The Indian Agricultural Research Institute (IARI), commonly known as the Pusa Institute,[3] is India's national institute for agricultural research, education and extension. The name Pusa Institute is derived from the fact that the institute was originally located in Pusa, Bihar as the Imperial Institute of Agricultural Research in 1911. It was then renamed as the Imperial Agricultural Research Institute in 1919 and following a major earthquake in Pusa in 1934, it was relocated to Delhi in 1936. The current institute in Delhi is financed and administered by the Indian Council of Agricultural Research (ICAR). The IARI was responsible for the research leading to the "Green Revolution in India" of the 1970s.[4][5] IARI ranked First among Agriculture and Allied Universities in the National Institutional Ranking Framework NIRF (India Rankings 2023). [6][7]

The institute was established in 1905 at Pusa, Bihar, with financial assistance of Henry Phipps, Jr., an American philanthropist. Phipps was a family friend of Lady Curzon, who was a daughter of an American millionaire, and the wife of Lord Curzon, the Viceroy of India. Phipps stayed as a guest of the Curzons during his visit to India and left behind a donation of £30,000, which was used to establish the institute. He laid the foundation stone of the Agricultural Research Institute and college on 1 April 1905.[8] The institute was originally called the Agricultural Research Institute (ARI). Its name was changed to the Imperial Institute of Agricultural Research in 1911, and to the Imperial Agricultural Research Institute in 1919.[3] The choice of establishing it in Pusa in northern Bihar was the proximity to the indigo plantations which were in need of revival following the German synthesis of aniline in 1899. One of the first scientists to be deputed to the institute was the English chemist John Walter Leather who had worked from 1892 with the agricultural department in India. He moved to the institute in 1906.[9][10]

However, the institute was damaged during the devastating Bihar earthquake of 15 January 1934. The Secretary of State approved the transfer in July, 1934.[11] The Standing Finance Committee of the Union Assembly finally announced on 25 August 1934 in Shimla, the decision to shift the institute to New Delhi at the approximate cost of 3.8 million (US$48,000).[12] to a place that is now called Pusa in New Delhi. The director B. Viswanath, a soil scientist was to be the first Indian to head the institute. The new campus at New Delhi was inaugurated on 29 July 1936,[3] while the new building of the Imperial Institute of Agricultural Research was inaugurated by the then Viceroy of India, Lord Linlithgow on 7 November 1936.[13]

Post-independence, the institute was renamed the Indian Agricultural Research Institute,[3] and in 1950 the Shimla sub-station of institute developed Rust-resistant varieties of wheat, including Pusa 718, 737, 745, and 760.[14] In 1958, it was recognized as a "deemed university" under the UGC act of 1956[15] of Parliament and since then it has awarded MSc and PhD degrees.[3]

What remained of the institute at the original location was downgraded to an agricultural research station until 1970, when the Government of Bihar established the Rajendra Agricultural University at the location.[8]


The campus is spread over 500 hectares (5.0 km2), 8 km west of New Delhi Railway Station. This was initially outside Delhi, but over the decades the city has grown much beyond the campus.[16] Indian Agricultural Statistics Research Institute is affiliated with and is located in the campus of the Indian Agricultural Research Institute.[17]
