Answer Details

The major physical factor that restricts the cultivation of perennial crops in the Sudan savannah of Nigeria is the seasonal pattern of rainfall. The Sudan savannah experiences a short rainy season and a long dry season, which makes it difficult to cultivate perennial crops that require a constant supply of water throughout the year. The seasonal nature of rainfall leads to water stress, which affects the growth and yield of perennial crops. Therefore, the cultivation of perennial crops in the Sudan savannah is restricted to areas with reliable water sources, such as rivers or irrigation facilities.
