Abstract:
The study titled “Response of different levels of phosphorus and sulphur on yield of black gram (Vigna mungo L.) in Chhattisgarh plain” was conducted during the kharif season in 2022 at the Instructional Farm, BTCCARS, Bilaspur (C.G.). The treatments consisted of four phosphorus levels (0, 20, 40, and 60 kg ha^-1) and three sulphur levels (0, 10, and 20 kg ha^-1). The results showed that increasing the phosphorus application rate significantly increased the grain yield, with the highest yield of 13.15 q ha^-1 obtained with 60 kg P ha^-1 compared to only 7.65 q ha^-1 with no phosphorus application. The 20 kg S ha^-1 sulphur treatment produced the maximum grain yield of 11.49 q ha^-1 across sulphur levels. Other yield attributes like pods plant^-1, seeds pod^-1, and test weight also improved with higher phosphorus doses. The findings highlight the importance of optimal phosphorus and sulphur nutrition in realizing the yield potential of black gram in this region. The study demonstrates the significant positive response of black gram to applied phosphorus and sulphur in terms of enhanced grain and biomass yields.
