Abstract: The aim of the present study was to assess the effects of inoculation of Trichoderma harzianum, Eisenia fetida and cow dung on the physicochemical quality of paddy straw composting which was carried out for 90 days. The different treatment groups were Paddy straw (T0 ), Paddy straw + Cow dung (T1 ), Paddy straw + Cow dung + Eisenia fetida (T2 ), Paddy straw + Cow dung + Trichoderma harzianum (T3 ), Paddy straw + Cow dung + Eisenia fetida + Trichoderma harzianum (T4 ). The ratio of cow dung and paddy straw was 2:1. Among all treatments, T4 was identified as the best treatment for decomposing the paddy straw as it recovered the nutrients within the recommended levels of a high quality product. The consortium of Trichoderma harzianum, Eisenia fetida and cow dung lowered the total organic carbon (TOC) and C:N ratio by 28.8% and 33.1%, respectively, at pH 6.5. The increase in N (0.87%), P (0.47%), K (2.66%), Ca (0.033%), Mg (0.056%) and Na (0.42%) was significant in T4 treatment. The micronutrients, namely Cu (47.9 ppm), Fe (1128 ppm) and Zn (500 ppm), also showed a significant increase in this treatment, i.e., T4 . Therefore, results suggested that combinatorial composting by Trichoderma harzianum, Eisenia fetida and cow dung is quite promising in the decomposition of paddy straw to obtain quality compost in a short time. Furthermore, this study will help in the sustainable management of paddy straw with concomitant reduction inenvironmental pollution caused by the open burning of paddy straw.
