The growth and yield development of soybean (glycine max (l) merill) variety as affected by fertilizer application

Abstract: 

The study was designed to evaluate the impact of different fertilizer on the growth and yield of soybean varieties at Babcock university farm, Ilishan-Remo in 2009 and 2010. The experimental design was a randomized complete block (RCBD) using three replications. The treatments are three varieties of soybean: (TGx 1740-2F), (TGx 1842 - IE) and (TGx 1448 -2E) and four different fertilizers application: 4ton/ha compost; 30kgN/ha, urea, combination of 2ton/ha compost and 30kgN/ha urea, and (a control). Data analysis using ANOVA at 5% level of probability showed Plant height, number of leaves, number of nodes and branches were significantly higher in fertilizer plots than in the control (P < 0.05). However at 8, 10 and 12 weeks after planting, plant height was significantly influenced by both application of 2t/ha compost + 30kgN/ha urea and 4t/ha compost which was superior to other fertilizer treatments and the control. Number of leaves showed the similar trend where compost rate of 4t/ha was superior at all stages of growth measured. At 12 weeks after planting, TGx 1842 – IE had significantly higher plant height compared with the other varieties study. Application of compost at the rate of 4t/ha produced significantly higher number of seeds per plant followed by combine application of 2t/ha compost + 30kgN/ha and the least from the control plots.
