Note that this combination is a very synergistic combination of crops to grow together, and is millennia old.

"The Three Sisters planting method, commonly known as companion planting, entails growing corn, beans, and squash together in a mutually beneficial arrangement. It originated in North America around 3000 years ago.

...

Each plant brings unique advantages to the others; Corn serves as a trellis, providing a framework for the beans to grow and wrap around. Beans, acting as a natural fertilizer, add nitrogen to the soil, which benefits the growth of the corn and squash. Squash is typically planted between the corn and beans, and its ample leaves serve as a shield, blocking heat, retaining soil moisture and suppressing weed growth."
