Aniyamma Baby noticed something unusual while harvesting cashews in Kannur, Kerala: a branch touching the soil had formed additional roots. It remained healthy even after the original tree faced pest damage. Rather than treating the growth as an accident, she asked whether other mature trees could be encouraged to do the same.
An observation developed into a propagation method
Cashew growers must contend with ageing plantations, stem borers and storms. Replacing a damaged mature tree takes time before a new plant can bear fruit. Aniyamma experimented with lowering branches and encouraging roots to form where they met the ground. Her approach became known as the Multiple Rooting Propagation Method for Cashew, shaped by repeated field observation rather than a laboratory starting point.
The October 2026 issue describes the use of materials including soil, cow dung, stones and hollow areca nut stems. Additional root points may improve access to water and nutrients and provide support against some forms of damage. Results will depend on the condition of each tree and local growing practices; the method should be evaluated for a particular orchard before broad adoption.
Recognition for farmer-led research
The National Innovation Foundation documented and supported Aniyamma's work. The magazine reports evaluations by the ICAR Directorate of Cashew Research in Puttur and Kerala Agricultural University in 2020. It also records a National First Award at the National Biennial Grassroots Innovation Awards in 2023. Those steps helped move a farmer's observation into wider agricultural discussion.
The method also asks a practical question about farm economics. If an older productive tree can be strengthened, a grower may avoid some of the waiting involved in replacing it with a young plant. The October profile presents that as a potential use, not a universal outcome. Local conditions, tree health and careful evaluation still determine the result.
Aniyamma's story is a reminder that farmers are active experimenters. Years spent watching how a crop responds to soil, pests and weather can reveal possibilities that formal research may then test and improve. Read the original October 2026 profile in the digital edition.
