Chaudhary Charan Singh Haryana Agricultural University, Hisar

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. A. L. Fletcher, the first Vice-Chancellor of the university, was instrumental in its initial growth.

    Mathematical modeling of performance characteristics of combine harvester
    (CCSHAU, 2005) Gurmeet Singh; S. Aggarwal
    In this study, mathematical models were developed for pre-harvest loss, header loss, grain breakage, threshing efficiency, threshing loss and fuel consumption for wheat and paddy crop harvested by combine harvester. The data was taken from commercial test reports of twenty-five combines tested at Northern Region Farm Machinery Training &Testing Institute, Hisar. Regression analysis was carried out for developing mathematical models for the afore said variables depending on the independent variables such as crop yield, moisture content of the grains at the time of harvesting, forward speed of the combine, threshing drum speed, and field efficiency. The developed models were tested for their validity with the actual performance of the combines and the developed model for header loss of wheat was compared with existing model given by Audsley and Boyce. The developed model was found more efficient. With the help of developed models various dependent variables such as pre-harvest loss, header loss, grain breakage, threshing efficiency, threshing loss and fuel consumption can be predicted while operating with a combine in a particular field. The total crop residue of wheat and paddy in Haryana was also estimated. It was 44.27 and 24.6 lacks tones respectively for wheat and paddy.
