Energy budgeting, carbon footprint and economics of sunflower and pigeonpea system under moisture conservation practices in rainfed semi-arid tropics

In drylands, soil water availability in the profile during crop period, especially at critical stages is most vital. System which is productive, energy efficient with a minimum carbon (C) footprint under limited water condition is a concern. Therefore we evaluated sunflower and pigeonpea crops over two-years in terms of productivity, energy, C-footprint and profitability under different moisture conservation measures. These were raised bed, ridge and furrow, tied ridges and furrow, conservation tillage, flatbed sowing and opening furrow after every three rows at 30 days, and flatbed sowing under sole crops of sunflower and pigeonpea and intercropping at 1:1 adopted split-plot design. The results showed in-field moisture conservation by ridge and furrow produced considerably greater sunflower (59.6–66%) and pigeonpea (85.2–128.7%) yields and profitable (604.1 US$ ha−1) over traditional flatbed sowing. It also exhibited greater output energy (37.8–83.0%), energy use efficiency(4.2 kg GJ−1),and lower energy intensity (21.57 × 10−3 GJ US$−1). Sunflower and pigeonpea sole crops produced higher seed yields over intercropping. But it has yield advantage in terms of greater pigeonpea equivalent yield (0.53–1.13 Mg ha−1), profitability (691.8 USD ha−1), output energy (42.4 GJ ha−1) and energy ratio. Among the input energy sources, chemical fertilizers accounted 53.6 % of the total input energy. Interestingly, least C-footprints were recorded under ridge and furrow (182 kg CE kg−1grain)and intercropping (0.248 kg CE kg−1 grain). Results confirmed sunflower and pigeonpea intercropping on ridge and furrow was productive, energy saving, C-footprint reduction and economical practice under rainfed condition.

Technological choices and practices of Early Bronze Age pottery production in the Central Plains: Focusing on the sites of Xinzhai and Huadizui

Aspects of the Early Bronze Age (ca. 2050–1640 BCE) pottery production technology and knowledge transfer in the Central Plains of China (i.e., the Zhengzhou-Luoyang area) were studied. To this aim, 120 domestic pottery samples and ten geological samples from two central sites at Xinzhai and Huadizui were studied macroscopically and analysed with X-ray fluorescence spectrometry. Based on a discussion of macroscopical evidence and chemical composition, the results tentatively indicate the technological knowledge transfer between the potters in Xinzhai and Huadizui sites despite being located about 80 km apart. Pottery of the same category was manufactured with similar selection and preparation strategies of ceramic raw materials, decorated with similar patterns, and adopted similar forming techniques. More specifically, the cookware from the Xinzhai and Huadizui sites was hand-made and Ca-poor, while the storage- and drinking wares were wheel-made and Ca-rich. These results likely indicate the existence of one overarching community of practice, potters located at Xinzhai and Huadizui, who shared strategies for raw materials selection, paste preparation, and finishing.

Assessment of surface irrigation potential and crop water demand in Daramalo Wereda, southern Ethiopia

AbstractAssessing available water and land resources as well as their potential for surface irrigation use is vital for sustainable agricultural development and planning. Agricultural irrigation also plays a crucial role in ensuring food security and reducing poverty in Ethiopia. However, it is dominated by rain‐fed agriculture, with rainfall distribution and intensity vary spatially and temporally. Enhancing agricultural water management and irrigation has the potential to increase agricultural productivity. The objective of the study was to evaluate surface water potential and the irrigation water demand of Zage River sub‐watershed, which were estimated using hydrological model of Soil and Water Assessment Tool (SWAT) and CROPWAT8.0 software, respectively. Slope, soil type, drainage densities, land use/cover, and river proximity were the factors utilized to determine irrigation land suitability. A weighted overlay was completed, with 17.32% of irrigable lands found to be highly suitable, 41.29% moderately suitable, 37.61% marginally suitable, and 3.78% not suitable. The SWAT model result gave very good model performance indicator values of NE = 0.773 and R2 = 0.872 for calibration and NE = 0.771 & R2 = 0.945 for validation. The SWAT model result showed a total of 33.248 million m3 of surface runoff generated annually. Compared with irrigation water demand of 21.068 million m3, this suggests the watershed has high surface water potential for surface irrigation for selected crop types of the watershed. The findings of this research are relevant to improving local water management policies and practices and enable stakeholders to make decisions that enhance agricultural productivity and sustainable agricultural practices and help ensure the food security of local farmers.

The LTAR Grazing Land Common Experiment at Platte River High Plains Aquifer.

