The experiment was conducted at Agril. Research Station, Palghar, Dist. Thane, Maharashtra state to evaluate the yield of different capsicum genotypes grown under different growing conditions viz., polyhouse and open field. The plant growth and average fruit weight of capsicum was significantly superior in protected conditions (polyhouse) in comparison to the open field conditions. Under control conditions, Manhattan variety recorded maximum plant height (79.28 cm) followed by California Wonder. However, in open conditions, California Wonder recorded significantly maximum height (52.78 cm) followed in Aishwarya. Under both conditions, the growth of Bomby hybrid was comparatively slow. Under polyhouse conditions, the maximum fruit weight (77.86 gm) was reported in Orobelle hybrid followed by Manhattan while remaining were at par to each other. Under open field conditions, Manhattan recorded maximum fruit weight which was at par with California Wonder. Under polyhouse conditions, Orobelle recorded maximum increase (44.03 per cent) in the fruit size compared to open conditions. The fruit yield per plant was recorded maximum (2.369 kg plant-1) by California Wonder under polyhouse which was followed by Orobelle. As both growing conditions compared, the maximum increased yield was recorded Orobelle (41.22 per cent) followed by California Wonder (34.76 per cent), Aishwarya (31.77 per cent), that means these varieties/hybrids might be sensitive for environmental conditions.
