Laboratory and pot experiments were conducted to vatuate the effectiveness of organic matter in combination with urea under surface and subsurface condition on rice yield production. Results revealed that application of organic matter decreased the volatilization of ammonia. Subsurface tonditjon was more effective in reducing N-Ioss than surface one. It was noticed that O.M. addition stimulate the grain yield for both surface and subsurface circumstances. Maximum yield was obtained at equal rate of N from inorganic and organic sources. Data also indicated that surface application gave higher grain/straw ratio as coTpared to the surface one. Application of organic matter increased the nitrogen content in nee grain as compared with urea alone. Increasing ratios between organic tter and urea gradually inaeased the N-CQntent in rice grain.
Deep placement of urea combined with organic matter increased P and K content for both grain and straw as compered with surface applicatlo . The highest vaiuei uf :h; resi<ll}~I-N ~~~ 9P"rved at equal doses of urea nitroge~ an~~an!c matter. Deep placement was better than surface application on the residual nitrogen, content in soil. .
