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.

    Biology and management of weeds in direct seeded rice
    (CCSHAU, 2019) Kuldeep Singh; Pannu, R.K.
    An experiment was carried out under field and lab./Screen house conditions at CCS HAU Hisar. In the field, efficiency of different weed control treatments in direct seeded rice during kharif season of 2012-13 and 2013-14 was studied. Among different pre emergence herbicides, pendimethalin proved most efficient in managing weeds at start of crop cycle. Post emergence application of azimsulfuron was most efficient for control of later emerged weeds. Among the given weed control treatments, pendimethalin @ 1.0 kg/ha (PRE) fb bispyribac-Na @ 25 g/ha + azimsulfuron @ 25 g/ha at 25 DAS was efficient in controlling weeds and producing highest yield in DSR. Weed biology of four grassy weeds, namely E. japonica, L. chinensis, E. glabrescens and D. aegyptium in lab. / screen house. Temperature range of 30-35OC, 7.0 pH, 0 MPa water potential, 0 mM NaCl, surface to 2.0 cm seeding and favored the germination and growth of all weeds species whereas, light has no effect. E. glabrescens was most tolerant to flooding as it withstands 80 days flooding, whereas D. aegyptium was most sensitive against flooding. In third part of experiment, sensitivity of above weeds to four herbicides viz. pyrazosulfuron, oxadiargyl, pendimethalin and cyhalofop-butyl+ penoxsulam was studied. Pendimethalin proved most efficient PRE herbicide that can be used in sequence with other POST herbicide and cyhalofop-butyl+ penoxsulam mixture can be used a POST herbicide in field dominated by E. glabrescens and L. chinensis.

    Response of Boron applications to sunflower (Helianthus annuus L.) under saline conditions
    (CCSHAU, 2016) Kuldeep Singh; Ram Parkash
    Six independent experiments were conducted on sunflower during 2011 at CCS Haryana Agricultural University, Hisar, India to study ''Response of Boron applications to sunflower (Helianthus annuus L.) under saline conditions. The experiment-1 entitled “Response of Boron (B) application to sunflower under Cl-dominated salinity” with four salinity levels (Control, 4, 8 and 12 dSm-1) and five Boron levels (Control, 1, 3, 6, 12 ppm), experiment-2 entitled “Response of B application to sunflower under SO4 2- dominated salinity” with four salinity levels (Control, 4, 8 and 12 dSm-1) and five Boron levels (Control, 1, 3, 6, 12 ppm), experiment-3 entitled “Performance of sunflower crop under Cl-dominated salinity” with four salinity level (Control, 4, 8 and 12 dSm-1) and four genotypes (HSFH-848 F2, 91A x R17, 91A x HRHA53 and Hybrid Jawalamukhi), experiment-4 entitled “Performance of sunflower crop under SO4 2-dominated salinity” with four salinity level (Control, 4, 8 and 12 dSm-1) and four genotypes (HSFH-848 F2, 91A x R17, 91A x HRHA53 and Hybrid Jawalamukhi), experiment-5 entitled "Retention and movement of Boron under Cl-dominated saline soils as affected by leaching levels" with five leaching level (200, 250, 300, 350 and 400 mm) by maintaining soil salinity 8 dSm-1 and experiment-6 entitled "Retention and movement of Boron under SO4 2- dominated saline soils as affected by leaching levels" with five leaching level (200, 250, 300, 350 and 400 mm) by maintaining soil salinity 8 dSm-1 were laid out in CRD with three replications in Pot (Experiment No.1to 4) and laboratory (Experiments 5 and 6). Salinity was created by pot experiments Na+1, Ca+2, Mg+2, Cl-1 and SO4 -2 salt in different quantity for different type of salinity. Boric acid was for preparing Boron levels. Germination of sunflower genotypes declined as salinity and boron levels were increased under both type of salinity. Seed yield, oil content and protein content also decreased with increase in salinity and boron levels. Boron concentration in stalk and seed was lower under saline conditions but its concentration was increased with boron levels. Ion concentrations were higher at higher levels of salinity and Na+, SO4 and Cl concentration in seed increased with B level and parallel the concentration of Ca and Mg was decreased in both type of salinity. Hybrid Jawalamukhi recorded the maximum germination percentage, seed yield, oil content and protein content in both types and all levels of salinity. Hybrid Jamalamukhi seed maintain higher Ca+2, Mg+2 and SO4 -2, and minimum content of Na+1 and Cl-1 to withstand against both types of salinity.
