STUDIES ON THE EFFECT OF DIFFERENT PLANT GROWTH REGULATORS ON GROWTH, YIELD AND QUALITY ATTRIBUTES OF TOMATO (Solanum lycopersicum L.) CV. KASHI AMRIT

Abstract

The present investigation was undertaken to “studies on the effect of different plant growth regulators on growth and yield attributes of tomato (Solanum lycopersicum L.) cv. Kashi Amrit” Horticulture cum instructional farm in the Experimental field of AICRP on vegetable crops, College of Agriculture, IGKV, Raipur (C.G), during 2018-19. The experiment was laid out in Completely Randomized Design having often treatment and three replication. All growth, phonological as well as yield and quality parameters was found to be significantly superior at different concentration of GA3, NAA and Kinetin as compare to control treatment. The data clearly showed that the maximum plant height (84.54cm), number of leaves per plant (35.67), number of branches in per plant (16.34), plant girth (4.64cm) at 90 days after transplanting, minimum days required to first flowering (25.67), days to first fruiting (32.34) and minimum days to maturity (63.33), maximum no. of fruits per plant (52.67), average fruit weight(1500g), fruit length(4.96cm), fruit diameter(5.16cm), yield per plot(33kg), yield per ha.(555.55qt) was reported in treatment where plant has been sprayed with GA3 (50ppm).
