Abstract
A field experiment was conducted at Instructional Farm, College of
Agriculture, Jodhpur to assess the “Effect of gibberellic acid, 4-CPA, and NAA on
growth, yield and quality of tomato (Solanum lycopersicum L.) cv. Ansal” during
Rabi, 2021-22. The experiment comprised of ten treatments consisting of three levels
(25, 50 and 75 ppm) each of GA3, 4-CPA and NAA along with control. The
experiment was laid out in a randomized block design with three replications. The
result revealed that all the growth, yield attributes and quality parameters were
influenced significantly by different levels of GA3, 4-CPA and NAA. Among the
different levels of growth regulators, maximum plant height (47.2 cm, 61.3 cm and
80.9 cm at 45 DAT, 60 DAT and final harvest, respectively), number of
branches/plant (19.4), leaf area (30.6 cm2), TSS (5.41 °Brix) and ascorbic acid (22.8
mg/100 g) was recorded with GA3@75 ppm, whereas acidity (0.54 %) was recorded
with GA3@25 ppm. The maximum fruit length (6.7 cm), fruit diameter (7.2 cm), and
fruit firmness (2.6 kg/cm2) were found with 4-CPA@75 ppm. The maximum
chlorophyll content (42.0, 48.0, 44.0 SPAD at 45, 60 DAT and at final harvest,
respectively), number of fruit clusters/plant (12.0), number of flowers/cluster (5.4),
number of fruits/cluster (3.2), number of fruits/plant (38.1), fruit set (59.7 %), fruit
weight (84.3 g), fruit yield/plant (2.6 kg), fruit yield/ha (29.7 t), lycopene content (6.5
mg/100 g), net returns (480,447 `/ha) and B:C ratio (4.26:1) was observed with
NAA@75 ppm.
