### Theory:

Crop rotation is planting different crops, chosen in a series and grown on a piece of land in a pre-planned succession.
The rotation of crops depends upon the crop duration. The availability of moisture and irrigation facilities decide the crop that needs to be cultivated after one harvest. If crop rotation is done correctly, two to three crops can be grown in a year with good harvests.

Crop rotation

Monocropping and mixed cropping are two methods through which crops are produced. Monocropping is the repeated cultivation of the same crop in the same field year after year.

Monocropping

Mixed cropping involves growing two or more crops simultaneously on the same land without any defined pattern.
Example:
Wheat $$+$$ gram, Wheat $$+$$ mustard, Groundnut $$+$$ sunflower, Maize $$+$$ green gram, Maize $$+$$ black gram.
Maize $$+$$ Green gram
