Question

210 frost-free days are required for the growth of cotton. What is the meaning of frost free days?

Answer 1

Cotton is a kharif crop that requires a high temperature, moderate rainfall or irrigation, and 210 days without freezing frost to mature. We like to use fertiliser or plants in sandy soil that is extremely rich. Cotton is vulnerable to both chilly temperatures and too much moisture in the soil. Cotton seed that is exposed to cold water in the hours following planting is more likely to be damaged.

Complete answer:
The average duration gap between the last frost day of the spring season and the first frost day of the fall season is defined as frost free days. The average number of days between the last spring frost and the first fall or winter lethal frost.
Cotton Cultivation Requires Specific Conditions. The following conditions must be met in order to successfully crop cotton:
1. Long Time Without Frost.

3. There is plenty of sunlight.
4. Cotton is grown in numerous parts of India, however it is most commonly grown in areas with black soil. In the north, it is also grown on alluvial soil.
