Abstract
A field experiment was carried out at the department of horticulture, Hi-tech
Horticulture Unit, Saidapur Farm, University of Agricultural Sciences Dharwad
during 2009-10 to study the performance of tomato hybrids under shade house
condition. Among the vegetative parameters STH-801 tomato recorded higher plant
height (309.03 cm), maximum number of branches per plant (8.17) whereas, STH-801
hybrid recoded more number leaves (85.67/plant). Hybrid STH-901 recorded longer
internodes (6.96 cm), higher leaf width (5.82 cm) and longer leaves (15.40 cm) and
STH-39 recoded thick stem (1.78 cm).
Plants trained under single stem recorded higher plant height (270.08 cm),
stem girth (1.75 cm ), number of branches per plant (7.78), intermodal length (6.75
cm), leaf length (15.10 cm), leaf area (77.06 cm2) compared to the plants trained with
two stems. Number of leaves per plant (82.80) was found maximum in plants trained
under double stem.
Days to fifty per cent flowering, days taken from flowering to fruit
development were not influenced by training. Among the hybrids, STH-801 recorded
higher number of cluster per plant (12.15), number of fruit per cluster (7.75) and
percent fruit set (93.17). STH-801 recorded the highest yield per plant (6.52 kg), yield
per square meter (15.68 kg) and number of seeds per fruit (141.50). Whereas, STH-39
recorded the highest average fruit weight (115.50 g), average fruit diameter (6.30 cm)
and average fruit volume (157.00 cc).
Plants with double stem recorded increased yield per plant, yield per square
meter (6.30, 15.36 kg respectively). Plants with single stem recorded highest average
fruit weight, average fruit diameter, average fruit volume and number of seeds per
fruit (105.50 g, 5.59 cm, 143 cc, 115 respectively). STH-801 tomato juice possessed
higher amount of TSS and pH (5.47 0B, 6.20 respectively). The study revealed that
hybrid STH-801 performed best with yield of 6.52 kg per plant and STH-801 on
double stem training system was superior of all the other treatment combinations
