1, high temperature and high humidity: The climate in India is usually hot and humid, which has an impact on the growth and quality of cotton. High temperature and high humidity may lead to excessive growth of cotton fiber and uneven fiber length, which may lead to the decline of fabric quality.

2. Drought and water shortage: Although some parts of India will have sufficient precipitation in monsoon season, drought and water shortage is still one of the factors affecting cotton quality. Drought leads to insufficient soil moisture, which may affect the normal growth and development of cotton, thus reducing fiber quality.

3. Strong winds and sandstorms: Some areas in India are often eroded by strong winds and sandstorms, which may also have a negative impact on the growth and quality of cotton. Strong wind may damage cotton plants, cause bolls to fall off or be damaged, and affect fiber quality.

4. Impact of pests and diseases: Climate conditions have an important impact on the occurrence and spread of pests and diseases. The climatic conditions in India are suitable for the survival and reproduction of pests and diseases, which may lead to the invasion of cotton by pests and diseases, thus reducing the yield and affecting the quality.

5. Unbalanced monsoon and rainfall: The distribution of monsoon and rainfall in India is unbalanced, and cotton planting in different regions may be affected by rainfall time and rainfall. If the rainfall time is not suitable or the rainfall is too much or too little, it may have an impact on the growth cycle and quality of cotton. Therefore, the unstable quality of cotton in India can be attributed to the uncertainty of climatic factors, including high temperature and high humidity, drought and water shortage, sandstorms, pests and diseases and uneven rainfall. These factors may have some negative effects on the growth and quality of cotton.
