Abstract Introduction: while high-risk processes with high accident rates challenge safety, High Reliability Organization (HRO) achieve excellent indicators. In both cases, prevention seems to have reached a limit. In the former, because it seems powerless to generate prevention; in the latter, because it has been so successful that it seems impossible to reach greater levels. Objective: to highlight the contribution of Ergonomics to safety in these situations, pointing out unexplored possibilities such as design Ergonomics in man-machine integration (computerized systems). Method: comparative analysis of findings from ergonomic studies on production systems with high accident rates and HRO. Discussion: analysis of the motorcycle freight drivers’ activity revealed alternatives yet to be explored between unfavorable work relations and the perceived inevitability of accidents. The apparent limit of HRO can be overcome with recent advances in the analysis of situated action and cognition and by building debate spaces based on field experience. Collaborative design practices, which draw on worker experience to feed learning dynamics and technical reliability, remains a poorly explored possibility in Safety Engineering when it comes to computerized systems.

Resumo Introdução: processos de alto risco com elevadas taxas de acidentes desafiam a segurança. Por outro lado, sistemas ultrasseguros conquistaram ótimos indicadores. Em ambos, a prevenção parece ter chegado a um limite - em um deles, porque parece impotente para gerar prevenção; no outro, porque foi tão bem-sucedida que parece impossível avançar. Objetivo: evidenciar a contribuição da Ergonomia em prol da segurança, nas situações descritas, suas possibilidades ainda por explorar, entre elas a Ergonomia de concepção na integração homem-máquina (sistemas informatizados). Método: análise comparativa dos achados oriundos de estudos ergonômicos em sistemas de produção com altas taxas de acidentes e sistemas ultrasseguros. Discussão: a análise da atividade dos motofretistas mostrou que existem alternativas de ação ainda não exploradas entre as relações de trabalho desfavoráveis e a percepção de inevitabilidade dos acidentes. Nos sistemas ultrasseguros, o aparente limite pode ser superado com os avanços recentes na análise da ação e cognição situadas e na construção de espaços de debate que permitam o retorno da experiência de campo. Em sistemas informatizados, as práticas de projeto colaborativo, que se valem da experiência dos trabalhadores para alimentar as dinâmicas de aprendizagem e a confiabilidade técnica, são possibilidades ainda pouco praticadas na Engenharia de Segurança.

Abstract The use of computational simulation techniques is an important tool for the coffee harvesting issues, particularly the finite element method. The method is widely used in the structural analysis of agricultural machinery, as well as in the analysis of the stresses and vibrations of coffee branches and peduncles during the harvesting process. The present study aimed to develop three-dimensional finite element models of the plagiotropic branches of the Catuaí Vermelho variety of Arabica coffee in different positions along the orthotropic branches of the plant; considering high-fidelity models. Additionally, by considering the branches’ experimental properties (physical-mechanical), the natural frequencies and vibration modes of the branches were determined by means of computer simulations. First, the geometric properties of the coffee branches were obtained by means of two images taken using a professional camera to obtain the input data of the virtual simulation. For the mechanical properties, it was used a semi-analytical digital scale, to obtain the mass of the specimens. The modulus of elasticity was determined using a universal testing machine. The variability in the simulated natural frequencies could be identified, which was on the order of 30% for the first frequency, regardless of the position of the branch in the plant. These values were lower for the other frequencies. Linear regression fits showed a coefficient of determination, and correlation tests were used to verify the relationship between the values obtained numerically and experimentally, which were validated by using experimental data using the modal analysis techniques.

Resumo Um quisto púbico cartilaginoso é uma lesão degenerativa rara e benigna que tem origem na fibrocartilagem da sínfise púbica. Habitualmente, tende a ocorrer em mulheres pós-menopausa e deve ser considerado no diagnóstico diferencial de massas quísticas púbicas e vulvares. Tratando-se de uma lesão incomum, excecionalmente rara em homens, pode estar associada a erros diagnósticos, sendo a Ressonância Magnética (RM) a modalidade de imagem de eleição para a melhor caracterização. Apresentamos um caso de um quisto retropúbico detetado incidentalmente numa Ressonância Magnética da anca num homem de 57 anos.

