Abstract

Water deficit affects plant physiology, morphology and metabolism. In order to evaluating the effects of NITROGEN on the yield and its components in water deficit conditions, an experiment was conducted as a factorial experiment with randomized complete block design. The main plots were irrigation regimens with 7, 14,21 days interval and the amount of NITROGEN application as equivalent 30,60,90,120 kg of NITROGEN and the sampling times (49, 59, 69, 79, and 89 days after sowing) were subplots. The STRESS OF WATER DEFICIT reduced the yield of SOYBEAN through reducing the number of pods in each plant as well as the grain weight of the SOYBEANs. However, the application of NITROGEN led to a reduction in the adverse effects of water deficit, with increase in the application to as much as 90 kg pure NITROGEN per hectare resulting in a significant increase in the yield of SOYBEANs as evidenced through the increase in the number of pods per plant as well as the grain weight of SOYBEANs in all levels of irrigation conditions. Corresponding to an increase in the amount of NITROGEN applied from 30 to 90 kg per hectare, increases yield of 53%, 84% and 54%, respectively in 7, 14 and 21 days irrigation intervals.
