Abstract The use of wood is often indicated as a decarbonization strategy for the construction sector. However, the CO 2 footprint of native wood, that is, the emissions during wood harvesting, transportation, and processing, depends on the type of forest management practiced. This study quantifies the CO 2 footprint of native rough sawn lumber from forests with three types of harvesting: sustainable management, conventional management, and conventional selective extraction (deforestation). CO 2 emissions were analyzed from harvesting to the end of wood processing based on data from the literature and the Construction Environmental Performance Information System. The CO 2 footprint of rough sawn lumber varies between 25 and 19,860 kCO 2 /m 3 , with the lowest values for wood from sustainable management and the highest for conventional selective extraction. In addition, managed wood stores temporarily in its cell structure ~353kgC/m 3 . Native wood from sustainable harvesting can contribute to decarbonizing buildings, whereas wood from conventional harvesting and deforestation are relevant sources of CO 2 emissions, considering the wood life cycle. sector However transportation practiced deforestation.

Resmo O uso da madeira é frequentemente apontado como uma estratégia de descarbonização para a construção. Entretanto, a pegada de CO2 da madeira nativa, ou seja, que são as emissões decorrentes da sua exploração florestal, transporte e beneficiamento, depende do tipo de manejo florestal. Este estudo quantifica a pegada de CO2 da madeira nativa serrada bruta, proveniente de três tipos de exploração florestal: manejo sustentável, manejo convencional e extração seletiva convencional (desmatamento). Analisaram-se as emissões de CO2 da exploração florestal até o término do beneficiamento da madeira, com dados da literatura e do Sistema de Informação do Desempenho Ambiental da Construção. A pegada de CO2 da madeira serrada bruta varia entre 25 e 19.860 kgCO2/m3, com os menores valores para a madeira de manejo sustentável e os maiores para a madeira de extração seletiva convencional. Além disso, a madeira manejada estoca temporariamente, em sua estrutura celular, ~353 kgC/m3.

ABSTRACT One of the most important aspects for sustainable aquaculture is the proper management of feed, for which the best strategy is the implementation of automatic feeders that allow optimizing feed rations and optimizing productive performance. The present study evaluated the impact of automatic feeding on soil quality in the cultivation of Litopenaeus vannamei in three experimental pools in a period of three months; where were evaluated the amount of organic matter, organic carbon, pH, nitrogen and the carbon-nitrogen ratio (C/N) to evaluate if there are differences in the feeding and lung-type zones. In the final analyzes no statistical differences (p ≥ 0.05) were observed in the parameters between the feeding areas and between the pools. These results demonstrate that automatic feeding does not cause changes in soil quality in the cultivation of L. vannamei.

RESUMEN Uno de los aspectos más importantes para una acuacultura sustentable es el manejo adecuado del alimento, para lo cual la mejor estrategia es la implementación de alimentadores automáticos que permiten optimizar las raciones de alimento y optimizar el rendimiento productivo. El presente estudio evaluó el impacto de la alimentación automática sobre la calidad del suelo en el cultivo de Litopenaeus vannamei en tres piscinas experimentales en un periodo de tres meses; se evaluaron las cantidades de materia orgánica, carbono orgánico, pH, nitrógeno y la relación carbono-nitrógeno (C/N) para discernir si existen diferencias en los puntos de alimentación y de tipo pulmón. En los análisis finales no se observaron diferencias estadísticas (p ≥ 0.05) entre los puntosde alimentación y entre las piscinas. Estos resultados demuestran que la alimentación automática no provoca cambios en la calidad del suelo en el cultivo de L. vannamei.

