A field experiment was conducted at the Instructional Farm, Department of Agronomy, Junagadh Agricultural University, Junagadh, during kharif 2015-16 with an aim to study the plant growth regulators [G0 (control), G1 (50 ppm GA3), G2 (50 ppm NAA) and G3 (500 ppm Cycocel)] on seed yield per plant, its components and seed parameters of tomato cv. Gujarat Tomato 3 (GT-3). One month old healthy seedlings were transplanted in the field. The experiment was laid out in field as per randomized block design (Factorial) with three replications. The characters viz., days to flowering, plant height (cm), number of branches per plant, number of fruit per plant, length of fruit (cm), diameter of fruit (cm), number of seeds per fruit, seed weight per fruit (g) and seed yield per plant (g) were recorded as field observations, while germination percentage, root length (cm), shoot length (cm), root fresh weight (g), shoot fresh weight (g), root dry weight (mg), shoot dry weight (mg), Vigour index-I and Vigour index-II were recorded in the laboratory of Department of Seed Science and Technology, College of Agriculture, Junagadh Agricultural University, Junagadh.
