A field experiments was conducted for three consecutive years (2000-2003) at the agriculture form of Sheila Sheila Dhar Institute of Soil Science, Allahabad with an objective to study the preparation of phospho-compost and its effect on productivity of rice-wheat cropping system. The prepared phosphorus enriched compost and ordinary compost were analyzed for C, N, C: N, total phosphorus, water soluble phosphorus, citrate soluble phosphorus besides major and micronutrient content. The phosphor-compost was found to be superior to FYM, ordinary compost in terms of organic carbon and total and N, Ca, Mg, K, Fe, Mn, Zn, and Cu content, and can supplement single super phosphate in field trial with rice and wheat crop. The application of phospho-compost for supplementing inorganic P source and part of N and K was found to be effective and recorded comparable result in rice and wheat crop for plant population, grain yield, protein per cent, N and P content in crop plant and available nutrients and their balances in soil after harvesting.
