in arid and semi arid, seedling emergence and establishment are key stages for final plant density in chickpea production. drought stress, especially at the end of the growing season, is one of the factors which decrease a main part of chickpea grain yield in these areas. therefore the aims of this study were assess to the effects of hydro priming and hormonal priming by gibberellin and abscisi...

Determining environment – associated alterations in grain yield is important in yield assessment under drought stress. Therefore this study was carried out to determine the correlation coefficients and direct and indirect effects of effective components on yield in four drought - tolerant and susceptible cotton cultivars. Cotton cultivars were considered as sub plots and 3 levels of irrigation ...

This experiment was laid out in order to evaluate the effects  of different biofertilizers on yield components of barley. The experiment was a factorial design with three replications. Treatments were three nitrogen biofrtilizers (Nitroksin, Nitrokara and Supernitroplass) and three phosphate  biofrtilizers (Phosphate barvar2, Biozarr and Superplass) with control for them and yield components we...

in this thesis, first the notion of weak mutual associativity (w.m.a.) and the necessary and sufficient condition for a $(l,gamma)$-associated hypersemigroup $(h, ast)$ derived from some family of $lesssim$-preordered semigroups to be a hypergroup, are given. second, by proving the fact that the concrete categories, semihypergroups and hypergroups have not free objects we will introduce t...

Limited information is available on the effect of residues rates and slope direction on dryland wheat (Triticum aestivum L.) yield.  This study was carried out to determine the effects of residues rates and tillage direction on grain yield and yield components of the Sardary wheat in a dryland region in Zanjan. Five wheat residues rates (0, 25, 50, 75 and 100% surface cover) were applied and i...
