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.

    Energy use pattern of pearl millet production and processing
    (CCSHAU, 2017) Kargwal, Raveena; Yadvika
    The aim of this study was to examine the energy input and output for pearl millet production and processing in HAU farm, selected villages of Hisar and Mahendergarh district of Haryana. Farmers with small, marginal and large land holdings were selected. The centre of excellence, pearl millet, HAU Hisar selected for studying processing of pearl millet of pearl millet. The data were collected through a questionnaire by face to face interviews. The amount of energy consumed in preparatory tillage, sowing, interculture, fertilizer, irrigation, pesticide, harvesting, threshing and transportation were calculated for pearl millet cultivation. The energy inputs in human labour, animal energy, machinery, fuel/diesel, fertilizer, pesticide and seed energy were taken into consideration to determine the amount of energy that was used in pearl millet cultivation. The average energy input of small marginal and large farmers of rainfed region was 4439.33MJ/ha, 4954.94MJ/ha and 5546.98MJ/ha, respectively while in irrigated region was 2824.87MJ/ha 3162.76MJ/ha and 4024.52MJ/ha, respectively. The total energy of HAU farm was estimated to be 4799.41MJ/ha. The average energy input-output ratio were found to be 7.08 in rainfed region, 6.12 in HAU farm and 10.97 in irrigated region.The two sources of energy consumed during processing of pearl millet were manual(8%) and electrical energy(92%).as electrical and human energy. The value of Σαi came out to be more than one in case of rainfed, irrigated region and HAU farm which means increasing return to scale or benefit to the farmers using Cobb-Douglas.

    Spent mushroom substrate utilization using different portable technologies
    (CCSHAU, 2016) Sandeep Kumar; Yadvika
    In present scenario, portable technologies are becoming popular because of their fabrication, installation, transportation and less space requirement. These are effective and efficient in terms of technology and cost. Mushroom industry is generating about 1-2 million tons per ton of mushroom harvested. Hence, the disposal of spent mushroom substrate is becoming a challenge for the mushroom growers. In the present study, three portable technologies i.e. Portable biogas plant, vermibed and biomass geyser were selected. Utilization of spent mushroom substrate was done using these portable technologies. Also one portable earthworm separator machine was developed during the course of this study. SMS was added as additive (2%) in 2 m3 portable biogas plant on alternative days for 4 months i.e. Jan-April. The average daily temperature varied between 18-40°C. Biogas production in control and SMS based biogas plants varied between 600 to 1214 litres and 726 to 1438 litres, respectively. The methane percentage was 55% in control and 60% in SMS based biogas plant. The benefit cost ratio of biogas plant came out to be around 1.5 and payback period was 3.62 years. Two portable vermibeds were fed with cattle dung and SMS in 2:1 and 4:1 ratio for compost preparation. The vermicompost was prepared in 70 days. N, P, K content of 2:1 based vermicompost were 0.16, 0.57 and 0.19% and 4:1 based vermicompost were 1.90, 0.57 and 1.54%. 4:1 based vermicompost was found to be better as compared to 2:1. The benefit cost ratio of vermibed was found to be around 4 and payback period was 3 months. The separation of vermicompost and earthworm was done using developed portable earthworm separator. It took 1 min to separate 2 kg of vermicompost. The separations efficiency was around 90%. The cost of this developed machine was Rs. 5000. Portable biomass geyser was operated on a mixture of cattle dung and SMS (5:1) for heating water. The cost of heating 100 litres of H2O came out to be Rs. 54 in case of electric geyser and Rs. 32 in case of biomass geyser. It can be concluded from the present study that SMS has proved to be a suitable additive along with cattle dung in portable technologies viz. Biogas plant, Vermibed and Biomass geyser. Hence, this waste can be disposed off in an eco friendly and more energy efficient manner using farmer friendly portable technologies.
