Question:

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

Answer:

One method of crop production is crop rotation method in which higher yield is obtained. In this method the crop is sown alternately. It cereal crops are planted in one year, pulses are planted in the second year. Due to this, the yield power of the field is maintained and there is no decline in the yield. Fertilizer is also not required much in crop rotation method, only manure works.
