Good quality seed: the basis for good production and better yield in the cultivation of native potatoes and Andean tubers
Systems for the provision of seeds of native potatoes and Andean tubers, economic and sustainable for family agriculture, allow to improve the crop yield .
Context of the story
Family farming (FF) is key to eradicating hunger and proposing changes to more sustainable farming systems. In Latin America, 80% of farms belong to FF. Within FF of high Andean regions, potatoes (S. tuberosum), ulluco (U. tuberosus), oca (O. tuberosa) and mashua (T. tuberosum) are essential for food security, as they are an accessible source of calories, vitamins and antioxidants. Among the difficulties that RTA cultivation presents in countries such as Bolivia and Colombia, is the low yield, particularly of traditional varieties. One of the causes of low yield is poor seed quality. In Bolivia and Colombia, on average only 2% of farmers use good quality seed to establish their crops
Production of good quality seeds of native potatoes and andean tubers and adoption of IPDM strategies for improving crop yields
The implemented initiative
Through strategies of Participatory Rural Innovation, this platform seeks to improve the system of potato and Andean tubers production of small producers in Bolivia and Colombia, with the use of seeds of good genetic and phytosanitary quality. The seed is expected to be available continously for small farmers, without relying on third parties to supply it. The adoption of IPDM strategies in crops aims to achieve a decrease in the use of agrochemicals, which will positively impact the environmental sustainability of production systems.
The use of good quality seed, the adoption of IPDM strategies and the socio-organizational strengthening, improve the yield of potato crops and Andean tubers in family farming
The technological solution
With the strengthening of the community fabric of the families participating in the project, it is hoped to improve the system of potato and Andean tubers production of small producers, encouraging the use of seeds of good genetic and phytosanitary quality. In Colombia, the production of native potato seed will be implemented in a "pilot laboratory" managed by farmers trained in the use of biotechnological tools for in vitro tissue culture. In Bolivia, the cleaning of the seed through in vitro tissue culture will be carried out by the UMSS, which, in association with the municipality of Sacaba, will be responsible for the continuous supply of seed to farmers in the area. Likewise, it is expected that with the adoption by farmers of agro-ecological designs and the incorporation of different strategies in IPDM programs in their crops, the use of agrochemicals decrease, which will positively impact the environmental and economic sustainability of crops.