Abstract A pubic cartilaginous cyst is a rare, benign, slow-growing degenerative lesion arising from the fibrocartilaginous part of the pubic symphysis joint usually occurring in post-menopausal women. It should be considered in the differential diagnosis of pubic and vulvar cystic masses. Since it is an uncommon lesion, especially in men, it can be easily misdiagnosed. Magnetic Resonance imaging is the investigation of choice for this condition. We report a case of a retropubic cyst incidentally detected in a 57-year-old male patient who performed a hip Magnetic Resonance imaging.

Resumo Este estudo objetivou analisar a demanda da cirurgia pediátrica e fatores associados à inadequação da idade cirúrgica. Trata-se de estudo transversal, com aplicação de questionários, em cidade polo do norte de Minas Gerais, Brasil. A associação entre a inadequação da idade cirúrgica foi verificada para fatores demográficos, sociais e assistenciais por meio de análises bivariadas, seguidas de regressão de Poisson, com variância robusta, assumindo-se um nível de significância de 5%. Participaram 532 crianças, 79.3% do sexo masculino. O intervalo médio entre o encaminhamento inicial e a cirurgia foi de 9.2 meses. A frequência de idade inadequada para intervenção cirúrgica foi de 44.4%. As variáveis associadas com a inadequação foram sexo masculino (RP = 1.09; IC95% = 1.01-1.18), baixa escolaridade materna (RP = 1.13; IC95% = 1.06-1.20) e idade de percepção da afecção superior a 1 ano de idade (RP = 1.09; IC95% = 1.02-1.15). Há uma alta ocorrência na inadequação da idade para os procedimentos cirúrgico e entre os fatores associados destacam-se as condições sociais das famílias. Estratégias devem ser elaboradas para reduzir o tempo de espera para crianças com necessidade de intervenção cirúrgica.

Abstract This study aimed to analyze the demand for pediatric surgery and the factors associated with inadequate surgical age. This cross-sectional study was carried out using questionnaires in a northern Minas Gerais, Brazil hub city. The association between inadequate surgical age and demographic, social, and care factors was verified using bivariate analysis followed by Poisson regression with robust variance and a significance level of 5%. A total of 532 children participated 79.3% were male. The median interval between the first referral from primary health care until surgery was 9.2 months. The frequency of inadequate surgical age was 44.4%. Variables associated with inadequate age were: male (PR = 1.09; CI95% = 1.01-1.18), low maternal education (PR = 1.13; CI95% = 1.06-1.20), and age perception of affection higher one year (PR = 1.09; IC95% = 1.02-1.15). There is a high occurrence of inadequate age for surgical procedures, and among the factors that justify these findings are the social conditions of the families. Strategies must be developed to reduce the waiting time between the specialist’s evaluation and definitive treatment.

Resumen Con el aumento exponencial de la cantidad de datos generados diariamente, se ha intensificado el interés de las organizaciones por desarrollar estrategias para el manejo de Big Data. Un ejemplo de Big Data brasileño es la Plataforma CNPq Lattes, que permite extraer información de los currículos de los investigadores registrados en ella. Una de las limitaciones de la plataforma es que la información se ordena individualmente para cada investigador y sin un estándar de indexación, lo que hace imposible extraer datos de los investigadores simultáneamente. Para remediar este problema, se desarrolló el software ScriptLattes, utilizado en el presente estudio, para extraer información de los currículos de investigadores en oncología inyectable, con el fin de obtener una visión panorámica de sus producciones técnico-científicas. En cuanto a las actividades realizadas por estos especialistas en el período analizado, se observaron un total de: 85.465 artículos completos publicados, 24.068 producciones técnicas y 13.496 proyectos implementados. Los análisis de red realizados con la ayuda del software Gephi señalaron al Dr. Fernando de Queiroz Cunha, de la Facultad de Medicina de Ribeirão Preto (USP), como el investigador más destacado del área. A pesar de las limitaciones de la Plataforma Lattes, los resultados demostraron ser eficientes, posibilitando la generación de conocimiento científico y tecnológico en oncología inyectable en varios niveles institucionales.

