Agricultural education was first started in Bihar in 1945 with the establishment of Bihar Agricultural College at Sabour in the district of Bhagalpur. Later on, it was realized that the agricultural situation and features of the plateau region of South Bihar is different from the rest of Bihar. Hence there was a need of a second college for this region. Ranchi Agricultural College was established in 1955, Ranchi Veterinary College in 1961 and College of Forestry in 1980. Considering the importance of agricultural education for the agricultural development of the state, the first Agricultural University in Bihar – Rajendra Agricultural University was started in1971 with its headquarters at Pusa. In view of the specific agriculture features of Chotanagpur and Santhal Parganas, the establishment of a second Agricultural University, for this region of the Bihar State, was conceived.
Birsa Agricultural University was established on 26th June, 1981 after its formal inauguration by the then Prime Minister of India, Late Smt. Indira Gandhi. Its primary objective is to develop area specific technologies and manpower in the field of agriculture, animal husbandry and forestry for the agricultural development of the plateau region of Jharkhand and economic upliftment of tribal and other backward class population of the region.
