A study was taken up in the red lateritic soil of Vridhachalam to find out the effect of N, K, and FYM on the yield and uptake of nutrients in groundnut. The trial was conducted in three seasons in a randomised block design with 32 treatment combinations which consisted of 2 levels of FYM (0 and 6.25 tons/ha) four levels of N (0, 9, 18 and 27 kg N/ha), and four levels of K (0, 27, 54 and 81 kg K2 0/ha). The results showed that application of 9 kg N, 54 kg K2 0 and 6.25 tons FYM/ha significantly increased groundnut pod yield over the other levels tried. Oil content in kernel was enchnced by K application at 54 kg and 81 kg K2 0/ha. N and P uptake were increased by application of FYM at 6.25 t/ha and K at 54 kg K2 0/ha respectively.
