Abstract
The present investigations “Studies on the effect of pruning intensities and time on winter guava production in cv. Allahabad Safeda under high density planting” were carried out at the experimental farm of Department of Fruit Science, College of Horticulture and Forestry Neri, Hamirpur (H.P.), during the year 2020-2021. The research trial was conducted on four years old guava plants, planted at 2 x 2 m spacing. The plants were subjected to three pruning intensities viz., 10, 15 and 20 cm shoot pruning from the terminal portion at different times i.e., 1st and 3rd week of May, June and July. Among the different pruning times, severely pruned plants (20 cm pruning from the shoot tip) produced best results with respect to shoot length (34.27 cm) and leaf area (59.19 cm2). Shoot pruning done at 10 cm from the terminal portion was found better for improving reproductive characteristics of guava plants i.e., minimum time taken for flower emergence (43.22), fruit set (32.24 %) and fruit yield (7.29 kg). Severe pruning (20 cm from the shoot tip) produced comparatively superior quality fruits. Among different pruning times, plant pruned during 1st week of May effectively improved vegetative, reproductive and qualitative characteristics of the guava fruits. The study clearly revealed that light pruning intensity (10 cm shoot pruning from the terminal portion) performed during 1st week of May was found effective in improving fruit set (43.73%) and fruit yield (8.80 kg/plant) whereas, 20 cm shoot pruning performed during 1st week of May was found effective in improving physical and qualitative attributes of fruits i.e., fruit weight (156.12 g), fruit volume (162.01 cm3), fruit length (6.51 cm), TSS (9.63 0B), ascorbic acid (182.55 mg/100g).
