A field experiment was conducted with three integrated nutrient management practices and three spacings were laid out in Factorial
Randomized Complete Block Design with three replications during Kharif 2009 at College of Agriculture, Shimoga. The integrated nutrient
management practices including 50% RDN through chemical fertilizers and 50% RDN through organic sources like farm yard manure, poultry
manure and vermicompost with three spacing viz., 30 x 30 cm, 20 x 20 cm and 20 x 10 cm. Among integrated nutrient management practices
(M3) 50% RDN through chemical fertilizers + 50% RDN through vermicompost recorded significantly higher plant height (80.54 cm), leaf area
(1537.69 cm2), number of tillers hill-1(30.04), total dry matter accumulation hill-1 (84.78 g) grain yield (39.48 q ha-1) and straw yield (52.9 q ha-1).
Wider spacing of 30 x 30 cm (S3) had registered significantly higher plant height (84.26 cm), leaf area (1538.12 cm2) number of tillers hill-1
(33.32), total dry matter accumulation hill-1 (87.18 g), grain yield (40.61 q ha-1) and straw yield (53.63 q ha-1).
