Abstract: A field experiment was conducted to study the “Effect of planting density on brown sarson (Brassica campestris var. brown sarson) under different levels of nitrogen and phosphorus in mid-hills of Himachal Pradesh” during Rabi season of 2014-15 at the Research Farm of Department of Agronomy, Forages and Grassland Management, CSKHPKV, Palampur. The treatments comprising of 3 planting densities, 3 nitrogen levels and 2 phosphorus levels were replicated thrice using factorial randomized block design. Results have shown that yield attributes of brown sarson viz. primary and secondary branches per plant, no. of siliquae per plant, seeds per siliqua, 1000-seed weight were found to be significantly higher at 25 plants/m² but 90 kg N/ha and 60 kg P₂O₅/ha showed similar positive effect on yield attributes also. higher seed yield was recorded in treatment combination of 50 plants/m² alongwith 60 kg N/ha and 60 kg P₂O₅/ha. Higher gross and net returns were obtained from the planting density of 50 plants/m² which also gave higher B:C ratio.
