The study attempted using single, dual and triple inoculant treatments on windrow composting of pressmud treatment (T7) performed better in exhibiting better extracellular enzyme complexes such as cellulose, pectinases and xylanases compared to dual and single and there by exerting early maturity of the pressmud compost within 45 days. Changes in pH, EC and C:N ratio, were determined during windrow composting of pressmud sprayed 90 day. The triple inoculant treatment attained its stability in pH 7.1, EC 2.9dsm-1 and C:N ratio 21:1 with in 45days. Whereas dual required an addition of 15 days and single required an addition of 30 days. The mesophilic and thermophilic microbial inoculants in triple inoculant mixer were steadily found throughout the period of composting enabling an efficient extracellular enzyme complex.
