Effect of S and Zn with N P K on yellow mustard (Brassica campestris L.): An economic analysis

The field experiment was carried out at Department of Soil Science, Sam Higginbottom Institute of Agriculture, Technology and Science, Allahabad, India during rabi season. The experiment was laid out in 3×3 factorial randomized block design with 9 treatments in three replications. It indicates that application of sulphur and zinc increased the total cost of cultivation of yellow mustard markedly. The maximum total cost of cultivation (` 34610.68 ha−1) and the minimum net return (` 18159.72 ha−1) was computed with application of 30 kg S ha−1 and 5.5 kg Zn ha−1 while the maximum net return `−1 invested (1.89) was recorded with the application of 45 kg S ha−1 and 1.35 kg Zn ha−1. There should be a chance of better yield and net income, suggested all operations will be performing timely for this crop, because time is a very important factor and play great role for greater yield and its quality, before time or after time any operations in the field of agriculture production and quality will goes down. However, since these findings are based on one-year experiment and therefore, further research may be conducted to substantiate it under Allahabad agro climatic conditions.
