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 herbicide resistance in Rumex sp.
    (CCSHAU, 2019) Sunil; Garg, Rajbir
    The present investigation entitled, “Evaluation of herbicide resistance in Rumex sp.” was carried out during rabi season of 2017-18 in the screen house of Department of Agronomy, Chaudhary Charan Singh Haryana Agricultural University, Hisar (Haryana). This pot experiment was conducted in a completely randomized design, replicated thrice. In order to evaluate the issue of herbicide resistance in this weed, herbicides recommended for the control of broad leaf weeds in wheat crop namely metsulfuron, Total, carfentrazone, Lanfida, Atlantis, isoproturon, 2,4-D amine and ester salt, Accord plus, diflufenican, aclonifen + diflufenican, halauxifen + fluroxypyr, aclonifen, halauxifen, pendimethalin, metribuzin were applied at three doses (0.5X, X and 2.0X ) in the experiment as pre-emergence or post-emergence intervention as per the nature of particular herbicide. One unsprayed control was also kept for each population and herbicides for comparison. The results in general indicated that Rumex biotype have attained resistance against metsulfuron, Total, Atlantis and, isoproturon. The moderate efficacy and tolerance even at double the recommended doses was observed in carfentrazone, Lanfida, 2,4-D amine and ester salt, Accord plus, diflufenican, aclonifen + diflufenican aclonifen and halauxifen. Higher values of plant height, chlorophyll fluorescence, fresh weight and dry weight and lower value of EC was observed in the herbicidal treatments showing comparatively less efficacy against the weed. The post-emergence application of halauxifen + fluroxypyr provided good control of Rumex sp. even at half of recommended dose. The good efficacy of this herbicide combination provides opportunity to integrate this herbicide in weed managment options in wheat crop at field level. The pre-emergence application of pendimethalin and metribuzin gave complete control even at half of the recommended dose. The pre-emergence application of pendimethalin, pre and post-emergence application of metribuzin have already been recommended and promoted for the management of Phalaris minor in wheat crop. One single intervention may provide management of complex weed flora infesting the wheat crop. The information collected from this study will facilitate proactive management of herbicide resistant through sequential application of pre-emergence and post-emergence herbicides and also using the compatible herbicide mixtures in rotations to reduce the selection pressure and tackle the proliferation of resistant bio-types.

    Effect of zinc and sulphur on growth, yield and quality of clusterbean (Cyamopsis tetragonoloba (L.) Taub.)
    (CCSHAU, 2017) Sunil; Bhattoo, M.S.
    The present study entitled Effect of zinc and sulphur on growth, yield and quality of clusterbean (Cyamopsis tetragonoloba (L.) Taub.), was conducted at cotton research station, Sirsa during Kharif 2015. The soil of the experimental field was loamy sand, slightly alkaline in reaction, low in organic carbon and nitrogen, medium in phosphorus, low in zinc and sulphur. The experiment was conducted in RBD with three replications. The experiment consist of 16 treatments in which N and P were applied as per recommended dose (N= 20kg/ha, P2O5= 40kg/ha) along with different doses of Zn (10, 20 and 30kg/ha) and S (20, 30 and 40kg/ha) and their combinations. Growth parameters viz. plant population, plant height and dry matter accumulation were recorded maximum in T16 (N@20 kg + P2O5@40 kg+ ZnSO4@30 kg + S @40 kg/ha). Yield attributes viz. no. of pods/plant, no. of grains/pod, Yield viz. grain, straw and biological yield were also recorded highest in T16, while maximum harvest index was observed in T8 (N@20 kg + P2O5 @40 kg+ ZnSO4 @10 kg + S@20 kg/ha) and highest 1000 grains weight (test weight) was observed in T13 (N @20 kg + P2O5@40 kg+ ZnSO4@20 kg + S @40 kg/ha) as compared to other nutrient treatments. Quality parameters viz. gum content and protein content were recorded highest in T16. Maximum nutrient content (N, P, S and Zn) and nutrient uptake in grain and straw also recorded highest in T16. In clusterbean, cost of cultivation and gross returns were recorded highest in T16, while T13 recorded highest net returns and B: C than other nutrient treatments. All the parameters were recorded lowest in control treatments. It may be concluded that T16 resulted in better growth parameters, yield attributes, quality parameters, soil nutrient and economics except harvest index higher in T8, B: C and net returns higher in T13. Increased in growth and yield parameter was observed, further study can be explored to optimize the nutrient requirement for yield maximization, profitability and sustainability
