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.

    Performance evaluation of root crop digger
    (CCSHAU, 2012) Narender; Vijaya Rani
    India is world s largest producer of vegetables after China and contributes about 14% of world vegetable production in year 2010-2011. In vegetables, potato, onion and carrot are the important root crops. In Haryana, potato (Solanum tuberosum L.) is grown in an area of 0.03 million hectares and production is 0.59 million tonnes and onion (Allium Cepa L.) in an area of 0.022 million hectares with a production of 0.45 million tonnes and carrot in an area of 0.02 million hectares giving a production of 0.315 million tonnes. The harvesting of root crop is presently done manually in India which is very tedious and time consuming. Moreover, sometime labour problem arises during harvesting operation. Though there are diggers available for different crops independently, they are not much accepted by the farmers. Therefore, it was proposed to evaluate the root crop digger which was designed to dig different crops namely potato, onion, carrot, turmeric, garlic etc. Five parameters i.e. exposed, cut, undug, bruised crop and digging efficiency of digger were studied at three different forward speed and blade angle to evaluate the performance of root crop digger for potato, carrot and onion crop. The optimized value for performance of the root crop digger was at speed 2.3 km h-1 and blade angle 230 for potato, speed 2.2 km h-1 and the blade angle 230 for carrot and speed 3.2 km h-1 and the blade angle 170 for onion crop. The field capacity of root crop digger was 0.21, 0.18 and 0.25 ha h-1 in potato, carrot and onion crop, respectively. The field efficiency of the root crop digger was 65 %, 65 % and 80 % for potato, carrot and onion, respectively. The saving in cost of mechanical digging was found to be 8384 Rs ha-1, 7359 Rs ha-1 and 5615 Rs ha-1 for potato, carrot and onion, respectively in comparison to conventional method. The break-even point for root crop digger was 35.14 hour per year. The payback period of root crop digger was 0.24 year.
