Bibliometric analysis of management practices in US corn (1990–2020)

AbstractBibliometric analysis explores large volume of scientific data, revealing trends and insights in a specific research field. Consistently, a bibliometric analysis of 30 years (1990–2020) was performed within the US corn (Zea mays L.) production using the Scopus database and VOSviewer. Search query was performed within the article title, abstract, and keywords indicative of management practices in corn. Exclusion criterion based on subject area and journals generated a total of 7468 publications. The data analysis revealed contributions from 7327 authors and 47 organizations documented in 69 journals. The top five organizations leading the investigation were United States Department of Agriculture – Agricultural Research Service, Iowa State University, University of Nebraska, University of Illinois, and Purdue University. The most prolific authors were Dr. Rattan Lal (Ohio State University, Columbus, OH), Dr. Douglas L. Karlen (USDA‐ARS, Ames, IA), Dr. Kenneth G. Cassman (University of Nebraska, Lincoln, NE), Dr. Lajpat Rai Ahuja (USDA‐ARS, Ft. Collins, CO), and Dr. John Walsh Doran (USDA‐ARS, Lincoln, NE). Journals with most publications were Agronomy Journal; Soil Science Society of America Journal; Soil and Tillage Research; Crop Science; and Agriculture, Ecosystems & Environment. Furthermore, author keywords differed from queried keywords, and no‐till, nitrogen, cover crop, soybean, irrigation, phosphorus, conservation tillage, yield, and water quality were most prominent. Moreover, there was an evident shift in keywords and an observed trend between 1998 and 2020. Overall, these findings allow researchers to explore network maps via the hyperlinks present in papers, identifying research gaps and advancing original studies to bridge gaps in the literature.

Introduction: Sustainability as an agroecological strategy toward resilience in agricultural systems

AbstractThe sustainability and resilience of agrifood systems are key concepts to ensure environmental standards in agriculture and food security. Recently, global food security has been seriously affected by the pandemics, geopolitical issues, and conflicts, and climate change factors have become a significant concern for scientists along with farmers, consumers, and citizens. To face these challenges, a systemic resilience in sustainable agriculture is pivotal. The research papers published in the special section of Agronomy Journal, “Agricultural and biological sciences: Plant, soil, animal and environment”, consider the role of sustainability in building greater resilience to current pivotal and diverse problems encountered in agricultural systems. This special section is a collection of coherent research studies that used a multidisciplinary approach. A total of 52 papers were submitted, of which 12 were accepted for publication following a double‐blind reviewing process. The purposes of the present paper were to identify the role of sustainability in the resilience of agricultural systems and to discuss the main results of these published articles. Results suggested that specific issues relevant to forests, crops, horticulture systems, and animal production could be improved and made more resilient by applying modern agricultural tools, efficient use of natural resources, and smart device technology. A sustainable intensification in a changing environment will require resilience at many levels. Key strategies identified included (i) improvement of resource efficiency; (ii) adoption of techniques that generate landscape‐scale resilience; and (iii) use of a combination of different evaluation and planning strategies to advance the knowledge of crop and livestock interactions.

Quadrat misuse: Confessions of a cover crop researcher's biomass sampling journey

AbstractRectangular quadrats (1 m2 or less) are commonly used in cover crop research to sample shoot biomass in fields where the cover crops are planted in narrow rows. However, in drilled cover crops, quadrats do not accurately estimate cover crop biomass unless the width dimension of the quadrat, that runs perpendicular to the rows, is a multiple of the cover crop row spacing. Illustrations are provided with correctly sized and placed quadrats for sampling drilled cover crops along with calculations to convert sampled biomass to field‐scale units. Examples with various quadrat sizes, row spacings, and quadrat placements are used to illustrate how researchers can inadvertently underestimate or overestimate biomass by up to 49% and 27%, respectively. A survey of 92 articles with cover crop biomass data published in the Agronomy Journal and Weed Technology from 2017 to 2021 found that many studies used an incorrect quadrat size, which suggests that they may have inaccurately estimated cover crop biomass. However, assumptions were made to reach this conclusion because only a few papers provided the dimensions, orientation, and shape of the quadrat used. These results (1) raise important questions about possible errors made in papers reporting cover crop biomass data and associated metrics (nitrogen uptake, weed biomass, etc.), and (2) highlight the need for describing sampling methods in greater detail to ensure that accurate data and analysis are published in the literature. Approaches to correct possible errors in published research are described along with biomass sampling suggestions for future cover crop research.

