Effect of Intercropping and Fertilizer Type on Growth and Yield of Soybean (Glycine max L. Merrill)

P. Wandahwa, I.M. Tabu, M.K. Kendagor and J.A. Rota
Studies were conducted at the Kenya Agricultural Research Institute in 2002 to determine the effect of intercropping and fertilizer type on the growth and yield of soybeans. The treatments included cropping system (sole and intercropped soybean with maize), varieties (non-herbaceous and herbaceous) and fertilizer type (organic and inorganic). The experiment was laid out as split-split plot in a randomized complete block design with three replications. Cropping system formed the main plots, the varieties sub-plots and fertilizer the sub-subplots. Results showed a significant variety by cropping system interaction. Non herbaceous variety yielded significantly higher than herbaceous when intercropped, while herbaceous yielded significantly higher as a sole crop. Inorganic fertilizer significantly depressed the growth and yield of soybean in season II because of the salt effect on plant germination. To improve soybean production, account should be taken of variety morphological characteristics, cropping system and initial fertilizer type during a particular season.
