The effect of 6 weeks of storage at 2.5, 5.0, 7.5, 10.0, or 12.5°C in a glass greenhouse was determined on 11 vegetatively propagated annual species. Fresh weight (total, shoot, and root) and height of 30 plants per species in each storage temperature were measured at the end of storage. Another 30 plants were transplanted into 15-cm pots (three plants per pot) and grown under natural light in a 20°C glass greenhouse for 3 weeks. Three species showed chilling injury or died during storage at ≤7.5°C. Plant height and shoot fresh weight at the end of storage for most species increased linearly as storage temperature increased. Storage temperature did not affect the net increase in height or weight significantly during recovery growth, except for plants that exhibited chilling injury at the end of storage.

Zingiber officinale is a tropical produce which is susceptible to chilling injury due to improper storage temperature management. Therefore, the objective of the study was to investigate the development of chilling injury (CI) in ‘Bentong’ ginger rhizome. Fresh ‘Bentong’ ginger rhizomes were harvested at 9-10 months and were stored at 5, 15 and 25°C for 0, 8, 16, and 24 days. The treatments were evaluated for the effects of storage temperatures and storage durations on postharvest chemical qualities of ginger rhizomes. The experiment showed significant interaction effects between storage temperature and storage durations for total flavonoid contents (TFC), total phenolic contents (TPC), 6- gingerol, 6-shogaol, and DPPH radical scavenging activity of the treated rhizome. Ginger stored at 15°C showed the highest TPC at 16 days of storage and then reduced throughout the storage as compared to the ginger stored at 5°C and 25°C. The 6-gingerol content increased from day 0 to day 16 and resulted in an optimum content at 66.7 mg/g fresh weight when it was stored at 15°C. 6-shogaol was identified in smaller quantities within the range of 1.52 to 3.11 mg/100 g of fresh weight. A similar trend was also observed in 6 -shogoal after 24 days of the storage. DPPH scavenging activity showed that storage at 5 and 25°C resulted in a decrease of DPPH inhibition along with storage durations. Therefore, it was suggested that the ginger was best kept at 15°C up to 16 days of storage in order to maintain the postharvest qualities and chemical properties of ginger.

Studies were conducted over three seasons to determine the relationship of temperature and humidity on the storage life of fresh cranberry (Vaccinium macrocarpon Aiton) fruit. Each year, cranberries harvested from four commercial bogs were stored at temperatures ranging from 0 to 10 °C in combination with relative humidities (RH) ranging from 75% to 98%. Fruit were stored under these conditions for up to 6 months and were evaluated monthly for marketability, decay, physiological breakdown, weight loss, and firmness immediately after removal and after an additional week at 20 °C. The percentage of marketable fruit declined substantially over time in all storage conditions with 41% to 57% becoming unmarketable after 2 months as a result of both decay and physiological breakdown. Relative humidity had a greater effect on fruit storage life than temperature and after 5 months, the amount of marketable fruit stored in high (98%) and medium (88%) RH was 71% and 31% less than that stored in low (75% to 82%) RH. Rates of fresh weight loss increased as RH in storage decreased and was 0.41%, 0.81%, and 0.86% per month in fruit stored in high, medium, and low RH, respectively. Fruit firmness was not significantly affected by RH. The effects of storage temperatures ranging from 0 to 7 °C on marketable fruit after 2 to 5 months of storage were not significant. Only fruit stored at 10 °C consistently had fewer marketable fruit when compared with fruit stored at lower temperatures. Storage temperature had no significant effect on decay incidence. However, physiological breakdown was greatest in fruit stored at 10 °C. Rates of fresh weight loss increased with storage temperature, ranging from 0.35% to 1.17% per month for fruit stored at 0 to 10 °C, respectively. Contrary to previous reports, no evidence of chilling injury was found in cranberry fruit stored at 0 °C. Results suggest that cranberry fruit should be stored at 0 to 7 °C and 75% to 82% RH to retain marketable fruit.

