Effect of Fertilizer and Rhizobium Inoculation on Growth and Yield of Soyabean Variety (Glycine max L. Merrill)

Adeyeye AS, Togun AO, Olaniyan AB and Akanbi WB

The study assessed the response of three soybean varieties: (TGX 1740 - 2F, TGX 1842 - IE, and TGX 1448- 2E) to three fertilizer treatments (4 t/ha compost, 30 kgN/ha urea, 2 t/ha compost+30 kgN/ha urea and a control) with or without Rhizobium Inoculation using strain R.25B+2180A. The experiment was a randomized complete block design with three replications. Data collected on vegetative, reproductive and grain yield parameters were subjected to analysis of variance ANOVA at 5% probability level. Fertilizer effects were significant on all the parameters assessed. In this study, soybean grain yield varies from 0.2 t/ha in plants nourished with 30 kgN/ha to 0.96 t/ha in plants that received 4 t/ha compost. Inoculation of soybean seed with rhizobium significantly improved the grain yield of soybean. Inoculated plants produced grain yield that is 35% higher than non-inoculated ones. The interactive effect of fertilizer types and inoculation was not significant on soybean grain yield and yield parameters. It was concluded that the use of 4 t/ha compost in combination with appropriate rhizobium strain could be a good agronomic practice for the production of high quality grain in soybean.
