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.

    Comparative performance of evaporative cool chambers using alternative materials for storage of fruits and vegetables
    (CCSHAU, 2010) Yogender Singh; Yadav, Y.K.
    The investigations were carried out to study the comparative performance of evaporative cool chambers using alternative materials for storage of fruits and vegetables. Two evaporative cool chambers were constructed with the help of baked bricks. One of the evaporative cool chamber was filled with river bed sand whereas the other with rice husk ash. Temperature and relative humidty were recorded inside and outside the evaporative cool chambers for round the year use. It was found that for round the year average dry bulb temperature was 8.6ºC and 10.7ºC lower than ambient in evaporative cool chamber with river bed sand and in rice husk ash, respectively and the average relative humidty was by 53% and 57%, respectively higher than ambient. Low density polyethylene bags of thickenss 100 gauge (25 micron) with 1% perforation were also used in combination with these conditions for the storage studies. A comparative study was made for the storage of different fruits and vegetables inside the evaporative cool chambers and the ambient conditions and their physico-chemical parameters were observed at regular interval of time. The average cooling efficiency for round the year for evaporative cool chamber with rice husk was 14% higher than the evaporative cool chamber with river bed sand. Thus, the shelf life of the fruits and vegetables kept in these chambers increased substantially. The evaporative cool chambers extended the shelf life of fruits and vegetables by 2-3 times as compared to ambient. The evpaoriative cool chamber with rice husk ash was found more effective to retain the quality of fruits and vegetables. The evaporative cool chamber does not require mechanical or electrical energy input and can be constructed with locally available materials with unskilled labour, so the fruits and vegetables growers can use evaporative cool chamber with rice husk ash for short duration storage of horticultural produce.
