N and K contents ofleavesaveraged over genotypes for fertilizers increased significantly from 1.40 and 0.46 per cent of dry matter in the no fertilized plots, tol-55andO-92per cent respectively in plots receiving highest amount offertilizers (1-0 kg N, 10 kg P2O6 and 20kgKaO per tree in an year). There was an inverse relationship between K and Mg content of leaves but Ca content did not vary much- Leaf P content did not increase significantly. However, available Pin surface soil of highest: fertilizer treatment increased significantly (131 ppm) over that of no fertilizer (20 ppm), whereas the corresponding values of exchangeable K increased from 23 to 59 ppm. But available nitrogen in soil did not vary. The variations between genotypes and genotype X fertilizer interaction were nonsignificant.enArticle
