Abstract:

Green manure increased the organic matter content of the soil. Soybeans, a green manure. provided the highest organic matter content (3.7960/o), followed by mungbean (3.2680'/o) and bushbean (2.836%). The plot without green manure bad the lowest organic matter content of 1.7400'/o. The nutrient from the organic matter of the oil significantly increased plant height in the treated plots more than those in plot without green manure. This practice was not effective in increasing the panicle length, panicle weight, and the 100-grain weight of sorghum. Using mungbean as green manure significantly decreased the grain yield of sorghum although there was a significant increase in plant height. Highly significant differences were observed on the effects of the inorganic fertilizer treatments. Application of 30-30-30 kg/ha of N, P20s, and K20 markedly increased plant height, leaf area index, panicle length, panicle weight, and grain yield (2.24 t/ha). Plots where no fertilizer was applied yielded 1.12 t/ha of grain.
