DECOMPOSITION OF AGROINDUSTRIAL WASTES AND ITS IMPACT ON GROWTH AND YIELD PARAMETER OF VIGNA RADIATA L. (MOONG BEAN)

摘要

Microbial technology for early decomposition of compost was formed from PMC, flyash, distillery spent wash (D.S.W.) and chopped water hyacinth by bioinoculant Trichoderma viride in different treatments-PTDE, T_1, T_2, T_3 and T_4 over control were investigated. The compost samples were analyzed for pH, E.C., moisture content, organic carbon and nitrogen. DSW addition in three splits (0-18-16 day) was done to maintain the moisture control and aeration. Its maturity evaluation by C/N ratio. Seeds of Vigna radiata L. cv. K-851 were sown in pot culture with (159 gm compost + 5 kg soil) @ 5 qt/acre. The results revealed that the seed germination, vigour index (VI), plant height, phytomass, no. of seeds, seed yield, 100 seed weight, biological yield and harvest index were significantly increased in T_4 compost treated soil than control. The T_4 treatment early decomposed by a fungus (Trichoderma viride) and showed enhanced growth and yield due to mineralized nutrient status of compost.
