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.

    Evaluation of some herbicide mixtures against resistant Phalaris minor in wheat
    (CCSHAU, 2014) Anisha; Samunder Singh
    An experiment was carried out under two location, one was Research farm of Department of Agronomy and other was screen house CCS HAU Hisar. In the study, efficacy of herbicide mixtures and their effect on growth and yield of wheat crop was observed. At 60 DAS minimum population of P. minor was recorded in pinoxaden + ally express 50 % DF (metsulfuron+carfentrazone) @ 50 + 25 g/ha 35 DAS which was statistically similar to pendimethalin + pyroxasulfone @ 1000 + 106 g/ha PRE and pendimethalin + pyroxasulfone @ 1000 + 127.5 g/ha PRE. Tank mix application of pendimethalin + pyroxasulfone @ 1000 + 106 g/ha PRE and pendimethalin + pyroxasulfone @ 1000 + 127.5 g/ha PRE were superior compared to their alone application. Pendimethalin @ 1.5 kg/ha PRE was least effective on A. ludoviciana but its tank mixture with other herbicides significantly lowered the population of A. ludoviciana. There was no crop phytotoxicity observed under any applied herbicides. Among herbicidal treatments maximum number of tillers (181.0 and 178.6 no/m 2 ) were observed under pendimethalin + pyroxasulfone @ 1000 + 127.5 g/ha PRE and pendimethalin + pyroxasulfone @ 1000 + 106 g/ha PRE treatment, respectively at 90 DAS. Flufenacet @ 400 g/ha PRE used alone or as tank mixture provided lower control compared to pyroxasulfone @ 127.5 g/ha PRE used alone or as tank mix partner with other herbicides 2 & 3 WAT at screen house. Weed dry weight was found to be nil at 5WAT as there was complete mortality of resistant as well as suceptible populations under screen house. Among mixed herbicide treatments, the lowest biological yield (115.3 q/ha) was recorded in metribuzin + flufenacet @ 140 + 300 g/ha 17 DAS treatment. Highest grain yield, maximum net return and maximum B:C ratio was obtained under pinoxaden + ally express 50 % DF (metsulfuron+carfentrazone) @ 50 + 25 g/ha 35 DAS fb pendimethalin + pyroxasulfone @ 1000 + 127.5 g/ha PRE treatment.
