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...
knowledge of the relation between agronomical traits with economical yield is very important in crop improvement and breeding. in order to study of genetic diversity and identifying yield components, 568 kabuli type germplasm and 390 desi type chickpea germplasm that were available in pulses collection of faculty of agriculture, university of tehran, was investigated in this research in 2009 in...
nowadays,tourism industry considered as one of the main sources of income of a country.unfortunately and despite of owning plenty of cultural historical and natural attractions, iran has not reached to a proper position in this field. besides, the historical cities of a country are considered as the income resource and national wealth of it. qazvin with a rich cultural precedent, have suitable ...
to study the effect of sowing date and a single irrigation (si) on yield and yield components of barley, a field experiment was conducted in dryland agricultural research institute (maragheh, iran) in 2004-06 cropping seasons, using a split plot based on a randomized complete block design with 3 replications. main plots were assigned to 3 levels of sowing date (early, normal and late). sub-plot...
به منظور بررسی تاثیر رژیم های مختلف آبیاری بر عملکرد و اجزای عملکرد ارقام سورگوم، این تحقیق در سال زراعی 1390 در مزرعه تحقیقاتی دانشگاه شهید باهنر کرمان بصورت کرت های خرد شده در قالب طرح بلوک های کامل تصادفی و در سه تکرار اجرا گردید.کرت های اصلی شامل سه رژیم آبیاری به ترتیب آبیاری پس از 50،80 و 110 میلی متر تبخیر از تشت تبخیر کلاس a در نظر گرفته شد. کرت های فرعی مشتمل بر پنج رقم سورگوم به نام...

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...
