NABARD Agriculture notes – Cropping Systems
Mono-cropping or Single Cropping
- In this type of cropping system, a single crop is grown year after year on the piece of land. There is no rotation of crops. There are multiple reasons for following this type of cropping system like lack of rainfall, type of soil, environment, specialization, etc.
- Examples of Single or Mono-Cropping System are Groundnut cultivation, Flu cured Tobacco in Guntoor (AP).
- This is the practice of growing a single crop repeatedly over a long period without taking into consideration the crop intensity.
- Rice-Rice-Rice cropping pattern is an example of Monoculture cropping system.
- Growing one crop alone or in pure stand, either as a single crop or as a sequence of single crops within the year is called as Sole Cropping system. source: termwiki
Polycropping or Multiple Cropping
- The practice of growing more than one (usually 2 or 3) variety of crops on the same land within a year is called as Polycropping or Multiple Cropping.
- This system focuses on high input without affecting the overall fertility of the Soil.
- Multiple Cropping Includes Inter-cropping, sequence cropping and Mixed cropping
- The system of cultivation of more than 2 crops on the same farmland during every crop season over a long period of time is called as Polyculture.
- Relay Cropping system involves continues use of a land for growing 2 or more crops without a break.
- In this system, the second crop is usually sown when the first crop has reached its maturity and is ready for harvesting. The land is passed on from one crop to another just like the passing of a baton in a relay race from one runner to another.
- Overlapping system as the name suggests involves an overlapping of crops being sown on a land. The Next crop is sowed before the standing crop is harvested resulting in an overlap between the two crops.
Live Mulch System
- In a Living mulch system, a cover crop is interplanted with the main crop as a mulch to suppress the growth of weed or control the soil temperature to suit the growth of the main crop.
- Preventing Soil erosion because of water and wind is also a major benefit of Live Mulch cropping system.
- The practice of carrying out Crop Farming and Livestock farming simultaneously over the same land is called as Mixed Farming.
- Mixed farming is beneficial for both the crop and the livestock. The crops can be used as fodder for the livestock and the livestock excreta can act as an organic fertilizer for the crops and the soil.
- Ratooning is the agricultural practice of harvesting a monocot crop by cutting most of the above-ground portion but leaving the roots and growing shoot apices intact to allow the plants to recover and produce a fresh crop in the next season.
- This practice is widely used in the cultivation of crops such as rice, sugarcane, banana, and pineapple. source: Wikipedia
