Abstract: The present investigation was carried out at the Effect of Zinc sulphate and Gibberellic acid on Chemical attributes of Winter Season Guava (Psidium guajava L.) cv. Allahabad Safeda” at the Main Experiment Station, Department of Horticulture, Narendra Deva University of Agriculture & Technology, Narendra Nagar (Kumarganj), Faizabad (U.P.) during the year 2015-2016. The experiment was conducted in Randomized Block Design with seven treatments and replicated in three times, considering one plant as a unit. The observations were recorded for chemicals attributing characters of guava fruits. The maximum fruit size (6.30), weight (110.21), volume (110.35) and diameter (6.87) were recorded with foliar application of GA₃@150ppm. Better quality fruits with respect to highest specific gravity (0.998) were recorded with GA₃@150ppm. The fruit yield was also recorded maximum with the combined spray of GA₃@150ppm. Overall it can be concluded that application of GA₃@150ppm judged the best for higher fruit yield, production and better fruit quality of guava.
