Description
Two-year field study was conducted to determine the yield advantage in maize-bean intercrop system at a certain plant population pressure. Maize cultivar 'Wasehomare' was intercropped with bean cultivar 'Top Crop' in the replacement series treatments with each sole crop in 1983 and 1984. Fresh grain weight of maize and fresh pod weight of bean were analysed statistically. Grain weight per plant was increased significantly in some intercrop treatments in both years. Pod weight per plant was slightly increased by intercropping in only 1983. Competitive ability of maize was dominant in many intercrop treatments in both years. To assess yield advantage in intercropping, Land Equivalent Ratio (LER) was computed. LER values varied from 0.983 to 1.390, which tended to increase with increase of the number of maize plants within a plot. But the maximum advantage was achieved in this treatment, where both component crops showed cooperative increases of their yields than those expected from each sole crop. It was found that there are favorable propotions in the replacement series treatments to achieve higher yield advantages, but the best treatment cannot be specified.
