Abiotic factors influence crop production in the following ways :

1. Sunlight helps in photosynthesis.

2. Water and minerals from the soil along with gases are the raw materials for synthesis of food and energy.

3. Appropriate temperature is required for proper growth of plant and various processes such as transpiration.
