GAU develops high-yielding Aus variety

Researchers at Gazipur Agricultural University (GAU) have developed a short-duration, high-yielding fine Aus rice variety named “GAU Dhan 4”. 
Two professors from the Department of Agronomy – M Moynul Haque and Md Moshiul Islam – led the research which took a decade to develop the variety, reads a GAU press release.
The new GAU Dhan 4 variety matures within 90-100 days after sowing and under favorable conditions it can yield around 5-5.5 tonnes per hectare.
This feature is expected to be particularly beneficial for farmers in monga-prone northern regions, while its lower water requirement also makes it suitable for Aus cultivation across most parts of the country. 
The National Seed Board formally approved the variety as “GAU Dhan 4” at its 115th meeting on 5 February 2026.
GAU Dhan 4 grains contain about 24.58% amylose, aiding efficient carbohydrate digestion and energy supply, along with around 8.38% protein, which plays an important role in human growth and tissue repair. 
Prof Moshiul expressed hope the variety would increase farmers’ income and strengthen national food security. 
With the release of GAU Dhan 4, the total number of crop varieties developed by the university has reached 95, including four rice varieties.
