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.

    Bio-efficacy of different herbicides in maize (Zea mays L.)
    (CCSHAU, Hisar, 2021-09) Pardeep Kumar; Sangwan, Meenakshi
    The present study entitled “Bio-efficacy of different herbicides in maize (Zea mays L.)” was performed or conducted at Agronomy Farm, CCS Haryana Agricultural University, Hisar during Kharif 2020 with major objective to find out the effect of different weed control treatments on weeds, phenology, growth and yield of kharif maize. The experimental design used was Randomized Block Design with 18 treatments and three replications. The treatments were atrazine 750 g ha-1 as PRE, atrazine 750 g ha-1 as PRE fb atrazine 500 g ha-1 at 35 DAS, halosulfuron methyl 67.5 g ha-1 at 25 DAS, atrazine 500 g ha-1 + halosulfuron methyl 67.5 g ha-1 at 25 DAS, atrazine 750 g ha-1 as PRE fb halosulfuron methyl 67.5 g ha-1 at 35 DAS, atrazine 750 g ha-1 as PRE fb 2-4,D 500 g ha-1 at 35 DAS, atrazine 1000 g ha-1 as PRE fb one hoeing at 35 DAS, one hoeing at 20 DAS fb atrazine 500 g ha-1 at 35 DAS, atrazine 750 g ha-1 as PRE fb tembotrione 120 g ha-1 + S at 35 DAS, tembotrione 120 g ha-1 + S at 25 DAS, atrazine 750 g ha-1 as PRE fb tembotrione 120 g ha-1 + S at 35 DAS, topramezone 25 g ha-1 at 25 DAS, topramezone 25 g ha-1 + atrazine 500 g ha-1 at 35 DAS, atrazine 750 g ha-1 as PRE fb topramezone 25 g ha-1 at 35 DAS, paraquat as directed spray 800 g ha-1 at 25 DAS, atrazine 750 g ha-1 as PRE fb paraquat as direct spray 800 g ha-1 at 35 DAS, weedy check and weed free. Major weed flora infesting the field were Cyperus rotundus, Echinochloa colona, Dactyloctenium aegyptium and Convolvulus arvensis. Atrazine 1000 g ha-1 as PRE fb tembotrione 120 g ha-1 + S at 35 DAS and atrazine 750 g ha-1 as PRE fb tembotrione 120 g ha-1 + S at 35 DAS provided effective control of all types of weeds at different crop growth stages. Application of topramezone as POE is also effective against the weed flora but poor efficacy against C. rotundus. Among herbicide treatments at 50 & 80 DAS, atrazine 1000 g ha-1 as PRE fb tembotrione 120 g ha-1 + S at 35 DAS provided highest weed control efficiency (93.3 & 91 %) during kharif season. Among herbicidal treatments, maximum grain yield and yield attributes of maize were reported with PRE application of atrazine 1000 g ha-1 or 750 g ha-1 fb POE tembotrione 120 g ha-1 + S at 35 DAS (3942 and 3905 kg ha-1, respectively). No visual phyto-toxicity of any applied herbicide was observed in maize crop except with application of paraquat as POE at 25 and 35 DAS, phyto-toxicity symptoms i.e. yellowing, 40-50% and 20-30% were appeared on crop after 7 and 15 DAT, respectively. Maximum net returns (47106 & 46547 Rs. ha-1) and B:C ratio (2.6) was reported with atrazine 1000 g ha-1 as PRE fb tembotrione 120 g ha-1 + S at 35 DAS and atrazine 750 g ha-1 as PRE fb tembotrione 120 g ha-1 + S at 35 DAS.

    Performance of clusterbean cultivars under different resource conservation techniques
    (CCSHAU, 2010) Pardeep Kumar; Yadav, V.K.
    The field experiment entitled, “Performance of clusterbean cultivars under different resource conservation techniques” was conducted at Research Farm of CCS HAU Regional Research Station, Bawal (Rewari), during kharif season of 2009-10. The main plot treatments consisted of four resource conservation techniques (RCTs) viz. conventional tillage (CT), furrow irrigated raised bed system (FIRBS), zero tillage (ZT) with 5% wheat residue (WR) and ZT with 30% WR; and three cultivars HG 563, HG 365 and HG 2-20 were kept in sub-plots making twelve treatment combinations which were tested in split plot design with three replications. Different RCTs had significant impact on growth, yield attributes and yield of clusterbean and also on nutrient uptake by the crop. ZT 30% WR resulted into better growth and yield of all clusterbean cultivars. Maximum gross return was under ZT 30% WR, however, net return ( 24630 ha-1) and B: C ratio (3.17) was higher under ZT 5% WR. N, P and K uptake by various clusterbean cultivars was higher in HG 2-20. At crop harvest, available N, P and K content in the soil was more under ZT 30% WR. Among three clusterbean cultivars, HG 2-20 attained more growth and resulted into higher grain yield (1532 kg ha-1) closely followed by HG 563 (1419 kg ha-1) and HG 365 (1208 kg ha-1). Protein and gum yields were also higher in HG 2-20. HG 2-20 resulted into maximum net return ( 21997 ha-1) and B: C ratio (2.07). Thus, HG 2-20 coupled with ZT 5% WR was adjudged the most suited treatment combination for higher and economic yield. However, ZT 30% WR is expected to be remunerative and sustainable on long-term basis provided farmers can afford to retain at least 30% of previous crop residue on soil surface.
