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.

    Engineering Interventions for Energy Efficient Management of Paddy Straw
    (CCSHAU, 2019) Sapna; Garg, M.K.
    The research was conducted in three phases: Biogas, Vermicompost and Pellets production from paddy straw. The biogas production was carried out in lab scale experiment using different ratios of cattle dung to paddy straw i.e. 100 % cattle dung, 1:1, 1:2, 1:3, 1:5 and 1:10. The highest biogas production from the lab scale experiment was recorded in ratio 1:5 and therefore, this ratio was used in pilot scale study. The daily biogas production and methane content was analyzed in the pilot scale experiment. The vermicompost production from the paddy straw was carried out using the paddy straw with cattle dung, biogas slurry and vegetable waste in different ratios. The vermicompost was matured after 60 days for first harvesting. The overall nutrient content was good in the combination of cattle dung + paddy straw +vegetable waste was comparable to control (100% cattle dung). For pellets production from paddy straw, pellet making machine was developed. Different parameters of the machine during pelleting and the characteristics of pellets were analyzed. The pellets were produced using 100:0, 80:20 and 50: 50 ratio of paddy straw and saw dust. Capacity of the machine was 12.6 kg of pellets/hour. The calorific value of pellets was recorded as 91.31cal/g. The pellets were produced when the machine was operating at a RPM of 38. The payback period of the machine was 2.5 years and B:C was 3.1.
