Guava (Psidum guajava L) is one of the most promising fruit crops of India and is considered to be one of the exquisite nutritionally valuable and remunerative crops. Its cultivation is done on the commercial scale due to three fruiting seasons viz., Ambebahar, Mrigbahar and Hasthbahar. Continuous bearing results in reduction of yield with small size fruits. The heaviest flowering was observed in rainy season guava crop, but the fruits of this season are rough, insipid in taste, poor in quality, less nutritive and are heavily attacked by many insects, pests, and diseases. In order to overcome this problem and to force a full crop during winter season, pruning should be done during February alongwith spraying of NAA 500ppm. Therefore, these studies were conducted to increase the winter season crop of guava conducted at Advanced Centre for Horticulture Research, SKUAST-J, Udheywalla, Jammu during the year of 2023-2024. The pruning was done at different levels and the results revealed that the maximum optimum optimum plant height (2.95 m), Plant spread (E-W) (2.98 m), plant spread (N-S) (2.96 m), plant volume (5.85 m3), girth of primary branches (2.17 cm), number of leaves per shoot (48.43) and number of leaves per tertiary shoots (15.69), were recorded in treatment – 4 comprising of 50 percent pruning of guava trees similarly, maximum leaf area (62.23), petiole length (0.66 cm), leaf chlorophyll content (53.80 SPAD), tertiary shoot girth (1.61 cm), number of flowers for per plant (243.31), fruit set% (74.10%), fruit length (6.22 cm), fruit width (5.03 cm), fruit weight (162.26 gm), fruit volume (166.06 cc), number of fruits per plant (129.88) and highest yield (21.08 kg/plant), total soluble solid (14.15° Brix), ascorbic acid (229.99 mg/100gm per pulp), pulp percentage (97.71%), pH of juice (5.08), total sugars (9.55%), reducing sugars (5.42%), non-reducing sugars (4.13%), pectin (1.86%), available nitrogen (242.76 kg ha-1), available phosphorus (17.23 kg ha-1) and available potassium (1424.27 kg ha-1) was also found best with 50% pruning intensity in guava trees during February –March under north Indian conditions of India. In general, the 50% pruning intensity was found best for enhancing vegetative growth and fruit quality of winter season guava under Jammu sub-tropics.
