Explanation:

Wheat is a plant originating in the Middle East (Asia), cultivated for more than 500 years in Syria and of great importance to Babylonian and Egyptian people (Pharaohs era).

It is one of the main foods of humanity, occupies 20% of the cultivated area in the world.

Its production is around 500 million tons / year having as main world producers Russia (Ukraine), United States of America, China, India and France (together offer 60% of production).

Wheat needs fundamentally moderate temperatures, light and water.

The soil temperature must be around 15ºC, humidity around 120mm. (50-200mm.). Therefore tropical climates are not very suitable to its growth.
