A crop that farmers grow mainly to sell for a profit is called a cash crop. Examples of cash crops include cotton, tobacco, and soybeans. These crops are cultivated primarily for their economic value rather than for subsistence or personal consumption. Farmers often choose cash crops based on market demand and potential profitability.
Humans in Palaeolithic period were hunter gatherers not farmers/crop growers

Vietnam's farmers grow cocoa, rice is the most important food crop, followed by corn, cassava, and sweet potato, in that order.
Farmers get the majority of their seeds from crop breeders who specialize in producing seeds to grow the plants that farmers grow to sell their crops with. The seeds that farmers keep from the crop they sow often won't be suitable enough to grow again, especially with crop varieties like corn, wheat and canola.
One problem GMO crops pose for farmers who do not grow them is cross pollination of GMOs in non-GMO crops, especially those that are grown organically.
The crop that farmers depend on depends on the main crop that each farmer grows. Farmers depend on the crops that bring them the most money to live on, such as wheat, corn, lettuce, tomatoes, or peanuts. Many farmers grow more than one crop so that if one fails they still have another one to fall back on.
Farmers add acids and alkalis to their soil to adjust the pH level. Different crops thrive in different pH ranges, and by modifying the soil pH, farmers can create optimal conditions for their crops to grow. This helps improve nutrient availability, enhance plant uptake, and ultimately increase crop yields.
Most crops are grown for profits for farmers, not for personal use. Only in the third world countries like most of Africa and India will you find farmers that grow and harvest rice and wheat for their own use.
