to evaluate the effect of different levels of nitrogen fertilizer on growth indices and competitive ability of canola (brassica napus l.) against wild mustard (sinapis arvensis l.), a split plot trial based on a randomized complete block design with three replications, was carried out at agricultural faculty of bu-ali sina university, during 2008-2009. experimental factors were amounts of nitro...

One of the methods for achieving more yields is to use seed priming technique correctly. When it comes to using seed priming, practically important issues should be taken into account including interval between priming to planting and conditions for storage of primed seeds. Thus, it is very crucial to be informed of duration and temperature for storage of primed seeds. This research seeks to co...

At percent, Zn stress tolerance using novel genetic resources is an important mitigation strategy for plant breeding. In this study, thirty-five durum wheat genotypes with different growth habits were evaluated under normal (non-stress) and Zn deficient stress during the 2014-15 cropping season. A total of ten Zn stress tolerance indices including stress tolerance index (STI), relative zinc-def...

in order to study physiological characteristics of rainfed bread wheat genotypes, an experiment was conducted with 20 genotypes in a randomized complete block design with 4 replications under rainfed and supplementary irrigation conditions. this experiment was carried out at the dryland agricultural research institute (dari) in maragheh during 2007-2008. to determine growth indices, sampling wa...

in order to study grain yield, yield components and growth indices in wheat, the experiment was carried out with five wheat cultivars at rbcd arrangement with 4 replications at gorgan university of agricultural sciences and natural resources. the cultivars included zagros, tajan, kohdasht, durum and n81-18 line. to measure studied traits (leaf, stem and shoot dried weight and leaf area) fifteen...

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 ...