The Long-Term Agroecosystem Research (LTAR) network of the United States Department of Agriculture (USDA) consists presently of 18 sites within the contiguous United States that are managed by the Agricultural Research Service (ARS) and its partners. The LTAR network focuses on developing national strategies for more efficient, resilient, and profitable agricultural production systems, improved environmental quality, and enhanced rural prosperity. The Platte River High Plains Aquifer (PRHPA) LTAR site is managed jointly by the University of Nebraska-Lincoln (UNL) and USDA-ARS and is one of the LTAR sites that conduct research on both integrated cropping and grazing systems. The PRHPA region encompasses multiple land resource areas and diverse agricultural production systems. The PRHPA sites, predominantly located in eastern Nebraska, are designated as an integrated system focused specifically on the region's dominant production practices of row crop (corn and soybean), managed pastures, and beef cattle production. Here, we focus on C3 cool-season smooth bromegrass (Bromus inermis Leyss.) pasture grazing systems under prevailing and alternative management practices for the region. The sites evaluate continuous and rotational grazing with and without pasture fertilization (prevailing practices). In an additional treatment, cattle are supplemented with dry distillers grains plus solubles, while manure supplies fertilization (alternative practice). Main measurements at the site evaluate plant and animal productivity, forage quality, greenhouse gas fluxes, and soil physical, chemical, and biological properties. This paper describes the regional characteristics of the PRHPA site, ongoing LTAR research related to pasture and livestock production, stakeholder engagement, and future research plans.

Characterization, generative design, and fabrication of a carbon fiber-reinforced industrial robot gripper via additive manufacturing

Robot grippers are crucial components across various industrial applications, requiring special design and production for obtaining the optimal performance. Conventional plastic injection moulding techniques fall short in achieving the specificity needed for these grippers. To address this challenge, current paper focuses on developing a robot gripper using carbon fiber-reinforced polyamide with a next-generation composite filament and employing the innovative Generative Design technique. In the work, we began by characterizing and optimizing the composite material specifications. Then, the tensile strength and fracture mechanics of standard samples based on printing parameters, applying Taguchi experimental design for optimization were evaluated. Analysis of Variance (ANOVA) was used for factor analysis to fine-tune the process. Using the Generative Design technique, we determined optimal geometries, which were then fabricated through Fused Deposition Modeling (FDM). As a result, the optimization efforts led to significant improvements i.e., tensile strength increased from 103.2 to 116 MPa, and the elasticity modulus from 8386 to 8990 MPa. In practical industrial applications, we achieved a reduction in material weight from 14 to 4 g, lowered production costs from $5.16 to $1.50, and cut production time from 58 to 28 min. This study presents a validated method for developing industrial products with reduced material usage and costs, promoting sustainable production practices.

Drivers of the food system based on food sovereignty domains: an integrative systematic literature review

Food sovereignty, as defined by the comprehensive definition offered in the 2007 Nyéléni Forum, encompasses essential action lines for transforming a food system based on food sovereignty principles. Understanding how current food system initiatives align with these principles is essential for identifying the necessary processes of change to drive this transformation. This study aimed to consolidate the contributions of advancements in food sovereignty to the existing literature. A systematic literature review was conducted to achieve this, analyzing 250 papers published between 2008 and 2023. The focus was on the research methods employed by the authors, food initiatives within the domains of food sovereignty, and the key drivers of a food system rooted in food sovereignty principles. The findings revealed that approximately 36% of the studies utilized interviews, surveys, and questionnaires for data collection, while 34% concentrated on targeted fieldwork through case studies. Around 19% of the studies involved in-depth interaction with specific groups, and just under 10% employed document analysis methods. The most extensively discussed domain was the use of agroecological management practices for food production, followed by the valuation of traditional knowledge, the promotion of social justice and equity, self-determination through the transformation of economic and political institutions, and the localization of food production and consumption. The food initiatives outlined overarching goals within each domain of food sovereignty, with three common goals identified across these domains: food security and consumption, environmental stewardship, and crisis preparedness. Furthermore, 29 drivers of a food system based on the domains of food sovereignty were identified, encompassing networks and a holistic approach present in all 5 domains. The study also highlights the implications for supporters of food sovereignty within the context of the identified goals of the food initiatives.

Review of the facilitators and barriers to adoption of biofortified foods and food products.

