    Studies on effect of post-harvest treatment on shelf life of pomegranate (punica granatum L.)
    (CCSHAU, Hisar, 2020-08) Bebe Lima Naderi; Sharma, Jeet Ram
    The experiment comprising of KMnO4 1, 1.5 and 2%, beal leaf extract 10, 20 and 30% and Aloe vera gel extract 10, 20 and 30% were conducted at Post-harvest Laboratory of the Department of Horticulture, CCS Haryana Agricultural University, Hisar to evaluate the best and the most effective post-harvest treatment for prolonging shelf life and maintaining physicochemical characteristics of high valued pomegranate fruits cv. Bhagwa and Mridula. In this experiment, all the post-harvest treatments proved effective in increasing the shelf life and improving the physico-chemical attributes of the fruits of cv. Bhagwa and Mridula over control. However treatment with KMnO4 2% was most effective in reducing fruit firmness, specific gravity, physiological loss in weight, diseases incidence and decay loss. Different quality attributes like TSS, pH, TSS/acid ratio, anthocyanin, total sugars, reducing sugars and non-reducing sugar of fruits increased, while juice content, ascorbic acid and acidity decreased with the advancement of storage period under ambient room conditions. Among the treatments, KMnO4 2% treated pomegranate fruit had least content of TSS and sugars and significantly highest content of juice, anthocyanin, ascorbic acid and pH but had no effect on acidity of the fruits. Hence, the highest organoleptic rating was given to pomegranate fruits treated with KMnO4 2%.

    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.

    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.
