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.

    Co-composting of kitchen and garden waste using microbial inoculants
    (CCSHAU,HiSAR, 2021-10) Choudhary, Rahul; Kayasth, Monika
    Composting is a preferred and environmental sound method in which organic waste is reduced to organic fertilizer and soil conditioners through biological processes. Microorganisms are able to convert organic waste into micro and macro nutrients to be utilized by plants and reduce C:N ratio to support soil productivity and to minimize ecological imbalance. The parameters including C:N ratio, composting temperature, pH of the finished product and moisture content are used to assess the quality and stability of the compost. In the present investigation, the isolated microbes were assessed for their composting abilities using kitchen and garden wastes. About 42 morphologically distinct bacteria and fungi were isolated from different sources using serial dilution method on Nutrient Agar and Potato Dextrose Agar media, respectively. These isolates were further screened for cellulase, pectinase and amylase activities. The composting was carried out for a period of 90 days using various kitchen waste, garden wastes and cattle dung. The composting resulted in reduction of total organic carbon from 41.50% to 29.6% after 90 days. Similarly, the C:N ratio of compost was reduced from 41.50 to 26.42. On the other hand, the Nitrogen, Phosphorus and Potassium contents of compost were found to be increased significantly during the progression of composting process. The treatment T8 was found to be the best for compost formation with a significant advantage compared to the other treatments with the maximum humic substance content and germination percentage of 115.51 mg/g and 91.14%, respectively.
