INFLUENCE OF GA 3 AND BORON ON GROWTH AND YIELD OF SUMMER TOMATO

Abstract

A pot experiment was conducted at the Horticultural Farm of Sher-e-Bangla Agricultural University, Dhaka from April 2018 to September 2018 to study the effect of GA 3 and boron on the growth and yield of summer tomato, (CV- BARI Hybrid Tomato-4). There were four concentrations of GA 3 viz. G 0 : 0 ppm, G 1 : 50 ppm, G 2 ii : 100 ppm and G 3 : 150 ppm and three levels of boron viz. B 0 : 0 ppm, B 1 : 25 ppm and B 2 : 50 ppm. The experiment was laid out in a Completely Randomized Design (CRD) with 3 replications and there were altogether 36 pots. Application of GA 3 and boron significantly influenced the growth, yield and size of tomato. The highest yield (1600.87 g/plant) was found from G 2 and the lowest yield (678.85 g/plant) was obtained from G 0 . Due to application of boron, the highest yield (1515.31 g/plant) was obtained from B 1 and the lowest yield (794.14 g/plant) was recorded from B 0 . In case of combined effect, the highest yield (1689.44 g/plant) was found from G 2 B 1 and the lowest yield (487.41 g/plant) was found from G 0 B 0 . So, application of 100 ppm GA 3 along with 25 ppm boron was the best for growth and yield of tomato.
