A field experiment entitled “Response of Sulphur and Weed Management Practices on Cowpea [Vigna unguiculata L.]” was conducted on loamy sand soil at research farm, School of Agricultural Science, Suresh Gyan Vihar University, Jaipur, Rajasthan during Kharif 2023 seasons. The field experiment design was randomised block design with ten treatments. Cowpea variety RC-101 was sown row spacing 30 cm and seed rate 40 kg ha-1. Maximum accumulation of dry matter per plant of cowpea in application of sulphur (30 kg ha-1) + hand weeding twice (20 and 40 DAS) (16.17 g plant-1) and followed by sulphur (2030 kg ha-1) + hand weeding twice (20 and 40 DAS) (15.68 g plant-1), sulphur (30 kg ha-1) + pendimethalin (0.75 ml ha-1) pre-emergence (15.05 g plant-1). The increase seed yield due to sulphur (30 kg ha-1) + hand weeding twice (20 and 40 DAS), sulphur (20 kg ha-1) + hand weeding twice (20 and 40 DAS), sulphur (30 kg ha-1) + pendimethalin (0.75 ml ha-1) pre-emergence, sulphur (10 kg ha-1) + hand weeding twice (20 and 40 DAS) in the tune of 53.72, 45.67, 44.72 and 39.44 percent respectively, over to control. Maximum net return and B: C were recorded with application of sulphur (30 kg ha-1) + pendimethalin (0.75 ml ha-1) pre-emergence (Rs 32130 ha-1) and (2.03).
