Abstract:
The research work was conducted at Sher-e-Bangla Agricultural University Farm,
Dhaka during the Rabi season of November, 2019 to March, 2020 to study the
effects of zinc (Zn) and boron (B) on the growth and yield of chili. Two factor
experiments with Randomized Complete Block Design (RCBD) was followed
with 9 treatments (Zn

yield parameters of chili were significantly affected and increased with increasing
levels of Zn and B. The tallest plant (76.67 cm), maximum value of number of
