Abstract
The present study in pot experiments was conducted on “Influence of phosphorus and sulphur application on sesame yield in high P soils of Telangana”. The experiment was conducted in two different levels of high phosphorus status soils with 67.29 kg P2O5 ha-1 in soil 1 (S1) and 83.46 kg P2O5 ha-1 in soil 2 (S2). The treatments were taken in factorial completely randomized design in combination of five levels of phosphorus (P0-0, P25- 5, P50-10,P75-15 and P100-20 kg ha-1 of soil) four levels of sulphur (S0-0,S1-10,S2-20 and S3-30 kg ha-1 of soil). A significant increase in seed yield of sesame crop could be achieved by combined application of P75 (15 kg P2O5 ha-1) + S20 (20 kg S ha-1) in high available phosphorus soils. Among the various treatments tested within two high P soils, in S1 maximum seed (11.89 g pot-1) and stalk yield (21.98 g pot-1) was obtained with combined application of P75 (15 kg P2O5 ha-1) + S20 (20 kg S ha-1) while in S2 maximum seed (11.92 g pot-1) and stalk yield (21.89 g pot-1) was obtained with combined application of P50 (10 kg P2O5 ha-1) + S20 (20 kg S ha-1).
