describe how the practices of mixed cultivation and crop rotation help in increasing crop yeald.
Crop rotation helps in increasing crop yield by the following ways:
- It improves fertility of the soil
- It saves nitrogenous fertilizers as the leguminous plants grown in rotation increases the soil nitrogen level
- It helps in weed and pest control
- It is economically beneficial for the farmers
Advantages of mixed cropping:
- Two types of crops can be obtained at same time and cost.
- It reduces the risk of total failure as atleast one crop will grow if condition is not that adverse.
- Mixed cropping reduces the growth of weeds and pests.
- Cropping of leguminous plants with cereal crops increases the fertility which usually gets reduced by cereal cropping only.