Abstract With the exponential increase in the amount of data generated daily, the interest of organizations in developing strategies for handling Big Data has intensified. An example of Brazilian Big Data is the CNPq Lattes Platform, which allows extracting information from the curricula of researchers registered therein. One of the limitations on the platform is that the information is arranged individually for each researcher and without an indexing standard, making it impossible to extract data from researchers simultaneously. To remedy this problem, the ScriptLattes software was developed, used in the present study, to extract information from the curricula of researchers in injectable oncology, to obtain a panoramic view of their technical and scientific productions. Regarding the activities carried out by these specialists in the analyzed period, a total of: 85,465 published complete articles, 24,068 technical productions and 13,496 implemented projects were observed. Networking analyzes performed applying Gephi software pointed Dr. Fernando de Queiroz Cunha, from the Faculty of Medicine of Ribeirão Preto (USP), as the most prominent researcher in the area. Despite the limitations of the Lattes Platform, the results proved to be efficient, enabling the generation of scientific and technological knowledge in injectable oncology at various institutional levels.

Resumo Com o aumento exponencial na quantidade de dados gerados diariamente, têm-se intensificado o interesse das organizações em desenvolver estratégias para o tratamento do Big Data. Um exemplo de Big Data brasileiro é a Plataforma Lattes do CNPq, que permite extrair informações dos currículos dos pesquisadores nela cadastrados. Uma das limitações na plataforma é que as informações são dispostas individualmente para cada pesquisador e sem um padrão de indexação, impossibilitando a extração dos dados dos pesquisadores simultaneamente. Para sanar tal problema, foi desenvolvido o software ScriptLattes, utilizado no presente estudo, para extrair as informações dos currículos dos pesquisadores em oncológicos injetáveis, visando obter uma visão panorâmica das produções técnicas e científicas destes.

Abstract Background Ischemic stroke is an important cause of death in the world. The malignant middle cerebral artery infarction (MMCAI) has mortality as high as 80% when clinically treated. In this setting, decompressive craniectomy is a life-saving measure, in spite of high morbidity among survivors. Objective To evaluate the outcomes of patients with MMCAI treated with decompressive craniectomy in a Brazilian academic tertiary stroke center. Methods A prospective stroke database was retrospectively evaluated, and all patients treated with decompressive craniectomy for MMCAI between January 2014 and December 2017 were included. The demographics and clinical characteristics were evaluated. The functional outcome, measured by the modified Rankin Scale (mRS), was assessed at hospital discharge, after 3-months and 1-year of follow-up. Results We included 53 patients on the final analysis. The mean age was 54.6 ± 11.6 years and 64.2% were males. The median time from symptoms to admission was 4.8 (3–9.7) hours and the mean time from symptoms to surgery was 36 ± 17 hours. The left hemisphere was the affected in 39.6%. The median NIHSS at admission was 20 (16–24). The in-hospital mortality was 30.2%. After a median of 337 [157–393] days, 47.1% of patients had achieved favorable outcome (mRS ≤ 4) and 39.6% had died. Conclusion Decompressive craniectomy is a life-saving measure in the setting of MMCAI, and its effects remains important in the scenario of a middle-income country in real-world situations.

Resumo Antecedentes O acidente vascular cerebral (AVC) isquêmico é uma causa importante da morte em todo o mundo. O infarto maligno da artéria cerebral média (IMACM) tem mortalidade de até 80% quando tratado clinicamente. Nesse contexto, a craniectomia descompressiva é uma medida salvadora de vidas, apesar da alta morbidade entre os sobreviventes. Objetivo Avaliar os desfechos dos pacientes com IMACM tratados com craniectomia descompressiva em um centro acadêmico terciário de AVC no Brasil. Métodos Um banco de dados prospectivo de AVC foi avaliado retrospectivamente e todos os pacientes tratados com craniectomia descompressiva para IMACM entre janeiro de 2014 e dezembro de 2017 foram incluídos. As características clínicas e demográficas foram avaliadas. Os desfechos funcionais, medidos pela escala modificada da Rankin (mRS), foram avaliados na alta hospitalar, após 3 meses e após 1 ano de seguimento. Resultados Foram incluídos 53 pacientes na análise final. A idade média foi 54,6 ± 11,6 anos e 64,2% eram homens. A mediana do tempo dos sintomas à admissão foi 4,8 (3–9,7) horas e o tempo médio dos sintomas à cirurgia foi 36 ± 17 horas. O hemisfério esquerdo foi o afetado em 39,6%. A pontuação na escala de AVC do National Institute of Health (NIHSS) à admissão foi 20 (16–24). A mortalidade hospitalar foi 30,2%. Após uma mediana de 337 (157–393) dias, 47,1% dos pacientes tinham atingido um desfecho favorável (mRS ≤ 4) e 39,6% tinham morrido. Conclusão Craniectomia descompressiva é uma medida salvadora de vidas no contexto do IMACM e seus efeitos permanecem importantes no cenário de um país em desenvolvimento em situação de vida real.

