"Different ways of growing crops can be used to give maximum benefit from crop production management." Explain any three techniques.

(N/A) $(i)$ Mixed cropping: Growing two or more crops simultaneously on the same piece of land is called mixed cropping.
For example: Wheat + gram, or wheat + mustard, or groundnut + sunflower.
$(ii)$ Intercropping: Growing two or more crops simultaneously on the same field in a definite pattern is called intercropping.
For example: Soybean + maize, or finger millet (bajra) + cowpea (lobia).
$(iii)$ Crop rotation: The growing of different crops on a piece of land in a preplanned succession is known as crop rotation.
For example: Growing two or more crops on a piece of land during a year to maintain soil fertility.
