Description A field experiment was conducted during November 1994-October 1999 at Central Potato Research Station, Patna, to develop nutrient management schdule through fertilizers and farmyard manure for potato (Solanum tuberosum L.)-onion (Allium cepa L.)-rice (Oryza sativa L.) ratation. Varying levels of nitrogen, phosphorus and potassium fertilizers at 0, 50, 100 and 150% of hte recommended rate in 9 treatment combinations were laid out on a permanent site. The application of 30 tonnes/ha of farmyard manure and zinc sulphate @ 25 kg/ha to potato were also included in some of hte treatments. Potato and onion were responsice to N, P and K, while rice responded to only N and K. The potato required NPK at 150% of the currently recommended rate, ie 240 kg N, 52 kg P and 150 kg K/ha, onion crop grown after potato at 150% recommended NPK levels required the currently recommended rate of NPK, ie 100 kg N, 22 kg P and 67 kg/ha while the rice required the currently recommended rate of N and K, ie 120 kg N, and 33 kg K/ha, but not P. The farmyard manure applied at 30 tonnes/ha along with 160 kg inorganic N;/ha (FYM+N) to potato crop was as effective as 150% of currently recommended NPK rate. Zink neither had direct effect on potato nor any residual effect on the succeeding crops of onion and rice Integrated use of farmyard manure and nitrogen also helped in minimizing the yield decline with time and maintained the crop productivity at a higher lever than the use of fertilizerS alone. Higher net return (Rs 64 046) and higher benefit: cost ratio (2.03) was recorded in potato-anion-rice sequence when 30 tonnes/ha farmyard manure was integrated with 160 kg N/ha in potato. Application of farmyard manure for 5 years improved the organic carbon status of the soil by 20% and countered the acidification effect of urea. There was a slight improvement in P availability (6 kg/ha) of soil, but none of the treatments could maintain K availability of the soil at the initial level.
