Abstract: 

Experiment was conducted in plot No. 126 of E block, Main Agricultural Research Station (MARS), University of Agricultural Sciences, Dharwad during kharif, 2011. The geographical co-ordinates of the experimental site are 15026' N latitude and 75007'E longitude and an altitude of 678 m above mean sea level (MSL). Grain yield was significantly influenced by the application of organic and inorganic sources of nutrients. The highest grain yield of 4.46 t/ha was recorded in the treatment with RDF + PM and was on par with the treatments T2 (4.25 t/ha), T1 (4.05 t/ha) and T4 but differed significantly to other treatments. Higher stover yield was (5.86 t/ha) recorded in the treatment RDF + PM and it was significantly superior to all other treatments but was on par with the treatments RDF + VC (5.63 t/ha), RDF + FYM (5.42 t/ha). Significantly higher uptake of nitrogen was recorded in the treatment with the application of RDF + PM (121.5 kg/ha) and it was on par with the treatment RDF + VC (111.1 kg/ha) but differed significantly to all other treatments.
