Introduction Mango can be propagated by stone grafting, veneer grafting, soft wood grafting, inarching and saddle grafting methods, However stone grafting is most popular and successful method of mango propagation. A Scion bud stick from desired cultivar of mango is grafted on local sprouted stone at copper red color leaves stages and the grafts become ready for planting in field within 10 to 12 months.

Stone / Seed Selection and Treatment
Fresh, Bold and heavy stones/seeds of local mango varieties should be collected before monsoon. Stones / Seeds are washed with clean water to remove pulp and dirt attached to seeds. Seeds are treated with copper oxy 3 grams per liter of water for 20 minutes to control seed borne diseases in nursery. Mango Stones / Seeds

Sowing of Seeds Land at nursery site should be sloppy and well drained. Raised beds in nursery should be prepared with 90 cm wide, 10 cm height and length as per the requirements or the slope. Mix the bed soil with well decomposed Farm Yard Manure mixed with Phorate 10 G gram for one Gunta to control soil borne pests. Sow the seeds 4 cm deep, water the beds & keep them weed free.

Planting in Polythene Bag
Select 250 gauge Polythene bag with size of 20 cm height and 15cm width. Make 4-6 holes at lower side of bag and fill up them with media prepared by mixing garden soil, farm yard manure and sand in 2:1:1 proportions. The seeds/ Stones are sown in such bags for germination and further grafting. Sowing Seed in Poly Bag Media filled Poly Bag
5
Selection of Root Stocks
Germination of stone/seed starts 3-4 weeks after sowing in soil. Healthy stem and copper colored leaves stage comes after 2 to 3 weeks after germination is the right condition for grafting Germinated stones Seedling for Grafting
6
Selection of Bud stick / Scion
Bud sticks or scion sticks with prominent apical bud from desired and healthy mother plants should be selected for grafting. Bud stick from previous years season growth should be selected and defoliated 7 to 10 days before being cut for grafting.
7
Method of Grafting Rootstocks are carefully uprooted from raised bed and the stem should be cut at 8 to 10 cm above the ground. Make a vertical cut 4 to 5 cm deep to stem of rootstock and similar length wedge shaped cut to bud stick. Insert the wedge shaped portion of bud stick into cut portion of rootstock and tie the common part of graft firmly with a polythene strip.

Care and Maintenance of Graft
Water the grafts regularly and keep in partial sunlight and spray the grafts with Chloropyriphos (Radar) 20 ml and Carbendazim (Bavistin) 10 gm per 10 lit of water at 15 days interval. Remove sprouted growth on root stock and inflorescence on bud stick immediately after emergence. Shift the grafts with pale green leaves in direct sunlight for hardening & stake it with bamboo stick. Remove the polythene strip when union is completely healed and formed.
