Effect of sulphur and phosphorus on growth and yield of groundnut

Abstract

In 2023, a field experiment was carried out at the Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P.) during the kharif season. The experimental soil had a sandy loam texture with a pH of 7.3, organic carbon at 1.13%, nitrogen at 278.48 kg/ha, phosphorus at 48.1 kg/ha, and potassium at 253.5 kg/ha in terms of soil reactivity. Along with control, the treatments include phosphorus (40, 50, and 60 kg/ha) and sulphur (30, 40, and 50 kg/h). Ten treatments, each replicated three times, were used in the experiment, which was set up using a randomised block design. The growth characteristics, such as the maximum plant height (50.03 cm), dry weight (38.97 g), number of nodules per plant (60.00), and yield features, such as the number of kernels per pod (2.00), pods per plant (17.00), kernel yield (2422.22 Kg/ha), and haulm production (3583.33 Kg/ha), were demonstrated by the results were recorded significantly higher with application of treatment 50 Kg/ha Sulphur + 60 Kg/ha Phosphorus in groundnut crop.
