Response of NPK and sulphur on soil health parameters and yield attributes of mustard (Brassica juncea L.) var. Nirmal-111

Abstract

Present paper investigation entitled “Response of NPK and Sulphur on Soil Health Parameters and Yield attributes of Mustard (Brassica juncea L.) var. Nirmal-111” was carried out at central research farm of Department of Soil Science and Agricultural Chemistry, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj during rabi season 2023-24. The texture of the soil in the experimental region was sandy loam. The design was set up using randomized block design, different levels of NPK (0:0:0, 60:30:20 & 120:60:40 kg ha-1) and Sulphur (0, 25 & 50 kg ha-1) respectively. The findings it is concluded from trail that the treatment T9 [N:P:K @ 120:60:40 kg ha-1 + S @ 50 kg ha-1] gave the best results and significant increase in terms of pore space, water holding capacity, EC, organic carbon, available nitrogen, available phosphorus, available potassium and available sulphur as well as plant growth and yield attributes. The maximum yield was recorded as 18.20 qha-1 in treatment T9 [N:P:K @ 120:60:40 kg ha-1 + S @ 50 kg ha-1] and minimum 8.20 qha-1 in T1 [Absolute control] respectively which was higher than yield any other treatment combination. Among the various treatments, treatment T9 [N:P:K @ 120:60:40 kg ha-1 + S @ 50 kg ha-1] provided the highest net return of ₹34551.76 ha-1 followed by treatment T8 [N:P:K @ 60:30:20 kg ha-1 + S @ 25 kg ha-1] ₹32688.42 ha-1. However, the control plot treatment showed lowest net returns of ₹5615 ha-1. There was no discernible difference in the growth and production of mustard under control. The use of Sulphur, as well as their blend with complete NPK, significantly increases the characteristics of growth and total yield attributes of mustard. The trail was based on one season, so that the findings can be substantiate before recommendation.
