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.

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.
Climate with large number of days with sunshine and fertile soils, permits growing of more than one crop annually on the same plot. Farmers use their small land holdings to produce enough for their local consumption, while remaining produce is used for exchange against other goods.
The Yecoro wheat (right) cultivar is sensitive to salinity, plants resulting from a hybrid cross with cultivar W4910 (left) show greater tolerance to high salinity. Plant breeding is the science of changing the traits of plants in order to produce desired characteristics. [1]
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.

Agriculture was the main economic activity in ancient Mesopotamia.Operating under harsh constraints, notably the arid climate, the Mesopotamian farmers developed effective strategies that enabled them to support the development of the first known empires, under the supervision of the institutions which dominated the economy: the royal and provincial palaces, the temples, and the domains of the ...
Maize reached the Southwest via an unknown route from Mexico. Its diffusion was relatively rapid. One theory is that the maize cultivation was carried northward from central Mexico by migrating farmers, most likely speakers of a Uto-Aztecan language. Another theory, more accepted among scholars, is that maize was diffused northward from group ...
