Abstract:
An experiment was conducted at the Horticulture Farm of Sher-e-Bangla
Agricultural University, Dhaka during November 2020 to March 2021 to study the
influence of biofertilizer with zinc and boron on the growth and yield of black
cumin. Black cumin variety BARI Kalozira-1 was used as planting material in this
study. The experiment consisted of two factors: Factor-A: biofertilizer (4 levels):

. The experiment was laid out in a randomized
complete block design (factorial) with three (3) replications. Data on different
growth, yield contributing and yield parameter of black cumin were recorded and
significant variation was observed from different treatments. In case of
biofertilizer the tallest plant (54.19 cm) was observed from T

black cumin providing 12 kg biofertilizer with 4 kg Zinc and 2 kg Boron along
with RDF was recorded to be more suitable practice for getting higher amount of
seed of black cumin.
