Cereals have been the foundation of human civilization for millennia, providing sustenance and shaping societies across the globe.
Cereals, belonging to the grass family Poaceae, are cultivated for their edible grains or seeds. The most important cereals worldwide include wheat, rice, maize (corn), barley, oats, rye, and millet . These plants have been domesticated over thousands of years and have played a crucial role in the development of human societies .
Did You Know?
Cereals provide more food energy worldwide than any other type of crop and are therefore staple crops.
Global Impact
Over 50% of the world's caloric intake comes directly from cereal grains.
Historical Timeline of Cereal Cultivation
The domestication of cereals marked a pivotal moment in human history, enabling the transition from nomadic hunter-gatherer societies to settled agricultural communities .
c. 10,000 BCE
First Domestication - Evidence of early wheat and barley cultivation in the Fertile Crescent .
c. 7,000 BCE
Rice Domestication - Rice cultivation begins in the Yangtze River valley in China .
c. 6,000 BCE
Maize Development - Early forms of maize are cultivated in Mesoamerica .
c. 3,000 BCE
Spread to Europe - Cereal cultivation techniques spread throughout Europe .
18th Century
Agricultural Revolution - New farming techniques dramatically increase cereal yields .
20th Century

Biology and Cultivation
Cereals are annual plants, typically reaching 1-2 meters in height. Their structure includes roots, stems, leaves, and inflorescences that produce the grains we harvest .
Wheat
One of the first cereals to be domesticated, wheat is now cultivated worldwide and is a staple food for 35% of the world's population .
Rice
The primary staple for over half the world's population, rice cultivation requires specific water management techniques .
Maize
Originally domesticated in Mexico, maize is now the most produced cereal worldwide, with diverse uses from food to industrial applications .
