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.

    Energetics and techno economic assessment of different paddy straw densification processes
    (CCSHAU, 2018) Hemant Kumar; Vijaya Rani
    In India, a large portion of the residue is burnt on-farm primarily to clear the field for sowing of the succeeding crop. The burning of straw creates health, soil and environment hazards. From the total crop residue, cereal crops (rice, wheat, maize, and millets) contribute 70% while rice crop alone contribute 34%. Management of this huge amount of paddy straw becomes difficult for farmers. Many solutions are being tried to manage the paddy straw one of them is straw removal from field by making bales which can be easily handled and transported for animal feed, power generation, brick kiln etc. In the present study different densification process viz., using field baler after operation of stubble shaver with and without operation of hay rake. In third case loose straw was directly collected from field and baled by field baler in stationary mode. Further, full length straw and chopped by chaff cutter was used to make bale in hydraulic pressed type fixed stationary. In the study it was found that, if the harvesting of paddy is done by combine, then operating field baler after operation of stubble shaver and hay rake was most appropriate providing a maximum field capacity of 0.54 ha h-1, baling capacity 4.43 t h-1, volume compaction ratio of 5.26 with minimum time required of 0.44 h, man-h 3.57, energy of 102.65 MJ t-1 and cost of baling Rs 624 t-1. The scented variety of rice is mostly harvested manually for which the full length densification by a hydraulic press type fixed baler is appropriate with baling capacity 1.13 t h-1, maximum volume compaction ratio 6.87 and lowest cost of operation Rs 595 t-1. The transportation, storage become easy and safe with bales than loose straw. Maximum benefit was obtained with stationary baler for full length straw.
