Abstract: An experiment was conducted from June 2012 tornJune 2013 in laterite soil of West Bengal, India to evaluate the influence ofrnshoot pruning in different times on flowering, fruit yield and quality of mangorncultivar ‘Mallika’ planted under triangular system of planting. The resultsrnrevealed that control plantsrnrecorded early flower initiation (17thrnJanuary) with peak period of flowering (2ndrnFebruary) and low (4.40 %) shoot mortality among the treatments. Shoot pruningrngave rise to slightly delay but more uniform flowering comparative to control.rnNumber of laterals produced per pruned shoots (5.2) was highest when pruningrnwas done on 15th July. The shoots pruned onrn15th June were recordedrnmaximum shoot length (45.5 cm), fruitedrnpanicles per plant-1 (66.3%), fruit yield perrnplant (89.2 kg) total soluble solids (26.10Brix)rnand vitamin C content (36.6 mg 100 ml-1rnjuice). Fruit weight was maximum (361 g) recorded from the plants pruned on 15thrnSeptember. Minimum acidity content was recorded on shoots pruned on 15thrnAugust. While no-pruning (control) had lowest fruit weight (281 g) and lower inrnyield (58.4 Kg) plant-1 with lowest total solublernsolids (22.90 Brix). Conclusively, the 15thrnJune shoot pruning for ‘Mallika’ could be recommended for restoring the maximumrnproduction and good quality fruits in triangular planting system of mango.
