Economics and influence of fertility levels on growth and yield of Indian mustard (Brassica juncea Coss) under irrigated condition

A field experiment was conducted during the Rabi at the research farm, Janta Vedic College Baghpat, to evaluate the economics and influence of fertility levels on growth and yield of indian mustard (Brassica juncea Coss) under irrigated condition. Among the different levels of treatments applied then the application of Nitrogen @ 100 kg/ha or Phosphorus @ 80 kg/ha increase growth parameters and yield than other treatments in comparison, there by resulting significant increase in growth and yield attributes viz. plant height (178.34 and 177.84 cm), no. of branches/plant (7.94 and 7.92), dry matter accumulation, no. of siliquae/plant and seeds/ siliquae, seed (15.94 to16.58 q/ha) and straw yield of Indian mustard. Application of Nitrogen @ 100 kg/ha or Phosphorus @ 80 kg/ha increased the yield of Indian mustard significantly over other treatments, besides realised at B: C. ratio of 2.34 to 2.36. The highest gross returns Rs 25450 and 25555 per hectare and highest net returns of Rs 14551 and Rs 14731 per hectare was recorded with Nitrogen @ 100 kg/ha or Phosphorus @ 80 kg/ha
