Manipulation through grafting and pruning for dwarf shape of BARI released mango variety

This study evaluates the effects of various grafting and pruning techniques on the growth and fruit quality of the BARI mango variety, conducted at the Regional Horticulture Research Station in Chapainawabganj from 2019 to 2023. Using a Randomized Complete Block Design (RCBD) with three replications, seven treatments were implemented, including normal grafting and multiple grafting methods, alongside stem cutting. Significant variations were observed in plant growth metrics. Treatment 1 (T₁) achieved a maximum height of 4 m and a base girth of 34.5 cm, yielding 11.1 kg of fruit from 30 fruits, despite having the fewest branches (7.5). In contrast, Treatment 3 (T₃) reached a height of 2.25 m with a base girth of 23 cm, producing 12.32 kg from 28 fruits, but exhibited the highest number of branches (12.5). T₃ also resulted in the largest average fruit weight at 440.2 g, while Treatment 7 (T₇) recorded the highest edible portion at 81%. Further analysis revealed that T₃ and Treatment 2 (T₂) had the highest Total Soluble Solids (TSS) percentages (21%), indicating superior fruit sweetness. These results underscore the importance of specific grafting and pruning strategies in optimizing both the structural integrity and fruiting potential of the BARI mango variety. The findings highlight the potential for implementing high-density planting practices, enhancing productivity, and contributing to sustainable agricultural systems.
