Abstract A climate-resilient, root-based sweetpotato planting material (SPM) conservation method called “Triple S” or “Storage in Sand and Sprouting” has created timely access to sweetpotato planting material in areas with a prolonged dry season in Uganda and Tanzania. The aim of this study was to validate and optimize the Triple S method for conservation of sweetpotato planting material in dry areas of southern Ethiopia. The Triple S method was validated in four districts of southern Ethiopia on varieties Kulfo and Awassa 83 and compared with two common local planting material conservation methods: leaving “volunteer roots” in the soil which then sprout at the onset of rains; and planting vines under shade or mulch. Across study locations and for both varieties, Triple S resulted in a higher survival rate (81–95%) in storage during the dry season compared to the local conservation methods (7–57%). Plants of both varieties grown from roots conserved with the Triple S method showed significantly higher vine growth and lower weevil and virus infection symptoms compared to plants grown from the two local conservation methods. An additional experiment found that planting at the start of the main rainy season in June and harvesting just before the start of the dry season in October gives the highest number of medium-sized and weevil-free roots suitable for Triple S. The current study demonstrated that the Triple S method is a promising technology for small-scale sweetpotato farmers in dry areas for timely access to high-quality planting material

Abstract The green revolution and climate change have become a promising Indonesian rice production strategy to reach self-sufficiency through the application of improved agricultural technology such as organic rice farming (ORF). ORF is an eco-friendly agricultural practice that increases production, income, and sustainable agriculture. This study assessed farmers’ perception, motivation, constraints, awareness, and belief in adopting ORF. The study used a multi-stage sampling procedure. The primary data were collected from 203 households in West Java Province using a structured questionnaire. Weighted average index (WAI) was used to assess the farmers’ perception, motivation, awareness, and belief regarding the adoption of ORF. The results reveal a significantly different perception between ORF and conventional rice farming (CRF) farmers on production, quality, health and safety, market price, environmental concern, and certification aspects. ORF farmers had a more positive perception than conventional farmers. The results of the WAI reveal that CRF had a lower yield (0.63), risk-averse (0.70), and no cash compensation (0.62), whereas ORF had a higher price (0.82) and organic farming lifestyle (0.83). The ORF farmers also still have a strong positive belief in organic farming for the future, even though they lack organic fertilizer resources and certification. The strategies for adopting ORF are infrastructure improvement and community empowerment, compensation and incentive strategy, more intensive socialization, provision of assistance and training related to ORF, marketing facilitation, and subsidies on the prices and certification of organic rice.

Abstract Pearl millet (Pennisetum glaucum (L.) R. Br.) is a valuable agronomic and industrial promising crop with high adaptation potentials considered as understudied species and is not attributed the interest it deserves. This investigation reports for the first time the transferability of barley nuclear microsatellites to pearl millet genome. This allowed the inference of the considerable potential of transferability of the nuclear simple sequence repeats (nSSRs) mapped from Hordeum vulgare L. genome to P. glaucum species. Out of the 42 tested SSRs, ten were found to be transferable, giving a transferability rate of 23.8%. These latter markers enabled the molecular characterization of the nine barley and nine pearl millet autochthonous landraces and revealed high levels of polymorphism and discriminatory powers. All the microsatellites were proved to be highly informative with an average polymorphic information content value of 0.74. The gene diversity index revealed a high level of diversity encompassed in both germplams with a mean H e value of 0.80. At the species level, comparable amounts of genetic variability were detected for H. vulgare and P. glaucum landraces. Furthermore, the set of ten transferable nSSRs exhibited high ability in revealing the genetic structure, differentiation and phylogenetic relationships among the studied germplasms. The new available nSSRs present an additional informative and discriminant set of molecular markers which will be useful in further genetic studies concerning the multipurpose species P. glaucum L. such as molecular fingerprinting, genetic purity assessment, genome mapping, marker-assisted breeding and conservation programs.

Abstract To increase the competitiveness of chocolate and cocoa drink on the market, innovation of the products is substantially required. Incorporation of additional ingredients, i.e., ginger and cinnamon, as well giving information intervention on their health effect may increase the consumer acceptance as well as advance the consumer perception on the products. This study, therefore, aims to determine the effect of additional ingredient and intervention on health-related information on the hedonic level, emo-sensory response and collative perception of panelists on milk chocolate and cocoa drinks, which were enriched with additional ingredients, i.e., ginger, cinnamon and stabilizers. This study used descriptive quantitative method in which the data were obtained from 40 panelists. Correspondence analysis was used to see the emo-sensory profile and panelist perceptions that were emerged from each sample. The results show that the addition of spices to chocolate and cocoa drinks resulted in a statistically significant decrease in the hedonic level. However, the use of stabilizer significantly improved the hedonic level of cocoa drink. The hedonic responses, emotions and collative perceptions of the panelists were influenced by the product information, particularly on the products with the addition of spices.

Abstract The European Union Farm Accountancy Data Network (FADN) publishes data for the representative farms of several European Union (EU) farm types, regions and countries. In this database, the published data for the farm types allow us to assess several agricultural policies. In fact, the FADN publishes data for the EU farming types and there are not many studies about these fields in the whole European context. This study aims to bring novelty for the whole spectrum of stakeholder types in these domains. The analysis of these impacts may bring relevant insights, especially, for adjustments in the design of future strategies and plans. We analyse the evolution of the EU farm types in the last two decades with significant scenario changes like two large common agricultural policy (CAP) reforms (2003 and 2013) and suggest new approaches to the design for future measures. Statistical information from the FADN over the period 2004–2018 is considered. In addition, efficiency and productivity assessments are carried out, to assess the implications of the most recent instruments of the CAP. The results show that the policy instruments in the framework of the 2013 CAP justify the use of more inputs (or at least at higher costs) for the same level of output. In fact, the subsidies given to the farmers since 2014 mask the inefficiencies underlying some farm types. A significant decrease in the total factor productivity confirmed this trend, despite positive growth rates for the total verified output for several farm types over the period.

