Ecotechnology of Compost from Biodegradables Inoculated By Trichoderma and Its Effects On Growth Of Medicinal Plant Ocimum gratissimum L.

Abstract

Microbiological applications of industrial waste (PMC & DSW) and aquatic weed (Azolla) into compost inoculated by Trichoderma viride in T1 (PMC+Azolla+Water), T2 (PMC+Azolla+DSW) T3 (PMC+Azolla+DSW+Trichoderma) than control have been investigated.

PMC distillery spent wash and Azolla were mixed and inoculated by Trichoderma and observed microbial succession during decomposition. Variations of temperature pH, EC, OC, NPK, have been observed on 8^th, 16^th, 24^th 32^nd day and compost maturity was evaluated by odour, appearance, moisture content, dipping in water and C/N ratio. Temperature based phases (Psychrophilic, Mesophilic, Thermophilic, Stablization & Poikilothermic) were observed on 32^nd day during composting. Trichoderma hasten the decomposition process and improved the quality of biocompost. Seeds of ocimum gratisimum, medicinal herb, were sown in patriplates with compost extract and polybag culture with 5 kg soil +159 gm biocompost @ 125kg / hec during 2006, 07, 08, 09. The results were discussed that germination %, GRI, growth index of root and shoot, phytomoss were significantly increase in compost extract and compost treated soil than control.
