during grain development, appropriate water status of soil has key importance for starch accumulation in grains and hormone changes. for this, the study carried out on two iranian wheat cultivars pishtaz and karaj 3 in a factorial experiment based on randomized complete block design with three replications under irrigated and drought in a field experiment at research farm of agriculture college...

In West Bengal, it is most promising to tender early maturing high yielding varieties of rice since they can fulfil their life cycle successfully within short period of persisting cool temperature. The objective of this present investigation was to identify these high yielding early maturing genotypes of rice having quality characters and higher performance in grain yield. A study was conducted...

dry land salinity is one of the major problems affecting agricultural products. the main consequences of plant exposure to salt stress are water deficit and ion excess, which lead to several morphological and physiological changes. in order to evaluate the effect of salinity on some physiological characteristics of 8 spring rapeseed cultivars, an experiment was conducted in the greenhouse at ya...

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 determine the practical method to predict economic production of wheat in competition with feral rye by using regression models, a factorial experiment was carried out based on randomized complete block design with three replications in dargaz. iran. experimental factors were included wheat cultivars (sayson, alvand, chamran and sepahan) and feral rye densities (0, 20, 40, 60 and 80...

in this study, the performance of aquacrop model to predict yield production of winter wheat (roshan and gods varieties), water and solute balance of soil profile was evaluated under water and salinity stresses. field experiments were conducted with three levels of saline irrigation water including: s1, s2 and s3corresponding to 1.4, 4.5 and 9.6 ds/m, respectively, and four levels of irrigation...

in order to study on adaptability and grain yield stability of eight bread wheat cultivars (alvand, alamout, zarrin, navid, azar 2, sabalan, omid and bezostiya), a rcbd experiment was conducted during three cropping seasons (2007-2010) at six locations (sanandaj, gorveh, marivan, divandarreh, saggez and baneh). simple analysis of variance (anova) and combined anova for three years in each locat...

A field experiment was conducted to evaluate the crop water stress index (CWSI), grain yield and canopy temperature of triticale under two irrigation regimes at Research Station of College of Agriculture and Natural Resources of Darab, Shiraz University, in 2013. A split plot design was used with three triticale cultivars (Sanabad, ET-83-3, and ET-84-5), as sub-plots and four levels of irrigati...

an experiment was conducted to determine the effect of five plants densities (100,200,300,400 and 500 grain m-2) on yield and its components in three rain fed barley cultivars (ezeh, mahor and dopar). a factorial experiment based on randomized complete block design with three replications was conducted in agricultural research center of khorramabad city in the east of iran (in 2006-2007). in th...
