No Stones, No Grit! A Game-Changing Technology to Process Small Grain Introduced in Zimbabwe

Mar 14, 2024

By Shiela Chikulo

In Zimbabwe, the traditional, laborious, and time-consuming small grain processing may soon belong to the past, thanks to a game-changing technology: a multi-crop thresher. This scale-appropriate machine offers a smarter and less strenuous way to produce high-quality small-grain meals, including in drought-prone regions, without being contaminated with sand or stone particles.

“One of the main impediments to large-scale adoption of sorghum and millet in drought-prone areas is the laborious task of threshing. This has been solved by introducing multi-crop threshers, which form a central part in the business of mechanization service providers in rural Zimbabwe”, says Christian Thierfelder, principal scientist and project lead for the Mechanization and Extension Activity.

The introduction of the multi-crop thresher not only alleviates the physical strain of manual threshing but also enhances the overall quality of small-grain products. This innovation is a crucial step forward in promoting the production and consumption of small grains in Zimbabwe, contributing to food security and improved livelihoods for farmers.

This innovation was introduced by the Feed the Future Mechanization and Extension Activity, implemented by CIMMYT and funded by the United States Agency for International Development (USAID), to address the challenges of traditional small grain processing and offer new market opportunities to farmers.

Video: Western Canadian Agriculture: Hard Times Made the World's Best Farmers

Western Canadian agriculture produced the most advanced farmers in the world not through abundance but through adversity. The crow rate fell. The wheat price went nowhere. The brown envelopes stopped.

When the subsidies disappeared, the bad farmers left and the good ones stayed. And the ones who stayed could not just grow wheat anymore. They started growing lentils and canola and peas and flax and faba beans. They built crop rotation. They got serious about agronomy because there was no government backstop. That process produced the Western Canadian agriculture Dennis Bulani describes in this clip: the most advanced, most educated farming culture in the world.

His contrast with Iowa corn and soybean farmers is sharp. At a DeKalb farmer meeting in Okoboji, Iowa, he asked what crop rotation they ran. Beans on corn stubble, corn on bean stubble. How do you fertilize? The co-op agronomist handles it. Have you considered other crops? No need. We make so much money on corn and soybeans. Western Canadian agriculture was never allowed that comfort. And now those Iowa farmers are watching soybean markets lock up with China and corn prices slide, and they do not have the agronomy knowledge or the research base to pivot. Western Canadian farmers adapted on a dime because they had done it before.

Dennis also makes the case that Western Canadian agriculture keeps adapting in real time. Low commodity prices over the past year have pushed growers to look seriously at precision spot-spray technology. He knows a neighbor who bought a sprayer with the seeing-eye system and sprayed only 80 out of 320 acres. As a chemical retailer Dennis acknowledges that will affect his sales. He supports it anyway, because if it advances Canadian agriculture and makes farmers money, that is a good outcome.

The lesson Dennis draws from the tale of two farms: continuous improvement is the only durable strategy. When canola was $22 a bushel some growers went to Arizona instead of the Crop Production Show. When the price came down those same growers came back to the research and the discipline. Products do not go on Rack Petroleum's shelves unless they pass a replicated trial first. That is what Western Canadian agriculture built through hard times: farmers who do the work whether the times demand it or not.
