Abstract:

Results of the field experiment entitled Effect of vermicompost and phosphorus on performance of greengram [ Vigna radiata (L.) Wilczek] grown under loamy sand soil the treatment comprising four levels of vermicompost (0, 1, 2, and 3 t ha -1 ) and four level of phosphorus (0, 10, 20, and 30 kg ha -1 ) making 16 treatment combinations were laid out in factorial randomized block design with three replication. Green gram also known as mung bean is a self pollinated leguminous crop which is grown during kharif as well as summer seasons in arid and semi-arid regions of India. It is tolerant to drought and can be grown successfully on drained loamy to sandy loam soil in areas of erratic rainfall. The centre of origin of mung bean is India occupies 3.4 million hectare areas and contributes 1.4 million tons in pulse production in the country. Result shows that application of vermicompost at the rate of 2 t ha -1 significantly increased the total, effective, fresh and dry weight of root nodules per plant leaf area index leghaemoglobin content in root nodules at pre-flowering stag, number of branches per plant, plant height number of pod per plant, number of seed per pod, test weight, seed and straw yield, N, P, K and S uptake by seed and straw and an available N, P, K and S content in soil at harvest and net returns over preceding levels of vermicompost. However N, P, K and S uptake by seed and straw and organic carbon content in soil at harvest increase significantly with an increase in each level of applied vermicompost upto 20 t ha -1 vermicompost. Result further indicates that total, effective, fresh and dry weight of root nodules per plant leaf area index leghaemoglobin content in root nodules at pre-flowering stag, number of branches per plant, plant height number of pod per plant, number of seed per pod, test weight ,seed and straw yield, P content in seed and straw, N, P, K and S uptake by seed and straw and an available P content in soil net returns increase significantly with increasing levels of application phosphorus up to 30 kg ha -1 over lower levels. However plant height chlorophyll content in levels N, K and S concentration in seed and straw and available N
