Effect of Plant Growth Regulators on Growth, Yield and Quality of Cucumber (Cucumis sativus L.)

Abstract

An experiment entitled Effect of plant growth regulators on growth, yield and quality of cucumber (Cucumis sativus L.) was conducted at Horticulture Research Field, Department of Horticulture, Naini Agricultural Institute, SHUATS, Prayagraj during July-October, 2022. The experiment was laid out in Randomized Block Design with thirteen treatments and replicated thrice. The growth regulators were sprayed at two true leaf stage and four true leaf stages. Data was collected from vine length, days to first appearance of male flowers, days to first appearance of female flowers, days to 50% pistillate flowers, days to first harvest, length of fruit, fruit weight, fruit diameter, number of fruits per plant, average yield per plant, yield per hectare, Total Soluble Solids, and vitamin C and analyzed using analysis of variance. Results showed that GA3 175 ppm sprayed at 2 and 4 true leaf stage of cucumber hybrid TMCU-1107 was superior in terms of vine length (119.56cm), days to first appearance of male flowers (32.16), days to first appearance of female flowers (38.2), days to 50% pistillate flowers (41.2),  days to first harvest (52.41), fruit weight (255.86g), length of the fruit (17.27cm), fruit diameter (4.82cm), number of fruits per plant (12.16), average yield per plant (3117.11g), yield per hectare (27.7t/ha), TSS (4.23 0Brix), Vitamin C (2.05mg/100g).
