Q. Which of the following is/are correct for intercropping?

1. Inter-cropping is growing two or more crops simultaneously on the same field in a definite pattern.
2. The crops are selected such that their nutrient requirements are same.
3. Examples are soyabean + maize, or finger millet (bajra) + cowpea (lobia).

Select the correct answer from the codes given below:
Answer: Only 1 and 3
Notes: Inter-cropping is growing two or more crops simultaneously on the same field in a definite pattern. A few rows of one crop alternate with a few rows of a second crop, for example, soyabean + maize, or finger millet (bajra) + cowpea (lobia). The crops are selected such that their nutrient requirements are different. This ensures maximum utilisation of the nutrients supplied, and also prevents pests and diseases from spreading to all the plants belonging to one crop in a field.
