The major postharvest limit is weight loss and yellowing of peel color due to transpiration and respiration. An experiment was conducted to assess the influence of coconut oil, bee wax coating, and sealed packaging on post-harvest storage quality and shelf life of lime at cold storage. Limes were harvested at 147 days after fruit setting. Sorted limes were washed and dried using a fan and then coated with coconut oil and bee wax mixture with the respective ratios of 90:10, 80:20, 70:30 and 100:0 percentages. After coating, limes were kept in 17.5 cm x 17.5 cm size with 150 gauge perforated polyethylene bags and sealed polyethylene bags which served as Modified Atmospheric Packaging (MAP) and then stored at cold conditions (60C, RH 40%). The effectiveness of edible coating and sealed bag in extending the shelf life of lime and fruit quality was evaluated by determining weight loss, firmness, surface color, and juice content which were assessed periodically during storage. The results revealed that 100% coconut oil treatment and 90:10 bee wax coating, especially with a sealed bag, had an immense effect on retaining green colour, reducing weight loss and shrivelling and preserving firmness and moisture content of lime performing better storage life for 56 days of storage.","PeriodicalId":514605,"journal":{"name":"Journal of Food and Agriculture","volume":" 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141826399","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}

As a result, organic farming has become a debatable and timely valuable topic in Sri Lanka. Organic farming is an agricultural farming method that applies environmentally friendly pest and weed control mechanisms and fertilizers derived primarily from animal and plant wastes, as well as nitrogen-fixing cover crops. This study focused on analysing how farmers’ general attitudes, behavioural beliefs, favourable attitudes toward fully organic farming, subjective norms, and perceived behavioural control influence the adaptation to fully organic vegetable farming in Polonnaruwa district. A questionnaire survey was conducted by face-to-face interviews to gather primary data from a randomly selected sample of 300 farmers from the vegetable sector in the Polonnaruwa district. The data were analysed using Confirmatory Factor Analysis through AMOS in the SPSS 24 version. The results revealed that the farmers’ perceptions of the adaptation to fully organic vegetable farming are significantly and negatively influenced by general attitudes, behavioural beliefs, favourable attitudes towards fully organic farming, subjective norms, and perceived behavioural control among farmers in the Polonnaruwa district. Findings are important for policymakers and relevant organizations when implementing the agriculture policy in the country.","PeriodicalId":514605,"journal":{"name":"Journal of Food and Agriculture","volume":" 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141827451","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}
