Abstract
The present investigation entitled “Studies on the effect of summer pruning on cropping behaviour in low chill peaches (Prunus persica L. Batsch.)” was carried out in the Experimental orchard of Department of Fruit Science, College of Horticulture and Forestry, Neri, Hamirpur (HP) during the year 2018 and 2019. The studies were conducted in two experiments on 3-year-old low chill peaches cvs. Early Grande, Florida Prince and Shan-i-Punjab, planted at a spacing of 2 x 2 m 2 and trained to Pillar system. In the first experiment, effect of summer pruning intensities viz., T 1 (control), T 2 (20% summer pruning+ WP), T 3 (30% summer pruning+ WP), T 4 (40% summer pruning+ WP), T 5 (50% summer pruning+ WP), T 6 (60% summer pruning+ WP) and T 7 (standard winter pruning) on cropping behaviour were studied in peach cv. Early Grande. Whereas, In the second experiment, summer pruning treatments at different times viz., T 1 (control), T 2 (25% summer pruning on July10 th +WP), T(25% summer pruning on July 20 th 3 +WP), T 4 (25% summer pruning on July 30 th +WP), T(25% summer pruning on August 10 th 5 +WP) and T 6 (standard winter pruning) were tried in peach cvs. Florida Prince and Shan-i-Punjab to see the effect on cropping behaviour. During the present investigations, the results obtained showed that among different pruning intensities, the best results in terms of vegetative, reproductive and qualitative characteristics were obtained with severest pruning intensity i.e. T 6 (60% Summer Pruning + WP). Although, the fruit yield was slightly lower, but quality of fruits was much superior than other treatments. In case of summer pruning performed at different timings, the best results in terms of vegetative, reproductive and qualitative parameters were recorded with earliest summer pruning i.e. T 2 (25% summer pruning on July 10 th + WP) treatment. However, among cultivars, Florida Prince performed better than Shan-i-Punjab.
