Abstract:
A field experiment was conducted at the Horticulture farm of Sher-e-Bangla
Agricultural University, Sher-e-Bangla Nagar, Dhaka during October 2019 to July
2020 to study the effect of different levels of vermi-compost and macro nutrients
on the growth and yield of garlic. Garlic variety ‘BARI Rashun-3’ was used as
planting material in this study. The experiment consists of single factor. Twelve
treatment combinations were tested in this experiment: T

vermi-compost + 100% NPKS (RDF) and T
vermi-compost + 100% NPKS (RDF). The experiment was laid out in
Randomized Complete Block Design (RCBD) with 12 treatment combinations
having three replications. Data on different growth and yield parameter of garlic
were recorded and significant variation was observed for different treatments.
Plant height and number of leaves plant

value of garlic was recorded to be the
maximum from treatment T

vermi-compost + 100% NPKS (RDF)) at
different days after sowing (DAS). But, the highest bulb diameter (3.32 cm), the
longest clove (3.44 cm), the highest bulb length (2.43 cm), the maximum number
of cloves bulb

(21.25), the maximum fresh weight of bulb (35.11 g), the
maximum dry weight of bulb (4.95 g), the highest fresh clove weight (6.93 g), the
maximum dry clove weight (1.89 g), the maximum fresh weight of leaves plant
(25.31 g), the maximum dry weight of leaves (3.31 g), the highest bulb yield plot
(1.45 kg) and the maximum yield of garlic (14.53 t ha

) was recorded from T11
(6.00 t ha
-1
vermi-compost + 100% NPKS (RDF) treatment. The highest benefit
cost ratio (2.57) was attained from the treatment combination of T
vermi-compost + 100% NPKS (RDF)). The second best benefit cost ratio (2.52)
was acquired in T
10
(4.0 t ha
-1
vermi-compost + 100% NPKS (RDF)).
