Abstract :
To study the effect of irrigation and plant density on mungbean (Vigna radiata L.) an experiment was carried out as split plots in a randomized complete block design with three replications in Shush region during 2019. In this study, the main factor with four levels of irrigation (irrigation after 60, 80, 100 and 120 mm evaporation from pan class A) and density as the subplot levels (5, 10 and 15 cm between plants within the row) has been considered. The test results showed that all studied characters were affected significantly by irrigation regime and sowing density. In this study the most number of pod, number of seed in pod, seed yield, biological yield and harvest index were achieved in 60 mm irrigation regime and with increasing period of irrigation, this characters were decreased, as seed yield decreased when elongated irrigation period from 60 mm to 80, 100 and 120 mm as arrangement: 5.27, 13.26 and 26.99%. Also in this study 5cm sowing density were obtained the most 1000 seed weight, seed yield and biological yield. In this study, increasing seed yield in 5 cm sowing distance was 6.94 and 20.51%, in compare with 10 and 15 cm as arrangement. However, increasing period of irrigation induced low consumption of water, as: 25- 100%.