RESUMO OBJETIVO Estimar a soroprevalência de anticorpos do vírus SARS-CoV-2 em escolares de quatro a 14 anos de idade residentes no município de São Paulo, segundo variáveis clínicas, demográficas, epidemiológicas e sociais, durante o período de fechamento das escolas como medida de controle da covid-19. MÉTODOS Realizou-se um inquérito sorológico em setembro de 2020 com amostra aleatória estratificada por tipo de rede de ensino (pública municipal, pública estadual e privada). Foi coletada amostra de sangue venoso utilizando-se o teste de imunoensaio de fluxo lateral da fabricante Wondfo para detecção de anticorpos totais contra o vírus SARS-CoV-2. Aplicaram-se questionários semiestruturados para o levantamento de dados clínicos, demográficos, sociais e epidemiológicos. RESULTADOS A soroprevalência de anticorpos do vírus SARS-CoV-2 em escolares foi de 16,6% (IC95% 15,4–17,8). O estudo encontrou soroprevalências mais elevadas na rede pública municipal (18,5%; IC95% 16,6–20,6) e estadual (16,2%; IC95% 14,4–18,2) em relação à rede privada (11,7; IC95% 10,0–13,7) e entre escolares da raça/cor preta e parda (18,4%; IC95% 16,8–20,2) e no estrato social mais vulnerável (18,5%; IC95% 16,9–20,2). A pesquisa identificou menores soroprevalências nos escolares que relataram seguir as medidas recomendadas de proteção contra a covid-19. CONCLUSÃO A soroprevalência de anticorpos contra o vírus SARS-CoV-2 atinge principalmente os escolares socialmente mais vulneráveis. Este estudo pode contribuir para embasar políticas públicas que reforcem a importância da suspensão das aulas presenciais e da necessidade de estratégias de medidas de proteção e acompanhamento do status sorológico daqueles que ainda não foram contemplados no calendário vacinal.

ABSTRACT OBJECTIVE To estimate seroprevalence of SARS-CoV-2 antibodies in schoolchildren aged 4 to 14 years living in the city of São Paulo, according to clinical, demographic, epidemiological, and social variables, during the school closure period as a measure against covid-19 spread. METHODS A serological survey was made in September 2020 with a random sample stratified by school system (municipal public, state public and private) type. A venous blood sample was collected using the Wondfo SARS-CoV-2 Antibody Test (lateral flow method) for detection of total SARS-CoV-2 virus antibodies. Semi-structured questionnaires were applied to collect clinical, demographic, social, and epidemiological data. RESULTS Seroprevalence of SARS-CoV-2 antibodies in schoolchildren was of 16.6% (95%CI 15.4–17.8). The study found higher seroprevalence in the municipal (18.5%; 95%CI 16.6–20.6) and state (16.2%; 95%CI 14.4–18.2) public school systems compared to the private school system (11.7; 95%CI 10.0–13.7), among black and brown students (18.4%; 95%CI 16.8–20.2) and in the most vulnerable social stratum (18.5 %;95%CI 16.9–20.2). Lower seroprevalence was identified in schoolchildren who reported following the recommended protective measures against covid-19. CONCLUSION Seroprevalence of SARS-CoV-2 antibodies is found mainly in the most socially vulnerable schoolchildren. This study can contribute to support public policies that reinforce the importance of suspending face-to-face classes and developing strategies aimed at protective measures and monitoring of the serological status of those who have not yet been included in the vaccination schedule.

ABSTRACT OBJECTIVE To investigate the relationship between covid-19 hospital mortality and risk factors, innovating by considering contextual and individual factors and spatial dependency and using data from the city of São Paulo, Brazil. METHODS The study was performed with a spatial hierarchical retrospective cohort design using secondary data (individuals and contextual data) from hospitalized patients and their geographic unit residences. The study period corresponded to the first year of the pandemic, from February 25, 2020 to February 24, 2021. Mortality was modeled with the Bayesian context, Bernoulli probability distribution, and the integrated nested Laplace approximations. The demographic, distal, medial, and proximal covariates were considered. RESULTS We found that per capita income, a contextual covariate, was a protective factor (odds ratio: 0.76 [95% credible interval: 0.74–0.78]). After adjusting for income, the other adjustments revealed no differences in spatial dependence. Without income inequality in São Paulo, the spatial risk of death would be close to one in the city. Other factors associated with high covid-19 hospital mortality were male sex, advanced age, comorbidities, ventilation, treatment in public healthcare settings, and experiencing the first covid-19 symptoms between January 24 and February 24, 2021. CONCLUSIONS Other than sex and age differences, geographic income inequality was the main factor responsible for the spatial differences in the risk of covid-19 hospital mortality. Investing in public policies to reduce socioeconomic inequities, infection prevention, and other intersectoral measures should focus on lower per capita income, to control covid-19 hospital mortality.

