Chaudhary Charan Singh Haryana Agricultural University popularly known as HAU, is one of Asia's biggest agricultural universities, located at Hisar in the Indian state of Haryana. It is named after India's seventh Prime Minister, Chaudhary Charan Singh. It is a leader in agricultural research in India and contributed significantly to Green Revolution and White Revolution in India in the 1960s and 70s. It has a very large campus and has several research centres throughout the state. It won the Indian Council of Agricultural Research's Award for the Best Institute in 1997. HAU was initially a campus of Punjab Agricultural University, Ludhiana. After the formation of Haryana in 1966, it became an autonomous institution on February 2, 1970 through a Presidential Ordinance, later ratified as Haryana and Punjab Agricultural Universities Act, 1970, passed by the Lok Sabha on March 29, 1970.

    Studies on wheat-azotobacter interaction under pot house conditions
    (CCSHAU, 2008) Kusum; Vasudava, Manjula
    To study the varietal behaviour of wheat with regard to different strains of Azotobacter chroococcum, as experiment was conducted in which six varieties of wheat such as C-306, PBW-343, WH-283, WH-542, WH-147 and WH-711 were treated with two mutants of A. chroococcum Mac27 and HT54 at three levels of fertilizer such as O kg N ha-1, 90 kg N ha-1, 120 kg N ha-1 in terms of agronomical parameters under pot house conditions. Response of wheat varieties was studied towards A. chroococum in plant height, seed yield, total nitrogen content and total biomass. Variety C-306 showed best response towards both the strains of A. chroococcum. Mac27 showed better response as compared to HT54. Root exudates of these wheat varieties were analyzed for chemotactic behaviour and other components such as sugars, amino acids, phytohormones and organic acids. Glutamic acid and some other unidentified amino acids were detected in both inoculated and uninoculated wheat varieties. Succinic acid was present in wheat varieties WH-711 and WH-147. Maleic acid and some unidentified organic acids were detected in inoculated and uninoculated wheat varieties C-306, PBW-343, WH-283 and WH-542.
