PUSA-44

PUSA-44

1. Context

In its order on November 7, 2023, directing the Punjab, Haryana, Uttar Pradesh and Rajasthan governments to ensure that the burning of crop stubble is “stopped forthwith”, the Supreme Court mentioned a “particular kind of paddy… grown mostly in Punjab”. This variety and “the time period in which it is grown” were seen as major causes of stubble burning and the resultant pollution problems in the National Capital Region.

2. About Pusa-44

Pusa-44 is a high-yielding rice variety developed by the Indian Agricultural Research Institute (IARI) in 1993. It is a non-aromatic variety that is suitable for combined harvesting and is widely grown in the northern Indian state of Punjab. Pusa-44 is a long-duration variety that takes around 120-130 days to mature.

3. About Pusa-2090

Pusa-2090 is a new short-duration rice variety developed by IARI in 2023. It is a semi-dwarf, non-lodging, and non-shattering variety that takes around 110-115 days to mature. Pusa-2090 has been developed as a replacement for Pusa-44 to address the problem of paddy stubble burning in Punjab. Stubble burning is a practice followed by farmers in Punjab after harvesting their paddy crop to prepare the fields for the next crop. However, stubble burning is a major source of air pollution and has been linked to various health problems.

4. Differences between Pusa-44 and Pusa-2090

Characteristic Pusa-44 Pusa-2090
Duration Long (135-140 days) Short (110-115 days)
Yield potential 7-8 tons per hectare 7-8 tons per hectare
Grain quality Good Good
Resistance to pests and diseases Resistant to most pests and diseases Resistant to most pests and diseases
Lodging resistance Moderate High
Shattering resistance Moderate High

 

5. When did Punjab farmers begin cultivating PUSA-44?

Punjab farmers began cultivating Pusa-44 in the early 1990s. It quickly became the most popular rice variety in the state, accounting for over 50% of the total paddy area. However, in recent years, there has been a growing concern about the environmental impact of Pusa-44 cultivation. The variety requires a lot of water and fertilizer, and it is also known to produce a lot of stubble, which is often burned by farmers after harvest. This stubble burning contributes to air pollution in the region.

The Indian government is now encouraging farmers to switch to short-duration rice varieties like Pusa-2090. These varieties require less water and fertilizer, and they produce less stubble. The government is also providing subsidies to farmers who switch to short-duration rice varieties.
