Abstract
A pot culture experiment was conducted on “Influence of Phosphorus and Sulphur Application on Nutrient Content and Uptake by Sesamum in High Phosphorus soils of Telangana”. In this experiment, two high phosphorus status soils were selected consisting of 67.29 kg P 2 O 5 ha -1 and 83.46 kg P 2 O 5 ha -1 . Treatments mainly include five levels of phosphorus (P 0 -0, P 1 – 5, P 2 -10, P 3 -15 & P 4 -20 kg ha -1 of soil) and four levels of sulphur (S 0 -0, S 1 -10, S 2 -20 & S 3 -30 kg ha -1 of soil) and it was conducted factorial completely randomized design. Results indicated that a significant increase in nutrient content and uptake by sesamum crop could be achieved by combined application of 15 kg P 2 O 5 ha -1 ( 75 % RDP ) + 20 kg S ha -1 in both high available phosphorus soils. Among the various treatments tested, the highest nutrient content and uptake by sesamum crop was recorded with a combined application of 75 per cent RDP (15 kg P 2 O 5 ha -1 ) + 20 kg S ha -1 in soil 1 and 50 per cent RDP (10 kg P 2 O 5 ha -1 ) + 20 kg S ha -1 in soil 2.
