Abstract

Two varieties of tomato were sown to determine the effect of NPK on tomato plants by using them independently under normal field conditions. Application of urea delayed flowering and fruit setting in both the varieties, but increased the number of fruit set, weight of fruits harvested per plant, weight of individual fruits and fruit yield/ha. Muriate of potash and controlled treatments did not have significant influence on yield components. Super phosphate treatment, however, gave better results then potash and controlled treatments for number of fruits set, and harvested fruit weight/plant and average weight/fruit and yield/ha. The average yield of Roma was significantly higher than that of Moneymaker in urea and super phosphate plots.
