Question
Write the effect of biotechnology on agriculture and allied fields.
Solution
Effect of biotechnology on agriculture and allied fields are as follows:
- Genetically Modified crops (GM crops) are developed by altering the DNA of natural crops.
- These new varieties possess useful characters that can withstand adverse environmental stresses like frequently changing temperature, famines, changing climate, etc.
- GM crops with resistance to insect pests, pathogens and chemical weedicides can also be developed. This enables the farmers to reduce the use of harmful pesticides.
- There is an improvement in the nutritive value of crops and a decrease in crop losses due to the use of genetically modified or hybrid seeds.
- Biotechnology has helped enhance productivity and economic output from agriculture related fields like horticulture, floriculture, animal husbandry, apiculture, etc.
