Many countries in Africa also undergo a depletion of fertile soil. In regions of dry climate like Sudan and the countries that make up the Sahara Desert, droughts and soil degradation is common. Cash crops such as teas, maize, and beans require a variety of nutrients in order to grow healthy.
Maize is a tall annual grass with a single stem, ranging in height from 1.2 m (4 ft) to 4 m (13 ft). [31] The long narrow leaves arise from the nodes or joints, alternately on opposite sides on the stalk. [31] Maize is monoecious, with separate male and female flowers on the same plant. [31]

The protein from maize is further enhanced by protein contributions from beans and pumpkin seeds, while pumpkin flesh provides large amounts of vitamin A; with the Three Sisters, farmers harvest about the same amount of energy as from maize monoculture, but get more protein yield from the inter-planted bean and pumpkin. Mt.
Squashes provided an excellent source of protein to the ancient Mesoamericans, as well as to people today. Another major food source in Mesoamerica are beans. Maize, beans, and squash form a triad of products, commonly referred to as the "Three Sisters". Growing these three crops together helps to retain nutrients in the soil.
The output of wild maize did not justify the time and work needed to grow the crop. However, maize could be both dried and stored which was very important to early Mesoamericans as it could be used on a year-round basis. Drying meant that it could be transported as well. The common bean (Phaseolus vulgaris) was often grown with maize. These two ...
The production of corn (Zea mays mays, also known as "maize") plays a major role in the economy of the United States. The US is the largest corn producer in the world, with 96,000,000 acres (39,000,000 ha) of land reserved for corn production. Corn growth is dominated by west/north central Iowa and east central Illinois. Approximately 13% of ...
