Impact of Plant Population on Seed Yield of Water Stressed Soybean (Glycine max L) at HalfaElgadidah
Journal Title: Haya: The Saudi Journal of Life Sciences - Year 2017, Vol 2, Issue 9
Abstract
Abstract:In order to evaluate the impact of plant population on stressed soybean clycine max (L.), a field experiment with 3 different plant populations (at three different irrigation regimes was carried out. Plants were grown under frequent irrigation (W1), moderate and severe drought stress (W2 and W3). The different plant population designated as D1, D2 and D3, corresponding to spacing between plants of 5, 10 and 15 cm. Seed yield components(number of fruiting branches, pods, seeds weight per plant , seed yield per unit area and measured related characters decreased from normal irrigation regime to water deficit stress in both seasons. Also, the same trend was observed due to increasing spacing between plants particularly under stress conditions. Based on results, soybean yield and yield components decreased when that drought stress occurred. Withholding irrigation reduced seed yield by more than 50% in stressed soybean plants compared with normal irrigated plants. Keywords:Soybean, Water stress, plant population, Yield and Yield components.
