Abstract:
A field experiment was conducted at the research field of Sher-e-Bangla Agricultural
University, Dhaka during the period from from October 2021 March 2022 in the Rabi
season to study the influence of micronutrients and their application methods on seed
yield of broccoli. The experiment consisted of two factors and followed Randomized
Complete Block Design (RCBD) with three replications. Factor A: Levels of
micronutrients (4) viz; F

result revealed that in case of micronutrients application the highest number of pods
per plant (2204.90), seeds per pod (8.31), seed weight per pod (19.25 g), seed yield
per plant (34.66 g), seed yield per plot (311.97 g), seed yield per hectare (1155.40 kg)
and seed germination percentage (86.64 %) were observed by F

treatment. In terms of different methods of fertilizer applications, the highest number
of pods per plant (2008.2), seeds per pod (7.33), seed weight per pod (17.42 g), seed
yield per plant (30.87 g), seed yield per plot (277.79 g) as well as seed yield per
hectare (1028 kg) were recorded from M
(Foliar spray before flowering). When
applied together application of Zn

through foliar spray before flowering affected broccoli plant growth and yieldcontributing
characteristics, leading to the maximum seed yield per plant (39.17 g),
seed yield per plot (352.57 g) and seed yield per hectare (1305.80 kg). Therefore, it is
suggested that application of Zn
