Did you know you can harvest tomatoes and potatoes from the same plant? It is possible to grow tomatoes and potatoes on a single plant, harvesting tomatoes above ground and potatoes below. This unique plant is known as a Pomato (or Pomtato), created through the grafting of a tomato plant onto a potato plant.
How the Pomato Plant Is Created
To achieve this, a farmer first plants tomato and potato seeds separately. Once they develop into seedlings, the farmer takes the tomato seedling (known as the scion) and attaches it to the potato seedling (called the rootstock).
As a result, the upper part of the plant grows as a tomato stem, producing tomatoes, while the lower part remains a potato root system, forming potatoes underground as usual.
The Science Behind Grafting
This technique, known as grafting, has been used for hundreds of years on various crops. It is commonly applied to improve plant size, enhance resistance to diseases, and increase overall productivity. You might wonder how a tomato can grow on a potato plant.
The main reason lies in the biological similarity between the two crops. Both belong to the Solanaceae family, which also includes crops like peppers and eggplants, meaning they are naturally compatible. Although grafting itself is not new, the Pomato plant remains relatively unknown to many people.
Benefits for Farmers and Food Security
Combining these two crops can help farmers maximize yields on limited land, addressing the challenge of land scarcity, which is a growing concern in Rwanda. Moreover, this innovation has the potential to boost both farmers’ incomes and the national economy, as tomatoes and potatoes are among the most widely consumed crops both locally and internationally.
The Pomato plant is a clear example of how agricultural research and innovation can help tackle global challenges such as food insecurity and population growth, which continue to contribute to hunger in many parts of the world.