Solid organic fertilizing for organically sweet corn production should be combined with foliar application to improve fertilizing effectiveness. Each sweet corn variety had different response to particular liquid organic fertilizer (LOF). This experiment aimed to determine growth and yields of three sweet corn varieties to local-based LOF was conducted at CAPS research station (950m above sea level) from March to June 2015, arranged in a factorial completely randomized block design with three replicates. The first factor was three sweet corn varieties, i.e. Talenta, Jambore and Asian Honey, and the second factor was five LOF concentrations,i.e. 0, 25, 50, 75, and 100 ppm, respectively. Results indicated that sweet corn varieties significantly affected plant height, plant leaf area, root fresh-weight,weight of husked ears, weight of unhusked ears, but did not affect diameterof unhusked ear and shoot fresh weight. LOF concentrations did not affect all observed parameters. So did the interaction between varieties and LOF concentrations, except on shoot fresh-weight. Asian Honey variety had the highest plant height, plant leaf area, roots fresh-weight, weight of husked ears, and weight of unhusked ears. There were no different in plant diameter and shoot fresh weight among the tested varieties. Further research should be focused on the use of higher concentration of local-based LOF to provide effective complementary organic fertilizing in sweet corn production.

Mango fruits `Criollo de Bocado' harvested at the mature-green stage were treated with a hydrothermic treatment of 55 °C for 3 min and stored for 20 days to temperatures of 10 ± 2, 15 ± 2, and 28 ± 2 °C. A randomized design 2 × 3 × 4 with three replications was used. Physical parameters such as color (L*, a*, b*), firmnness, and fresh weight loss were studied. Results reported that mango fruits stored at 10.2 and 15.2 °C showed the highest firmness values. Skin color changed very fast during the first storage days, while pulp color required more time to achieve mature ripe color. Fresh weight loss tended to increase with storage time and with high storage temperature. The lowest storage temperture retarded softening in mango fruits and firmnness reached the highest values.

Navel oranges are reportedly susceptible to postharvest peel disorders, including chilling injury and aging/stem end rind breakdown. These and other physiological disorders are sometimes given the common term “navel rind breakdown.” California citrus industry reports on recent incidences of navel rind breakdown suggested that some instances of this disorder were similar to “postharvest pitting,” a disorder that we have observed in a number of Florida citrus varieties. Thus, we decided to define the morphology and etiology of pitting of `Washington' navel orange (Citrus sinensis L.) peel. The disorder was characterized by the collapse of clusters of oil glands and was stimulated by wax application and high temperature (≥13 °C) storage. Internal ethanol levels of waxed fruit stored at high temperature (13 or 21 °C) were significantly higher among fruit that developed pitting than those that did not. The pitting observed in these studies is comparable to previously observed navel orange disorders that have occurred without known cause. Navel orange pitting is morphologically and etiologically distinct from chilling injury and aging/stem end rind breakdown, but is similar to postharvest pitting of Florida citrus fruit.

Three trials were undertaken to study storage conditions and handling procedures required to maximise the postharvest storage life of honeydew melons (Cucumis melo L. var. inodorus Naud.).Honeydew melons treated with chlorine (1000 mg/L), benomyl (250 mg/L) + guazatine (500 mg/L), shrink wrap (17 ym Cryovac XDR film), Semperfresh, wax, or combinations of these treatments were stored at 4 or 8�C, for 4 or 6 weeks. Benomyl plus guazatine reduced the development of storage rots associated with Alternaria and Fusarium spp. The use of shrink wrap and wax reduced water loss by melons but increased fungal infection in some cases. Shrink wrapping combined with the fungicide treatment effectively reduced the incidence of fungal breakdown in the storage period for up to 4 weeks. Wax coating with full strength Citruseal wax caused anaerobic tissue breakdown. Melons were affected by chilling injury at 4�C. Control of bacterial rots with benomyl + guazatine or with chlorine was variable. Semperfresh did not reduce the incidence of fungal breakdown or water loss from the melons. The results indicate that storage of honeydew melons for 4 weeks at 8�C by pretreating with fungicide is possible but the melons soften and rot after 6 weeks, making them unsaleable. Four weeks should be adequate to allow for sea freighting of honeydew melons to markets in South East Asia. Further research is required to determine the optimum storage temperature for honeydew melons.

