Effect of major, secondary and micro nutrients on growth, yield and economics of Indian mustard (Brassica juncea L.)

A field experiment was carried out under sandy loam soil during rabi season of 2022- 23 at the Agricultural Research Farm, Tirhut College of Agriculture, Dholi, Dr. Rajendra Prasad Central Agricultural University, Pusa (Samastipur), Bihar, (India) with the combination comprising different levels of major, secondary and micro nutrients to evaluate their effect on the growth, yield and economics of Indian mustard. The results of experiment indicated that overall growth of the crop viz., plant height, number of branches/plant and dry matter accumulation and physiological parameter RGR at different growth stages, yield attributes and yield viz., number of siliquae/plant, length of siliquae, number of seed per siliquae, seed, straw and biological yields were significantly higher with the application of 150%ha-1 in mustard as compared to rest of major, secondary and micro nutrients treatments combinations. However, application of 150% ha-1 also recorded higher net returns (Rs.89581 ha-1) B: C ratio (1.69). Although higher net returns in secondary and micro nutrients combination with the application of 40 kg S + 5 kg Zn + 1 kg Bha-1, enriched with 500 kg FYM ha-1 was recorded highest net returns (Rs. 68919 ha-1) and the treatment 20 kg S + 2.5 kg Zn + 0.5 kg Bha-1 enriched with 500 kg FYM ha-1 recorded the highest B: C ratio (1.41).
