Abstract : Mango leaf P and K contents declined with age whereas the Ca content rose. Basal leaves contained more P and K and less N and Ca than terminal leaves on the same shoot but the differences between fruiting and non-fruiting shoots were slight. Practical suggestions are made for sampling mango leaves.