UMA ANÁLISE DE CLUSTER VIA CITESPACE A PROPÓSITO DE FERTILIZANTES (2008-2018)

The main objective of this work was to identify and analyze the international scientific production about “fertilizer” using bibliometric tools, referring to the period from 2008 to 2018. Thus, an exploratory-bibliographic study with a quantitative approach was carried out using the Web of Science (WoS) database as a search source, through the platform available on the CAPES website. A result of 28,282 publications was obtained, distributed in 45 journals, covering several areas of knowledge, with emphasis on: soil sciences (22%), environmental sciences (22%) and agricultural sciences (18%). The journal with the highest number of publications was the Agronomy Journal, with 737 papers, followed by Communications In Soil Science And Plant Analysis, with 702 publications. Chinese researcher Qirong Shen, from Nanjing Agricultural University, was the author with the most publications, 134 papers. Regarding the Institutions that produced the most, there was a predominance of universities from China and the USA, with the Agricultural University of China being the most prominent, with 585 records; followed by the Chinese Academy of Sciences University (CAS), with 563 records; and third, the Florida State University System, with 475 publications. Using the CiteSpace software, 62 clusters were mapped, worth highlighting six: Organic Fertilization, the largest cluster (65 references), Food security, the second largest cluster (57 references), followed by: Emission of N2O (52 references), Pasture (45 references), Biochar (24 references) and Bacterial community (6 references). This data mining for the period from 2008 to 2018, allowed us to conclude that: scientific production for fertilizer increased by 7.76%, on average per year, demonstrating the great importance of the topic before the scientific community, and not only that, also the its impact on humanity and on socio-economic and environmental policies.

Late-season nitrogen application increases grain protein concentration and is neutral for yield in wheat. A global meta-analysis

Late-season nitrogen (N) application has been proposed to boost grain yield and grain protein concentration (GPC) in cereals; however, its effects on bread and durum wheat have been inconsistent in field experiments. We performed a meta-analysis to (i) assess the effect of N applications to wheat after flag leaf visible (GS 37) on grain yield and GPC; and to assess the variation in these responses with (ii) N fertiliser management, (iii) environmental factors, and (iv) physiological traits. We searched ‘ Agronomy Journal ’, ‘ Crop Science ’, ‘ European Journal of Agronomy ’, and ‘ Field Crops Research ’ for articles published between 1980 and 2021 that allowed for a direct comparison of wheat yield and GPC between N application after GS 37 to an otherwise equally managed crop that received basal N fertilisation. We also collected other traits such as stover biomass and N uptake at plant maturity, and dough rheological properties, when available. The search resulted in 38 articles that, in addition to one unpublished trial from our group, evaluated 542 pairwise comparisons in 127 environments. Across studies, grain yield ranged from 1.15 to 10.63 Mg ha −1 and showed a negative relation with GPC, which ranged from 65 to 189 g kg −1 . Late-season N fertilisation was consistently neutral for grain yield (I 2 , proportion of the overall variance due to variation in real effects rather than chance, 26.2 %) and increased GPC with a pooled estimate of 3.96 %. The response of GPC was heterogeneous (I 2 = 84 %), suggesting the need for exploration of potential moderators of the response. Meta-regression suggested that increasing the proportion of late N relative to the total available N positively associated to increases in GPC, and the residuals of this analysis suggested that later applications increased GPC response, with no effect of N fertiliser source or placement. Environments with low temperature, high photothermal quotient, and long duration of the critical period associated with greater GPC response to late-season N applications. The relative response of GPC to late fertilisation correlated with the relative response of both stover N uptake and nitrogen concentration in stover at maturity, but not with stover biomass at maturity. Alveogram index and dough extensibility increased when late-season N increased GPC. Enhancing GPC through late N applications should consider associations between management, environmental, and physiological factors. Future research should focus on forecasting GPC response to late N, based on GPC response drivers identified in the current research. • Meta-analysis highlighted physiological drivers of wheat response to late N • Grain yield was unaffected by late N across a broad range of environments • Late N increased protein by 3.96% and its effects were heterogeneous • Protein increased linearly with the proportion of late N and with later applications • Higher protein response to late N associated to favourable growing conditions

What are the choices behind the titles? A Systemic Functional Grammar analysis of titles from articles of Rural Sciences and Communication

Selecting a text to read through its title is a current habit. In the scientific context, Swales and Feak (1998) explained that interesting titles attract readers and function as a way of convincing them to go forward. Previous studies usually present a quantitative approach. This research aims at identifying similarities and differences between titles of articles from Rural Sciences and Communication and providing an interpretation guided by Halliday and Matthiessen’s (2014) Systemic Functional Grammar. To do so, 246 titles were retrieved from the European Journal of Agronomy and the International Journal of Communication. Subsequently, an analysis of 30% of titles was conducted, considering the number of words, verbs, punctuation (HARTLEY, 2005), and field. The analysis suggests that titles are short, direct, and informative; choices for punctuation point to simple sentences, and the format short:long. The verbs were classified mainly as material processes, which may inform that concrete changes led to the article's findings.

