Treatments; F1 is showing low nitrogen application rate 120 kg ha−1, F2 is showing high nitrogen application rate 180 kg ha−1, LD is showing low planting density (8 plants m−2), MD is showing medium plant density (10 plants m−2) and HD is showing high planting density (12 plants m−2). Seedling stage was at 20 DAE, Squaring stage was at 50 DAE, Blooming stage was at 80 DAE and Maturity stage was at 120 DAE. Mean values followed by the same letters are not significantly different using least significance difference test (LSD) at 0.05 probability level.
