Abstract

A field trial was conduct at Horticulture Research Center, Patharchatta, Pantnagar, Department of Horticulture, GBPUAT, Pantnagar india during 2017-2018 to evaluate the effect of fruit thinning on growth, yield and quality of rainy season crop of guava cv. pant prabhat. There were five different fruit thinning treatments viz. 10%, 20%, 30%, 40% 50% fruit thinning and one control (without thinning) planted in single hedge row system (4x8m). The treatment T5 (50% fruit thinning) gave maximum increase in plant height, spread, fruit diameter and plant volume whereas, lowest increment of growth was found in case of treatment T6 control (without thinning treatment). In case of total number of fruits per plant and yield per plant were found maximum in T6 control (No fruit thinning) but better quality and bigger size, fruits was found with the thinning of 50% fruit. From the study it can be concluded that for getting better quality and bigger size, fruits in rainy season crop of guava under single hedge row planting in tarai condition of Uttarakhand 50% fruit thinning can be recommend in first week of June.
