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.

    Studies on the effect of irrigation and nitrogen levels on growth, yield and quality of onion (Allium cepa L.) under drip system
    (CCSHAU, 2019) Pooja Rani; Batra, V.K.
    The field experiment was conducted during Rabi season of 2016-17 and 2017-18 at Research Farm of the Department of Vegetable Science, CCS Haryana Agricultural University, Hisar to study the effect of drip irrigation and nitrogen fertigation on growth, yield and quality of onion. The experiment was laid out in a Split Plot Design with sixteen treatment combinations comprised of four levels of drip irrigation (60, 80, 100 and 120% CPE) as main plots and four levels of nitrogen fertigation (75, 100, 125 and 150 kg/ha) as sub plots and one control treatment replicated thrice. The seven to eight week old seedlings of onion cv. Hisar Onion 4 were transplanted at 15 x 10 cm spacing during the first week of January in both years The growth parameters, i.e., plant height, number of leaves per plant, leaf length and days to maturity were recorded maximum under drip irrigation at 120% CPE as compared to other levels of drip irrigation, whereas the all yield and quality parameters were recorded maximum with drip irrigation at 100% CPE as compared to other levels of irrigation except that neck thickness, fresh and dry weight of leaves, split bulbs, bolting percentage and unmarketable bulb yield. However, maximum water use efficiency (59.20 and 60.60 kg/ha/mm) was recorded with the drip irrigation 60% CPE as compared to other high levels of drip irrigation. Among the different levels of nitrogen fertigation, all growth parameters were observed maximum with 150 kg/ha nitrogen fertigation as compared to other levels of nitrogen fertigation. Yield and quality parameters were recorded higher under 125 kg/ha nitrogen fertigation, whereas nitrogen use efficiency (263.53 and 259.80 kg/ha, resp.) was found highest with the fertigation of 75 kg nitrogen as compared to rest of fertigation treatments in both yea` Interaction of irrigation and nitrogen fertigation also significantly affected the almost all growth, yield and quality paramete` The highest benefit cost ratio (3.35 and 3.62) was obtained from drip irrigation at 100% CPE and 125 kg/ha nitrogen, while the lowest benefit cost ratio (1.60 and 1.61) was found at 60% CPE with 75 kg/ha nitrogen fertigation during both years, respectively.
