EFFECTS OF FOLIAR APPLICATION OF BORON AND ZINC ON THE GROWTH AND YIELD OF TOMATO

Abstract

An experiment was conducted at the Horticulture Farm, Hajee Mohammed Danesh Science and Technology University, Dinajpur during November 2017 to March 2018 to study the effects of foliar application of Zinc and Boron on growth and yield of tomato. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. The experiment consisted of two factors: (1) three different levels of zinc, viz. 0 ppm, 25 ppm, 50 ppm of ZnS04 and (2) three different levels of Boron, viz.0 ppm, 25 ppm, 50 ppm of H3BO3. The seedlings were transplanted on 22 November 2017, and the tomato was harvested on different dates from February to March, 2018 depending on maturity. Boron had significant effect on all yield attributes and yield of tomato. Foliar application of 50 ppm of H3BO3 produced the highest tomato yield (85.33 ton/ha) through increasing plant height, number of leaves per plant, number of branches per plant, number of flower cluster per plant, number fruits per plant, weight of fruits per plant, individual fruit weight, fruit length, fruit diameter and yield/ha of fruits. Maximum yield of Tomato (88.67 ton/ha) was obtained from 25 ppm of ZnS04. A combination of 25 ppm H3B03 and 25 ppm ZnS04 gave the highest yield of tomato (89.24 ton/ha) than control (45.48 ton/ha). So, application of 25 ppm H3B03 along with 25 ppm ZnS04 was the best for growth and yield of tomato.
