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.

    Design and development of garlic (Allium sativum) stalk cutter machine
    (CCSHAU, 2019) Charan Singh; Garg, M.K.
    Garlic (Allium sativum) is a bulbous plant and perennial plant of amaryllis family (Amaryllidaceous). De-topping or cutting stalk is the primary unit operation for making the product marketable. Most of the de-topping is being done manually which not only time-consuming also adds cost. So in order to make the unit operation cost-effective and efficient a garlic stalk cutter machine was designed, developed and its performance was studied. In this study effect of operational parameters i.e. moisture content (14, 21, 28, 35, 42) % and feed rate (no of stalk-2, 3, 4, 5, 6) on dependent parameters such as capacity (kg/h), grading efficiency (%), bulb damaged (%), bulb dropped (%), plant spilled (%) and uncut stalk (%) were studied within the experimental region. Garlic variety GS17 was used during experiment. After complete evaluation and analysis of all attributes it was found that the best result was at a moisture content of 28% and feed rate of 4 stalks which resulted in a capacity of 177.62 kg/h with a grading efficiency of 91.4% and damaged bulb , bulb dropped , plant spilled , uncut stalk to be 2.63%, 2.30%, 1.32%, 3.68% respectively. After the optimization of parameters of the machine using RSM the result was found that on using feed rate 3.79 stalks at a time and moisture content of 29.012% resulted the capacity of machine and grading efficiency i.e. 174.2 kg/h., 90.87% respectively and the bulb damage, bulb dropped, plant spilled, uncut stalk i.e. 2.56%, 2.17%, 1.25%, 3.47% respectively.
