Abstract:
An experiment was carried out at the Soil Science research field, Sher-e-Bangla
Agricultural University, Sher-e-Bangla Nagar, Dhaka-1207 during the period from
November 2020 to April 2021 to find out the effect of micronutrients (Zn and B) on
the growth and yield of BARI Tomato-15. The experiment was laid out in a
Randomized Completely Block Design (RCBD) having twelve (12) treatments with
three replications. The unit plot size was 6 m

zinc and boron treatments (T

distributed randomly in individual plots. The total number of plots was 36. Different
levels of zinc and boron as micronutrient had significantly varied the all yield and
growth parameters. It was clearly found that, the maximum plant height (99.50 cm),

the present investigation revealed that tomato can be grown successfully at the use of
150% of boron and 50% of zinc, tomato gave more yield. The findings of the present
investigation clearly indicated that the efficient use of boron and zinc doses and
growing tomato is a viable option for increasing income of farmers.