Biofortification - the process of increasing the concentrations of essential nutrients in staple crops - is a means of addressing the burden of micronutrient deficiencies at a population level via existing food systems, such as smallholder farms. To realise its potential for global impact, we need to understand the factors that are associated with decisions to adopt biofortified crops and food products. We searched the literature to identify adoption determinants, i.e. barriers to (factors negatively associated) or facilitators of (factors positively associated) adoption, of biofortified crops and food products. We found 41 studies reporting facilitator(s) and/or barrier(s) of adoption. We categorised the factors using the Consolidated Framework of Implementation Research 2.0, resulting in a set of factors that enable or constrain adoption of biofortified foods across twenty-four constructs and five domains of this meta-theoretical determinant framework from implementation science. Facilitators of orange sweet potato adoption included knowledge about importance, relative advantage, efficient production and management practices; barriers included lacking timely access to quality vines and market remoteness (28 studies total). Facilitators of vitamin A cassava adoption included awareness of its benefits and access to information; barriers included poor road networks and scarcity of improved technology including inadequate processing/storage facilities (8). Facilitators of high-iron bean adoption included farmers' networking and high farming experience; barriers included low knowledge of bean biofortification (8). Barriers to vitamin A maize adoption included low awareness and concerns regarding yield, texture and aflatoxin contamination (1). These barriers and facilitators may be a starting point for researchers to move towards testing implementation strategies and/or for policymakers to consider before planning scale-up and continuous optimisation of ongoing projects promoting adoption of biofortified crops and food products.

Language teachers’ emotions in online classrooms: Relations among teachers’ appraisals of classroom events, emotional responses, and instructional practices

Drawing upon Frenzel’s (2014) framework of appraisals, the current study explored language teachers’ emotional experiences and their antecedents in the online teaching context. Moreover, the interrelations between teachers’ emotions and their instructional practices were also investigated. Data were collected through semi-structured interviews with eleven language teachers from a top-tier international university in China. Our findings revealed that positive appraisals of online classroom events, including goal attainment, the capacity in and responsibility of effectively delivering lessons online, and the importance teachers attached to online teaching, tended to result in positive emotional experiences, which consequently led to motivational stimulations in more creative and productive instructional practices. By contrast, teachers who had negative appraisals of online teaching events tended to experience more unpleasant emotions and emotional vulnerability, which would possibly impede effective instructional practices and steer their teaching towards more traditional teaching methods. Our study contributes to the understanding of the relations among teachers’ appraisals of classroom events, emotional experiences, and instructional practices in online language classrooms. Implications for how to prepare teachers emotionally for online teaching are also discussed.

Chemical characteristics of Salix psammophila sand barriers are accelerated degradation by ultraviolet irradiation and water.

The implementation of Salix psammophila sand barriers measures constitutes a crucial element in desertification control, providing a solid theoretical foundation for the future application and pretreatment of sand barriers in production practices. To address the specific damage types predominant in desert environments, we executed simulations of ultraviolet irradiation and rainfall phenomena on mechanical sand barriers in sandy areas and also inspected the variations in chemical properties during accelerated aging processes. The findings unequivocally demonstrate that: (1) The synergistic impact of ultraviolet irradiation and water accelerated the deformation and fracturing of the S.psammophila sand barriers, thereby causing a partial degradation of its chemical properties and conspicuous lignin oxidation; (2) The fissure of the sand barrier deepened, resulting in structural alterations. The existence of water expedites the degradation process of S.psammophila sand barriers under ultraviolet irradiation. (3)With respect to the binding form of C atoms, the carbon atoms at S.psammophila sand barriers were highly oxidized after 576 hours of accelerated aging. The components of C2 (C-O) and C3 (C=O) rising to 40.16% and 12.24% respectively, while the components of C1 (C-C) declined to 47.60%. The amount of hydroxyl (O-C-O), carbonyl (C=O), and carboxyl (O-C=O) groups increases in line with the expansion of the contact area between the sand barrier structure and ultraviolet irradiation as well as water. More free radical substances are generated, thereby causing the chemical binding properties to tend to be more stable. In summary, Ultraviolet irradiation and water change are the primary factors influencing the degradation of S.psammophila sand barriers material structure and properties. In future desertification control, it is imperative to focus on enhancing the longevity of sand barriers by ensuring their waterproofing capabilities and resistance to ultraviolet irradiation.

