Rare Frost Damage Hits Indian Rice Crops
28 Jan
Summary
- Low temperature stress caused rare paddy panicle choking in Kerala.
- Study conducted by Kerala Agricultural University scientists.
- 2026 saw more severe cold with 6 days below 12°C.
Paddy fields in the high ranges of Idukki and Wayanad districts have experienced a rare agricultural event where panicles failed to emerge due to low temperature stress (LTS). This phenomenon, known as 'choking,' was confirmed by a multidisciplinary team from Kerala Agricultural University.
The study, conducted during December 2025 and January 2026, identified LTS as the primary cause. This abiotic stress occurs when temperatures drop during critical growth stages, leading to poor fertilization and empty grains. Scientists noted that 2026 saw more severe cold, with 15 days below 13°C and six days below 12°C, compared to 2025.
Field observations ruled out diseases or nutritional deficiencies as the main culprits, as boot leaves remained green and the issue affected extensive areas with diverse soil conditions. Farmers in affected regions have expressed serious concerns about the future of agriculture.