RESUMO Objetivo: Identificar a variabilidade espacial da mortalidade por câncer de mama e colo do útero e avaliar fatores associados à mortalidade por esses cânceres no município de São Paulo. Métodos: Entre 2009 e 2016 foram registrados, no Sistema de Informações sobre Mortalidade, 10.124 óbitos por câncer de mama e 2.116 óbitos por câncer do colo do útero em mulheres com 20 anos e mais. Os registros foram geocodificados por endereço de residência e agregados segundo território adstrito. Foram realizadas modelagens de regressão espacial utilizando-se a abordagem bayesiana com estrutura de Besag-York-Mollié para verificar a associação dos óbitos com indicadores selecionados. Resultados: As taxas de mortalidade por esses cânceres apresentaram padrões espaciais inversos. As variáveis associadas à mortalidade por câncer de mama foram: tempo de deslocamento para o trabalho entre uma e duas horas (risco relativo — RR 0,97; intervalo de credibilidade — IC95% 0,93–1,00); mulheres responsáveis pelo domicílio (RR 0,97; IC95% 0,94–0,99) e óbitos por câncer de mama ocorridos em estabelecimentos privados (RR 1,04; IC95% 1,00–1,07). À mortalidade por câncer do colo do útero, estiveram associados: tempo de deslocamento para o trabalho entre meia e uma hora (RR 0,92; IC95% 0,87–0,98); rendimento domiciliar até três salários-mínimos (RR 1,27; IC95% 1,18–1,37); e razão de menores de um ano em relação à população feminina de 15 a 49 anos (RR 1,09; IC95% 1,01–1,18). Conclusão: Foram calculados os RR preditos para a mortalidade por esses cânceres, que estiveram associados às condições socioeconômicas das áreas de abrangência.

ABSTRACT Objective: To identify spatial variability of mortality from breast and cervical cancer and to assess factors associated in the city of São Paulo. Methods: Between 2009 and 2016, 10,124 deaths from breast cancer and 2,116 deaths from cervical cancer were recorded in the Mortality Information System among women aged 20 years and over. The records were geocoded by address of residence and grouped according to Primary Health Care coverage areas. A spatial regression modeling was put together using the Bayesian approach with a Besag-York-Mollié structure to verify the association of deaths with selected indicators. Results: Mortality rates from these types of cancer showed inverse spatial patterns. These variables were associated with breast cancer mortality: travel time between one and two hours to work (RR – relative risk: 0.97; 95%CI – credible interval: 0.93–1.00); women being the head of the household (RR 0.97; 95%CI 0.94–0.99) and deaths from breast cancer in private health institutions (RR 1.04; 95%CI 1.00–1.07). The following variables were associated with mortality from cervical cancer: travel time to work between half an hour and one hour (RR 0.92; 95%CI 0.87–0.98); per capita household income of up to 3 minimum wages (RR 1.27; 95%CI 1.18–1.37) and ratio of children under one year of age related to the female population aged 15 to 49 years (RR 1.09; 95%CI 1.01–1.18). Conclusion: The predicted RR for mortality from these cancers were calculated and associated with the socioeconomic conditions of the areas covered.

ABSTRACT. Cotton is one of the largest agricultural commodities that generate various sources of foreign exchange and employment worldwide. However, water deficiency is an environmental factor that limits the production of this crop, especially in semi-arid regions. We evaluated pyruvate supplementation to mitigate the effects of water stress on colored cotton. Experiments were conducted in a greenhouse. We studied two forms of pyruvate supplementation (SP1- via seed and foliar and SP2- only via foliar); three conditions of irrigation management of the plants: water restriction in the vegetative phase (VE), flowering (FL), and vegetative and flowering (VE/FL); and additional treatment (total irrigation throughout the crop cycle and without pyruvate supplementation). The experimental design included a randomized block in a 2 × 3 + 1 factorial scheme. The factors resulted in seven treatments with three replications, with a total of 21 experimental units. Gas exchange, enzyme activity, and production of components were evaluated. Water restriction in the vegetative phase does not cause losses in BRS Jade cotton when supplemented with pyruvate. However, in the flowering and vegetative phases plus flowering, it reduces gas exchange and production components and increases the activity of antioxidant enzymes in relation to plants under full irrigation. Supplementation with pyruvate via seed plus foliar (SP1) was better for BRS Jade cotton grown under water restriction.

