Abstract

The potassium, calcium and magnesium content of maize leaves is discussed in relation to fertilizer treatment on a ferrallitic soil of the Farningham series. The relationship between cation content of maize leaves and grain yield is also reported. Potassium content of the leaves was markedly improved by potassic fertilizer application and this resulted in increased grain yield. Dolomitic lime increased the calcium and magnesium content of the leaves and also grain yield but depressed leaf K. Data are presented to show the effects of nitrogenous and phosphatic fertilizers on the cation content of the leaves; the interrelationships between the cations are also discussed.
