Among the crop residues used for preparation of compost, wheat straw (WS) + urea (1.5 - 4.5 per cent) + rock phosphate (RP) (6 - 12 per cent) + Sulphur (S) (1 to 3% through gypsum) and shredded cotton stalk (SCS) + urea (1.5 - 4.5%) + RP (6 – 12%) + S (1 to 3% through gypsum) were found equally beneficial in improving the quality of compost. The pH of compost rises initially and further drop at the maturity of compost. Composting with different sources of nutrient increased the concentration of total nitrogen, phosphorous, Citrate soluble and water soluble phosphorous, potassium, Sulphur and micronutrients concentration with the increased in the levels of gypsum and RP. Organic carbon, microbial respirations and Carbon:Nitrogen ratio (C:N) decreased with the advancement decomposition progressed. The microbial count (viz. bacteria, fungi and actinomycetes) swiftly rise initially during first 60 to 70 days and thereafter decreased.