Research that directs the way stakeholders act and how they collaborate is essential when addressing complex environmental challenges in the field of sustainability science. For example, researchers attempting to manage Prosopis invasions through biological control in South Africa have historically faced challenges from stakeholders. In this study we illustrate the importance of stakeholder engagement and social learning by outlining the collaborative efforts of various stakeholders to promote effective, integrative and sustainable management of Prosopis invasions in the Northern Cape, South Africa. Through a community of practice approach, stakeholders worked together over the past half-decade in an attempt to develop a National Strategy for Prosopis management and improve its control. This strategy aimed not only to emphasise the need for integration of biomass use (aimed at offsetting the costs of mechanical clearing and necessary herbicide use) but also to underscore the significance of biocontrol alongside other management approaches. Stakeholders also identified that adequate farm-scale planning is necessary to provide a sense of purpose and assist in monitoring of progress. We worked alongside land managers and experts to develop such plans. The engagement of local champions played a crucial role in facilitating collaboration and learning among stakeholders, emphasising the significance of inclusive approaches in addressing complex sustainability challenges. In addition, we gained an understanding of how to develop the community of practice to enhance collaboration that ensures the implementation of plans to better manage Prosopis. Our findings underscore the necessity of meaningful stakeholder engagement and collaboration in effective invasive species management. By promoting understanding and involvement of diverse stakeholders, initiatives can have a greater impact in addressing broader sustainability issues. SIGNIFICANCE: Our findings highlight the fundamental role of stakeholder collaboration in addressing environmental challenges (e.g. biological invasions), promoting sustainability and fostering social learning. Collaboration facilitates exchange of knowledge, promotes social learning and allows stakeholders to make informed decisions when addressing sustainability issues. Collaborative approaches promote the effectiveness of a community of practice in managing Prosopis invasions in South Africa. Local champions played a pivotal role in facilitating collaboration, bridging communication gaps and promoting inclusive approaches. Sustained stakeholder engagement, transdisciplinary collaborations, effective biological control and market development for biomass products will be essential to improve the sustainable management Prosopis.

RESUMO Os sistemas de produção integrados surgiram como uma estratégia de produção sustentável na intensificação do uso da terra com impacto mínimo nas funções do ecossistema. Este estudo utilizou ferramentas de agricultura de precisão para investigar a variabilidade espacial de propriedades do solo e da vegetação em área de Integração Lavoura-Pecuária-Floresta (ILPF) e área de Integração Pecuária-Floresta (IPF) em São Carlos, SP, Brasil. Consequentemente, foram avaliados: (1) as propriedades físico-químicas do solo, (2) a resistividade elétrica, e (3) os atributos da cultura do Eucalyptus urograndis que compõem a área de estudo. As amostragens foram realizadas em (1) agosto de 2021 nas profundidades de 0-0,2 e 0,2-0,4 m; (2) outubro de 2021 nas profundidades de 0-0,5, 0-1,0 e 0-2,0 m; e (3) abril de 2021 e abril de 2022. Os resultados indicaram que os valores dos parâmetros de fertilidade do solo foram adequados ao desenvolvimento da cultura e apresentaram baixa variabilidade espacial. As análises de solo indicaram baixa acidez, altos teores de matéria orgânica, teores médios de fósforo, potássio e capacidade de troca catiônica e altos teores de cálcio, magnésio e saturação por base. Entretanto, foram observados locais com maior variabilidade espacial para cálcio, refletindo variabilidade na capacidade de troca catiônica e saturação por base. A granulometria e a resistividade elétrica do solo apresentaram baixa variabilidade espacial na camada superficial.

