Wheat growth in response to soil water deficit play an important role in yield stability. A field experiment was conducted for winter wheat (Triticum aestivum L.) during the period of 2002–2005 to evaluate the effects of limited irrigation on winter wheat growth. 80%, 70%, 60%, 50% and 40% of field capacity was applied at different stages of crop growth. Photosynthetic characteristics of winter...

in order to study the effect of deficit irrigation at reproductive growth stages on growth and grain yield of four sunflower cultivars namely: azargol, allstare, alison and euroflor, an experiment was conducted during the 2007 growing season at the experimental field of the agricultural faculty of bu-ali sina university. the experimental design was a split plot one, based upon a randomized comp...

this study was carried out in the agro-industry complex of gohar kouh, khash in iranshahr. a split-plot experiment based on rcbd was employed with three irrigation intervals including 1: 30 day interval 2: 40 days of irrigation interval 3: 60 day irrigation interval along with three levels of nitrogen application including 1: no nitrogen fertilizer 2: 750 grams of nitrogen fertilizer per tree 3...

in order to investigate the effects of different irrigation regimes on yield and growth indices of three chickpea cultivars, an experiment was conducted during the 2007 growing season at mashhad (iran). six irrigation regimes including i1; full irrigation, i2; irrigation at branching, i3; irrigation at flowering, i4; irrigation at pod formation, i5; irrigation at seed filling stage and i6; dry ...

in order to study effect of foliar application of iron and zinc on yield and yield components of autumn rapeseed (brassica napus l.) under limited irrigation an experiment was conducted at research farm of agricultural faculty of urmia university in 2009. the experiment was designed in split plot based on randomized complete block design with 3 replications. treatments were drought (irrigation ...

This study was conducted to assess the effects of irrigation and plant growth promoting bactera on seed yield and qualitative characteristics of Black cumin (Nigella sativa L.) at the Experimental Station of the Research Institute of Forest and Rangeland, Damavan region, Iran. A split-plot experimental design, based on Randomized Complete Block Design (RCBD) with three replications, was used. I...

Crop show morphological and physiological responses to microbial, physical or chemical factors which are known as elicitors. Chitosan is a natural biopolymer modified from chitin, which is the main structural component of squid pens, cell walls of some fungi and crab shells. Water stress is one of the most important abiotic stresses that affects plant physiological and morphological traits. In ...

to evaluate the yield and yield components in additive intercropping system of grain sorghum (sorghum bicolor l.) and cowpea (vigna unguiculata l.) under limited irrigation condition, an experiment was conducted in research farm of college of agriculture, university of tehran, during spring 2006. the experimental treatments were arranged in split plots based on a complete randomized block desig...
