Use of genetically modified crop variety- Genetically modified crop varieties are those in which their genetic material has been slightly changed with the help of recombinant DNA technology. Thus the crop varieties with desirable traits are raised for better yield.
Use of hybrid varieties- Hybrids are generally more vigorous than parent plants. Hybrids varieties are obtained by crossing genetically different parents. Hybrids plants have generally traits of both the parent plants
Pest management- Various chemical, mechanical and biological practises are used to keep the pest under control. Bio control of pest is preferred over other methods.
