From UPSC perspective, the following things are important :
Prelims level: PUSA-44
Mains level: Stubble burning control measures
Central Idea
- Punjab CM recently announced the state’s decision to ban the cultivation of the PUSA-44 paddy variety starting from the next agricultural season.
- This move has raised questions about why such a popular paddy variety is facing a ban and what implications it holds for the state’s agriculture.
About PUSA-44
- Origin: Developed in 1993 by the Indian Council of Agricultural Research (ICAR), PUSA-44 gradually gained popularity among Punjab’s farmers.
- Rapid Adoption: Due to its high yield, Punjab’s farmers started cultivating it on a larger scale, covering 70 to 80 percent of the area under paddy cultivation.
Yield Comparison
- High Yield: Farmers favor PUSA-44 for its impressive yield, producing nearly 85 to 100 quintals per acre compared to other varieties’ 28 to 30 quintals per acre.
- Economic Advantage: The higher yield translates to increased income, with potential earnings of Rs 15,000 to 22,000 per acre above the Minimum Support Price (MSP).
Reasons for Ban
- Long Maturity Period: PUSA-44 requires around 160 days to mature, significantly longer than other varieties, necessitating 5-6 additional cycles of irrigation.
- Groundwater Depletion: Punjab faces severe groundwater depletion, and with an expanding area under paddy, the government aims to conserve water resources by banning PUSA-44.
- Stubble Burning: PUSA-44’s extended maturity period exacerbates the issue of stubble burning. The narrow timeframe between harvesting and wheat sowing makes stubble management challenging, leading to increased incidents of stubble burning.
- Air Pollution: Stubble burning contributes to severe air pollution in North India during the winter, impacting public health.
Impact of PUSA-44 on Stubble Burning
- Harvest Timing: PUSA-44 is harvested just before the wheat sowing season, leaving a limited window for stubble disposal.
- Stubble Quantity: PUSA-44 generates approximately 2 percent more stubble than shorter-duration varieties, compounding the stubble burning problem.
- High-Incidence Districts: Several districts in Punjab, including Barnala, Sangrur, Ludhiana, Moga, Patiala, Fatehgarh Sahib, Muktsar, Bathinda, Faridkot, and Mansa, witness higher stubble-burning incidents, coinciding with the PUSA-44 harvest.
Stubble Burning Statistics
- Burning Incidents: In 2022, several districts experienced a high incidence of stubble burning, primarily linked to the PUSA-44 harvest.
- Persistence: Stubble burning typically began in the third week of October, coinciding with the PUSA-44 harvest, and continued until November 25.
