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.

    Weed management in transplanted rice
    (CCSHAU, 2009) Naresh Kumar; Nandal, D.P.
    The present investigation was carried out at the Students’ Farm of College of Agriculture, CCS Haryana Agricultural University, Kaul (Kaithal) during Kharif 2008. The main objective was to find out the best herbicide, which control the weeds significantly and help in crop growth. The experiment consisted of fifteen treatments viz., two doses of post-emergence herbicides, bispyribac sodium (25 and 30 g/ha) and azimsulfuron (30 and 40 g/ha) with two timings of their application (20 and 25 DAT) and one dose of fenoxaprop-p-ethyl 56.25 g/ha (25 DAT). Four pre-emergence herbicides pretilachlor 750 g/ha, butachlor 1500 g/ha, oxadiargyl 100 g/ha, pyrazosulfuron 20 g/ha along with weedy and weed free checks and were laid out in randomized block design with three replications. The experimental field was dominated by grassy, broad leaf weeds and sedges viz. Echinochloa colona, Echinochloa crusgalli, Ammania baccifera, Ludwigia parviflora, Lindernia spp., Marsilea quadrifolia, Cyperus iria and Cyperus difformis. The weed dry weight and density were significantly lowest in pretilachlor treatment. The growth parameter plant height, tillers/m2 and crop dry matter accumulation/m2 were statistically higher in pretilachlor treatment. Grain and straw yield was also significantly higher in pretilachlor treatment. Among the new post-emergence herbicides bispyribac sodium 25 & 30 g/ha (20 DAT) was found excellent herbicide. Bispyribac sodium 25 & 30 g/ha (20 DAT) were statistically at par to weed free treatment to control the grassy weeds and sedges. Azimsulfuron 30 & 40 g/ha (20 DAT) were statistically at par to weed free treatment in controlling broad leaf weeds. Butachlor 1500 g/ha and pyrazosulfuron 20 g/ha (3 DAT) were significantly at par to weed free treatment to control all types of weeds. Gain and straw yield of pretilachlor, butachlor, bispyribac sodium (25 and 30 g/ha applied at 20 DAT) and pyrazosulfuron were statistically at par to weed free treatment.
