Abstract


A pet experiment was conducted with groundnut POL 2 In the calcareous and non-calcareous red soils of Tamil Nadu, to study the influence of phosphorus and potassium on the quality of groundnut namely protein content, oil content, yield of oil and quality of wit. The onloaroous rod coil recorded significantly higher value for crude protein content. wherees the non-calcareous red soil recorded significantly higher value for all content of kernels and yield of oil. Both phosphorus and potassium application increased the crude protein contant, nil contant and yield of oil.
