Study on Effect of Plant Growth Regulators (PGR) and Training System on Growth and Yield of Cucumber

A field experiment was conducted during the Kharif season, in 2023 in the Horticulture research field, Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology And Sciences, Prayagraj, U.P, India. The experiment was laid out in a Randomized Block Design (RBD) with twenty treatments and replicated thrice with four cucumber varieties (TMCU-1107, TMCU-1125, TMCU-3112, SAIRA-934). The observations are vine length, days to first appearance of male flower in 50% plants, days to first appearance of female flower in 50% plants, days to first harvest, average fruit weight, fruit length, fruit diameter, number of fruits per plant, average yield per plant, and yield per hectare. The results showed that viz., vine length (155.53 cm), days to first appearance of male flower in 50% plants (32.73), days to first appearance of female flower in 50% plants (39.20), days to first harvest (52.07), average fruit weight (245.93 g), fruit length (15.67 cm), fruit diameter (4.41 cm), number of fruits per plant (12.73), average yield per plant (3.13 kg/plant), yield per hectare (34.77 t/ha), were recorded significantly highest by the application of GA3 – 30 ppm + NAA – 75 ppm + Single head system (Treatment 3) as compared to rest of the treatments.
