In order to optimized nitrogen fertilizer recommendation for a new safflower cultivar called “Padideh” an experiment was conducted in two regions of East Azerbaijan, Tikmehdash and Shabestar. Experimental design was a randomized complete blocks design arranged in factorial with three replications. The first factor was different nitrogen rates including 30, 60, 120 and 180 kg ha-1 nitrogen suppl...

The increase in the cost of fertilizers and their low efficiency has led, through nanotechnology, to generation new innovative products that are sustainable improve productivity crops. Therefore, objective present study was evaluate efficacy a molybdenum nanofertilizer compared two conventional (chelate sodium molybdate) applied via foliar combined with soil fertilization NH4NO3 relation Nitrog...

Canola sensitivity to delayed sowing date should be managed in such a way that the observance of crop rotation with less reduced in seed yield. The research was conducted to evaluate the yield variation of Hyola401 hybrid, affected by sowing date and nitrogen fertilizer treatments. In this study, the effect of planting date and different levels of nitrogen fertilizers on effective characteristi...