ABSTRACT Integrated production systems have emerged as a sustainable production strategy in intensifying land use with minimal impact on ecosystem functions. This study used precision agriculture tools to investigate the spatial variability of soil and vegetation properties in an integrated crop-livestock-forestry (ICLF) and in an integrated livestock-forestry (ILF) area of São Carlos city, SP, Brazil. Consequently, the following were assessed: (1) the soil physicochemical properties, (2) the electrical resistivity, and (3) the attributes of the Eucalyptus urograndis crop comprising the study area. Samplings were performed in (1) August 2021 at depths of 0-0.2 and 0.2-0.4 m; (2) October 2021 at depths of 0-0.5, 0-1.0, and 0-2.0 m; and (3) April 2021 and April 2022. Results indicated that the values for soil fertility parameters were suitable for crop development and presented low spatial variability. Soil analyses indicated low acidity, high levels of organic matter, average cation exchange capacity, phosphorus and potassium contents, high base saturation, and calcium and magnesium levels. However, locations with greater spatial variability for calcium were observed, reflecting cation exchange capacity and base saturation variability. Soil granulometry and electrical resistivity had a low spatial variability at the surface layer. Even without differences in the soil properties, there was a difference of 15% in the larger wood volume in the ILF then ICLF system. functions croplivestockforestry livestock forestry (ICLF livestockforestry (ILF city SP Brazil Consequently assessed 1 (1 2 (2 3 (3 202 00.2 002 0 0.2 0-0. 0.20.4 0204 0.4 4 0.2-0. m 00.5, 005 0.5, 5 0-0.5 01.0, 010 1.0, 0-1.0 02.0 020 2.0 0-2. 2022 acidity matter contents However observed layer 15 system ( 20 00 00. 02 0. 0-0 0.20. 04 0.2-0 00.5 05 0.5 01 01.0 10 1.0 0-1. 02. 2. 0-2 0- 0.20 0.2- 01. 1. 0-1

ABSTRACT Finding sustainable methods for utilizing biosolids, also known as municipal sewage sludge (SS), presents a pressing challenge in modern waste management practices. Therefore, this study aimed to evaluate the impact of SS amendment on growth, biochemical, proximate, and heavy metal bioaccumulation parameters of berseem clover (Trifolium alexandrinum L.) fodder crop under field conditions. Trifolium alexandrinum was cultivated using different rates of SS mixing (i.e., T0: 0% as control with no SS application, T1: 5%, and T2: 10%). The results obtained showed a significant (p < 0.05) increment in growth, biochemical, and proximate parameters of T. alexandrinum with an increasing SS mixing rate. The highest productivity of T. alexandrinum fodder (1.92 kg m-2 fw) was observed in the T2 treatment as compared to the control treatment. The heavy metal analysis of shoot and root parts of T. alexandrinum showed that the contents (mg kg-1) of eight elements (Cd 0.02-0.13, Co 0.04-0.08, Cu 5.94-0.05, Cr 0.43-1.68, Fe 7.08-15.93, Ni 0.89-2.90, Mn 1.62-5.38, and Zn 3.30-7.04) increased significantly (p < 0.05) with SS mixing rate. The bioaccumulation factor (BAF) was below 1 except for Cu and Zn exhibiting their rapid uptake by plants from SS-treated soils. However, dietary intake modeling (DIM < 1) and health risk index (HRI < 1) studies showed that the levels of heavy metals did not exceed the permissible limits in any SS treatment. Overall, SS amendment has a positive impact on the growth, biochemical, proximate, and heavy metal characteristics of T. alexandrinum. Therefore, this study suggested a strategy for low-cost soil fertilization and fodder crop production which could sustainably benefit waste recycling.

ABSTRACT Overfishing, industrial fishing and climate change generate impacts that affect the marine fishery resource, the main source of income and food for coastal populations of artisanal fishers. The creation of conditions that increase the adaptive capacity of fishers will decrease their vulnerability to impacts. This research proposes to determine an Exclusive Zone for Artisanal Fishing-ZEPA as a strategy for sustainable management of fishery resources and climate adaptation for artisanal fishers in the study area. Marxan was used to identify three scenarios for the location of the ZEPA and participatory mapping was carried out with fishers to obtain the fourth scenario. High similarity was found between scenarios 2 and 4, which shows that the scientific (Marxan) and participatory (population) approaches coincide in the location of the ZEPA. The final ZEPA was located in the coastal marine zone of the municipalities of Tumaco and Francisco Pizarro, with a total area of 2,008 km2. Included important conservation targets for artisanal fisheries such as artisanal fishing grounds, ecosystems (mangroves, beaches and estuaries), areas of occurrence of species (seerfish, snappers, sea bass, piangua, marmoset shrimp) among others. More than 80 % of the fishers agreed that the strategy would help reduce their vulnerability to threats such as climatic phenomena, overfishing, pollution, among others. The contribution to climate change adaptation of the study area’s population is highlighted.