Maize–soybean intercropping: A bibliometric analysis of 30 years of research publications

AbstractMaize (Zea may L.)–soybean [Glycine max (L.) Merr.] intercropping is popular in many countries because of its high productivity. However, no studies have explored maize–soybean intercropping via bibliometric methods. Taking the Web of Science database, the visualization applications of CiteSpace and VOSviewer were used to visually analyze the literature related to research in the field of maize–soybean intercropping, with the aim of studying keyword hotspots and evolving trends, and analyzing the future research directions. The results showed that the annual number of publications on maize–soybean intercropping showed rapid growth from 2010 to 2021. The top three publishing countries were China, the United States, and India, and the top three institutions were Sichuan Agricultural University, the Ministry of Agriculture and Rural Affairs of China, and China Agricultural University. Th three most popular journals were Field Crops Research, Agronomy Journal, and Indian Journal of Agronomy. Agronomy, multidisciplinary agriculture and plant science were the most popular research categories. A keyword analysis indicated that “maize” was the most popular study area. Crop root coupling processes, biological nitrogen fixation, efficient utilization of resources, carbon sequestration and emission reduction, microbial communities, and interspecific relationships are the current hot research topics. This study review and analyzed the current research hotspots and future research trends to provide an important reference for scientists to better respond to food security issues.

Physiological drivers of responses of grains per m2 to environmental and genetic factors in wheat

Most of the required increases in food production over the next decades are expected to be achieved through increases in crop yield. As wheat is essential for food security it is worrying that its yield gains over the last two decades were small. To achieve further yield increases it is critical to continue increasing number of grains per unit area (GN m -2 ), the trait best related to yield. In this context, it is relevant to identify the main determinants of GN m -2 in response to genetic and environmental factors as well as the trade-offs between them. In the present study we compiled a large database across the literature to analyse the relative importance of components when affected by genetic or environmental factors, producing small or large changes in GN m -2 and its components, either numerical (the number of spikes per m 2 , SN m -2 ; and the number of grains per spike, GN spike -1 ) or physiological (spike dry weight at anthesis, SDWa; and fruiting efficiency, FE) determinants. The database included 367 papers published in: (i) Field Crop Research (FCR), (ii) European Journal of Agronomy (EJA), (iii) Crop Science (CS) and (iv) Crop and Pasture Science (CPS, formerly Australian Journal of Agricultural Research) between 1990 and 2020. The complete dataset was split into classes, depending on the source of experimental variation, environment or genotype and was normalised to remove the differences between experiments and determine the environmental and genotypic effects within each experiment. Normalised data showed that the responsiveness of GN m -2 was similarly explained by changes in both SN m -2 and GN spike -1 , but in terms of physiological components SDWa was more relevant than FE for explaining the variations in GN m -2 . Considering the numerical components of GN m -2 genotypic and environmental factors modified more GN spike -1 than in SN m -2 . On the other hand, physiological components were differently modified by genotype and environment: for genotypic effects FE was more critical than SDWa and the other way around for environmental factors. A trade-off between numerical and physiological components was observed although was greater between physiological than between numerical components. • We quantified physiological/numerical components (and trade-offs) of grains/m -2 in wheat. • We recognised differences depending on magnitude and source of variation (genetic/environmental). • Grains/spike -1 explained better grains/m -2 than spikes/m -2 , particularly for genotypes. • Genotypes affected more fruiting efficiency than spike-dry-weight-at-anthesis, environments the opposite. • Trade-offs seemed more relevant for physiological than for numerical components.

Agricultural sciences and the environment: Reviewing recent technologies and innovations to combat the challenges of climate change, environmental protection, and food security

AbstractAgricultural production systems currently face multiple challenges: Climate change, natural resource depletion, and supply chain disruption, together with global population growth. As sustainable agriculture must simultaneously deliver myriad services (e.g. provide food security, maintain natural resources, retain and improve framers’ profitability, and sustain biodiversity), a systemic and multidisciplinary approach is thus needed. In this context, new technologies based on sensors, automatic machines, robots, and digital applications show much potential. The special section of the Agronomy Journal, entitled, “Agricultural and Biological Sciences: Plant, Soil, Animal and Environment Nutrient Management,” brings together a coherent set of research studies. All papers published in this special section address current, relevant topics for agriculture, biology and environmental sciences with a multidisciplinary approach aimed at generating new scientific information on digital technologies, bioinformatics, plant science, soil resources, agricultural waste, and environmentally conscious approaches. A total of 58 papers were submitted, each of which was evaluated by expert reviewers using a double‐blind reviewing process and 25 full text papers were accepted for publication in the special section. The present paper highlights the findings of the published papers, with the aim of bringing cutting‐edge innovation to applied research in agriculture and biology. The published papers here provide new knowledge and viable solutions for better performance in agricultural and biological sciences. New technologies will change the concept of farming and agribusiness making it more profitable, efficient, safer, attractive, simple, smart, and finally sustainable. Rural development and food security policies must support and finance the easiest possible access to new technologies for agricultural producers.

