Also, previous research on farmers' repayment of agricultural credit emphasized that a high default rate is a growing concern, thereby becoming a tall order for financial institutions to lend to farmers. Similarly, past studies accentuate an increasing focus on socio-economic characteristics as factors that explain the repayment rate. The nexus between repayment rates and credit rationing has not been well analyzed. The effect of credit rationing on repayment rate was therefore investigated. The study, therefore, investigates the causal effects of credit rationing on loan repayment performance using a structured questionnaire to elicit information from selected 240 respondents via a three-stage method of sampling technique, and the instrumental variable Tobit technique to analyze the effect of credit rationing on repayment performance. The result showed that the majority (70.83%) of the respondents are males, the mean age was 51 years with an average education year of 12.65. The result of instrumental variable Tobit regression confirmed the endogeneity of rationing rate (Wald test of exogeneity = Wald Chi2 (1) = 67.26; Prob > chi2 = 0.000) at a 1% level of statistical significance. The result with a Log-likelihood function (265.62459) revealed that the ration rate, among others, with coefficients of 0.4335, was a crucial factor in ascertaining the rate of repayment at various significant levels of the arable crop farmers in the research area. The key finding is that credit rationing did have a significantly positive influence on agricultural credit repayment. The research concluded that the significance of credit rationing in influencing the likelihood of repayment rate, points to the vital significance of adequacy in rationing borrowers.","PeriodicalId":44793,"journal":{"name":"AIMS Agriculture and Food","volume":"1 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70183059","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}

To atomize the powder, we used a Buchi mini spray-dryer B-290 with three inlet temperatures (140, 160 and 180 ℃) and a laboratory freeze dryer with a −0.8 bar pressure for 4 days. During atomization, the powders presented lower moisture content and water activity with the addition of maltodextrin; however, there were no significant changes in the moisture of the freeze-dried powders. Colorimetric analysis revealed that the luminosity (L) and chroma (C) values changed as maltodextrin concentration increased. The structures of particles were examined by scanning electron microscopy (SEM) SEM, and very different morphological characteristics resulted from the two drying methods. Also, apparent density, hygroscopy and dissolution testing revealed significant differences between the powders. Sangorache antioxidant compounds were preserved to a greater extent by applying low concentrations of the encapsulating agent and by the freeze-drying technique. The natural colorant from sangorache inflorescences could serve as an additive to improve food color in the industry.","PeriodicalId":44793,"journal":{"name":"AIMS Agriculture and Food","volume":"1 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70183404","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}

Moderate, convenience-pursuing and quality-pursuing categories are separated by cluster analysis. Consumer attitudes toward ready-made meals and takeaway meal solutions, perceived consequences of purchasing organic food, purchase frequency and quantity are differential, and the influence of organic food purchasing perception of consequence on altruistic behaviour are differences in CFL. Only consumers who purchase organic food motivated by environmental concerns are able to improve their recycling behavior.

Despite this, the degree of perception and adaptive attitude of farmers to climate change is still quite limited, especially in smallholder family farms in the Mediterranean areas. This study explores the level of perception of climate change by PDO (Protected Designation of Origin) winegrowers in a region of southern Italy (Sicily) and the adaptation actions able to cope with climate change, using a nonparametric approach. The analysis is based on data collected through self-administered questionnaires submitted to 380 PDO winegrowers. For variables comparison the Mann Whitney and the Kruskall Wallis test were applied according to the number of compared samples (two or more independent samples, respectively). Results show how winegrowers' perceptions of climate change tends to vary according to age and education of the respondents and to altitude and size of vineyards. This study highlights how information and dissemination of knowledge among winegrowers play a strategic role in the perception of climate change, especially in rural and remote Mediterranean areas.","PeriodicalId":44793,"journal":{"name":"AIMS Agriculture and Food","volume":"1 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70183498","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}