Socio-economic Impact Assessment of Salinity Prevention Structure-Bardasagar Scheme in Porbandar District of Gujarat, India

India's vast coastline, spanning 7,516 kilometers, faces a critical challenge of seawater intrusion, resulting in salinity issues that profoundly affect agriculture, water resources, and socio-economic well-being. Among the coastal states, Gujarat, with its extensive 1,600-kilometer coastline, bears a significant burden of this phenomenon. The Barda Sagar Prevention Scheme aims to mitigate these effects by managing water resources effectively, thereby reducing salinity impact in the Porbandar area of Gujarat and ensuring the well-being of local communities. The Barda Sagar Scheme, situated in Rinavada village within Porbandar taluka of Gujarat, stands as a vital initiative aimed at addressing these challenges. This study meticulously evaluates the scheme's impact on agriculture, livestock, and rural livelihoods in both upstream and downstream villages. The findings underscore the scheme's substantial positive influence on various facets of rural life. Significant shifts in cropping patterns and agricultural land usage, accompanied by notable increases in crop yields, particularly in principal crops like groundnut and cumin, demonstrate the scheme's efficacy in enhancing agricultural productivity. Moreover, changes in livestock population, production, and feeding practices suggest potential improvements in livestock management and productivity, despite some fluctuations in livestock populations. Access to safe drinking water, a fundamental aspect of rural livelihoods, has witnessed considerable improvement due to the scheme's implementation. Increased reliance on the Narmada pipeline and enhanced access to potable water across surveyed villages reflect positive strides in water security and overall living standards. However, the study also identifies various challenges and factors influencing the observed changes. Soil degradation, pest incidence, and the need for sustainable water management strategies emerge as notable challenges that require ongoing attention and intervention. While positive drivers such as increased rainfall and improved market access have facilitated progress, continued monitoring, and adaptive management remain imperative for ensuring the scheme's long-term sustainability and efficacy.

A contextual approach to decolonising IR: Interrogating knowledge production hierarchies

Abstract Although calls to decolonise International Relations (IR) have become more prominent, the endeavour becomes infinitely more complex when searching for concrete approaches to decolonise IR knowledge production. We posit that decolonising IR, a global counter-hegemonic political project to dismantle and transform dominant knowledge production practices, must be enacted according to context-specific particularities. Contexts shape practices of epistemological decolonisation, since knowledge hierarchies are enacted and experienced – and must be challenged and dismantled – differently in different sites. Yet although acknowledged as important, contexts are understudied and under-theorised. This raises several questions: how do contexts matter to IR knowledge production, in what ways, and with what effects? This article disaggregates six contexts in IR knowledge production – material, spatial, disciplinary, political, embodied, and temporal – and explores how they impact academic practices. We bring together hitherto-disparate insights into the role of contexts in knowledge production from Global IR, Political Sociology, Feminist Studies, Higher Education Studies, and Critical Geopolitics, illustrating them with empirical evidence from 30 interviews with IR scholars across a variety of countries and academic institutions. We argue that an interrogation of the inequalities produced through these contexts brings us closer towards developing concrete tools to dismantle entrenched hierarchies in IR knowledge production.

Digital Methods: An STS Challenge to Methodological Digitization in Social Science Research

ABSTRACT The integration of digital technologies into social science has catalyzed the development of fields such as digital sociology, digital humanities, and digital social sciences more broadly. This technological shift has significant methodological implications for social science research, which are being increasingly discussed. This discussion raises critical questions about the potential and limitations of merging traditional social research methodologies with digital innovations. Digitized and digital methods have brought about promises of a new era in social science research. However, some scholars have highlighted the challenges and limitations associated with this methodological transition, including data-relevant considerations, skill and expertise issues, and ethical concerns. From the vantage point of advancements in science and technology studies (STS) – a discipline that has engaged with the methods and practices of knowledge production for some decades – I will explore five additional methodological challenges posed by the digitization of social science research that has been largely overlooked or neglected in the literature of digital methods. Our analysis concludes that while digital methods can serve as valuable complementary tools, they are not sufficient to fully engage with the core practices and phenomena of social science research. Thus, digital and traditional methods can coexist, albeit not in a symmetrical manner.

