Abstract

An interrelation of N, K and Ca on storage life, solid, acids and other fruit characters were determined on tomatoes (Var. 'improved Harbot') by applying varying levels of (NH4)2SO4, KC1 and CaC12

High N and K levels shortened the storage life, whereas Ca prolonged the marketability of the fruit.

Excessive applications of N significantly increased the percentage of N in the fruit in contrast with applied K and Ca.

Fruit acidity was increased by applying high levels of N, K and Ca. Soluble solids in the fruit increased with N and Ca, but decreased with K application.

Ripening and maturity were delayed by applying high levels of K and apparently not affected by Ca.
