A research team from Hajee Mohammad Danesh Science and Technology University (HSTU) in Dinajpur has demonstrated that potato cultivation can achieve conventional yields using only half the recommended amount of urea and phosphate fertilizers. The study, led by Associate Professor Dr. Md. Azizul Haque from the Department of Biochemistry and Molecular Biology, used a consortium of endophytic bacteria in field trials on the Granula potato variety. The method required no chemical pesticides, fungicides, or hormones, yet produced disease-free and high-quality potatoes.

The research found that endophytic bacteria enhanced antioxidant activity in potato leaves and roots, strengthening natural disease resistance and increasing microbial diversity in soil and plants. A participating farmer reported reduced costs and doubled profits per bigha compared to conventional methods. BRAC Microfinance, which funded the project, noted that the potatoes had stronger skins and longer natural storage life, improving marketability and food security.

According to experts, the innovation aligns with UN Sustainable Development Goals on sustainable agriculture, responsible production, climate action, and ecosystem conservation. Researchers hope broader field testing will confirm its potential for other crops and promote eco-friendly, cost-effective farming across Bangladesh.
