Explanation:

 India is the largest producer and exporter  of  tea  in  the world. The ideal climatic conditions for the production and  growing of tea are as follows:

• Temperature: 21°C to 29°C is ideal for the production of tea. High temperature is required in summer. The lowest temperature for the growth of tea is 16°C.
• Rainfall: 150-250 cm of rainfall is required for tea cultivation.
• Soil: Tea shrubs require fertile mountain soil mixed with lime and iron. The soil should be rich in humus.
• Land: Tea cultivation needs well drained land. Stagnation  of  water is not good for tea plants. Heavy rainfall but no stagnancy of water, such mountain slopes are good for tea cultivation.
