4. All of these ​

Answer 1

Explanation:

The requirements of the cotton plant

Constant temperatures between 18 and 30°. Ample sunshine and fairly dry conditions. A minimum of 500 mm of water between germination and boll formation. Deep, well-drained soils with a good nutrient content.

Answer 2

Option D) Cultivation of cotton requires all of these.

• Fertilizers are extremely essential for the proper growth of all crops. For cotton crops, fertilizers supply nitrogen, phosphorous, and potassium.
• Cotton plants are quite vulnerable to pests like bollworms. This can cause huge losses to the farmers. Hence pesticides are used to kill these pests.
• Cotton plants produce flowers that have seeds inside them. To grow cotton plants, those seeds are planted.
