Abstract
A field experiment was conducted at Research Farm, Chatha, Jammu during the winter season of 2022-23 to study the effect of different fertility levels with FYM (farm yard manure) enriched macro and micronutrients on productivity, nutrient uptake and quality of Indian Mustard. The treatment consisted of three fertility levels viz., F1: control; F2: 100% NPK (60:30:15 kg/ha); and F3: 125% NPK (75:37.5:18.75 kg/ha) in main plots and seven macro and micronutrient treatments namely, N1: control; N2: 20 kg S+2.5 kg Zn+0.5 kg B/ha; N3: 30 kg S+3.75 kg Zn +0.75 kg B/ha; N4: 40 kg S +5 kg Zn + 1 kg B/ha; N5: 20 kg S+2.5 kg Zn + 0.5 kg B/ha enriched with FYM @ 500 kg/ha; N6: 30 kg S+ 3.75 kg Zn +0.75 kg B/ha enriched with FYM @ 500 kg/ha; and N7: 40 kg S+5 kg Zn + 1 kg B/ha enriched with FYM @ 500 kg/ha in sub plots, which were laid out in split plot design with three replications. The results showed that the application of F3: 125% NPK (75:37.5:18.75 kg/ha) along with N7: 40 kg S+5 kg Zn + 1 kg B/ha enriched with FYM @ 500 kg/ha recorded a significant increase in yield attributes, seed and oil yield, nutrient uptake as well as gross and net returns. However, the highest B: C was achieved with the application of F3: 125% NPK (75:37.5:18.75 kg/ha) in combination with N5: 20 kg S+2.5 kg Zn + 0.5 kg B/ha enriched with FYM @ 500 kg/ha.
