520			_a ABSTRACT MENOR, ALLAN N. 2019. Response of Cucumber (Cucumis sativus L.) to the Application Gibberellic Acid. Undergraduate Thesis, College of Agriculture, Food and Sustainable Development. Mariano Marcos State University, City of Batac, Ilocos Norte. 52pp Adviser: Mr. Raymund Julius G. Rosales. The study involved a field experiment from January to March 2019 in a rainfed lowland area at Brgy. 7 Alejo Malasig. Vintar, Ilocos Norte. Generally, the study was conducted to determine the effectiveness of GA3 and verified the results of the study of Tolentino (2018). Specifically, it aimed to evaluate the growth and yield performance of cucumber, identify the best concentration of GAZ that gives higher yield of cucumber, determine the effect of GA, on seeds of cucumber, and determine the production economics of growing cucumber using different concentrations of GA. Four treatments (no GA3, 10 ppm, 25 ppm, and 50 ppm) were laid out in Randomized Complete Block Design with four replications. Plot size of 9.9m was used with a distance of a meter between plots and blocks. Commercial hybrid seeds of cucumber were used and sown at 1.1 m between rows and 0.60 m between hills. Spraying of GA3 was done at 20, 40, and 60 days after planting (DAP). Growth parameters such as days to emergence of male and female flowers, number of staminate and pistillate, days to maturity; the yield and yield components such as number of fruits per hill, fruit yield per hill, number of fruits per kilo, fruit length and diameter, fruit weight, number of seeds per fruit, yield per hectare, shelf life. No significant effect was observed on all growth parameters except the maturity from planting to first harvesting. The yield and its components were not also affected by GA: An application of 50 ppm GA induced late maturity of plants but the lower concentration (25 ppm) caused the crop to mature as early as 17 days from flowering which was comparable to plants with no application.
