Introduction

Corn is the largest crop cultivated in the United States, with an annual production value exceeding 60 billion dollars.
The origins of U.S. corn production trace back over 5,000 years to ancient Mexico.

Early History

Modern corn, or maize, evolved from a wild grass known as teosinte.
Native Americans domesticated teosinte in Mexico, transforming it into a crop with a significant increase in kernel count.
Following its domestication, maize became a staple food for Native American populations across North and South America.

Early Cultivation

The initial cultivation of corn by Native Americans began more than 5,000 years ago.
Farmers practiced selective breeding by using seeds from healthier plants to enhance crop yields.
Surplus corn allowed for the establishment of food reserves, essential for winter sustenance.
The “Three Sisters” planting method was a key agricultural practice involving corn, squash, and beans.

The 'Three Sisters' Method

Planting corn, squash, and beans together produced numerous benefits.
Corn provides vertical support for beans, allowing the latter to climb the stalk.
Beans enhance soil fertility by fixing nitrogen, improving nutrient availability for crops.
Squash conserves soil moisture through its wide leaves, benefiting all three plants.
This symbiotic relationship reflects natural ecosystems, resulting in healthy, diverse crops while preserving soil quality.
