Abstract

The aim of this experiment was to examine the effects of grafting time on the success and survivability of different varieties of mango. The study comprises nine grafting time, viz., 10, 20, 30 March, 10, 20, 30 April, 10, 20 and 30 May, 2009 and thirteen different varieties of mango viz. BAU Aam–1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, and BAU Aam–13 were used. The experiment carried out in the Randomized Complete Block Design with three replications. The maximum time required to bud breaking (12.14 days) was noted in 10 March grafted plants while the minimum (9.44 days) was obtained in the 30 April grafted plants. The highest percentages of graft success and survivability were recorded on 20 April (96.87% and 90.62%) and the lowest was observed in 10 March grafting (96.05% and 88.64%). The minimum time (9.46 days) required for bud breaking was found in BAU Aam–6 and the maximum (11.64 days) and was required in BAU Aam–10 followed by BAU Aam–13 (11.64days) and BAU Aam–12 (11.57days). The highest graft success and survivability (97.3% and 96.23%) were observed in BAU Aam–6 and the lowest (95.66% and 86.42%) were in BAU Aam–13. In case of combined effect, the minimum time (7.73 days) was required in BAU Aam–6 in 30 April grafting while the maximum time (13.06 days) required for bud breaking was found in BAU Aam –10 when the grafting operation was done on 10 March. Grafting operation done on 10 April and 20 April with the scion of BAU Aam–1 gave the highest success (97.64%) and the lowest (94.81%) was on 10 March with BAU Aam–7. Grafting operation done on 10 April and 20 April with the scion of BAU Aam–6 gave the highest graft survivability (96.56%) and the lowest (71.66%) was on 10 March with BAU Aam–11.
