An experiment was conducted during the winter (rabl) seasons of 1997-98 and 1998-99 to study the effect of fertilizer levels and seed rates on growth and yield of surface-seeded wheat (Triticum aestivum L. emend. Fiori Pao!.) under lowland rice ecosystem of north Bihar. Application of 150, 75 and 50 kg N, P and K/ha recorded significantly higher values of yield-attributingcharaCters, grain and straw yield, net return and NPK uptake by the crop than the lower levels of fertilizer but net return/rupee of investment and protein content in grains increased significantly only up to 120, 60 and 40 kg N, P and K/ha. Among the seed rates, 175 kg seed/ha resulted maximum number of ears/m2, grain and straw yield, net return, net return/rupee of investment and NPK uptake than 150 and 125 kg/ha seed rates. Protein content in grains was unaffected by seed rates. Application of 150, 75 and 50 kg N, P and K/ha together with 175 kg seed/ha was found to be the best for obtaining higher grain yield of surface-seeded wheat.
