The experimental results revealed that, In respect of growth parameters significantly minimum days (16.95 days) required for sprouting of grafts and maximum graft success per centage (93.33%) were recorded in grafts of variety NA-7. Similarly the maximum values of growth parameters viz., sprout height (42.18 cm), number of leaves (44.69), leaf area (46.20 cm²), length of scion stick (42.18) and number of branches of the sprouted scion (4.8) were observed in grafts of variety Chakaiya. A favourable stionic ratio was noticed in grafts of varietie NA-10. The maximum survival percentage (93.33%) was recorded in grafts of varietis NA-7.

In respect of covering material, the transparent plastic bag of 2”×9” required lowest number of days for sprouting (16.90 days) and resulted in maximum leaf area (35.84), number of leaves (44.20), girth of rootstock (7.37), girth of the scion (7.30), length of scion stick (41.90) and number of branches (4.75). The interaction effect of variety and covering material on graft success observed significantly in variety NA-7 with transparent plastic bag 2”×9” which taken the minimum number of days for sprouting of shoots & recorded the maximum success per centage. The overall results showed that, the variety NA-7 with transparent plastic bag of 4”×9” was found to be most effective for in-situ grafting in aonla for Marathwada region.
