Abstract

A pot oulture experiment was laid out with the acid soil of Nanjanad, Nilgiris district to determine the effect of lime on the yield and composition of groundnut. The growth and yield of groundnut haulms, pods and kernels were found to be increased by the application of lime alone at 7000 lb. per acre and in combination with superphosphate at 60 lb. P.Os per acre. Both the calcium and phosphorus content of the crop were also increased by the application of lime and superphosphate. Tho CaO/P-Os ratio in the crop increases as the crop approaches maturity and the ratio in the groundnut kernel is very low as compared to groundnut haulms and shells.
