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.

    Effect of fungicides and calcium nitrate on shelf life of Kinnow mandarin
    (CCSHAU,HiSAR, 2020-08) Sukrampal; Rana, G.S.
    The present investigation entitled “Effect of fungicides and calcium nitrate on shelf life of Kinnow mandarin” was carried out at post-graduate laboratory of the Department of Horticulture, CCS Haryana Agricultural University, Hisar during the year 2019-20. Spray of carbendazim, copper oxychloride, mancozeb, propiconazole, nimbecidine, calcium nitrate and their combinations was done ten days prior to harvesting on ten years old Kinnow plants in the experimental orchard of the Department of Horticulture, CCS HAU, Hisar. Application of pre-harvest treatments was laid out in Complete Randomized Design with three replications. Mature Kinnow fruits of uniform size, bruise and disease free were harvested with the help of secateurs. The harvested fruits were brought to the post-graduate laboratory and packed in corrugated fiber board boxes with newspaper lining. The boxes were kept at an ambient temperature and relative humidity in the post-graduate laboratory. The physico-chemical changes in the fruits were recorded at weekly intervals during storage. The fruits harvested from the plants treated with fungicides, nimbecidine, calcium nitrate, and their combinations exhibited significantly less decaying in comparison to the fruits of untreated plants. Carbendazim @ 0.05% + Calcium nitrate @ 1% proved most effective treatment in checking the post-harvest decaying of fruits followed by Propiconazole @ 0.05% + Calcium nitrate @ 1% . Both the treatments were significantly at par in respect to reduction of decay loss. The minimum loss in weight was also observed in Carbendazim @ 0.05% + Calcium nitrate @ 1% and Propiconazole @ 0.05% + Calcium nitrate @ 1% . The physical and quality parameters viz., juice content, rag content, organoleptic rating, TSS, acidity, TSS/acid ratio, reducing sugar, non-reducing sugar, total sugar of Kinnow fruits were found non-significantly affecting with various pre-harvest treatments. Among all the treatments, the maximum rind weight was observed in Carbendazim @ 0.05% + Calcium nitrate @ 1% (26.10%), whereas the maximum ascorbic acid content (24.15 mg/100 ml of juice) was reported in Mancozeb @ 0.2% + Calcium nitrate @ 1% during storage in Kinnow fruits. The most prominent pathogens associated with decay loss were identified as Colletotrichum gloeosporioides, Diplodia natalensis and Penicillium sp. during storage period.
