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 herbicides for control of broad-leaf weeds in wheat
    (CCSHAU, Hisar, 2020-07) Ahmad Farhad Nekhat; Dhaka, Anil Kumar
    A field experiment entitled “Evaluation of herbicides for control of broad-leaf weeds in wheat” was conducted during Rabi season of 2018-19 at Research Farm area of CCS Haryana Agricultural University, Hisar, Haryana. The experiment was comprised of twelve post emergence herbicides (sole and their mixture) treatment i.e (Halauxifen-methyl ester + florasulam 40.85%WG + polyglycol 26-2N (0.25% v/v), metsulfuron-methyl 20 WP + 0.25% NIS surfactant, carfentrazone ethyl 40DF, 2, 4-D Na (80WP), 2, 4-D Ester (38 EC), metsulfurone-methyl 10% WP + carfentrazone 40DF + 0.2% surfactant, 2, 4-D Na + carfentrazone, 2, 4-D Ester + carfentrazone, halauxifen-methyl + florasulam + carfentrazone + surfactant, aclonifen 500 SC, diflufenican 100 SC and aclonifen 500 + diflufenican 100 SC) with different doses applied at 35 DAS, one weed free and weedy check on wheat variety WH 1105. Experiment was laid out in randomised block design with three replications. The major broad-leaf weeds infested wheat field were Chenopodium album, Convulvolus arvensis, Rumex dentatus, Anagallis arvensis and Melitotus indicus. Among all the herbicides and their mixtures tested, application of aclonifen 500 + diflufenican 100 SC @ 1750 + 1750 g/ha closely followed by application of Halauxifen-methyl + Florasulam + Carfentrazone + surfactant @ 24.99 + 50 + 750 g/ha at 35 DAS was found most effective against broad-leaf weeds except Convolvulus arevensis in wheat. Application of aclonifen 500 + diflufenican 100 SC @ 1750 + 1750 g/ha at 35 DAS was recorded with significantly higher plant height (110.7 cm), dry matter accumulation (346.3 g/mrl), effective tillers (107.7 /mrl), grains per spike (54.7), grain yield (6282 kg/ha), weed control efficiency (71.7%), net returns (65,733 Rs./ha) and B:C (1.82) at harvesting, which were 15.3, 18.3, 17.4, 21.6, 50.9, 71.1, 193.7 and 41.1 percent higher than weedy check plot, respectively. Based on study it is concluded that application of aclonifen 500 + diflufenican 100 SC @ (1750 + 1750 g/ha) at 35 days after sowing may be the most effective and economical to control the broad-leaf weeds and to obtain higher yield of wheat
