Effect of pruning intensity and time on yield and quality of guava cv. L-49

Abstract

The present investigation was conducted in the guava orchard of Department of Horticulture, Khalsa College, Amritsar during the year 2018–19 to study the effect of pruning intensity and time on yield and quality of winter guava cv. L-49. Different pruning levels and time of pruning viz., pruning of 10, 20 and 30 cm of apical shoots during 30th April, 15th May, 30th May and 15th June comprised the treatment combinations. The experiment was laid out in factorial randomized block design. The results of the study revealed that among the various pruning treatments the pruning of 30 cm of apical shoots on 15 May proved to be the best in increasing the yield and yield attributes in terms of number of fruits per tree and also fruit size, weight and yield. It also improved the fruit quality by increasing TSS, sugars, ascorbic acid and pectin content of guava fruits. Hence, the pruning of 30 cm of apical shoots during mid May can be recommended for commercial fruit production with enhanced yield and good quality in guava cv. L-49.
