Abstract

Biocompost was formed from press mud cake (PMC), flyash, Eichhornia crassipes and spent wash by bioinoculant Trichoderma viride in treatments viz. PTDE, T₁, T₂, T₃ and T₄. Variations in temperature, pH and NPK of compost were also analysed. Biocompost maturity was evaluated by C/N ratio on 8^th, 16^th, 24^th and 32^nd days. It was observed that Trichoderma growth is higher at pH 6.5 that hastened the decomposition process and improved the quality of compost. Immature and mature compost were evaluated by C:N. Seeds of Phaseolus aureus Roxb. cv. K-851 were sown in polybag culture (5 kg soil + 159 g compost) @ 5 qt/acre or @ 12.50 kg/hac during July 2004, 05, 06, and 07. The results revealed significantly higher germination %, Vigour index, length of ischolar_main and shoot, chlorophyll content, biological yield and harvest index. Bioinoculant decomposes the substrates early in T₄ treatment and showed enhanced growth and yield due to mineralized nutrient status of compost.