RESUMEN La sobrepesca, la pesca industrial y el cambio climático generan impactos que afectan al recurso pesquero marino, la principal fuente de ingreso y alimento de las poblaciones costeras de pescadores artesanales. La creación de condiciones que incrementen la capacidad de adaptación de los pescadores disminuirá su vulnerabilidad a los impactos. Esta investigación propone determinar una Zona Exclusiva de Pesca Artesanal-ZEPA como estrategia de manejo sostenible de los recursos pesqueros y de adaptación climática para los pescadores artesanales del área de estudio. Se utilizó el programa Marxan para identificar tres escenarios para la ubicación de la ZEPA y se realizó una cartografía participativa con pescadores para obtener el cuarto escenario. Se encontró similitud alta entre el escenario 2 y 4, lo que muestra que el enfoque científico (Marxan) y participativo (población) coinciden en la ubicación de ZEPA. La ZEPA definitiva se ubicó en la zona marino costera de los municipios de Tumaco y Francisco Pizarro, con un área total de 2 008 km2. Incluyó objetos de conservación importantes para la pesca artesanal como caladeros de pesca artesanal, ecosistemas (manglares, playas y estuarios), áreas de ocurrencia de especies (sierra, pargos, corvina, piangua, camarón tití), entre otros. Se identificó que más de 80 % de los pescadores estuvo de acuerdo en que la estrategia le aportaría a reducir su vulnerabilidad frente a amenazas como fenómenos climáticos, sobrepesca, contaminación, entre otros. Se resalta la contribución a la adaptación al cambio climático de la población del área de estudio.

Abstract The National Institute of Biodiversity of Costa Rica (INBio), the first institution of its kind worldwide, was created in 1989 as a civil society organization, with the mission of promoting greater awareness of the value of biodiversity, to achieve its conservation and promote human development. It operated within the framework of a national biodiversity conservation strategy consisting of three types of actions: “save, know and use”, forming a publicprivate alliance with the National System of Conservation Areas, whose work represented the first step of “saving”. INBio focused on the generation of scientific knowledge of Costa Rican biodiversity (knowing) and the search and promotion of its intelligent use (using). This article describes the genesis of the institution and its main contributions to the knowledge and use of Costa Rican biodiversity between 1989-2015. These include the results of the protected areas biodiversity inventory process and the development of the largest systematic collection of biological specimens in the country’s history, fully systematized; the development of an information management system that integrated all the information from the inventory and the specimens in its collection in digital format, allowing global access to this information or its correlation with that of other sources. The results of promoting and facilitating the use of information through five programs: Natural Sciences and Conservation Biology, for scientific purposes; Bioliteracy and Education, conceptually designed for the teaching and development of awareness about the value of biodiversity; Bioprospecting, the systematic search for economic uses of biodiversity for medicinal, agricultural and industrial purposes; Conservation for Development, the use of the information for wild areas conservation purposes, surrounding communities or nature tourism, among others; Technical Assistance and Training, program in charge of assisting public and private entities, inside and outside the country, in the development of initiatives in which Biodiversity was the central element. The main results of its work and the national and international awards that INBio received for its innovative approaches and contributions are described, as well as the financial and political reasons why INBio discontinued its activities in the period 2015-2016 are summarized. Viewing the work of INBio as a first stage, the importance and need to continue with a state program on the knowledge and use of Costa Rican biodiversity is raised, in addition to its protection, with the goal of creating awareness of its value before the serious threats to life on Earth.

