Effect of zinc sulphate and gibberellic acid on physical characters and yield attributes of winter season guava (Psidium guajava L.) CV. Allahabad Safeda

Abstract

The present investigation was carried out at the Effect of Zinc sulphate and Gibberellic acid on Physical characters and yield 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 vegetative growth and yield attributing characters of guava fruits. The maximum fruit size, fruit weight, fruit volume and specific gravity were recorded with foliar application of 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 vegetative growth and yield attributing characters of guava.
