The present investigation was carried out at Horticulture Research Centre of G.B.P.U.A and T, Pantnagar to study the effect of girdling on yield and quality of litchi cv. Rose Scented. All the plants which were subjected to different level of girdling have more fruit set, fruit retention, yield and quality of fruits. However, girdling of main trunk + 50% of primary branches in which 3 mm wide and 3 mm deep ring of bark was removed found effective for obtaining maximum fruit yield (90 kg/tone) and good quality fruit (TSS _ 19°Brix, acidity- 0.62%, ascorbic acid- 29.86 mg/100 g pulp, total sugar-13.50% and TSS : acid ratio _ 30.93). Improvement in fruit yield and quality of litchi trees may be due to rapid translocation of photosynthates and minerals from other part of the plants to developing fruits and reduced flow of carbohydrates to the roots.
