Crop Production and Growth Factors

Questions and Answers

What is the primary factor that determines the optimal temperature range for specific crops?

The optimal temperature range for specific crops is primarily determined by the crop's genetic characteristics and growth stage.

How does polyculture farming differ from monoculture farming?

Polyculture farming involves growing multiple crops together in the same field, whereas monoculture farming involves growing a single crop per field.

What is the primary function of tillage in soil preparation?

The primary function of tillage is to break up the soil to improve its structure and aeration, allowing for better root growth and water infiltration.
