Abstract
The interrelations of N, K and Ca on storage life, solids, acids and other fruit characters were determined on tomatoes (Var. 'Improved Harbot') by applying varying levels of(NH4)2SO4, KCl and CaCl2.
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.
