An experiment was conducted at Indian Institute of Horticultural Sciences, Bangalore to study the effect of growth regulation through spacing and pruning on yield and quality of tomato hybrids (Lychopersicon esculentum Mill.) grown under control conditions. The results of present investigation revealed that tomato variety Sun 7611 (V2) recorded the higher (7.42, 7.90, 4.63 and 1.85) number of flowers per cluster at all the stages of crop growth and differed significantly from Arka Abhijith (V1). Where in pruning methods single stem (P1) gave higher (6.74 and 7.09) number of flowers per cluster at 30 and 60 days after transplanting, which were significantly different from P2 (double stem). Tomato grown on single-stem resulted in higher individual fruit weight (77.04 g) than double stemmed plants. Maximum yield of 2.23 kg/plant and 129.4 tonnes per hectare was recorded in plants having two stemmed plant, and the yield of 1.96 kg per plant and 114.38 tons per hectare was obtained from single-stemmed plants. Plants wider spacing gave the highest fruit weight (79.15 g) followed by medium spacing plants (73.92 g) and the least was recorded in closely spacing plants (69.07 g). Fruit yield per plant was significantly reduced under closer plant spacing (1.8 kg) and increased as spacing were increased.Keywords

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
