Question

Which of the following rotation of crops will reduce dependence on the use of chemical fertilizers?

• A. Rice and Chilli
• B. Wheat and Potato
• C. Potato and Rice
• D. Gram and Rice

Answer 1

The correct option is D Gram and Rice

Crop rotation helps the farmers to maintain the fertility of the fields by growing alternate crops. A particular crop with one type of nutrient sown in one season restricts the cultivator to sow the other crop with another type of nutrient in the next season, which is most beneficial for the field e.g., gram is nitrogen rich crop and rice is sugar rich crop, so, their alternate cropping can give different nutrients to the field and thus, reduces the use of chemical fertilizers.
