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.

    Optimization of biogas slurry use for digestion of an admixture of kitchen waste and cattle dung
    (CCSHAU, 2011) Sunil Kumar; Yadav, Y. K.
    Anaerobic digestion of kitchen waste and cattle dung was carried out in laboratory scale batch mode reactors in two phases. In the first phase, anaerobic digestion with different mixture of kitchen waste (KW) and cattle dung (CD) with 20% inoculum was carried out whereas in the second phase, anaerobic digestion of mixture of KW and CD with different concentration of inoculum was carried out. Five feedstock of which were made by mixing kitchen waste and cattle dung at different mixing ratios of 0:1 (P1R1), 1:3 (P1R2), 1:1 (P1R3), 3:1 (P1R4) and 1:0 (P1R5) were tested. The result showed that reactor P1R3 (50% KW + 50% CD) with kitchen waste and cattle dung ratio of 1:1 gave the maximum (21.3 l/kg of solid substrate) biogas with volumetric biogas production of 0.37 l/kg/d and methane yield of 0.092 m3/kg VS added with solid conversion efficiency of 142 ml/g TS and 162 ml/g VS added. After completion of first phase, the best mixture obtained was 50% KW + 50% CD (P1R3). In the second phase, this mixture was digested with different concentrations of inoculums viz. 10%, 15%, 20% and 25%. The maximum biogas yield was of (27.6 l/kg of solid substrate) observed in reactor P2R4 (50% KW + 50% CD with 25% inoculum) with volumetric biogas production of (0.48 l/kg/d) and methane yield of 0.085 m3/kg VS added with solid conversion efficiency of 127 ml/g TS and 145 ml/g VS added. Therefore, mixing ratio of 1:1 of kitchen waste and cattle dung was optimal for biogas yield, methane yield and solid conversion efficiency with 25% inoculum.
