Abundance, frequency and occurrence based comparison between mycoflora involved in the decomposition of Sesbania aculeata L. under experimental and natural conditions

Green manuring is a cost-effective technology to sustain soil fertility and enhance activities of soil micro-flora and micro-fauna. The comparison between mycoflora associated with the decomposition of Sesbania aculeata L. green manure under nylon net bag and mycoflora inhabiting soil mixed green manure at experimental site was investigated. During the study abundance, frequency and occurrence of both type of mycoflora was investigated. Maximum moisture content was recorded in the month of July and thereafter it decreased. The average number of fungi involved in the decomposition of Sesbania aculeata L. was found to be dependent on physical climate viz., moisture content, rainfall, temperature and relative humidity. The highest occurrence of mycoflora in experimental condition (48.95×104 per g green manure) and natural condition (47.85×104 per g green manure) was found in the month of July, whereas in the month of June lowest occurrence of mycoflora in both conditions was recorded. The number of fungi slightly decreased in August and thereafter declined gradually up to December. From the above finding, pattern of fungal succession on decomposing green manure was deciphered that may enable rapid decomposition of agricultural wastes.