VF is developing at a rapid speed with great market potential and opportunities. Environmental pollution and consumersx increased awareness of a healthy lifestyle drive Chinese people to seek \"safety, healthier and clean\" food more than anyone else in the world. The increasing gross domestic product enables more and more people to afford VF-produced products. The great market opportunities have attracted many domestic and international investors to join the market. Until 2020, there were more than 200 plant factories operating in China, and the number is increasing. Nevertheless, the development of vertical farms is in the initial stage in China, which can be summarized as follows: 1) the high investment and operational costs are the main barriers to profitability; 2) technology development still lags behind other VF-advanced countries, such as in the development of intelligent crop management equipment; 3) insufficient government support, as promoting a vertical farm market requires more efficient political and financial support from the Chinese government; and 4) consumer public awareness of VF is too low.","PeriodicalId":44793,"journal":{"name":"AIMS Agriculture and Food","volume":"1 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70183595","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 technique involved a study of the coffee bean drying process parameters, such as temperature (35, 45 and 55 ℃), airflow (100 m3/min∙m2) and thickness (0.2 m) for mechanical drying, vs conventional drying in the open sun until 11% of moisture content was reached. For mechanical drying, the effective diffusion coefficient, electrical conductivity and drying kinetics were evaluated. A sensory test was performed for three storage periods (3, 6 and 9 months) using the Specialty Coffee Association (SCA) protocol. The results showed that the effective diffusion coefficient varied from 3.21 to 8.02 × 10−7 m2/s for mechanical drying and from 4.21 × 10−11 m2/s for drying in the open sun. The time drying time was established at 20.35 ± 0.06, 29.10 ± 0.09 and 71.52 ± 0.11 hours for mechanical drying at 55 ℃, 45 ℃ and 35 ℃ respectively and 54.48 ± 11.37 hours for drying in the open sun system. The average moisture content at the end of all drying operations was 12.5%. Electrical conductivity rose from 11.71 to 16.86 µS/cm∙g at drying temperatures ranging from 35 to 55 ℃. The sensory test revealed that storage duration had no effect on the quality of the coffee drink when in touch with the drying process, with mechanical drying yielding higher sensory ratings. The coffee beans were dried at 55 ℃, yielding coffee samples with SCA scores more than 85 points. In overall, it is determined that the convective mechanical drying method is a viable approach for the processing of specialty coffee beans since it allows for the retention of high-quality sensory qualities, allowing it to command higher market pricing.","PeriodicalId":44793,"journal":{"name":"AIMS Agriculture and Food","volume":"1 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70183606","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}

Its burning leads to the loss of an energy valuable resource and causes enormous environmental damage. An environmentally friendly and promising biotechnological process for such waste utilization is the production of mushrooms for food and medicine. However, the energy intensity of substrate preparation hinders the development of work in this direction. Another significant challenge in this field is to increase the biological efficiency of substrate processing. The purpose of our investigation was to reveal the contribution of microorganisms to solving this and other problems of mushroom cultivation based on a review of the latest scientific research on the topic. The literature from databases of Google Scholar, Scopus, and Web of Science was selected by various combinations of search queries concerning mushrooms, substrates, microbial communities, and their effects. The current state of the issue of mushrooms and microorganisms' interactions is presented. The review considers in detail the contribution of microorganisms to the substrate preparation, describes microbial communities in various phases of the mushroom cultivation process, and identifies the main groups of microorganisms associated with lignocellulose degradation, mushroom growth promotion, and protection against pathogens. The significant contribution of bacteria to mushroom cultivation is shown. The review demonstrates that the contribution of bacteria to lignin degradation in lignocellulosic substrates during mushroom cultivation is largely underestimated. In this process, various genera of the bacterial phyla Bacillota, Pseudomonadota, and Actinomycetota are involved. The correct combinations of microorganisms can provide controllability of the entire cultivation process and increase required indicators. However, expanding research in this direction is necessary to remove gaps in understanding the relationship between microorganisms and mushrooms.","PeriodicalId":44793,"journal":{"name":"AIMS Agriculture and Food","volume":"1 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70183718","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}

Consequently, an urgent imperative arises to explore technological advancements that can boost food production in alignment with the growing demands. The Soilless Production System (SPS) emerges as a proficient approach for managing irrigation water, thereby making a significant contribution to food security. This research focuses on the efficient use of SPS and identifies the best economic use of the soilless techniques for different crops within an area characterized by limited land and water availability. The database for the study was generated through a farm survey to investigate the benefits of adopting SPSs as a sustainable agricultural practice. A linear programming approach was applied to develop an optimization model for resource allocation and crop mix selection, considering the development opportunities through the SPSs. Different scenarios were applied in the model. The results proved that adopting SPSs is a sustainable irrigation practice, since the technique promotes water use efficiency, generates profitability, and conserves the associated natural resources. The SPSs ensure sustainable use of water resources by increasing water use efficiency. The hydroponics cultivation system had 11 ± 1.7 times higher yields but required 82 ± 11 times more energy in comparison to the lettuce crop produced by the conventional production system (CPS). The result of the optimal solution shows that the total revenue of scenarios of the study is 109% of the revenue of the original value of the largest farmer. The water resources and the investment cost as constraints in the model are totally used, but the operational costs in the optimal solutions are 74% of the total operational cost in the original data.
