The undercover tomato trial was conducted at Indian Institute of Horticultural Sciences, Bangalore. This study was conducted to determine the response of semi-determinate and indeterminate hybrids of tomato to pruning and spacing grown under cover. The results indicated that the plant height was the highest in closer spacing at 30 (92.58 cm) 60 (135.98 cm), 90 (185.25 cm) days after planting and at final harvest (221.35 cm), whereas maximum leaf area (4045.92 cm2 and 5705.73 cm2) was observed in V2 at both first and last harvest. Maximum dry matter (35.31 to 38.48%) was observed in leaves followed by flowers and fruits stem and ischolar_main at first harvest. Maximum (45.18 to 50.4%) dry matter was observed in flower and fruits followed by stem, leave and ischolar_main at final harvest. Sun 7611 (V2) recorded the highest biomass accumulation (22.76 g, 77.81 g and 158.37 g) at vegetative phase, first harvest and at final harvest which was significantly different from Arka Abhijith (V1). Fruit set percentage was higher in Arka Abhijith (59.43%) than Sun 7611 (54.57) more number of flowers formed fruits in single stemmed plants (59.24%) compared to double stemmed plants (54.76%). Among spacing treatments per cent fruit set did not differ significantly. Further fruit yield was significantly higher in P2 (2.23 kg) than P1 (1.96 kg). Maximum fruit yield per plant was obtained in S3 (2.44 kg) followed by S2 (2.03 kg) and the least was observed in S1 (1.81 kg) which were significantly different. However, yield per hectare was significantly improved under closer spacing.Keywords
