PERFORMANCE OF GRAFTING TECHNIQUES IN MANGO VARIETIES

Abstract

The study was conducted in the Horticulture farm of Sher-e-Bangla Agricultural University, Dhaka during the period from June to December 2019 to assess the performance of different grafting techniques and scion from different mango varieties on young and adult mango tree. This experiment consisted of two factors: Factor A: Grafting techniques (G 1 - Cleft grafting, G 2 - Veneer grafting, G 3 - Whip grafting) and Factor B: Scion from different mango varieties (S 1 - Fazli, S 2 - Langda, S 3 - Himsagor, S 4 - Namdokmai). The two factors experiment was laid out in Randomized Completely Block Design with three replications. Results exposed that different combinations of different grafting techniques and scion from different mango varieties had a significant effect on success of grafting, Significant effect were found in number of leaf production on scion part, circumference and height of scion part on both young and adult mango tree. In case of grafting on young mango plant S 2 and G 1 gave highest growth in scion and rootstock circumference, height of scion and number of leaves per scion which is reflected from the results of S 2 G 1 combination. But the highest success rate was found from S 1 (73%) and G 1 (70%). Considering combined effect treatment combination S 1 G 1

showed the best success result (80%). Regarding grafting on adult mango trees the highest grafting success rate was noted from S 4 (62.22%) and G 2 (68%) while treatment combination S 4 G 2 gave the best result (80%). On the other hand, S 3 (53.33%) and G 1

(48.13%) treatment combination gave the lowest success and it was only 53.33%.
