drought stress is one of the important environmental factors reducing grain yield of plants in arid and semiarid regions. study the effect of water deficit stress on yield, water use efficiency and harvest index of sesame varieties, this experiment was conducted as a split plot based on a randomized complete block design with three replications, at agriculture and natural resources research cen...

The present study evaluated the effects of different dosages herbicides Oxyfluorfen and Trifluralin on crop properties of garlic, including plant height, number of cloves per bulbs as well as economical and biological yield of garlic. In this research, a randomized complete block design, with seven treatments and three replications, along with a control sample (weeding and no weed control), was...

According to urgent need of corn to nitrogen and since this element play a main role in improving of yield corn, thus, in order to investigate the effect of different levels of urea on yield and yield components of corn 704, an experiment was conducted randomized block with three replications in cropping year of 2012. Experimental treatments included six levels of urea (0, 30, 60, 90, 120 and 1...

This research set out to evaluate the effect of combined biological and chemical nitrogen fertilizers on some corn hybrids. To this end an experiment was conducted as split plot on the basis of randomized complete block design with four replications. Main plots were included: use of chemical and biological fertilizers in four levels: 100% chemical fertilizer, 75% chemical fertilizer + 100% bio-...