Resumen El Instituto Nacional de Biodiversidad de Costa Rica (INBio), la primera institución en su género en el mundo, fue creado en 1989 como una organización de la sociedad civil, con la misión expresa de promover una mayor conciencia del valor de la biodiversidad, para lograr su conservación y fomentar el desarrollo humano. En el marco de una estrategia nacional de conservación de la biodiversidad consistente en tres tipos de acciones: “salvar, conocer y utilizar”, se conformó una alianza público-privada con el Sistema Nacional de Áreas de Conservación, cuya labor representó el primer paso de “salvar”. El INBio se centró en la generación de conocimiento científico de la biodiversidad costarricense (el “conocer”) y en la búsqueda y promoción de su uso inteligente (el “usar”). Este artículo describe la génesis de la institución y sus principales aportes al conocimiento y la utilización de la biodiversidad costarricense en el período 1989-2015. Estos incluyen los resultados del proceso de inventario de la biodiversidad de las áreas protegidas y el desarrollo de la colección sistemática de especímenes biológicos más grande en la historia del país, totalmente sistematizada; el desarrollo de un sistema de manejo de información que integró en formato digital toda la información del inventario y de los especímenes de su colección, permitiendo el acceso global a estos datos o su correlación con la de otras fuentes. Los resultados de la promoción y la facilitación del uso de la información se lograron mediante cinco programas: Ciencias Naturales y Biología de la Conservación, con fines científicos; Bioalfabetización y Educación, conceptualmente diseñados para la enseñanza y el desarrollo de la conciencia del valor de la biodiversidad; Bioprospección, la búsqueda sistemática de usos económicos de la biodiversidad para fines medicinales, agrícolas e industriales; Conservación para el Desarrollo, el empleo de la información para la conservación de áreas silvestres, comunidades circunvecinas o turismo naturalista, entre otros; y Asistencia Técnica y Capacitación, programa encargado de asistir a entidades públicas y privadas, dentro y fuera del país, en el desarrollo de iniciativas en que la biodiversidad fuera el elemento central. Se describen los principales resultados de su labor y los reconocimientos nacionales e internacionales que el INBio recibió por sus novedosos enfoques y aportes, al igual que se resumen las razones de carácter financiero y político por las cuales el INBio descontinuó sus actividades en el período 2015-2016. Vista la labor del INBio como una primera etapa, se plantea la importancia y necesidad de continuar con un programa estatal sobre el conocimiento y uso de la biodiversidad costarricense, en adición a su protección, con el fin último de que exista conciencia de su valor ante las serias amenazas para la vida en el planeta.

Abstract Community management of cultural heritage includes various actors and disciplines with the objective of guaranteeing the sustainable conservation of this heritage through research, documentation, and the development of communication strategies. Here, we analyze the actions taken between the years 2022 - 2023 with the Amaná community (La Rioja province) as it relates to the valorization of their natural and cultural heritage. At the beginning, we faced several challenges to understand the needs of the local community, also we develop a strategy to valorize and provide training about heritage public use. Our methodology comprehend a spiraling model for communication that is significant, participative and includes multiple voices. This model has steps that work together from the beginning of the process in a broad and multilineal way. The key points of the communication were focused at what we want to show, why and how, and what we hope to achieve. To reach this goal we took the following actions: we designed different trails throughout the town, organized activities of heritage education at the school, and, at the same time, recorded the local traditions.

