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.

    Effect of poultry waste on biogas production and plant nutrient content of effluent under solid state fermentation of cattle dung
    (CCSHAU, 2005) Putatunda, Chayanika; Malik, R.K.
    Anaerobic digestion of organic wastes is gaining importance due to biogas recovery, production of organic manure and environmental protection. Apart from cattle waste biogas production has been reported from many other wastes like pig wastes, goat and sheep wastes etc. Many reports of biogas production from poultry wastes alone and in combination with other wastes like hog wastes, cattle dung are there. However, much work has not been done on the solid state fermentation of cattle dung supplemented with poultry waste. Cattle dung & poultry waste were collected from the animal farm and poultry farm, CCSHAU and analyzed. They were mixed in different ratios viz.100% CW (control), 90% CW +10% PW, 80% CW + 20% PW & 70% CW + 30% PW at approximately 17 % Total Solid concentration. Batch digestion was carried out for a period of 8 weeks in 5L aspirator bottles. The maximum biogas production was observed in digester with 30% PW (0.247 L/L/day) & minimum in the control (0.065 L/L/day).The influent & effluent were analyzed & highest enrichment of N, P &K was found in digester no. 4. (70% CD + 30% PW) The digesters were then converted to semi continuous mode during which they were daily fed with a particular amount of fresh substrate & same amount was taken out. The semi continuous system was operated for retention time period of 10 days, 20 days & 30 days. The maximum amount of biogas production was observed in all the digesters during RT of 30 days & the least during the RT of 10 days. Also, the biogas production was maximum in the digester no. 4 (70% CD + 30% PW), followed by digesters with 80% CD + 20% PW, 90 % CD + 30% PW and minimum in the control during all the retention time periods. Similar trend was observed in case of enrichment of N, P & K also. Maximum enrichment during RT of 30 days, followed by RT of 20 days & minimum during RT of 10 days was observed. Thus, addition of poultry waste to cattle dung proved to be beneficial both in terms of biogas production as well as enrichment of the effluent.
