Abstract
The field experiment was conducted on cucumber during spring-summer (March to June) season of 2022 and 2023 at Instructional Farm of The Neotia University, Sarisha, Diamond Harbour, West Bengal, India. Entirety six numbers of gibberellic acid treatments were comprises with five levels of GA3 viz., GA3@100ppm, GA3@200ppm, GA3@300ppm, GA3@400ppm and GA3@500ppm along with control treatment were assessed in randomized block design with three numbers of replications.The cucumber plant height was recorded for three sowing date intervals viz., 30 DAS, 60 DAS and 90 DAS, among these three sowing dates GA3@200 ppm was recorded highest plant height within the other treatments and the plant heights are 88.75cm, 234.30 cm and 272.18cm respectively for different sowing date intervals and lowest plant height was recorded in control treatment. It was also recorded from this experiment that is the number of male flower was recorded highest in GA3@400 ppm and highest number of female flower recoded in GA3@200 ppm (22.91).The most important and conclusion marking data was recorded in case of GA3@200 ppm treatment, because two parameters likely yield per plant (2348.84 g) and yield per hectare (281.86 qt/ha), collectively recorded highest in this treatment, on the other hand control treatment recorded least yield per plant (816.26 g) and yield per hectare (107.62 qt/ha).