14th International Turfgrass Research Conference: Development and Sustainability

The turfgrass sector does not produce food or feed, but it is nonetheless important for a more sustainable future in agreement with the United Nations Sustainable Development Goals (SDGs) as outlined in Agenda 2030 (United Nations, 2015). Among the SDGs strongly related to the turfgrass sector are SDG 3 (good health and well-being), SDG 6 (clean water and sanitation), SDG 11 (sustainable cities and communities), SDG 12 (responsible consumption and production), SDG 13 (climate action), SDG 14 (life below water), SDG 15 (life on land), and SDG 17 (partnership for the goals). The present Volume 14 of the International Turfgrass Society Research Journal (ITSRJ) contains scientific and technical papers published in conjunction with the 14th International Turfgrass Research Conference (ITRC) to be held in Copenhagen, Denmark from 10 to 15 July 2022. The conference is organized by the Scandinavian Turfgrass and Environment Research Foundation (STERF) under the auspices of the International Turfgrass Society (ITS), and with ‘Development and Sustainability’ as the overarching theme. The ITS is a not-for-profit organization with the aim to encourage research and education in turfgrass science. Since its establishment in 1969, ITS’ main activity has been the ITRCs which are held every fourth year. The 14th ITRC was originally planned for July 2021 but had to be postponed to 2022 due to the COVID-19 pandemic. Research presented at the ITRCs were initially published as proceedings, but in 1993, ITS established ITSRJ with quadrennial volumes coinciding with the conferences. From Volume 13 (2017), the ITSRJ has been in digital format only. While ITSRJ is a fully refereed journal, its quadrennial status prohibits it from having an impact factor. For this reason, some of the papers to be presented at the 2022 ITRC have been published in special issues of Agronomy Journal (13 full papers; https://acsess.onlinelibrary.wiley.com/toc/14350645/2021/113/5) and Crop Science (28 full papers; https://acsess.onlinelibrary.wiley.com/toc/14350653/2021/61/5). The present main Volume 14 of ITSRJ contains 84 full papers and 37 short communications which have all been subjected to peer review by least two anonymous reviewers to ITS Standards and under the leadership of the seven Technical and 32 Associate Editors acknowledged on the following page. Nineteen Technical Papers are published in an Appendix to this main volume as they have not been subjected to a stringent peer review, but only a lenient check for language, avoidance of commercial aspects, and clarification of methods and results by ITSRJ Assistant Editor, Dr. Doug Soldat. Through a contract between ITS and the Alliance of Crop, Soil and Environmental Science Societies (ACSESS; ASA-CSSA-SSSA), who now partners with Wiley publishing company, authors, editors, and reviewers have enjoyed the great benefits of using Wiley's publishing platform for the current volume of ITRSJ. On behalf of the ITS, I would like to thank ACSESS and Wiley, and especially Ms. Elizabeth Gebhardt and Ms. Abby Morrison for their continuous support and collaboration during the 2-yr-long editorial process caused by the COVID-19 pandemic. I'm looking forward to meeting the international turfgrass community at the 14th ITRC in Copenhagen. I consider each paper published in this volume of ITSRJ and in the accompanying ITRC issues of Agronomy Journal and Crop Science as important contributions to the fulfillment of the overall aim of the conference: The development of a sustainable turfgrass sector for the benefit of a global society.

A pesticide in Franco's regime: communicating toxic risks in Spain, 1945-1975

This work analyzes the representations of the toxic risks of hexachlorocyclohexane, an active ingredient of many pesticides commonly used in Spanish fields during Franco's regime. Emphasis is placed on the practices that visibilized and invisibilized these risks, seeking to establish the actors that promoted them and the mechanisms they used. From the perspective of agnotology, I analyze the generation of ignorance and uncertainty related to this compound. Likewise, I examine the most prevalent rhetorical strategies used in print sources. To do so, I consulted three main primary sources: Boletín de patología vegetal y entomología agrícola, an agronomy journal for experts; Agricultura, a magazine for farmers, and ABC, a newspaper.
