Online published on 2 April, 2024. Abstract Research was conducted on the "Allison" cultivar of kiwifruit that were ten years old and had been grown on their own roots, in situ, and grafted vines. Girdling was carried in these plants at different planting intensities. The experimental vines were subjected to four different girdling treatments viz. no girdling, 25% girdling, 50% girdling, and 100% girdling. Data generated revealed that grafted kiwifruit plants whose trunks were girdled up to 25% by removing 2 mm of bark in the last week of March resulted in early blooming, and had higher leaf carbohydrates (4.43 %), fruit length (67.10 mm), and yield (18.03 tonnes/ha). Also, there was notable increase in the amount of nitrogen (2.45%), phosphorus (0.29%), and (2.42%) that was accumulated by the leaves. The correlation study revealed that yield had a positive relationship with leaf area, leaf carbohydrates, and fruit length, but did not have a significant positive relationship with leaf macronutrients.
