A field experiment was conducted in Rabi 2011-12 to study the effect of different N levels with and without P and K on growth, yield and acquisition of nutrients by mustard (Brassica juncea L). The experiment was laid out in randomized block design (RBD) with 12 treatments. The results revealed that highest significant grain yield of 20.78 q ha-1 were recorded in the treatment T12 (N120P50K50) as compared to all other treatments. Addition of different N levels with and without P and K, caused significant increase in plant height, number of branches plant-1 (primary and secondary), number of siliquae plant-1, number of seed siliquae-1, 1000-seed weight, biological yield, seed yield, stover yield q ha-1, nutrient content and uptake. On the basis of results obtained it can be concluded that the balanced fertilization and high dose of nitrogen with P and K was found superior than alone application of treatments due to synergetic effect of N with P and K by mustard in terms of growth and yield parameters significantly.
