Explain the impact of biotechnology on agricultural management with suitable examples.
उत्तर
- Genetically Modified Crops (GM crops) are being produced by introducing changes in DNA of natural crops. Normally, such varieties are not found in nature. Thus, new varieties are produced artificially. Different useful characters are introduced in such varieties.
- Ability to withstand environmental stress- Some naturally occurring varieties cannot withstand environmental stresses like frequently changing temperature, wet and dry famines, changing climate, etc. However, GM crops can grow in any of such adverse conditions.

- Due to use of seeds of GM crops, there is improvement in nutritive value and decrease in loss of crops.
