Abstract:
The experiment was carried out at the “Horticulture Farm” of Sher-e-Bangla
Agricultural University, Dhaka, Bangladesh during October 2019 to January 2020 to
study the effect of different organic and chemical sources of potassium and seedling age
at transplant on growth and yield of kohlrabi. The experiment consisted of two factors.
Factor A: Four organic and chemical sources of potassium viz., K
= 100%
vermicompost, K
2
= 50% MoP + 50% vermicompost, K
= 50% MoP + 50% mushroom
spent compost and K
4
3
= 50% vermicompost + 50% mushroom spent compost and Factor
B: Three seedling ages viz., S
1
= 20 days age of seedlings, S
= 25 days age of seedlings
and S
3
2
= 30 days age of seedlings. The experiment was laid out in a Randomized
Complete Block Design (RCBD) with three replications. Data were recorded on growth,
yield components and yield of kohlrabi and significant variation was observed for most
of the studied characters. Under this investigation, it was revealed that the highest yield
(38.44 t ha
-1
) with net return (Tk. 200,800) and BCR (2.09) was obtained from the
treatment combination K
2
S
(50% MoP + 50% vermicompost + 25 days age of
seedlings). On the other hand, the lowest yield (19.78 t ha
2
-1
) with net return (Tk.
55,000) and BCR (1.39) was obtained from the treatment combination of K
(100%
vermicompost + 20 days age of seedlings). So, economic analysis revealed that the K
treatment combination appeared to be best for achieving the higher growth, yield and
economic benefit of kohlrabi.
