abstract
The field experiment on farm trial (OFT) was conducted on “Effect of Sulphur and Boron application of Mustard (Brassica juncea L.) crop, Grain Yield through conduct on Farm Trails at Farmers Fields District Shravasti” during the Rabi season of the year 2022-23 and 2023-24 in order to develop fertilizer prescriptions for the desired yield targets treatments viz., T₁-Farmers Practices, T₂- Recommended dose of fertilizer (RDF) and T₃- Recommended dose of fertilizer (RDF)+Refinement treatment use Sulphur and Boron. In this experiment application of chemical balanced fertilizers- N- 120 kg/ha, P- 40 kg ha^-1, K- 40 kg ha^-1 +Sulphur 5 kg ha^-1 and Boron 2 kg ha^-1 (Whole P and K+1 /3 N as Basal dose & remaining N as Two split at 25 and 45 DAS+ Boron Foliar spray at before Flowering stage) increased 38.0 per cent in economic yield than the farmers practice during the year. The net return also showed increase of Rs. 65277/- ha^-1 under chemical balanced fertilizers - N- 120 kg ha^-1, P- 40 kg ha^-1, K- 40 kg ha^-1 +Sulphur 5 kg ha^-1 and Boron 2 kg ha^-1. Application of Boron Foliar spray at flowering recorded maximum yield (18.69 q ha^-1) higher net return (Rs. 65277 ha^-1) with benefit cost ratio of 1.77.
