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 8th, 16th, 24th and 32nd 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.
