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.

    Study on nitrogen application under different methods of planting of sugarcane
    (CCSHAU, 2018) Kuldeep Singh; Rinwa, Ran Singh
    A field experiment entitled “Study on nitrogen application under different methods of planting of sugarcane” was conducted at Regional Research Station, Karnal of CCS Haryana Agricultural University during spring 2017. Soils of the experimental field were clay loam and near neutral with low organic carbon, low in available N and medium in available P and K. The experiment was conducted in split plot design with three replications and 24 treatments combinations. The treatments comprises of four methods of planting viz. Conventional planting at 75 cm (M1), Half ridge open furrow irrigation planting at 75 cm (M2), Wide bed and furrow paired row planting (35: 105 cm) (M3) and Wider planting (M4) at 120 cm and six different nitrogen levels viz. control (N1), 75 (N2), 100 (N3), 125 (N4), 150 (N5), 175 kg N ha-1 (N6) to work out effect of nitrogen application on yield and yield attributes as well as nitrogen use efficiency including their economics under different methods of planting. The results of finding reveals that planting the sugarcane with wide bed and furrow paired row planting significantly increased number of millable cane, cane yield and sugar yield over control. Highest cane yield (93.6 t/ha) followed by wider planting (86.7 t/ha) and half ridge open furrow irrigation planting (86.1 t/ha) over conventional methods (76.0 t/ha) with higher increment of 23.2 % in M3, 14.1 % in M4 and 13.3 % in M2 than M1 method, respectively was obtained. The significantly higher uptake of N, P and K was observed in wide bed and furrow paired row planting than conventional planting. The higher agronomic nitrogen use efficiency (NUE), per cent nitrogen recovery and physiological nitrogen use efficiency were also recorded in wide bed and furrow paired row planting method. Application of 175 kg N/ha being statistically at par with 150 kg N/ha (rec.) which significantly increased cane length, single cane weight, no. of tillers and number of millable cane over control. However, the maximum sugarcane yield (101.8 t/ha) was recorded at 150 kg N/ha application. The maximum agronomic NUE and per cent recovery were recorded at 150 kg N/ha. However, physiological efficiency showed a negative trend with increasing nitrogen application. The cane quality parameters viz. brix per cent, pol per cent, purity per cent and CCS per cent were not significantly affected by different planting methods and levels of nitrogen. The net return in wide bed and furrow paired row planting, wider planting, half ridge open furrow irrigation planting and conventional planting was Rs. 184039, Rs.164056, Rs.159692 ha-1 and Rs.128035 ha-1, respectively. Simultaneously, B:C was higher in wide bed and furrow paired row planting (2.53), wider planting (2.40) and half ridge open furrow irrigation planting (2.33) than 2.07 in conventional planting.

    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.

    Evaluation of some herbicides in clusterbean and their persistence
    (CCSHAU, 2010) Kuldeep Singh; Rinwa, R.S.
    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 clusterbean during kharif season of 2009-10 and their carryover effect on mustard crop was analyzed. Among different rates of imazethapyr, pendimethalin, trifluralin, pyrithiobac-sod and 2 HW weedings at 15 & 30 DAS, imazethapyr 80, 100 g/ha PRE and 100 g/ha 20 DAS resulted in significantly higher yield, but imazethapyr 100 g/ha PRE and POST had residue problems for mustard crop. So, imazethapyr 80 g/ha PRE may be used without much residue problems in the next cropping season for mustard. Also pendimethalin/trifluralin 1.0 kg/ha PRE/PPI followed by 1 HW 20 DAS and 2 HW at 15 & 30 DAS were found equally effective in controlling weeds and yield optimization of clusterbean. In lab/screen house study, persistence of trifluralin and imazethapyr affected by different temperature and moisture regime, using bioassay technique was quantified. Bioassay plants for trifluralin and imazethapyr were oat and mustard, respectively. Soils treated with above herbicides at different rates were incubated to 15, 25, 35 and 45OC temperature regimes in incubator and moisture incubations at 50%, 75% FC and FC at room temperature for one month. Persistence of herbicides affected by temperature and moisture regimes at different herbicide rates was measured by comparing the germination, shoot and root growth, fresh and dry weight to control treatment, at different intervals. Among given regimes of temperature and moisture, trifluralin degradation was maximum at 25OC and FC whereas, maximum degradation of imazethapyr was recorded between 35OC and 45OC and at 75 % FC.
