Growth and Yield of Kohlrabi as Influenced by Organic and Chemical Sources of Potassium and Age of Seedlings
Journal of Agriculture and Ecology Research International,
The experiment was carried out at the “Horticulture Farm” of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during November 2019 to February 2021 to study the effect of different organic and chemical sources of potassium and age of seedlings on growth and yield of kohlrabi. The experiment consisted of two factors. Factor A: Four organic and chemical sources of potassium viz., K1= 100% vermicompost, K2= 50% MoP + 50% vermicompost, K3= 50% MoP + 50% mushroom spent compost and K4= 50% vermicompost + 50% mushroom spent compost and Factor B: Three seedling ages viz., S1= 20 days age of seedlings, S2= 25 days age of seedlings and S3= 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) was obtained from the treatment combination K2S2 (50% MoP + 50% vermicompost + 25 days age of seedlings). On the other hand, the lowest yield (19.78 t) was obtained from the treatment combination of K1S1 (100% vermicompost + 20 days age of seedlings). So, it revealed that the K2S2 treatment combination appeared to be best for achieving the higher growth and yield of kohlrabi.
