Abstract:
The present study was undertaken with an aim to investigate the “Effect of organic nutrient
sources on growth and yield of kohlrabi plants”. The experiment was conducted during the
period from November 2020 to February 2021 at Horticulture farm of Sher-e-Bangla
Agricultural University, Dhaka. The experiment was laid out in Complete Randomized
Design (CRD). The experiment consisted of nine treatments viz., N
0
:
Cowdung (10 t/ha), N
2
: Vermicompost (4 t/ha), N
3
: Vermicompost (4 t/ha) (50%) +
Biochar (4 t/ha) (50%), N
4
: Control, N
1
: Vermicompost (4 t/ha) (70%) + Biochar (4 t/ha) (30%), N
5
:
Kitchen compost (5 t/ha) (50%) + Vermicompost (4 t/ha) (20%) + Trichoderma (5 t/ha)
(30%), N
6
: Mushroom Compost (5 t/ha) (50%) + Trichoderma (5 t/ha) (50%), N
7
: Kitchen
compost (5 t/ha), N
8
: Mushroom Compost (5 t/ha). Total numbers of unit plots were twenty
seven. The unit plot size was 1.2 m x 0.9 m. The results indicate that plant height, number
of leaf, leaf length, leaf breadth and yield were influenced significantly among the
treatments. With application of organic nutrient sources the maximum yield per plot was
obtained from N
5
treatment (3.86 kg) while the minimum yield per plot (2.26 kg) was
obtained from the control treatment N
0
and likewise maximum yield per hectare (35.77 t)
was observed in treatment (N
5
) while the minimum yield per hectare (20.95 t) was obtained
from the control treatment (N
0
). Therefore, it can be concluded that applying N
5
treatment
was best for kohlrabi production.
