In order to investigate the effect of super absorbent polymer and manure fertilizer on water use efficiency of wheat (Triticum aestivum L.) cultivars under different water deficit conditions, an experimental was carried out in a factorial layout based on randomized complete block design with three replications at the research field of West-Azerbaijan (Saatlo station) during 2017-2018 cropping seasons. The first factor was irrigation in two levels: normal and drought stress conditions. The second factor was super absorbent polymer 200 kg ha-1, manure fertilizer 40 ton ha-1, dual their application and control (non-application fertilizer) and the third factor included wheat cultivars (Mihan, Heidari and Zarineh). The results indicated that drought stress compared to normal irrigation reduced grain yield, chlorophyll index, harvest index and relative water content about 32, 22, 24 and 19 percent, respectively. The highest leaf temperature (33.10 °C) was obtained under drought stress and non-application fertilizer application and the lowest leaf temperature (21.99 °C) under favorable irrigation conditions and dual application of super absorbent polymer and manure fertilizer. The highest economical water use efficiency (1.34 kg m-3) and biological water use efficiency (4.10 kg m-3) were observed under drought stress conditions and dual application of super absorbent polymer and manure fertilizer. Mihan was superior cultivar for grain yield, harvest index and relative water content among cultivars under two different moisture conditions. The highest grain and biological yields were obtained under favorable irrigation conditions and dual application of super absorbent polymer and manure fertilizer.

Delay in planting and low precipitation in wheat (Triticum aestivum L.) farming is the problem in Western Azerbaijan province - Iran. In order to evaluate the effects of seed priming an experiment was conducted under laboratory, green house and field conditions in 2006-7. The experiment was arranged as a factorial in which first factor included of four cultivars (Zarrin, Shahriar, Sardary and Azar) and second factor was including the distilled water, 10% polyethylene glycol (8000), 2.5% KCl, 10% Urea, 4% Micro nutrient, 1000ppm Cycocel (CCC), 20ppm Auxin (IAA) and non priming treatment as control. The maximum water absorbed was for Shahriar with distilled water. IAA and CCC treatments increased seed weight. Analysis of variance showed that the lengths and dry weights of plumule and radical, chlorophyll content, absorbed nitrogen, grain yield and its components, total dry matter and plant height were significantly different (P? 0.05). All of priming treatments had more absorbed nitrogen, grain yield and its components than control. CCC treatment had the highest value of lengths and dry weights for plumule and radical, grain yield, but the lowest value of plant height. In contrast urea had the negative effects for seedling related traits.
