Duration of Rotation

The growing of different crops on a piece of land in a preplanned succession is known as crop rotation. Depending upon the duration, crop rotation is done for different crop combinations. Depending upon the duration, crop rotation is classified as:

  • One-year rotation: Rice-Wheat, Maize-Mustard
  • Two-year rotation: Maize-Mustard-Sugarcane-Fenugreek, Maize-Potato-Sugarcane-Pea
  • Three-year rotation: Cotton-Sugarcane-Pea-Maize-Wheat, Rice-Wheat-Mung-Mustard-Sugarcane-Berseem
  • Selection of crops for rotation: Most commonly, legumes are included in the crop rotation programme. They are used to increase soil fertility. Those crops which require high fertility level (e.g., wheat) may be grown after growing legumes (e.g., pea). Thus, high input crops such as sugarcane, potato, maize, wheat and rice may be grown before low input required crops. Thus while making selection of crops for crop rotation, the following points should be considered:

  • Availability of moisture through rain or irrigation.
  • Status of nutrients in the soil
  • Availability of inputs such as fertilizers, pesticides, human power and machine power
  • Duration of crop-short or long
  • Marketing and processing facilities.