ABSTRACT. This study was performed to investigate the effects of composted tannery sludge (CTS) on the physical properties of tropical sandy soil after seven years of CTS application. CTS was applied to a Fluvisol at five rates (0.0, 2.5, 5.0, 10.0, and 20.0 Mg ha-1) in experimental plots (sized 20 m2) with four replications. Water infiltration into the soil was determined in the field with the concentric-ring infiltrometer method. Bulk density, total porosity, macroporosity, and microporosity were determined in the soil samples. The permanent CTS application altered the physical properties of the soil and led to a decrease in bulk density. The total porosity, microporosity and macroporosity values in the CTS-applied soil ranged from 44.1-51.7, 34.6-39.4, and 9.1-12.8%, respectively. Water-infiltration rates were significantly influenced by CTS. The cumulative infiltrated water in the soil varied from 21.3-34.7 cm. The basic infiltration rate was lower in the unamended soil and increased with an increase in the rate of CTS application. This study confirmed that the physical soil parameters improved after the permanent CTS application. Therefore, this application may be a suitable strategy for improving physical soil properties over time.

ABSTRACT The aim was to evaluate the productive performance and nutrient export of maize intercropped with drought-tolerant forage grasses. The experimental design was a randomized blocks in a 2x2x2+1 factorial scheme (two forage grasses species – Massai and Buffel; two forage sowing methods - in the furrow and broadcast; and two forage sowing times - anticipated and simultaneous; and monoculture maize as an additional control), with three replicates. The maize+forage intercropping promoted greater competition for resources, especially water, limiting N uptake, chlorophyll synthesis, and biomass production by maize under semiarid conditions. Early sowing gave forage plants a competitive advantage, favoring forage establishment before or immediately after the sowing of maize. Thus, the simultaneous sowing of forage grasses in a semiarid environment is a more appropriate option considering the importance of high levels of chlorophyll to ensure high photosynthetic activity in maize plants and greater capacity of biomass synthesis. Massai intercropped with maize exhibits a greaterpotential for biomass production than Buffel under semiarid conditions. Maize+Buffel result in highest macronutrient export by maize, while maize+Massai result in highest macronutrient exports by total forage biomass under a semiarid environment. The choice of the forage species and its sowing time in relation to maize are the main determinants of successful intercropping systems under semiarid conditions.

RESUMO O objetivo foi avaliar o desempenho produtivo e a exportação de nutrientes do consórcio de milho com gramíneas forrageiras tolerantes ao estresse hídrico. O experimento foi delineado em blocos casualizados em esquema fatorial 2x2x2+1 (duas espécies de gramíneas forrageiras – Massai e Buffel; dois métodos de semeadura – no sulco e a lanço; e duas épocas de semeadura – antecipada e simultânea; e monocultivo de milho como um controle adicional), com três repetições. O consórcio milho+forragem promoveu maior competição por recursos, principalmente água, limitando a absorção de N, síntese de clorofila e produção de biomassa pelo milho para condições semiáridas. A semeadura precoce deu vantagem competitiva às plantas forrageiras, favorecendo seu estabelecimento antes ou imediatamente após a semeadura do milho. Assim, a semeadura simultânea de gramíneas forrageiras em ambiente semiárido é uma opção mais adequada, considerando a importância de garantir altos teores de clorofila e, consequentemente, alta atividade fotossintética nas plantas de milho para garantir a capacidade de síntese de biomassa.Massai consorciado com milho apresenta maior potencial para produção de biomassa do que Buffel em condições semiáridas.Milho+Buffel resulta em maior exportação de macronutrientes pelo milho, enquanto milho+Massai resulta em maior exportação de macronutrientes pela biomassa forrageira total em ambiente semiárido.A escolha da espécie forrageira e sua época de semeadura em relação ao milho são os principais determinantes do sucesso do consórcio no semiárido.