Potential development of medicinal plants in Karanganyar is very large, because this area is famous as a center of medicinal plants such as ginger, turmeric, kencur, and temulawak. In the development of medicinal plants, the approach of organic cultivation is one of the alternatives that can be done to achieve the business. Therefore the application of technology to society about organic farming on Biopharmaca Cluster of Karanganyar was conducted with the aim to apply organic cultivation techniques that have resulted from previous studies, so it can be applied by the community to increase income and welfare. This application of technology to society activity is held in Sambirejo, Jumantono, Karanganyar. The research was conducted from March to October 2016. The results showed that the application of chicken manure affects the number of leaves, number of tillers, and the fresh weight of turmeric rhizome. The addition of manure (chicken, goat, cow) can increase all variables of planting growth which include plant height, number of leaf, number of tillers, fresh weight of plant, dry weight of plant, and fresh weight of rhizomes. Giving three types of manure (chicken, goat, cow) with mycorrhizal dose treatment there is no intraction to some growth observation variables. Mycorrhizal treatment with a dose of 10 g/plant can increase the number of tillers in turmeric. Overall the application of mycorrhizal at various doses (5, 10, and 15 g/plant) can increase plant height, leaf number, number of tillers, and fresh weight of turmeric rhizome.

The paitan plant contains allelopathic compounds for other plants so that the utilize of paitan plant as a source of liquid organic fertilizer (LOF) has not been widely applied. This research aimed to study the interaction between LOF dosage and appropriate application method of LOF to increase the growth of kailan plants. The research conducted at experimental garden of UIN Bandung from June-August 2016. The experimental design was a completely randomized design with two factors and replicated four times. The first factor was application methods (A), i.e. a1=direct application to the soil, and a2= spraying. The second factor was LOF dosage (T), i.e. t0: 0 ml plant-1, t1: 20 ml plant-1, t2: 40 ml plant-1, t3: 60 ml plant-1, t4: 80 ml plant-1. The growth parameters observed i.e. plant height (14, 21, 28, 35 and 42 Day after Transplanting (DAT)), leaf area 42 DAT, plant dry weight 42 DAT, and plant fresh weight 42 DAT. The data then analyzed with analysis of variance at a significant level of 5%. If the analysis of variance was significant, the Duncan multiple range test was used at α=5%. The research results showed there was no interaction between method of application with a various dosage of paitan LOF to all of the growth parameters. The application paitan LOF showed similar growth in terms of plant height, leaf area, plant dry, and plant fresh weight. The application method of paitan LOF direct to the soil or spraying to leaves can not increase kailan plant growth.

The effect of several strategies - alone and integrated - on the control of the Phytophthora sp. fungae, which causes radical rotting of papaya fruits, was evaluated under nursery conditions. The experiment took place between August 1994 and March 1995 at the University of Costa Rica's Estación Experimental Fabio Baudrit, located in Alajuela, Costa Rica. The treatments applied were: sun heat for 30 days; organic fertilizer made from hen droppings; etridiazole fungicide; and the following combinations: sun heat + etridiazole + organic fertilizer; etridiazole + organic fertilizer; sun heat + etridiazole; sun heat + etridiazole + organic fertilizer, and finally, an inoculated control treatment. Soil rows were made, and then they were innoculated with the pathogenic agent, and finally the aforementioned treatments were applied. The treated soils were bagged separately. The Solo Sunrise Hawaiian variety was planted in bags. The percentage of gerrnination, stem diameter at soillevel, plant height, radical system fresh weight, and severity of radical rotting were evaluated three months later. In addition, the effect of the treatments on beneficent soil microorganism populations (actinomyces, protozoa, bacteria, and fungi) was evaluated, as well as those of pathogenic populations. Organic fertilizer increased plant strength. All treatments affected germination; the innoculated control had the greatest germination percentage. Treatments containing organic fertilizer affected germination most.
