A poly-cum-shade net house of 9.2 m x 5 m x 3.6 m covered with 50% green shade net on periphery and roof covered with 200 UVS PE sheets was developed for capsicum cultivation. Environmental parameters like temperature, relative humidity, and light intensity and crop parameters such as plant height, number of leaves, number of fruits, crop yield were recorded during the experimentation. Inside the structure temperature decreased around 1–2°C and 4–5°C while Rh increased 5.5–2.1% and 3.7–3.0% during winter and summer season, respectively as compared to open field condition. The light intensity during winter was varied from 1520 to 41,590 lux inside the structure and 2450 to 73,560 lux in open field whereas for summer season, it was varied from 4720 to 22,090 lux and 10,110 to 91,170 lux for inside and open field respectively. The crop parameters such as plant height (84 cm), number of fruits per plant (39), crop yield (44.6 t/ha) were found maximum for 0.8 IW/CPE while number of leaves per plant (105) was recorded maximum for 1.0 IW/CPE. Net profit for capsicum cultivation in poly-cum-shade net house was estimated at Rs. 4,01,870 per hectare with 1.32 benefit-cost ratio.
