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 . GA3 at 10, 20, 30 ppm, NAA at 20, 30, 40 ppm and 2,4-D at , , ppm. Maximum plant height ( cm), maximum number of primary and secondary branches, and maximum fruit per plant (), fruit yield per plant ( g) and fruit yield per hectare ( 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 t/h. | Effect of plant growth regulators on growth and yield attributes of tomato (Solanum lycopersicom Mill.)
