Effect of Different Shade House on Quality Seedling Raising of High Value Vegetables

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 o f 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%) w ere 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).
