Bihar Agricultural University (BAU), Sabour is a state agricultural university established on 5 August 2010 in Bhagalpur district, Bihar. Although the university is relatively recent, its institutional roots extend to the historic agricultural college at Sabour, where the foundation stone of the Bengal Provincial Agricultural College was laid on 17 August 1908. The heritage college later became Bihar Agricultural College and developed into one of eastern India’s important centres for agricultural education. BAU was created as an autonomous university with a network of constituent colleges, research stations and Krishi Vigyan Kendras. Its mandate combines graduate and postgraduate education, basic and applied research, technology development, farmer training and extension. Official university information describes academic units in agriculture and horticulture, regional research stations distributed across Bihar’s agro-ecological zones, and an extensive KVK network used for field-level technology transfer. Sabour has a notable place in agricultural-extension history. The Department of Extension Education was established in 1954, and postgraduate study in Extension Education began in 1955, making Bihar Agricultural College an early pioneer of formal postgraduate extension education in India. After Rajendra Agricultural University was established at Pusa in 1970, Bihar Agricultural College became affiliated with that university before the later creation of BAU. Research at BAU addresses crop productivity, soil and water management, horticulture, plant protection, agricultural engineering, climate resilience and rural livelihoods. The university combines laboratory research with on-farm validation and farmer outreach. Its distinctive strength is therefore the integration of more than a century of agricultural teaching at Sabour with a modern statewide system of colleges, research stations and extension units serving farmers across multiple agro-climatic zones of Bihar. BAU’s Indo-Gangetic location makes its research relevant to rice, maize, horticulture, soils, water management and climate-resilient farming. Its education and extension functions are closely linked to the practical needs of Bihar’s farmers and agricultural workforce.
