How to Graft Cashew-Nut Seedlings

Abstract

Cashew nut has previously been propagated in Kenya through seed. KALRO has introduced propagation through grafting to ensure crop uniformity and shorten time to maturity. The technique involves use of one month old rootstock which is grafted with improved cashew varieties using top-wedge grafting. Grafting on rootstocks older than one month do not succeed because of hardening of the rootstock cambium causing graft incompatibility. Grafting of young rootstocks produces seedlings ready for planting within 3 months.
