Description The present investigation was carried out at Centre for Protected Cultivation Technology (CPCT) farm at Indian Agricultural Research Institute (IARI), New Delhi during summer and kharif seasons 2011 under naturally ventilated poly house, insect proof net house and open field conditions. The seed parent and pollen parent were grown in 3:1 ratio. Water and nutrients were provided through drip fertigation in all three conditions. Significantly higher vine length and number of leaf node were observed at 30 and 45 days after transplanting under naturally ventilated poly house compared to insect proof net house and open field conditions. In all three growing conditions, vine length and number of leaf node were significantly more in kharif season compared to summer season. Number of fruit develop to maturity was significantly more in kharif (2.15) than summer (1.90). The fruit weight, fruit length and fruit width were also significantly higher under naturally ventilated poly house and insect proof net house compared to open field in both of the seasons. The number of seeds per fruit was significantly higher in insect proof net house (204.15) and naturally ventilated poly house (188.35) as compared to open condition (126.05). The seed yield per fruit, seed yield per plant and seed yield per 1000m2 were significantly higher in kharif season as compared to summer. Whereas higher seed yield was recorded in insect proof net house followed by naturally ventilated poly house and open field condition. The seed quality attributes viz., germination percentage, seedling length, seedling dry weight, vigour index I and II and seed moisture content immediately after harvest were also significantly superior in naturally ventilated poly house and insect proof net house in comparison to open field conditions. The cost to benefit ratio is higher in insect proof net house (1:2.25) followed by open condition (1:1.12) naturally ventilated poly house (1:0.37).
