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.

    Integrated weed management in groundnut (Arachis hypogaea L.
    (CCSHAU, 2013) Yadav, Jagadish Prasad; Banga, R.S.
    A field experiment was conducted during kharif season of 2012 at Oilseeds Section, Department of Genetics and Plant Breeding, CCS Haryana Agricultural University, Hisar, to study the effect of integrated weed management practices in groundnut (Arachis hypogaea L.). The experiment comprising 15 treatments viz; pendimethalin @ 750 g/ha, pendimethalin @ 1000 g/ha, pendimethalin @ 750 g/ha + 1 HW 6 WAS, pendimethalin @ 1000 g/ha + 1 HW 6 WAS, alachlor @ 1000 g/ha, alachlor @ 1250 g/ha, alachlor @ 1000 g/ha + 1 HW 6 WAS, alachlor @ 1250 g/ha + 1 HW 6 WAS, oxyfluorfen @ 150 g/ha, oxyfluorfen @ 200 g/ha, oxyfluorfen @ 150 g/ha + 1 HW 6 WAS, oxyfluorfen @ 200 g/ha + 1 HW 6 WAS, two HW at 3 and 6 WAS, weedy check and weed free, was laid out in randomized block design with three replications. Alachlor @ 1250 g/ha + 1 HW 6 WAS, oxyfluorfen @ 200 g/ha + 1 HW 6 WAS and two HW at 3 and 6 WAS recorded significantly lower density and dry weight of weeds next only to weed free check. Weed free check recorded significantly highest number of pods per plant (25.9) closely followed by two HW at 3 and 6 WAS (20.6), which was on par with pendimethalin @ 1000 g/ha + 1 HW 6 WAS, alachlor @ 1000 g/ha + 1 HW 6 WAS, alachlor @ 1250 g/ha + 1 HW 6 WAS and oxyfluorfen @ 200 g/ha + 1 HW 6 WAS (18.2, 17.6, 18.6 and 17.8, respectively). Statistically highest shelling percentage was recorded in weed free treatment (69.7%) closely followed by oxyfluorfen @ 200 g/ha + 1 HW 6 WAS (67.7%) and two HW at 3 and 6 WAS (67.7%). All the yield parameters were significantly lower in weedy check. Significantly highest pod yield was recorded in weed free treatment (1913 kg/ha). Among chemical weed control treatments, oxyfluorfen @ 200 g/ha + 1 HW 6 WAS recorded higher pod yield (1555 kg/ha) closely followed by alachlor @ 1250 g/ha + 1 HW 6 WAS (1550 kg/ha). Statistically lowest pod yield was recorded in weedy check (605 kg/ha) over all other weed control treatments. Weeds growing throughout the crop season reduced the pod yield of groundnut to the extent of 68.4% compared to weed free check. Whereas, alachlor @ 1250 g/ha + 1 HW 6 WAS, oxyfluorfen @ 200 g/ha + 1 HW 6 WAS and two HW at 3 and 6 WAS provided effective control of weeds and thereby increased the pod yield of groundnut to the extent of 156-160% over weedy check. In present study, the weed free treatment recorded highest net return (Rs. 59477/ha) and higher B-C ratio (1:1.72). Among herbicidal treatments, higher net return and highest B-C ratio have attained in plots treated with alachlor @ 1250 g/ha + 1 HW at 6 WAS (Rs. 55949/ha and 1:1.92, respectively) closely followed by oxyfluorfen @ 200 g/ha + 1 HW 6 WAS (Rs. 55155/ha and 1:1.90, respectively).
