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 packaging materials and post-harvest essential oil treatments on the storage behavior of potato cultivars
    (CCSHAU, 2018) Archana Rani; Bhatia, A.K.
    The present investigation entitled “Effect of packaging materials and post-harvest essential oil treatments on the storage behaviour of potato cultivars” was carried out in Post-Harvest Laboratory of the Department of Horticulture Sciences, CCS Haryana Agricultural University, Hisar during the year 2015-16 and 2016-17. The four potato varieties, i.e., Kufri Bahar, Kufri Sadabahar, Kufri Surya and Kufri Pushkar were packed in gunny bags, nylon netted bag, cotton bag, polyethylene bag (LDPE) and plastic crates in all the possible combinations under ambient conditions in first experiment. Under second experiment four types of sprout suppressant i.e., clove oil, mint oil, neem oil and tea tree oil with their three concentration i.e., 10 ml/litre, 15 ml/litre and 20 ml/litre were applied on potato tubers cv. Kufri Pushkar and stored in cardboard boxes for various parameters. The loss in weight of tubers due to physiological activities, decaying and sprouting increased with the increase in storage period. Dry matter content and specific gravity, reducing sugars, non-reducing sugar and total sugars also increased with increasing storage period. There was a marked reduction in phenol, ascorbic acid and starch content of potato tubers during storage up to the end of the experiment. Among the packaging materials, plastic crates showed the highest PLW (19.0 and 18.2%), whereas, LDPE bags the lowest (13.3 and 12.5%), decay loss was noticed highest in LDPE bags (49.7 and 47.7%) followed by cotton bags (36.4 and 38.1%) and sprouting loss was observed highest in plastic crates (83.3 and 15.0%), whereas, lowest in LDPE bags (55.1 and 7.2%) on 90th day of storage during first and second trial, respectively. Specific gravity showed non-significant difference with respect to packaging material but all the varieties showed their significant difference. LDPE bags showed highest value for ascorbic acid (14.54 and 16.21mg), phenols (26.57 and 25.93 mg) and dry matter (17.11 and 17.09%), whereas, plastic crates showed lowest value for ascorbic acid (11.79 and 10.96 mg), phenols (17.33 and 18.15 mg) and dry matter (16.12 and 15.77%) at the end of storage period in both year of storage study. Among the varieties, PLW was recorded highest in Kufri Bahar (16.97 and 15.54%), whereas, lowest in Kufri Pushkar (14.29 and 13.65%), decay loss was maximum in Kufri Pushkar (47.2 and 46.4%) while, minimum in Kufri Kufri Sadabahr (19.4 and 19.7%). So, far the variety is concerned, Kufri Sadabahar and among packaging materials, gunny bags followed by nylon netted bags showed overall better performance and Kufri Pushkar showed poor storage life. Amongst sprout suppressant, clove showed minimum PLW (8.13 and 7.79%), while, mint oil maximum (10.09 and 9.76%), tea tree oil showed lowest decay loss (31.62 and 28.31%), whereas, mint oil showed highest (37.47 and 37.41%). So far general appearance, tubers with different sprout suppressant showed sounded tubers than potato tubers under absolute control. Among anti sprouting agents, clove oil was significantly better while, among concentration, C2 and C3 showed better results for all the recorded parameters.
