Studies on the Effect of Phosphorus and Potassium on the Yield and Shelling Percentage of Groundnut

Abstract

A pot experiment was conducted to study the effect of phosphorus and potassium on the yield of pode, haulms and shelling percentage in groundnut in the calcareous and non-calcareous red sois of Tamil Nadu. The non calcareous red soil recorded significantly higher yield of pads. Application of phosphorus and potassium significantly increased the yield of pods and the highest pod ylein was obtained by the combined application of 60 kg Pa Os/ha and 90kg K, O/ha. Phosphorus alone significantly increased the yield of haulms. The shelling percentage was increased by the application of both phosphorus and potassium.
