Explain any one method of crop production which ensures high yield.

Rotation of crops is a method of crop

production which ensures high yield. Crop

rotation is growing of different crop on the same piece

of land in a preplanned succession. Crop rotation

is done for one year, two year and three year

cycle. Crops chosen are such that they

withdraw nutrients from different layers of

the soil. Crop rotation involving a leguminous

crop ensures that the soil gets naturally

enriched with nitrogen. Crop rotation is useful

in (i) Weed control. (ii) Reduction in pest

infestation. (iii) Elimination of soil borne

diseases. (iv) Saving of nitrogen fertilizer (v)

Improving soil structure and fertility. (vi)

Raising of 2-4 crops in a year from the same

land giving higher returns to the farmer. (vii)

Yield of individual crops is also higher due to

improved soil structure, soil fertility, fewer

weeds insects and diseases.
