A thrice replicated field trial was conducted in Rabi season 2009-10 to evaluate 5 nitrogen rates and 2 zinc fertilizer rates on growth, yield and quality of Indian mustard. The experimental results revealed that application of 100 kg N/ha recorded significantly maximum growth attributes viz., plant height (cm), number of total (primary + secondary) branches/plant, total dry matter accumulation at 60, 90 DAS and harvest stage, dry matter g/plant husk, stem as well as total and seed, straw as well as total, yield attributes (no of siliquae per plant, length of siliquae per plant, number of seed per siliquae, seed weight per siliquae, 1000 seed weight, seed weight per plant) and yield such as grain yield (1804 kg/ha), biological yield (8406 kg/ha) and harvest index (21.6 %), besides achieved better protein content and, protein and oil yield. Although, maximum oil (42.3 %) content was recorded in a plot where N was absent. Moreover, like as above, application of 20 kg/ha zinc recorded maximum growth, yield and quality of Indian mustard over control plot.Thus, the combination of nitrogen @ 100 kg/ha and zinc @ 5 kg Zn/ha appeared to be more promising to boost the productivity of B. juncea on one hand and to improve its quality on the other.
