Question

Differentiate between mixed cultivation and crop rotation [2MARKS]

Answer 1

Differentiation: 2 Marks

In mixed cultivation, two or more different types of crops are sown in a particular field at the same time. For example: pea plants can be grown in the same field along with a cereal like wheat.

Crop rotation is a practice of growing two or more dissimilar crops in the same field one after the other. The nutrient requirements of a particular crop is kept in mind when crops are grown on a rotational basis. For example it is a known fact that paddy uses up lot of nitrogen from the soil. When planning for the subsequent crop to be sown, this fact is kept in mind . So leguminous plants like soya bean or pea are purposely sown so that this loss of nitrogen can be replaced naturally by them.