Abstract The aim of this study was to examine the impact of both organic and inorganic nitrogen fertilizers on the intensity and epidemiological components of Cercospora leaf spot across three different canopies of cotton plants, specifically the variety DP ACALA 90, under field conditions. Fertilizers used in the study included bovine manure, Jatropha curcas seedcake, poultry manure, and urea (the latter serving as a control). These were applied at 20 days after plant emergence and then during the flowering stage until the total nitrogen (N) dose reached 50, 100, 150, or 200 kg N per hectare. The incidence and severity of the disease were assessed starting at the reproductive stage B1 (the first visible flower bud) across the lower, middle, and upper canopies of four cotton plants, with six evaluations conducted over time. To calculate the initial inoculum (Y 0 ) and the disease progress rate (r), the Exponential, Gompertz, and Logistic models were employed based on temporal data. The study was designed as a randomized complete block with a 4x4 factorial arrangement (fertilizer type x dose), and mean comparisons were made using Tukey's test (p ≤ 0.05). It was found that disease intensity within each canopy level varied in response to the type of nitrogen source and the applied dose, with the severity of the disease (including the area under the disease progress curve) being particularly influenced. A significant interaction between the type of fertilizer and the dose regarding the intensity of Cercospora leaf spot was observed. The Exponential model most accurately depicted the disease's temporal progression. Notably, poultry manure and urea were the fertilizers that most adversely influenced the intensity and initial inoculum (Y 0 ) of Cercospora leaf spot across the various canopies of the cotton plants. The findings suggest that the use of organic fertilizers in cotton cultivation could represent a viable sustainable management strategy.

Abstract The State has significant purchasing power. Public procurement is a great potential to promote and apply public policies that have social, environmental, labor and economic objectives. The sustainability referred to these contracts constitutes a government management strategy that is framed in constitutional principles, insofar as it constitutes an effective tool in the satisfaction of social needs. Therefore, sustainable public procurement should be aimed at acquiring goods of sustainable design, innovative, that are friendly to the environment and that conform to criteria of inclusion, equality and social equity.

Resumen El Estado tiene un importante poder de compra. Las contrataciones públicas son un gran potencial para promover y aplicar políticas públicas con objetivos sociales, ambientales, laborales y económicos. La sustentabilidad referida a esos contratos constituye una estrategia de gestión gubernamental que se enmarca en los principios constitucionales, en la medida que aquel constituye una herramienta efectiva para la satisfacción de las necesidades sociales. Por lo tanto, las contrataciones públicas sustentables deber estar dirigidas a adquirir bienes de diseño sustentable, innovadores, que sean amigables con el medio ambiente y que se ajusten a criterios de inclusión, de igualdad y de equidad social.

Abstract Weeds negatively affect the sustainability of farming systems in the European Union (EU), the management of which relies heavily on herbicides. The EU's farm-to-fork strategy aims to promote agroecology and the transition to sustainable and resilient farming systems, including the reduction of herbicide use. GOOD is a 4-year project that takes a multidisciplinary approach and aims to create and evaluate agroecological weed management (AWM) systems, and demonstrate that the adoption of such a system will improve the sustainability and resilience of farming systems across Europe and beyond. This objective will be achieved through the development, evaluation and demonstration of innovative combinations of AWM using cover crops, beneficial microorganisms and digital tools. This will be carried out in living-labs, co-created with stakeholders in 6 different EU pedoclimatic regions, including annual and perennial crops and conventional, organic and mixed cropping systems. The combination of innovative and socio-economically validated sustainable agroecological practices will generate social, economic and environmental benefits through the reduction or elimination of chemical inputs and optimized use of natural resources GOOD will create an Agroecological Weed Management Network (AWMN), inviting agroecology practitioners from all continents to dialogue and exchange knowledge and best practices towards diversified agroecology-based farming systems.

Resumen Las hierbas adventicias afectan negativamente a la sostenibilidad de los sistemas agrícolas de la Unión Europea (UE), cuya gestión depende en gran medida de los herbicidas. La estrategia "de la granja a la mesa" de la UE tiene como objetivo promover la agroecología y la transición hacia sistemas agrícolas sostenibles y resilientes, incluyendo la reducción del uso de herbicidas. GOOD es un proyecto de 4 años de duración que adopta un enfoque multidisciplinar y aspira a crear y evaluar sistemas de gestión agroecológica de las malas hierbas (AWM, por sus siglas en inglés), y demostrar que la adopción de dicho sistema mejorará la sostenibilidad y la resiliencia de los sistemas de cultivo en toda Europa y fuera de ella. Este objetivo se logrará mediante el desarrollo, la evaluación y la demostración de combinaciones innovadoras de AWM utilizando cubiertas vegetales, microorganismos beneficiosos y herramientas digitales. Esto se llevará a cabo en living-labs, co-creados con las partes interesadas en 6 diferentes regiones pedoclimáticas de la UE, incluyendo cultivos anuales y perennes y sistemas de cultivo convencionales, ecológicos y mixtos. La combinación de prácticas agroecológicas sostenibles innovadoras y validadas socioeconómicamente generará beneficios sociales, económicos y medioambientales mediante la reducción o eliminación de insumos químicos y el uso optimizado de los recursos naturales. GOOD creará una Red de Gestión Agroecológica de las Malas Hierbas (AWMN), invitando a profesionales de la agroecología de todos los continentes al diálogo y al intercambio de conocimientos y mejores prácticas hacia sistemas agrícolas diversificados basados en la agroecología.

