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).

Summary
There are different ways and means to achieve this target, e.g., bringing additional area under vegetable crops, using hybrid seeds, use of improved agro-techniques. Another potential approach is perfection and promotion of protected cultivation of vegetables [2]. During extreme conditions of weather, these high value vegetables can be well cultivated under protected cultivation structures year-round. Research results have shown that by adopting protected cultivation, productivity of high value vegetable crops can be increased by 3 to 5 times as compared to open environment. Polyhouse, shade net house & low tunnels are the different types of protected cultivation structures commonly adopted by the farmers of developed country
