Description of innovation
Fallen sapota plants are used for grafting in this alternate method. In fallen plants, scion branches of pencil thickness remain nearer to around helping into non-hanging of rootstock upon the tree. Hanging of a rootstock (in a mud ball) on a large and high tree is not only labour intensive, but also costly affair. Grafting in fallen tree is easy and around 2,000 to 2,500 grafts can be prepared from a single plant per season. Observing the ease of making grafts, orchard growers have started felling sapota plant artificially/ mechanically by digging one side of the plant and by cutting few roots. After felling tree, rootstock of khimi seedlings (in mud ball) are placed on the soil by the side of the pencil thickness branches of sapota mother-plant. Mud ball of khimi seedlings are placed within the soil by making small holes. In this way, a grafter can make 250 to 300 graft unions in a day. After removal of graft unions, mother plants are erected, properly nourished and then again made to fall in the opposite side to complete cycle of two grafting in a year.

Practical utility of innovation
In this method, 4200 grafts per year can be produced with a profit of Rs 16,110 and 2.59 B:C ratio. In non-grafted plants, profit is only Rs 850 per year as the cost of seedling is 50 paisa against Rs 6.25 in the grafted seedling. This technique was first applied in Srikrishnapur village of the district by the group of farmers and now it is practised by the farmers of Amtala-Bishnupur region–the main nursery area of the district.
