These three are the staples of about 80 percent of the world population,  and rice feeds almost half of humanity.

This theory was further confirmed by the study of Matsuoka et al. Weeds are controlled through the use of herbicidesand no cultivation tillage is done during the growing season.
Maize provided support for beansand the beans provided nitrogen derived from nitrogen-fixing rhizobia bacteria which live on the roots of beans and other legumes ; and squashes provided ground cover to stop weeds and inhibit evaporation by providing shade over the soil.
