An Efficacy of Plant Growth Substances on Vegetative Growth Traits and Fruiting Behaviour in Strawberry c.v. Winter Down under Open Condition

An experiment has been undertaken in the year of 2021 and 2022, to investigate about an efficacy of plant growth substances on vegetative growth traits and fruiting behaviour in strawberry c.v. Winter Down under open condition. This research work has been done under Randomized Block Design (RBD) having thirteen treatments viz. GA 3 50, 75 and 100 ppm, promalin concentration such as 4, 6 and 8 ppm, GA 4+7 with10,15 and 20 ppm, NAA at 15, 20, 25 ppm and control (water spray) and every treatment was replicated three times. Result showed the strawberry plants treated by 20 ppm GA 4+7 fourteen days before blooming positively find out the highest plant height (33.33 cm) , leaf area (238.59 cm2), number of flower plant-1(30.76) as compared to control. Plant treated by 8 ppm promalin has also revealed positive results as compared with water spray. Therefore, this has been concluded that the application of 20 ppm GA 4+7 applied fourteen days before blooming is significant for vegetative growth traits and fruiting of Winter Down cultivar of strawberry.
