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 tractor drawn straw reaper for paddy straw
    (CCSHAU, Hisar, 2019-08) Ujala; Saroha, Anil
    Rice (Oryza sativa) is one of the leading and widely cultivated cereal crops in the world. India has the world‟s largest area under rice with 43 million ha and is the second largest producer next only to China with production of 104 million tonnes during 2015-16. The productivity of rice was around 24q ha-1 during the agricultural year 2015-16 (Anonymous, 2017). The tractor drawn paddy straw reaper was evaluated at farmers field in Ludas village of Hisar district for optimization of machine parameters viz., cylinder speed (550, 750 and 950 rpm), forward speed (1.0, 1.5 and 2.0 km h-1) and crop parameter viz., straw moisture content (20.4 to 49.5 %) in relation to field capacity, field efficiency, fuel consumption, straw size, straw recovery and straw split percentage for paddy varieties Pusa-1121 and Pusa-44. For the paddy variety Pusa-1121 the field capacity, field efficiency, fuel consumption and power consumption at optimum conditions were 0.23 ha h-1, 66.37%, 5.33 l ha-1 and 21.82 kW, respectively. The straw size, straw recovery and straw split at optimum condition were 3.30 cm, 65.11 % and 89.11 %, respectively. Similarly for paddy variety Pusa-44, the field capacity, field efficiency, fuel consumption and power consumption at optimum conditions were 0.20 ha h-1, 59.45%, 5.67 l ha-1 and 23.70 kW, respectively. The straw size, straw recovery and straw split at optimum condition were 3.46 cm, 62.89 % and 86.23 %, respectively. Moisture content of 20.4-20.8 per cent, forward speed of 1.5 km h-1 and cylinder speed of 950 rpm was found optimum for paddy varieties Pusa-1121 and Pusa-44. The cost of operation was Rs 5190 ha-1and Rs 6112 ha-1 in Pusa-1121 and Pusa-44 variety, respectively. The machine was found economically feasible for the farmer‟s.
