Abstract
A field experiment was carried out to evaluate the response of Zn, B and Cu on
the yield and quality of boro rice at the research farm of Sher–e–Bangla
Agricultural University, Dhaka, Bangladesh during the period from January to
May, 2016. The experiment consisted of single factor with 5 different

(control). The
experiment was laid out following Randomized Complete Block Design
(RCBD) with four replications. The micronutrients (Zn, B and Cu) along with
recommended doses of NPK had significant influence on the growth, yield and
yield contributing characters of rice. The maximum weight of 1000 grain
(23.82 g) was gained by T

and the minimum weight of 1000 grain (20.31 g)
was gained by T
