Effect of plant growth regulators on growth and yield attributes of tomato (Solanum lycopersicom Mill.)

An experiment was conducted at Horticulture Garden, Department of Horticulture, Chandra Shekhar Azad University of Agriculture & Technology, Kanpur during the Kharif season of 2016-2017. The experiment was laid out in Randomized Block Design with ten treatments in three replication consist of three levels of each growth regulator i.e. GA3 at 10, 20, 30 ppm, NAA at 20, 30, 40 ppm and 2,4-D at 2.5, 5.0, 7.5 ppm. Maximum plant height (96.18 cm), maximum number of primary and secondary branches, and maximum fruit per plant (46.06), fruit yield per plant (1320.0 g) and fruit yield per hectare (52.5 t/ha) was observed with the application of GA3 at 30 ppm. However, maximum number of flowers was obtained with the application of 2,4-D (5 ppm). The results indicated that the use of GA3 at specific concentration of 30 ppm, considerably increased the weight of fruit and significantly increased total yield up to 52.5 t/h.
