ABSTRACT: An experiment was undertaken to identify suitable
shade house for different high value
vegetables during the winter season of 2019-20 at the research farm of Olericulture
Division, HRC, BARI, Gazipur.
The experiment was randomized complete
block design with 3 replications. Four vegetable
varieties viz., tomato (V1), brinjal (V2), capsicum (V3), broccoli (V4) and 4
shading treatments [1) UV stabilized polyethylene film with 60 mesh insect net along with
green shade net (T1); 2) UV
stabilized polyethylene film with 60 mesh insect net (T2); 3) 60 mesh insect net (T3)
and 4) Open
field (control) (T4)] were included in this study. Different vegetables
responded differently with the changes of
shade house irrespective of different
characters. Brinjal (V2) resulted in the maximum seed
germination (93.58%) with the lowest mortality (5.58%), in case of shading treatment, UV
stabilized polyethylene film with 60 mesh insect net along with green shade net
(T1) exhibited the maximum seed germination (94.83%) with lower mortality (3.33%).
In case of combined effect, maximum seed
germination (93.58%) and the lowest mortality (2.08%) were observed in V2T1. The tallest seedlings were produced in V3T1 at every growth
stage (15 days, 20 days, 25 days, 30 days). The maximum no. of leaves was
produced in V3T2. The minimum insect infestation was observed in V1T1, V1T2,
V2T1, V2T2, V3T1, V3T2, V4T1, V4T2 (0.67% at 15 days and 20 days).
