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.

    Management of mungbean yellow mosaic virus in mothbean [Vigna aconitifolia (Jacq) marechal]
    (CCSHAU, 2007) Sunil Kumar; Gupta, P.P.
    Mothbean is a major commercial crop of hot arid regions of our country. It is affected by several fungal, bacterial and viral diseases. Among these mungbean yellow mosaic virus (MYMV) disease is the most important. Out of 62 genotypes screened against MYMV disease under field conditions and seventeen among them screened under green house conditions only 12 genotypes including one promising resistant check viz., RMM-47-2, RMM-44, GMO-4, RMO-257, RMB-54, CZM-90, HM-61, CZM-12, RMO-435, GMO-13, GMO-9915, CAZRI Moth-1 were found moderately resistant. Second week of June for sowing and spacing 45 cm were optimum in reducing the incidence of MYMV disease and whitefly population. The yield was also maximum (10.33 q/ha) at this conditions. There was positive correlation between disease incidence and whitefly population and yield was negatively correlated with disease incidence and whitefly population. The correlation of disease incidence with weather parameters were found non-significant. Application of phosphorus and potassium (40 kg/ha each) alone reduces the disease incidence from 47.8% (in control, no application of NPK) to 17.8% and 18.3% respectively. Highest reduction in MYMV disease incidence (70.61%), minimum whitefly population and maximum grain yield with respect to 20 kg/ha nitrogen application alone was recorded when N20P40K40 kg/ha were used. The botanical Azadirachtin (Fortune Aza, 5%) was most effective than other botanicals in reducing the MYMV disease incidence (69.43%) and increasing the grain yield (84.56%). This treatment was statistically at par with the application of Endosulfan (0.07% a.i.). Neem oil (5%) was found better next to the Azadiractin in reducing the disease incidence.
