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.

    Characterization of biochar prepared from coconut shell at different temperatures
    (CCS HAU, Hisar, 2022-07-22) Bhawna; Dahiya, Rita
    Pyrolysis process can be the solution to problems that arises due to the improper management of biowaste. This process might be used to produce valuable carbonaceous products like biochar. The present study is focused on the preparation of biochar from coconut shell at different temperatures by pyrolysis. The obtained biochar was characterized by using analytical techniques like FTIR, XRD, BET, FE-SEM and UV-Vis spectroscopy. The properties of biochar like ash content, EC, pH, carbon content and CEC were also determined using standard methods. The FTIR spectra of the prepared biochar confirmed the presence of aromatic carbon functional group in the biochar structure. From the XRD plots, amorphous structure of the biochar is confirmed. The results indicated that as the pyrolysis temperature increased, the amorphous organic phase in the biochar structure decreased. The FE-SEM images showed the porous structure of biochar prepared at a high temperature of 700 °C. The BET analysis showed that as the pyrolysis temperature increased, surface area as well as porosity of the biochar increased.

    Evaluation of advanced wheat lines for stripe rust resistance and grain quality
    (CCSHAU, Hisar, 2019-08) Bhawna; Bhawna; Yadav, Neelam R.; Yadav, Neelam R.
    Biofortification of staple foods like wheat without any yield penalty is of utmost importance. Advanced lines introgressed with Gpc-B1 allele were used in the study. The Gpc-B1 allele co-segregated with Yr36 yellow rust resistance gene in all the advanced lines. All WH711-derived advanced wheat lines confirmed for the Yr36/Gpc-B1 allele. Seven advanced lines (WL-8-1, WL-8-2, WL-8-3, WL-8-5, WL-8-6, WL-8-7, WL-8-8) were confirmed for Yr18 while six advanced lines (WL-8-1, WL-8-2, WL-8- 6, WL-8-7, WL-8-8, WL-8-9) were positive for Yr17 gene. All five PBW343-derived advanced lines confirmed for the Yr36/Gpc-B1 allele presence. Three advanced lines (PL-8-2, PL-8-3, PL-8-4) displayed the presence of the Yr18 gene. Two advanced lines (Pl-8-3, PL-8-5) confirmed presence of the Yr17 gene. All the advanced wheat lines derived from WH711 as well as from PBW343 displayed very high levels of resistance against yellow rust and better agronomic characteristics than the parents. Positive correlation was observed in yield and yield related traits. The hectoliter weights of PBW343-derived lines indicated their superiority in terms of good flour recovery than PBW343 and comparable to the checks. WH711- and PBW343- derived advanced wheat lines show better gluten quality and high quantity in sedimentation test. Gpc-B1 allele introgression provided high GPC in WH711 derived advanced wheat lines. Iron and zinc contents of both WH711-derived and PBW343-derived advanced wheat lines were at par when compared to either parent and checks, indicating successful bio fortification of both micronutrients. Two of the WH711-derived lines are being further tested in IPPSN/station trials.

    Studies on effect of post-harvest treatments and storage conditions to enhance shelf life of ber (Ziziphus mauritiana L.)
    (CCSHAU,HiSAR, 2020) Bhawna; Goyal, R.K
    The present experiment entitled “Studies on effect of post-harvest treatments and storage conditions to enhance shelf life of ber (Ziziphus mauritiana L.)” was conducted in the Department of Horticulture, CCS Haryana Agricultural University, Hisar during 2019-20. Fruits were treated with post-harvest treatments viz. lemongrass oil 0.1%, til oil 2%, Aloe vera 100%, salicylic acid 1mM, calcium chloride 2%, citric acid 0.5%, sodium nitroprusside 1mM and control. Fruits were stored at room temperature as well as cold storage conditions. The minimum loss in weight, decay loss and maximum colour, specific gravity, sugars and total chlorophyll content were recorded in fruits treated with Aloe vera 100%. The maximum fruit firmness was observed in fruits treated with Aloe vera 100% and salicylic acid 1mM whereas, maximum ascorbic acid was observed in calcium chloride 2%, salicylic acid 1mM and Aloe vera 100% treated fruits at room temperature storage. The minimum loss in weight, decay loss and maximum fruit firmness, specific gravity, organoleptic quality and total chlorophyll content were maintained by fruits treated with Aloe vera 100% under cold storage conditions. The maximum ascorbic acid content, total soluble solids and sugars were observed in fruits treated with calcium chloride 2% under cold storage conditions. The maximum free radical scavenging activity was observed in fruits treated with salicylic acid 1mM under both room and cold storage conditions. Loss in weight and decay loss increased with prolongation of storage period whereas, ascorbic acid content, acidity, fruit firmness and specific gravity decreased with the advancement of storage period under both storage conditions.
