Abstract

A split plot factorial experiment based on randomized complete block design, with three replications was conducted to study the effects of four irrigation regimes (I1, h2, h3 and I4: irrigating plants after 40, 60, 80 and 100mm evaporation from CLASS A PAN, respectively) and four plant densities (D1=30, D2=40, D3=50 and D4=60 Plants/m2) on vegetative and reproductive characteristics and seed yield of three SOYBEAN CULTIVARS (V1= Habit, V2= Williams and V3=Hill) for two years (200 I and 2002). Irrigation treatments were assigned to the main plots, and plant densities and cultivars to the sub-plots. The results showed that the highest and lowest seed yields were produced by h and 4 treatments, respectively. It was also revealed that the highest seed yield was produced by V2 with PLANT DENSITY of D3, and lowest by V3 with D1 PLANT DENSITY. Highest growth of vegetative and reproductive characteristics was also due to I2 irrigation regime. Lower plant densities decreased seed yields of single plants, while it increased the yield per unit area. Vegetative and reproductive growth of most of the single plants characteristics decreased by higher plant populations per unit area. Varietal responses to different plant populations were different in such a way that V1, V2 and V3 produced highest seed yields with 60 plants/m2 (D4), 50 plants/m2 (D3) and 40 plants/m2 (D2) respectively.