ABSTRACT The symbiosis of common beans with nitrogen-fixing bacteria provides an efficient approach to sustainable and economical food production. Therefore, this study aimed to evaluate the application of cost-effective nitrogen management strategies in organic common bean cultivation, including the application of poultry manure and organic liquid fertilizer, seed and co-inoculation with diazotrophic bacteria (Azospirillum brasilense and/or Rhizobium tropici), and supplementary Rhizobium tropici inoculation. The study spanned three years in a well-established organic cultivation field (2018) and an initial organic cultivation area (2019 and 2020) in Brazil. It was arranged in a randomized blocks design in a 2 × 5 (2018) and 2 × 6 (2019 and 2020) factorial scheme, with four replicates. The most profitable strategy involves seed inoculation with Azospirillum brasilense and additional inoculation with Rhizobium tropici at stage V4-5 (fifth trifoliate leaf fully expanded), while the most costly strategy was the application of poultry manure at the V3 stage (first trifoliate leaf fully expanded). Thus, the use of diazotrophic bacteria for seed inoculation and co-inoculation (Azospirillum brasilense and/or Rhizobium tropici) ensured financial returns and system profitability in common bean cultivation. nitrogenfixing fixing production Therefore costeffective cost effective fertilizer coinoculation co andor or tropici, , wellestablished well established 2018 (2018 2019 (201 2020 Brazil scheme replicates V45 V V4 V4- fifth expanded, expanded expanded) first expanded. .

RESUMO A simbiose do feijão comum com bactérias fixadoras de nitrogênio proporciona uma abordagem eficiente para a produção de alimentos sustentável e econômica. Portanto, este estudo teve como objetivo avaliar a aplicação de estratégias custo-efetivas de manejo de nitrogênio no cultivo orgânico do feijão comum, incluindo a aplicação de esterco de aves e fertilizante orgânico líquido, inoculação de sementes e coinoculação com bactérias diazotróficas (Azospirillum brasilense e/ou Rhizobium tropici), e inoculação suplementar com Rhizobium tropici. O estudo durou três anos em um campo de cultivo orgânico bem estabelecido (2018) e uma área inicial de cultivo orgânico (2019 e 2020) no Brasil. O delineamento foi em blocos casualizados em esquema fatorial 2 × 5 (2018) e 2 × 6 (2019 e 2020), com quatro repetições. A estratégia mais lucrativa envolve a inoculação de sementes com Azospirillum brasilense e inoculação adicional com Rhizobium tropici no estádio V4-5 (quinta folha trifoliada totalmente expandida), enquanto a estratégia mais cara foi a aplicação de esterco de aves no estádio V3 (primeira folha trifoliada totalmente expandida). Assim, o uso de bactérias diazotróficas para inoculação e coinoculação de sementes (Azospirillum brasilense e/ou Rhizobium tropici) garantiu retorno financeiro e rentabilidade do sistema no cultivo do feijão comum. econômica Portanto custoefetivas custo efetivas líquido eou ou tropici, , 2018 (2018 2019 (201 2020 Brasil 2020, repetições V45 V V4 V4- quinta expandida, expandida expandida) primeira expandida. .
