- The production of oil from the conventional oilseed seed crops (viz. mustard, rapeseed) is not sufficient to meet the demands of Pakistani people. Due to this reason, a surplus quantity of oil is imported every year from different countries to fulfill the domestic demands of the cooking oil. This 2-year study was aimed to optimize the dose of NPK for profitable production of white mustard. Nitrogen (0, 60, 90 kg ha⁻¹), phosphorous (0, 30, 60 kg ha⁻¹) and potassium (0, 75, 100 kg ha⁻¹) were applied in various combinations. The results indicated that highest seed yield and profitability was recorded with NPK at 90–60–100 kg ha⁻¹, which was attributed to improvement in crop growth. In crux, application of NPK at pre-optimized rate might be a viable option to improve the growth, yield, oil quality, and economics of white mustard production under arid climates in Pakistan. According to the results, a balanced use of NPK fertilization is a key management strategy for white mustard growing farmers of arid region.
