Acetification of fruit juices generates different types of fruit vinegar with a variety of flavors and uses. In this study, Alcoholic juices fermented by employing Saccharomyces cerevisiae were subjected to acetification by pre-cultured Acetobacter pasteurianus PP21 at both 30 °C and 36 °C temperatures and they were tested for their Brix value, titratable acidity, alcohol content, antioxidant activity, phenolic content and flavonoid contents. Compared to the acetic acid production at 36 °C, both mango and jackfruit juices showed their peak acetic acid production of 4.5 ± 0.015% (w/v) and 4.2 ± 0.04% (w/v) respectively, at 30 °C. The final Brix value of mango and jackfruit juices subjected to acetification at 30 °C and 36 °C was found to be constant at 3.6, 5.7, and 3.1, 5.7 °Bx respectively. Furthermore, the final alcohol level of all the vinegar samples was found to be less than 0.5% (v/v). Moreover, the antioxidant activity, phenolic content and flavonoid contents of both mango and jackfruit juices after acetification were significantly higher (p<0.05) at 36 °C compared to vinegar produced at 30 °C. As per the results, both mango and jackfruit juices can be successfully used as a potential source of functional constituents in vinegar production at both 30 °C and 36 °C.","PeriodicalId":191739,"journal":{"name":"Tropical Agricultural Research and Extension","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115842802","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Agriculture plays an important role in improving the economic welfare of the Indonesian population. Research on the effect of agriculture on the Indonesians economic welfare has been widely carried out, while the effect of agriculture on the Indonesians happiness was still limited. This research aims to analyze the effect of GDP, agricultural GDP, and livestock GDP on Indonesians happiness. The study was conducted in January-April 2021. A regression model was applied with the dependent factor of the Happiness Index and independent factors of GDP, agricultural GDP, and livestock GDP of the Indonesians in 34 provinces in 2014 and 2017. GDP had no significant effect on the Indonesians happiness. GDP could be considered as one of the happiness components and should be combined with other indicators. Agricultural GDP had no significant effect on the Indonesians happiness. Agriculture was a producer of staple foods (basic human needs). When basic needs have been met and income has increased, the happiness was strongly influenced by non-material factors. Livestock GDP had no significant effect on the Indonesians happiness. Livestock was a producer of food sources of animal protein. For most Indonesians, animal food was still considered luxury goods with the characteristic that their expenditure for animal food was still very low.","PeriodicalId":191739,"journal":{"name":"Tropical Agricultural Research and Extension","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126830742","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study was aimed to understand the farmers’ perspectives on the spread of M. pigra in Matara district, Sri Lanka while uplifting awareness and estimating the distribution of the weed to support control activities. Semi-structured interviews with a pretested sample questionnaire survey were carried out among 400 randomly selected farmers among 16 Divisional Secretariats Divisions (DSDs) in the district. The spread areas of M. pigra were estimated using modern geospatial techniques, where images of unmanned aerial vehicle (UAV) (DJI Macvi Pro) were taken for mapping the affected area. UAV was captured 26.8 ha (5.84% of the total land area) of M. pigra invaded land extent in Akuressa and Malimbada DSDs. Based on the survey, 91.5 % of the farmers had no previous knowledge of controlling the particular weed. Approximately, 22.8% of the farmers expressed interest to establish Cinnamomum sp. as a perennial crop, and 11.8% suggested cultivating vegetables as the annuals in the areas invaded by M. pigra. The geospatial techniques used in this study was correctly identified the spread of M. pigra, which is very useful information for controlling weeds. Further research activities are suggested within the adaptive management framework and suitability of Cinnamomum sp. cultivation in M. pigra affected areas.","PeriodicalId":191739,"journal":{"name":"Tropical Agricultural Research and Extension","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129412689","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present practice is to allow fruits to ripen on the plant, however, it is believed that it may result in fewer fruits and low-quality seeds. Therefore, an experiment was conducted to identify the best maturity stage and the effect of postharvest ripening on the quality of eggplant seeds. Two eggplant varieties; Thinnavelli purple and Padagoda were grown and fruits were harvested at 35, 42 and 49 days after pollination (DAP) to determine the optimum harvesting time. Three postharvest ripening (PHR) periods (0, 1 and 2 weeks after harvesting) were also employed. Seeds from the fruits harvested at 35 DAP showed less germination %, vigour index and longer duration for 50% germination (T50). Germination percentage was increased up to 89% (Thinnavelli purple) and 72% (Padagoda) in seeds from fruits harvested at 35 DAP followed by 2 weeks PHR duration. Moreover, T50 was decreased from 1.74 to 0.94 days in Thinnavelli purple. The assessed seed quality parameters were much poorer in seeds from fruits harvested at 42 and 49 DAP. The results revealed that postharvest ripening enhances the seed quality of eggplant when fruits are harvested at the early ripened stage.","PeriodicalId":191739,"journal":{"name":"Tropical Agricultural Research and Extension","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127178866","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
