dc.description.abstractIn situ cultivation and incorporation of green manure legumes in coconut basins improved the microbial activity in the root region of coconut in a slightly acidic laterite soil. Populations of bacteria, fungi, actionomyoetes, asymbiotic nitrogen fixing and phosphate solubilising bacteria were significantly increased during the maximum vegetative phase and at 30 days of incorporation of green manures. However, such a proliferation in microflora was not observed at 60 days of incorporation. Dehydrogenase activity also exhibited a similar trend, whereas the activity of urease enzyme did not increase to any significant level. The number of endomycorrhizal chlamydospores in the root region soil and the intensity of mycorrhizal infection in roots of coconut were high in green manured basins. In general, Pueraria phaseoloides had a better beneficial influence on microbial characteristics of coconut root region as compared to Mimosa invisa and Calopogonium mucunoides.en_US
