Study Notes
Herbicide-Tolerant Basmati Rice
- ICAR has commercialised herbicide-tolerant (Ht) basmati rice varieties for effective weed control.
- These varieties allow for the direct application of the herbicide Imazethapyr thanks to a mutated ALS gene.
- ICAR specifically focuses on non-genetically modified (non-GM) Ht basmati rice to promote agricultural sustainability.
Direct Seeded Rice (DSR)
- DSR is a modern rice cultivation technique where seeds are directly sown into the field, bypassing traditional transplanting methods.
- This method is noted for being efficient and environmentally sustainable, benefiting farmers and the economy.
- DSR eliminates the need for transplanting seedlings, streamlining the planting process.
Weed Control Techniques
- Research indicates that hand weeding at intervals of 20 and 40 days after sowing is more effective than Imazethapyr application for weed control.
- Hand weeding not only improves weed management but also enhances seed yield compared to repeated herbicide applications.
Environmental Considerations
- ICAR advocates for eco-friendly hand weeding as a preferred method for controlling weeds and ensuring higher seed yields.
- The emergence of herbicide-resistant weeds poses a significant threat to rice production and overall food security.
