Prakash 1200541Two field experiments were conducted in the experimental farm, Department of Agronomy, Annamalai University, Annamalai Nagar, India on clay loam soils during Samba (August-January) 1998-99 and Kuruvai (July-October) 1999 seasons to study the impact of integrated nutrient management practices on the growth and grain yield of rice. The experiments were laid out in split plot design with three replications. Main plot consisted of nine different nutrient source combinations whereas; in sub plot seed treatments were taken. The experimental results revealed that enriched FYM+neem cake blended urea +K in combination with seed soaking of Penshibao and Azospirillum produced taller plants, increased number of tillers m-2, higher leaf area index and maximum dry matter production as compared to all other treatment combinations. Increased growth parameters also favorably increased the grain and straw yield of rice. Magnitude of increase of grain yield was 29.0 and 34.6% during Samba and Kuruvai seasons, respectively over control (Conventional NPK+water soaking).]]>De Datta, S.K.,198622417426Singh, D.P. and P.K.
