DIG THIS!   about Corn:

Each ear of corn has about 800 kernels, all neatly arranged in about 16 rows.  Native American tribes planted a vegetable trio known as “The Three Sisters” because of how well the plants worked together.  The three plants included corn, pole beans and squash.  The corn plant was tall and sturdy enough for the beans to climb upon and grow, and the beans fixed nitrogen into the surrounding soil for the other plants, while the squash shaded the ground keeping in vital moisture.  With their prickly stems, the squash plants helped discourage hungry pests like raccoons from eating the corn.
