Effect of integrated nutrient management practices on productivity and profitability of Indian mustard (Brassica juncea L) grown under rainfed condition

Abstract

Field experiments were carried out during 2019-20 and 2020-21 to find out the effect of integrated nutrient management practices on productivity and profitability of Indian mustard (Brassica juncea L.) grown under rainfed condition. Thirteen treatments having different combinations of NPK doses with and without FYM and a control (no fertilizer) were laid out in a complete randomized block design in triplicate. Results revealed that application of 30:30:15 kg NPK/ha (inorganic) + 30 kg N/ha (FYM) recorded the highest plant height, number of primary branches/plant, number of secondary branches/plant, number of siliquae/plant, seed yield (3079 and 3161 kg/ha) and stover yield (7706 and 7901 kg/ha) during both the years. Similarly, highest net returns (₹ 103912 and ₹ 117353/ha) and rainwater-use efficiency (48.5 and 99.1 kg/ha-mm) were also recorded with the treatment receiving 30:30:15 kg NPK/ha (inorganic) + 30 kg N/ha (FYM) during both the years. However, application of 60:30:15 kg NPK/ha resulted the highest benefit: cost ratio (4.20 and 4.62) during both the years.
