Step-by-step explanation:
When selecting a site for vegetable production, several factors are considered. These include the amount of rainfall, proximity to transportation, altitude, and the preparation of a nursery bed. The amount of rainfall is important because vegetables require adequate water for growth. Proximity to transportation is crucial for easy access to markets and distribution centers. Altitude can affect temperature and sunlight exposure, which can impact the growth of vegetables. Lastly, the preparation of a nursery bed is essential for providing optimal conditions for seed germination and early growth.
