In order to evaluate the effect of plant growth-promoting rhizobacteria) PGPR( on salt tolerance in vegetative and reproductive growth stages of safflower (Carthamus tinctorius), a randomized complete block design with a factorial combination of bacterial inoculation and salinity, each in three levels, and four replications was conducted in experimental glasshouse of Vali-e-Asr University of Ra...

In order to find suitable cultivar and N-topdress rates in corn planted after wheat harvest, a field experiment was conducted in Isfahan University of Technology Experiment Farm located at Shervedan, Falavarjan in 1994. The experiment design was a split plot with a randomized complete block arrangement and four replications. Main plots were four N-topdress rates (0, 90, 180, and 270 kg/ha) and ...

  An experiment was conducted to investigate the heterosis in 12 F1 hybrids of durum wheat using agronomic and morphological traits. Parents were selected according to the estimated genetic distances based on the results of a two-year field experiment, which were then crossed to produce F1 hybrids. Twenty-three genotypes (including 11 parents and 12 hybrids) were evaluated using a randomized co...

Performance of any breeding program is mainly due to the correlation among yield and relative importance of each component. This study was conducted to analysis the correlation among grain yield and some important traits in seventhin spring canola (Brassica napus L.) cultivars at the farm in safiabad, from 2014 to 2015. A randomized complete blocks design with four replications was used. The an...

In order to determine the optimal rates of Pertilachlor and Sunrice­-plus herbicides for weed control of rice (Oryza sativa Var.Tarom Hashemi), a factorial experiment was conducted with a randomized complete block design with four replications in Rice Research Farm of Faculty of Agriculture, University of Guilan, Rasht, northern Iran. The first factor was weed control treatment which   consiste...
