EFFECT OF BORON AND ZINC ON GROWTH, YIELD AND NUTRIENT CONTENT OF BAR! TOMATO-2

Abstract

An experiment was conducted in the experimental field of Sher-e-Bangla Agricultural University. Dhaka during the period from November 2013 to March 2014 to find out the effect of boron and zinc on the growth. yield and nutrient content of BARI Tomato-2. The experiment consisted of four levels of boron i.e 0. 1.0. 1.5 and 2.0 kg B ha1; three different levels of zinc namely 0. 2.5 and 5.0 kg Zn haS'. The experiment was laid out in a RCBD with three replications. Both boron and zinc had significant influence on growth and yield contributing characters of tomato. At 75 DAT. the highest plant height (117.30cm). maximum number of leaves per plant (75.30) and highest yield (67.36 ton haS') were recorded from boron application at 2.0 kg haS'. At 75 DAT. the highest plant height (113.60 cm). maximum leaves per plant (67.00) and yield (65.85 ton haS') were recorded from zinc application at 2.5 kg haS '. The combined eflèct of 2.0 kg B ha1 and 2.5 kg Zn haS' performed the highest yield (86.25 ton haS ') and lowest from B0Zn0 i.e.: control treatment. So, 2.0 kg B haS' and 2.5 kg Zn ha' may be used for higher yield of tomato.
