    (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%.

    Studies on effect of salicylic acid, putrescine and modified atmospheric packaging of guava (Psidium guajava L.) cultivar Hisar Safeda
    (CCSHAU, Hisar, 2021-09) Gurpreet Singh; Malik, Arvind
    Guava fruits are highly perishable in nature, necessitating strategies to enhance post-harvest life in order to extend fresh fruit market period. Therefore, the present investigations were conducted to explore the possibilities of storage of guava cv. Hisar Safeda in refrigerated and ambient conditions with treatments of salicylic acid, putrescine and different modified atmospheric packaging. The fruits harvested at physiological maturity stage were subjected to the treatments of salicylic acid (1 mM, 2 mM, 3 mM and 4 mM), putrescine (2 mM, 3 mM, 4 mM and 5 mM) and different modified atmospheric packaging (LDPE, HDPE, Polypropylene and cellophane paper), packed in CFB boxes and stored in refrigerator and ambient conditions. The fruits were analyzed for various parameters on alternate days. Under both the storage conditions, all the treatments exhibited potential to maintain the post-harvest life of guava fruits as compared to control. However, higher concentrations of salicylic acid and putrescine are effective in reducing physiological loss in weight, decay loss and retaining a higher level of total soluble solids (TSS), TSS: Acid ratio, sugars, ascorbic acid and pectin content, which helps in maintaining acceptable quality and improving the shelf-life of guava cv. Hisar Safeda in refrigerator as well as ambient storage. The best overall results were found in fruits treated with salicylic acid @ 4 mM followed by salicylic acid @ 3 mM under refrigerator storage. Also, modified atmospheric packaging (MAP) with HDPE 25 micron was found to extend the shelf-life and maintain the better quality of guava during storage and proved to be the best MAP treatment. Hence, salicylic acid, putrescine and HDPE seems have the potential to enhance the post-harvest life of guava in refrigerator as well as ambient storage.

    (CCSHAU,HiSAR, 2020-08) Reddy, Gajjala Chandra; Goyal, R.K
    A field experiment entitled “Effect of biofertilizers in combination with nitrogen, phosphorous and organic manure on growth, yield and quality of strawberry cv. Winter Dawn" was conducted during the year 2017-18 and 2018-19 at hi-tech greenhouse of the Department of Horticulture, CCS Haryana Agricultural University, Hisar. The investigation composed of three experiments viz., (i) effect of biofertilizers in combination with nitrogen on growth, yield and quality of strawberry, (ii) effect of biofertilizers in combination with phosphorous on growth, yield and quality of strawberry and (iii) effect of organic manure in combination with biofertilizers on growth, yield and quality of strawberry. The experiment-I comprised of four levels of nitrogen, i.e., 0, 80, 100 and 120% recommended dose of nitrogen (RDN) and two biofertilizers viz., Azotobacter and Azospirillum. Nitrogen levels and biofertilizers in combination had significant influence on growth parameters such as plant height, spread, number of leaves, crown diameter and fresh and dry weight of plants. The maximum fruit yield parameters and quality traits were recorded with 100% RDN along with biofertilizers. The leaf NPK content was recorded higher in 120 and 100% RDN along with biofertilizers than control treatment. The experiment-II comprised of four levels of phosphorous, i.e., 0, 80, 100 and 120% recommended dose of phosphorous (RDP) along with two biofertilizers, i.e., vesicular- arbuscular mycorrhiza (VAM) and phosphate solubilizing bacteria (PSB). All the possible combinations of phosphorous and biofertilizers were found to have significant influence on vegetative growth, yield and quality parameters of strawberry. The minimum number of days taken to first flowering, maximum fruit weight, size and fruit yield per plant were recorded with 100% RDP along with VAM. TSS and ascorbic acid were noted maximum with combined application of 120% RDP and biofertilizers. The leaf NPK content was significantly higher in 120% RDP along with biofertilizers than the control treatment. The experiment-III comprised of nine treatments, viz., T1: Sand: FYM (3:1), T2: Sand: FYM (2:1), T3: Sand: Vermicompost (3:1), T4: Sand: Vermicompost (2:1), T5: Sand: FYM (3:1) + Azotobacter, T6: Sand: FYM (2:1) + Azotobacter, T7: Sand: Vermicompost (3:1) + Azotobacter, T8: Sand: Vermicompost (3:1) + Azotobacter and T9: Control (Sand). The results indicate that manure in combination with Azotobacter treated plants had better vegetative growth, yield and quality than the control.
