Abstract

A study was conducted at Chinnathadagam, Coimbatore during the year 1987-88 with three levels of nitrogen (0,20 and 40 kg ha¹), four levels of phosphorus (0, 20, 40 and 60 kg ha¹). five levels of potassium (0, 30, 60, 90 and 120 kg ha) and three levels of farm compost (0, 6 and 12 tha) to find out the influence of soil test methods on pod yield, response and uptake of nitrogen, phosphorus and potassium in groundnut Co.1. Significant positive correlations were obtained between the soil test methods and the pod yield of groundnut. However, with uptake the KMnO4 - N had a negative relationship evidencing that significant contribution of N is from the native source.