Review on spontaneous imbibition mechanisms in gas-water systems: Impacts on unconventional gas production and CO2 geo-sequestration

Spontaneous imbibition, a fundamental process in porous media, involves the displacement of a non-wetting phase by a wetting phase driven by capillary pressure. It plays a key role in various applications, particularly in unconventional gas production and greenhouse gas geo-sequestration. Despite extensive research in this area, conflicting results and explanations persist regarding imbibition phenomena, particularly in gas-water systems. This paper aims to address this gap by providing a comprehensive review of basic concepts, mechanical analyses, pore-filling patterns, front evolutions, and influencing factors associated with spontaneous imbibition. Mechanical factors including capillary force, viscous force, gravitational force, hydrostatic force, inertial force, capillary back force, and dead end force, play crucial roles in water imbibition with different boundary types. The pore-filling pattern significantly affects microscopic fluid distribution and front evolution during the imbibition process. To resolve conflicting findings, we systematically analyze the influencing factors of spontaneous imbibition within gas-water systems, encompassing rock properties, fluid characteristics, rock-fluid interactions, and reservoir properties. Furthermore, we present an in-depth discussion on the imbibition and trapping mechanisms relevant to unconventional gas production and CO2 geo-sequestration, providing insights into force analyses and influencing factors. Gas production strategies and favorable conditions for CO2 capillary trapping are proposed. Finally, we outline existing knowledge gaps and suggest potential directions for future research. This review thus provides useful insights and suggestions for advancing our understanding of spontaneous imbibition within gas-water systems and optimizing unconventional gas production and CO2 geo-sequestration practices.

Patterns of variation and relationships among fat, protein, and milk yield of individual dairy cattle in a Thai multibreed population.

This study systematically examines the patterns of milk yield (MY, kg), fat (FAT, %), and protein (PROT, %) in a diverse population of Thai multibreed dairy cattle, considering the tropical environment's impact on lactating cows. Using a dataset of 47,205 monthly test-day records from 4,440 first-lactation cows across 446 farms, we analyze variations and interrelationships through mathematical averaging and introduce the fat-to-protein ratio (FPR) to assess acidosis (FPR < 1.1) and ketosis (FPR > 1.5) risks during lactation. Pearson correlation analysis elucidated trait associations. The findings, aligned with established lactation norms, indicate peak production at 297 days in milk (DIM) for FAT (4.08%; SD = 0.96%), PROT (3.43%; SD = 0.47%), and 52 DIM for MY (18.09kg; SD = 4.91kg). Nadirs are observed at 72 DIM for FAT (3.27%; SD = 0.74%), 47 DIM for PROT (2.86%; SD = 0.36%), and 299 DIM for MY (9.05kg; SD = 2.95kg). FPR variations highlight acidosis (46.48%), normal (43.66%), and ketosis (9.86%), especially during early lactation (100 DIM). Significant negative correlations emerge between MY, FAT, and PROT (P < 0.05), while a positive correlation is identified between FAT and PROT (P < 0.01), with robust correlations during early lactation. This study contributes to understanding tailored nutritional strategies for dairy cows' holistic health and sustainability in tropical environments, guiding efficient production practices and mitigating health-related productivity impediments.

Unveiling the Nutritional Quality of Terrestrial Animal Source Foods by Species and Characteristics of Livestock Systems.

Background. It is well-established that a range of macronutrients, micronutrients and bioactive compounds found in animal-source foods play unique and important roles in human health as part of a healthy diet. Methods. This narrative review focuses on terrestrial animal source foods (TASFs). It particularly analyzes five groups: poultry eggs, milk, unprocessed meat, foods from hunting and wildlife farming, and insects. The objectives were as follows: (1) examine the nutrient composition of TASFs within and across livestock species, drawing on the country and regional food composition databases; (2) analyze the influence of intrinsic animal characteristics and production practices on TASF nutritional quality. Results. TASFs are rich in high-quality proteins and fats, as well as micronutrients such as vitamin B12, iron or zinc. This study found differences in the nutritional quality of TASFs by livestock species and animal products, as well as by characteristics of livestock production systems. Our findings suggest that there may be public health opportunities by diversifying TASF consumption across species and improving certain aspects of the production systems to provide products that are both more sustainable and of higher quality. Conclusions. Future research should adopt a more holistic approach to examining the food matrix and the dietary patterns that influence TASF digestibility. It is necessary to include meat from hunting and wildlife farming and insects in global food composition databases, as limited literature was found. In addition, scarce research focuses on low- and middle-income countries, highlighting the need for further exploration of TASF food composition analysis and how intrinsic animal characteristics and livestock production system characteristics impact their nutritional value.

Recent developments in second home research: has the COVID-19 pandemic spurred a re-thinking of second home mobilities?

