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.

    Chemical profiling and biological evaluation of Vetiver (Vetiveria zizanioides N.) essential oil
    (Chaudhary Charan Singh Haryana Agricultural University hisar, 2022-08) Pooja; Ravi Kumar
    The present study was undertaken for chemical profiling and evaluation of Vetiver (Vetiveria zizanioides N.) essential oil of promising Sugandha variety from different samples of roots (sample 1, sample 2, sample 3 and sample 4). Commercially available VEO was obtained from St. Botanica pharmacy store, Panchkula, Chandigarh which was ordered online. Sample 1, sample 2, sample 3 and sample 4 were harvested after 10 months, months, 18 months and 5 years of sowing. The EOs used in the study, appeared as pale yellow viscous volatile liquids, obtained in 0.55, 0.50, 1.16 and 0.26 % yield from sample 1, sample 2, sample 3 and sample 4, respectively. The yield was highest in the roots harvested after 12 months of sowing and lowest in roots which was harvested very late approximately after 5 years. A significant variation was observed in chemical composition of these VEOs. VO3 had more diversity and VO1 had lesser diversity. However, the chemical composition of VO5 was totally different from the other studied oils. The antimicrobial activity of VEOs was studied against various bacterial and fungal strains. VO3 showed higher antibacterial activity against K. aeruginosa, X. axonopodis pv. cyamopsidis, S. aureus and VO1 showed higher antifungal activity against F. oxysporum and M. grisea. Whereas, VO5 displayed least activity against tested strains.
