Abstract: Recent reports indicated that more than 80 per-cent of soils in Nizamabad, Kamareddy, Rajanna Siricilla, Karimnagar, Siddipet, Jagtiyal and Peddapalli districts of Telangana state have high P soils.Hence, the above study was conducted as there was little information on the impact of various sulphur levels on sesamum grown in high P soils. MATERIALS and METHODSInitially, soils were screened for available phosphorus in and around Ranga Reddy district.Based on available phosphorus status, two soils were selected for conducting pot culture -1 -1 experiment S1 (67.29 kg P2O5 ha ) and S2 (83.46 kg P2O5 ha ).In the above-selected soils (S and S ) pot culture experiment 1 2 was conducted with sesamum as test crop (JCS 1020) during summer 2022-23 at the Agricultural Research Institute, Rajendranagar and Hyderabad.Initial soil characteristics of the experimental soil was done by following standard procedures and are presented in table 1. Treatments mainly comprise of ive levels of phosphorus (P0-0, -1 P -5, P -10, P -15 and P -20 kg P2O5 ha of soil), four levels of 1 2 3 4 -1sulphur (S₀-0, S₁-₁0, S₂-20 and S₃-30 kg S ha of soil) with a total of twenty treatmental combinations with four replications laid out in Factorial Completely Randomized Design.The recommended dose of fertilizers for sesamum is 60-20-20 kg N, P2O5 & K2O ha-¹.Nitrogen, phosphorus, potassium and sulphur nutrient requirements were met through Urea, diammonium hydrogen phosphate, potassium chloride and potassium sulphate respectively.Entire dose of phosphorus, potassium and sulphur were applied as basally for all the pots as per the treatments while ifty percent of nitrogen was applied as basal.The remaining ifty percent of nitrogen was applied at 30 DAS.All the prophylactic plant protection measures were adopted as and when needed during the crop growth period.Statistical analysis was carried out as per the procedures [16].
