Context
To counter the twin challenges of climate change and malnutrition, PM Narendra Modi launched 35 new indigenously-developed crop varieties developed by ICAR. The one that is making it into the news is the country’s first-ever non-GM (genetically modified) herbicide-tolerant rice varieties.

About New Varieties of Rice:
Mechanism of its herbicide-tolerance:
Efficient use of water and reduction in labour:
Direct Seeding Techniques (DSR) requires 30 per cent less water for cultivation, saves up to Rs 3,000 per acre in transplantation in labour charges and about 10 to 15 days in cultivation as it doesn’t need to prepare a nursery. |
Why this is better than GM herbicide-resistant rice?
Pre-emergent herbicides: These are chemicals applied before germination. It can also be applied immediately after sowing using ordinary seed drills. E.g.: pendimethalin. Post-emergent herbicides: these chemicals are sprayed 20-25 days after the sowing of the seeds. E.g.: Bispyribac-sodium, Fenoxaprop-p-ethyl, etc. |

Conclusion:
We need to opt for both traditional farming and new agricultural practices based on technological advancements. It is time that we fine-tune the balance between the ‘back to basic’ and ‘march to future’ approaches. ICAR has played a pioneering role during Green Revolution and has been continuously been contributingtoIndian agriculture through its research and technology development. The development of crops which are climate-resilient, fortified and uses less water, is importantnot only for the progress of agriculture but alsoto address the twin challenge of climate change and malnutrition.
