Variation in growth rate and seed yield of Brassica juncea genotypes as affected by nitrogen levels
Crop growth rate (CGR) increased rapidly upto 60-90 DAS and suddenly declined thereafter, whereas, relative growth rate(RGR) was maximum at initial growth stage and declined later on throughout the growth period. CGR was better in RH-9707 and RGR in RH-9510. At initial stages, with the application of nitrogen, CGR increased significantly, whereas in RGR reverse trend was observed. Maximum mustard yield (1804.3 kg ha-1) was obtained from RH-9707 followed by RH-9304 (1771.4 kg ha-1)genotype. Yield increased significantly only up to 80 kg N ha-1.
