Improving potato production and farmer knowledge in Bolivia

In the rolling hills of Villa Charcas, the lives of potato farmers are changing as the Association of Potato Producers of Los Cintis, is on a mission to improve potato yields and productivity per hectare. Under guidance of agricultural extension specialists Alex Villca and Félix Roque Castro, and in close collaboration with PUM expert Harrie van Wijk, about 50 farmers of the association are discovering how new techniques can turn modest harvests into thriving crops.

During a 10 day stay in Bolivia, Harrie made several farm visits and soil analysis, and identified key areas for improvement, including seed potato quality, fertilisation strategies, and pest management. By addressing these challenges, farmers can increase yields and reduce losses, fostering greater food security and economic stability within the region.

Practical solutions for enhanced yields
“One of the main issues identified is the quality of seed potatoes, some of which are affected by Rhizoctonia, a disease that reduces yields”, explains Harrie. “I encouraged the farmers to treat seed potatoes with recommended products and experiment with small test plots to observe improvements.” Fertilisation practices are also being optimised. By testing slightly higher and lower fertiliser applications across different rows, farmers can see firsthand what works best for their soils.

Crop protection and safety practices
Training has also emphasised personal safety when using crop protection products. Demonstrations showed farmers simple, effective ways to protect themselves, such as using improvised barriers and applying sprays with the wind behind them. These practices help safeguard the health of farmers and farm workers, contributing to a safer, more sustainable agricultural community. Innovative ideas such as growing winter cover crops to improve soil health and establishing small-scale production of speciality products like native potatoes or onion oil have the potential to open new markets.

Young farmers, new ideas
One of the recommendations Harrie made was to start study groups and youth farmer clubs as  vital tools for knowledge exchange. By visiting fields together and learning from each other, farmers build stronger networks, share best practices, and accelerate the adoption of improved techniques. Hopefully these groups will inspire other young people in the community to see agriculture as a path to opportunity rather than just tradition.

Strengthening the community
The most profound impact is on the community itself. Farmers are sharing what they learn, supporting one another, and building networks that extend beyond fields and harvests. Families see the benefits through better yields, more reliable income, and opportunities for young people to stay in agriculture. As Alex Villca puts it, “This isn’t just about potatoes. It’s about our future, our families, and our community.”