ABSTRACT This paper explores whether the COVID-19 pandemic has initiated a “re-thinking” of second home mobilities globally. For a long time, second homes have mainly been seen as a leisure space and part of tourism consumption in rural areas in contrast to more productive, entrepreneurial and residential functions and practices. We claim that the pandemic has pinpointed second homes’ increasingly integrated role in everyday life practices, including being spaces for productive and regenerative ends, such as work, safety and health. Furthermore, the importance of second homes within a wider mobility framework is also highlighted, where second homes should be seen as not only a type of tourism mobility. In this paper, we carry out a literature review that aims to expand from the well-established tourism, rural studies and geography perspectives on second home mobilities and connect second homes to identify new research pathways which have been highlighted during the pandemic. By doing so we will pinpoint the growing avenues and future directions for second home research.

Educating Dora: Teaching a conversational agent to talk

Many organisations are witnessing the introduction of automated systems to mediate between them and their clients, often designed as dialogic user interfaces which are conversational in nature. Despite calls for the design of AI-powered conversational agents to draw on Ethnomethodological Conversation Analysis (EMCA), how an EMCA-informed conversation design can improve interactions between humans and conversational agents is yet to be empirically examined. This paper reports on a collaboration between EMCA researchers and AI conversation designers at digital health company Ufonia to develop Dora, a pre-existing ‘automated clinical assistant’ that provides telephone consultations for patients of the UK’s National Health Service. Our analysis identified differences between the conversation design of the product and conversational practices found in equivalent activities involving human clinicians, relevant to implementing changes to improve user experience. We demonstrate that users are prompted to recalibrate their practices (such as for turn-taking) in situ as they engage with a system which does not match their prior experiences of this activity type. Such insights can be leveraged to adapt system design so that it more closely approximates users’ prior experiences of such engagements.

Transformation of the farm segment of the aquaculture value chain in southern Bangladesh

Aquaculture in Bangladesh has experienced rapid growth over the last three decades, yet technological changes in the farming segment remains underexplored. To address this gap, we surveyed 721 farmers across seven districts in southern Bangladesh from November 2020 to February 2021. The result showed moderate growth in aquaculture, with an 11 % increase in farmers and a 15 % rise in waterbodies over the past decade. Farmers cultivated diverse aquatic species, with carp dominating production at 56 % followed by crustaceans (16 %) and tilapia (14 %). Shrimp are more highly susceptible to disease than fish and prawn but, only 19 % of farmers adopted measures to enhance survival. The study noted a shift from shrimp to prawn and from crustaceans to fish due to disease, market demand, and environmental factors, resulting in intensification and greater use of floating feed over the last decade. A mere 0.55 % of farmers reported losses, spoilage, or wastage during harvest or between harvest and sale of aquatic products, with the volume being minimal at just 0.52 %. Farming generated 401,536 full-time equivalent (FTE) on-jobs in the seven surveyed districts, predominantly for family labor. Aquaculture demonstrates strong profitability, with an average benefit-cost ratio (BCR) of 1.98, indicating nearly a twofold return on investment. This study highlights the evolving dynamics of aquaculture in southern Bangladesh, revealing modest growth, increased species diversification, and shifts in production practices, which underscore the sector's profitability and need for improved technological adoption on a global scale.

A Current View on Strawberry Production Practices and Trends in the Northeastern United States and Canada

Strawberries (Fragaria ×ananassa) are an important crop for diversified fruit and vegetable farms in the northeastern United States as well as in Ontario and Québec, Canada. The industry in this cold climate region differs greatly from that in the major strawberry-producing states of Florida and California because strawberries typically represent a smaller share of total farm revenue and are sold primarily through retail markets. In recent years, strawberry production and marketing methods in the northeastern United States and Canada have diversified to meet the unique challenges of the region, including regional demand, extended seasons, and management of an increasingly challenging pest and disease complex. In 2020, we distributed an online survey to 163 commercial producers to obtain a snapshot of marketing and production practices used on strawberry-producing farms in this region and to assess research and outreach needs to better serve the industry. We conducted in-depth case study interviews with a small number of producers after the survey. We found that traditional June-bearing strawberry production continues to represent &gt;50% of production, and that most fruit are grown conventionally. Day-neutral strawberry production was reported by an increased number of producers in New York as well as in Canada, and a higher percentage of day-neutral growers, compared to that of June-bearing producers, reported using protected culture. Botrytis (gray mold), weeds, and leaf spots were the top overall pest pressures indicated by growers. Survey respondents preferred written outreach materials and on-farm meetings to obtain information. Integrated pest management, organic production, and cultivar performance were the top priorities for subjects. The survey and interviews also provided information about the most common strategies for winter protection, frequency of pesticide applications, lifespan of plantings, and other current strawberry production practices in the region. Our survey results may be used by researchers and extension professionals to better serve this diversifying industry.
