In order to investigate the appropriate combination of chemical and bio-fertilizers and their effectiveness on corn seed yield while defoliating the upper leaves of the ear, a randomized complete block design experiment with four replications. Fertilizer treatments were applied at four levels including 100% urea, 75% urea + 100% Nitroxin, 50% urea + 100% Nitroxin, 25% urea + 100% Nitroxin. In h...

Despite its economic importance, not much information exists on growth and productivity of durum wheat in Iran and Isfahan. In order to evaluate growth, grain yield, and attributes in three durum wheat genotypes, Osta/Gata, Dipper-6, and PI40100, with five planting densities of 200, 275, 350, 425 and 500 seeds/m2, a four-replicate RCBD field study with a spilt-plot layout was carried out in win...

In order to study the effect of on-farm seed priming using tap water and zinc sulfate solution with 0.03% zinc on yield and yield components of two intermediate maturing maize cultivars, a factorial experiment was carried out in complete randomized block design with three replications in Research Farm of Bu Ali University, Hamedan, Iran in 2011. Seed priming consisted of three levels (priming w...

Abstract Introduction Characterization of physical and chemical soil criteria is a key step in understanding the source of spatial variability in the productivity across agricultural fields (21). Crop yield variability can be caused by many factors, including spatial variability of soil texture, crop management, soil physical and chemical properties and nutrient availability (45). Understandin...

The research on reducing the water consumption in conventional cropping system is one of the important strategies to improve the water use efficiency in agriculture. In order to investigate the effect of time of potassium application under different irrigation regimes on millet grain yield and protein percent, a field experiment was carried out in Agricultural Research Center of Yasuj, Iran, in...

The experiment was completed to evaluate the responses of forage yield and silage quality of dual-purpose corn hybrids to urea fertigation. For this purpose, two studies were conducted each as a split plot experiment based on a randomized complete block design with three replications at two locations in research farms of College of Agriculture, Isfahan University of Technology, Isfahan, Iran, i...
