abstract chickpea is weak in competition of weeds that damages to it at between 40 t0 60 percent. kermanshah province is one of the most important region for chickpea fields in iran. for these reosons, weed management is necessary in this crop. in order to evaluate of herbicides and stubble control on broad leave weeds control in chickpea. experiment was conducted in agricultural research stat...

  Application of selection index for screening desired plants based on complex quantitative traits can be more effective than direct selection. This study was conducted using an F2 rice population consisting of 87 plants derived from a cross between two cultivars Gharib and IR28. The purpose was to establish suitable selection indices for increasing yield and its related traits in research farm...

To evaluate effect of different irrigation regimes and mycorrhizal fungi on the growth and yield of mungbean NM92 [Vigna radiata (L.) Wilczk], a field experiment was conducted in split plot arrangements using randomized complete block design (Irrigation after 50, 100, 150 and 200 mm evaporation from pan class A as main plots and mycorrhiza species, Glomus mosseae, G. intraradices and a non-inoc...

     Determining the relationships between grain yield and some yield components of wheat is most important in permanent yield production.  Using path coefficient analysis in order to determine key traits affecting majorly yield, and also to study direct and indirect effects of yield and yield components, this research was performed during 2006-2009 ys using 94 doubled-haploid (DH) lines, their...

To investigate the effect of nitrogen and zinc elements on the quantity and quality characters of sunflower plants (Jamah1cultivar), a factorial experiment in a randomized complete block design with three replications was conducted at the University of Zabol, Zabol, Iran in 2013. The experiment consisted of three nitrogen levels: 100, 200 and 300 kg ha-1 as the first factor and three levels of ...

This research was carried out in a factorial split plot experiment based on a randomized complete block design with four replications in Semnan Agriculture Research Center, Bastam, central Iran, in 2019. Experimental treatments included irrigation as the main factor at three levels of 100, 75 and 50% of water requirement and sub-factors including cultivar at three levels (Titicaca, Q26 and Q29)...