Abstract The land is one of the determining factors for sustainable agriculture. However, attention to the protection of agricultural land in economic development has not fully sided with the interests of agricultural development in the long term. The conversion of agricultural land because of the growth of the industrial and service sectors has displaced agricultural land, making this a serious problem for the existence and sustainability of agriculture. This study aims to analyze the willingness of farmers to maintain sustainable food agricultural land (SFAL) in the Special Region of Yogyakarta. This study can contribute thoughts in the formulation of sustainable agricultural development policies. The survey was conducted on rice farmers at 25 observation points from eight irrigation source rivers spread across the Special Region of Yogyakarta. A total of 125 rice farmers were taken at simple random as the sample of this study. The determinants of farmers’ willingness were analyzed using binomial logistic regression. The results of the analysis show that education, the distance to irrigation sources, rural areas, farm income, and access to credit are factors that influence the willingness of farmers to maintain SFAL, especially rice plants. Therefore, it is important for farmers to maintain sustainable food fields through various programs such as extension, farming credit, production price incentives, and the provision of good irrigation facilities.

Abstract Science plays an important role in the development of agriculture. Publication activity is one of the factors in the assessment of science intensity in certain areas. Evaluating the number of articles on a specific topic in a certain period can indicate a trend in developing science in the country and international cooperation. Agricultural science in Russia lags far behind leading topics such as chemistry and physics, especially in international cooperation. This article aimed to assess the publication activity in Russia in the area of agriculture to analyze the development of agricultural science in the country and the impact of the national project “Science” on the trend of change. The authors used the Web of Science Core Collection database for this study and analyzed 7,436 papers on the topic of agriculture co-authored by Russian and foreign authors. This study showed the number of articles by year, research areas, and distribution publication records in collaboration with other countries. The article results showed that agricultural science has been growing in a general trend in recent years. The most significant increase in the overall publication in agriculture topics and cooperation occurred after the project “Science” was launched. The project showed a great impact on publication activity in Russia.

Abstract Between 2005 and 2015, the forest area occupied by maritime pine trees in Continental Portugal decreased by about 10.6%, and the existing volume decreased by about 18.4% mainly due to fires and pests (e.g., nematode) that occurred during this period. The purpose of this study was to study the evolution of the land use environmental impact of 1 m3 of maritime pine, standing in Portuguese forest, during that period using the model by Milà i Canals based on soil organic matter measured by soil organic carbon. Results show that the land use impact category increased from 16,812 kg C deficit in 2005 to 18,423 kg C deficit in 2015. Land transformation to forest roads is the main contribution for land use impact representing 54% of the total value followed by land occupation as forest that represents about 40%.

Abstract The possible future challenge for food agriculture development led to the transition from conventional to modern agricultural management using smart farming technology (SFT). Some factors detaining the use of SFT for food commodities, specifically in small farmers’ communities, are global climate change, low-quality human resources of farmers, and extension workers. Small farmers generally have relatively small land, limited access to capital and farming input, and grow different kinds of commodities according to seasons. This research examined the adoption readiness in using SFT for three food commodities in Aceh Province, Indonesia, namely rice, maize, and potatoes. The sample comprises 70 farmers per commodity and 48 extension workers, obtained through the quota sampling method, culminating in 258 respondents. The readiness measurement for SFT adoption was conducted by introducing various models, images, videos, and RITX applications. The collected data were investigated and analyzed using the Mann–Whitney and Kruskal–Wallis for two or more categories. The result showed that both farmers and extension workers have a positive perception of the application of SFT. However, in terms of readiness, farmers have a relatively lower readiness level than the extension workers due to their low capacity. This means it is essential to focus on the economic and capacity building of farmers by providing them with appropriate SFT devices to overcome the high investment cost and provide the technical skill for its application to overcome this situation.

Some factors detaining the use of SFT for food commodities, specifically in small farmers’ communities, are global climate change, low-quality human resources of farmers, and extension workers. Small farmers generally have relatively small land, limited access to capital and farming input, and grow different kinds of commodities according to seasons. This research examined the adoption readiness in using SFT for three food commodities in Aceh Province, Indonesia, namely rice, maize, and potatoes. The sample comprises 70 farmers per commodity and 48 extension workers, obtained through the quota sampling method, culminating in 258 respondents. The readiness measurement for SFT adoption was conducted by introducing various models, images, videos, and RITX applications. The collected data were investigated and analyzed using the Mann–Whitney and Kruskal–Wallis for two or more categories. The result showed that both farmers and extension workers have a positive perception of the application of SFT. However, in terms of readiness, farmers have a relatively lower readiness level than the extension workers due to their low capacity. This means it is essential to focus on the economic and capacity building of farmers by providing them with appropriate SFT devices to overcome the high investment cost and provide the technical skill for its application to overcome this situation.","PeriodicalId":45740,"journal":{"name":"Open Agriculture","volume":"7 1","pages":"857 - 870"},"PeriodicalIF":2.3,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45328484","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}
