorus (P) availability limit yields in soybean. Roots play important roles in water-limited and P-deficient environment, but the underlying mechanisms are largely unknown. In this study we determined the responses of four soybean [Glycine max (L.) Merr.] genotypes [Huandsedadou (HD), Bailudou (BLD), Jindou 21 (J21), and Zhonghuang 30 (ZH)] to three P levels [applied ...

abstract soilless culture of greenhouse vegetables has been a fast developing section in iran during recent years. most growers use hydroponics systems with artificial substrates. some of the used substrates have low water retention which results in wasting a great deal of solution. on the other hand, low vigor of cucumber root in water and fertilizer absorption, especially in low media tempera...

in order to investigate drought stress and plant density the yield, yield components and protein of spotted bean grain (cultivar talash), an experiment was carried out as split plots in randomized complete blocks with three replications in yasouj, in 2012. factors of the test including irrigation in three levels; without stress (control treatment), water stress in vegetative stage (interrupting...

in order to identify drought stress tolerance in rapeseed, nine commercial rapeseed cultivars (opera, karaj1, karaj2, karaj3, zarfam, okapi, talayeh, licord and modena) were evaluated under two conditions (normal and drought stress) in kangavar region in the west iran in 2014-2015 growing season. this research was carried out in a split plot experiment based on completely randomized design in f...

this study investigated the effect of sowing date and limited water allocation management for single irrigation on the grain yield of rainfed barley. the experiment was a split-split plot arranged in a randomized complete block design with three replications from 2004 to 2006 at the main station of the dryland agricultural research institute at maragheh. the treatments comprised three sowing da...

to study the effect of planting pattern and water quantity on potato yields under drip irrigation, this research was conducted using a split plot based on a randomized complete block design with four replications in three regions (mashhad, ardebil and damavand, iran) during 2003-2004. nine treatments were used. the main-plots were three levels of irrigation: 100%(i1), 80%(i2), and 60%(i3) of cr...

in order to evaluate the effect of salicylic acid on yield and yield components of bean genotypes under water deficit stress, an experiment was carried out as a factorial split plot design with three replications in research farm bu ali-sina university (hamadan, iran) during 2009. stress levels: consist of vegetative water stress, reproduction water stress and without water stress (control) and...

Drought, particularly terminal drought, reduces the yield of chickpea (Cicer arietinum L.). Terminal drought tolerance and water use patterns were evaluated under controlled conditions in 10 genotypes of desi chickpea. Withholding water from early podding reduced vegetative growth, reproductive growth, seed yield, and water use efficiency for seed yield in all genotypes. The genotype Neelam, wh...

for determination of water stress effects in different growth stages of sugar beet and optimum water usage on quantity and quality of sugar beet, this study was performed using randomized complete blocks design in factorial experiment with 12 treatments and 4 replications from 1999 to 2001 in agricultural research center of hamadan. the first factor was non-irrigation in 3 stages of growth (s1-...
