Along with the current study, thirty-two different fennel genotypes and five local genotypes from Turkey were used to determine the morphological and yield properties in 2017 and 2018. A wide range of variation in plant height (39.22-129.60 cm), 1000 fruit yield (1.92-7.70 g), and fruit yield (0.12-8.68 g) was observed. As deduced from previous reports and from the current findings of the study, those relevant parameters could be considered for breeding purposes. To visualize or clarify the findings, a dendrogram was constructed to reveal the genetic variability regarding the morphological and yield properties of fennel genotypes. The dendrogram revealed that genotypes of different origins occurred in different groups, but local genotypes collected from Turkey occurred in the same group and subgroup. Additionally, correlation analysis was carried out to reveal the relationships between the relevant agronomic parameters. Of those correlation coefficients, a high correlation coefficient was noted between the number of fruits and fruit yield (r=0.849). Overall, the findings of the study revealed notable genetic variation related to fruit yield and other relevant agronomic traits for fennel genotypes, suggesting that this remarkable variation might be used for selecting superior genotypes in breeding programs. Of the genotypes analyzed, Ames30289 was the best genotype due to the highest fruit yield according to two successive years. Consequently, the findings can be considered useful information for fennel breeders, researchers and farmers in Turkey or other countries.","PeriodicalId":48477,"journal":{"name":"International Journal of Agriculture and Natural Resources","volume":"779 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71296407","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the lack of knowledge associated with its benefits and the lack of simple crop growth simulation models to determine its potential development, among others, has prevented its expansion. Transpiration-use efficiency (w) has been used to evaluate crop performance under different water supplies; however, the lack of consistency in w values under different environmental conditions has impeded its use as a transferable parameter. To overcome this problem, w is estimated through the normalized water-use efficiency (kDa) and the vapor pressure deficit (Da) as w = kDa Da-1, where kDa is a crop-dependent parameter. Therefore, the goals of this research were (i) to determine w and kDa in young plants of Opuntia ficus-indica and (ii) to compare the obtained parameters with values from other species. The w and kDa results were 18.57 (g kg-1) and 6.48 (g kPa kg-1), respectively. Here, w was more than two to six times the value for traditional cereals (maize, rice, wheat), while kDa was larger than that of most C3 crops and fell in the range for C4 and CAM crops. This is the first study that explicitly determines kDa for Opuntia ficus-indica; hence, more research should be carried out on its estimation, including under different agroclimatic conditions and in later stages of development. As a first approximation, the parameters obtained here can be used as a simple model to estimate yield projections of Opuntia ficus-indica.","PeriodicalId":48477,"journal":{"name":"International Journal of Agriculture and Natural Resources","volume":"1 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2021-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43205516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main goals of this research were to identify the temperature, pH, incubation time, and luminosity required for in vitro germination of H. vastatrix uredospores and to evaluate the effect of plant extracts on their germination. Uredospores from coffee plants (var. Caturra) grown in the state of Oaxaca, Mexico, were collected and subjected to treatments consisting of combined levels of T°, pH, and incubation time. The treatments were evaluated in darkness and under low-intensity white light (15 W). Uredospore germination occurred in the absence and presence of light. The highest percentage of uredospore germination was 44.95%, which occurred at pH 5.7, between 18 and 24 °C, and with an incubation time of 24 h. The effect of 30 plant extracts was evaluated in terms of inhibition of uredospore germination. The acetone and ethanol extracts of Tribulus terrestris, Datura ferox, Mansoa alliacea, Ricinus communis, and Acacia farnesiana inhibited 100% of uredospore germination. Thus, plant extracts may contribute to the integrated disease management of coffee leaf rust.","PeriodicalId":48477,"journal":{"name":"International Journal of Agriculture and Natural Resources","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2021-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45139349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sample consists of 346 French consumers of Chilean avocados in supermarkets of the Auvergne-Rhône-Alpes region. The main results show that the risk perceived by French consumers can only be related to the perceived extrinsic quality of the product. On the other hand, both perceived intrinsic and extrinsic quality are directly related to perceived value.

However, identifying effective policies that can achieve these goals remains elusive. In Chile, this sector has been one of the drivers of growth and poverty reduction but still faces many environmental and social challenges, and there is a growing public demand for achieving sustainability from an economic, environmental, and social perspective. Public and private institutions have made relevant efforts to increase Chilean agriculture sustainability.

Models that have enjoyed noticeable expansion are stochastic production frontiers for panel data. These models have proven very useful in total factor productivity (TFP) measurement and the analyses of its components. However, the related empirical literature in Latin America and the Caribbean has been limited, and a likely reason for this gap is data constraints. This article examines the setting surrounding the measurement and analysis of productivity in the Chilean agricultural sector. The specific objectives are to (1) provide a summary of key agricultural productivity measures and recent associated methodological advances; (2) present an overview of micro studies reporting technical efficiency and TFP in Chile; (3) portray the major sources of agricultural data available in the country; and (4) discuss salient features of the agricultural data systems used in Australia and the United States. The paper ends by identifying challenges and possible improvements to the prevailing data system that could strengthen the measurements and monitoring of productivity in Chile. The analysis suggests that the country needs substantial improvements in the collection and analysis of agricultural statistics to develop TFP and related research. This line of work is a critical step to enhance competitiveness and to foster adaptations to climate change, as well as to fully participate in efforts sponsored by the IFAD, FAO and the OECD to monitor progress toward the SDGs. On the positive side, several avenues are available to move toward a more robust agricultural statistical architecture.","PeriodicalId":48477,"journal":{"name":"International Journal of Agriculture and Natural Resources","volume":"1 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71295950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, irrigated surfaces contribute between 60 and 65% of the country’s agricultural GDP. Associated with Chile’s economic growth, total consumptive water use has increased, which, together with population growth, urbanization, water contamination and pollution, has led to important water stress situations that are triggering a greater number of conflicts and social, economic, and environmental vulnerability. The above phenomena will be exacerbated by climate change. At present, surface water deficit covering irrigation demands exists in the central and northern regions. This deficit is projected to increase as a result of climate change, which would increase the challenges for satisfying agricultural water requirements. The objective of this article is to integrally review the key aspects of Chilean water and agricultural water management policies, considering their interphases, providing the reader with a general overview of the main features of this model, an evaluation of its effectiveness and the main challenges agricultural water management faces. Resolving the challenges of the future requires a thorough reconsideration of water management policies and institutions and how water is managed in the agricultural sector in the broader context of overall water resource management in Chile.","PeriodicalId":48477,"journal":{"name":"International Journal of Agriculture and Natural Resources","volume":"1 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71295653","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
