RELATIONSHIP BETWEEN FRUIT SIZES AND NUTRIENT CONTENT OF GREENHOUSE TOMATOES AND CUCUMBERS

Abstract
Analysis of greenhouse tomato and cucumber fruits for their content of N, P, K, Ca and Mg showed that very small fruits contain relatively high percentages of these nutrients. Beyond a certain size the levels are somewhat lower and remain constant throughout the whole process of sizing. Nutrient absorption keeps pace with size even though growth may follow an erratic time sequence. The levels may differ in different parts of the plant but they are uniform for all fruit sizes in each part.
