Abstract

A field experiment was laid out during the kharif 2020 at Prakasam Krishi Vignan Kendra (KVK), Jayaprakashnagar, Jammikunta, Karimnagar District-505122 Telangana State to know the effect of Potassium and Sulphur on growth and yield of groundnut. Groundnut is cultivated in 2.0 lakh hectares across Telangana region making it one of the major crops of the state. It is widely grown in Mahbubnagar, Warangal, Nalgonda and Karimnagar Districts. The experiment consists of 12 treatments which included 4 levels of Potassium (0kg, 25kg, 50kg and 75kg) and 3 levels of Sulphur (0kg, 20kg and 40kg). The treatment receiving 75 kg potassium and 40kg Sulphur produced significantly higher plant height (49.93), number of nodules/plant (127.47), plant dry weight (37.43), crop growth rate (24.45), number of pods/plant (12.23), number of seeds/pod (2.08), test weight (41.32), seed yield (2677.97), halum yield (4573.89), harvest index (36.91), gross return (1,36,576.30 INR/ha) net return (90,292.86 INR/ha) a

Keywords

Groundnut, Potassium and Sulphur.

Conclusion

Based on the findings it may be concluded that for optimum Seed yield and economics, the performance of Groundnut at 75 kg/ha Potassium + 40 kg/ha Sulphur is the best. Groundnut is generally grown on coarse-textured or sandy soils which are inherently low in SO4² and -S and are highly prone to leaching losses of SO42. Grain legumes and oil seeds have high sulphur requirement therefore Groundnut being a both a legume and an oilseed crop has high sulphur requirement. The conclusion drawn based on one season data only which require for further conformation for recommendation.
