Sex Modification and Yield of Cucumber (Cucumis sativus L.) as Influenced by Different Levels of Auxins and Gibberellins

The possibility of altering the inducing femaleness, yield and yield attributing characters was examined by using different levels of GA3 and NAA in cucumber cv. Pusa Uday. There were a total eight treatments of two growth regulators: GA310, GA3 20, GA3 30 ppm, NAA 50, NAA 100, NAA 150 ppm, GA3 20 + NAA 100 and Control (distilled water). The total eight treatments were laid out in a Randomized Block Design with 3 replications. Out of these, the combined dose of GA3 20 ppm + NAA 100 ppm was found significantly superior in terms of days to first flower formation, number of male and female flowers, sex ratio, number of fruits, length and width of fruit (cm) at alternate days, length and width of fruit (cm) at five days and yield (qha?1) as compared to control and other applied treatments during experimentation.
