Answer: (c)
The growing of different kinds of crops on a piece of land in a preplanned succession is known as crop rotation. In the rotation of crops, leguminous crops like pulses, beans, peas, groundnut and Bengal gram are sown in-between the seasons of cereal crops like wheat, maize and pearl millet.
The leguminous plants are grown alternately with non-leguminous plants to restore the fertility of the soil. So it brings about an increase in the production of food grains. Besides, rotation of crops helps in weed control and pest control.
This is because weeds and pests are very choosy about the host crop plant, which they attack. When the crop is changed the cycle is broken. Hence, pesticide cost is reduced.
