Parròquia i societat rural al Bisbat de Girona, segles XIII i XIV

La parròquia, poc valorada per la historiografia medieval, fou una la institució fonamental per a l'ordenació de la societat rural del bisbat de Girona entre els segles X i XIV. Constituïa un territori ben delimitat, els habitants del qual rebien els sagraments eclesiàstics dels clergues que regien l'església i, a través de l'obreria i dels obrers, participaven en la gestió del temple i de la seva economia. La parròquia va incidir directament en l'ordenació del poblament rural a través tant dels nuclis eclesials o "celleres" com dels masos dispersos pel terme d'una parròquia. A més, la parròquia era una important font de rendes: a través de la documentació generada pel bisbe de Girona, el delme era una renda en mans, sobretot, de senyors feudals, cavallers i importants institucions eclesiàstiques; els clergues parroquials només rebien les primícies i altres drets de menor valor. Finalment, la parròquia contribuí enormement a la configuració de les comunitats rurals de bona part del bisbat de Girona.

Single trial BCI operation via Wackermann parameters

Accurate single trial P300 classification lends itself to fast and accurate control of Brain Computer Interfaces (BCIs). Highly accurate classification of single trial P300 ERPs is achieved by characterizing the EEG via corresponding stationary and time-varying Wackermann parameters. Subsets of maximally discriminating parameters are then selected using the Network Clustering feature selection algorithm and classified with Naive-Bayes and Linear Discriminant Analysis classifiers. Hence the method is assessed on two different data-sets from BCI competitions and is shown to produce accuracies of between approximately 70% and 85%. This is promising for the use of Wackermann parameters as features in the classification of single-trial ERP responses.

Human microbiota in health and disease

Each human body plays host to a microbial population which is both numerically vast (at around 1014 microbial cells) and phenomenally diverse (over 1,000 species). The majority of the microbial species in the gut have not been cultured but the application of culture-independent approaches for high throughput diversity and functionality analysis has allowed characterisation of the diverse microbial phylotypes present in health and disease. Studies in monozygotic twins, showing that these retain highly similar microbiota decades after birth and initial colonisation, are strongly indicative that diversity of the microbiome is host-specific and affected by the genotype. Microbial diversity in the human body is reflected in both richness and evenness. Diversity increases steeply from birth reaching its highest point in early adulthood, before declining in older age. However, in healthy subjects there appears to be a core of microbial phylotypes which remains relatively stable over time. Studies of individuals from diverse geopraphies suggest that clusters of intestinal bacterial groups tend to occur together, constituting ‘enterotypes’. So variation in intestinal microbiota is stratified rather than continuous and there may be a limited number of host/microbial states which respond differently to environmental influences. Exploration of enterotypes and functional groups may provide biomarkers for disease and insights into the potential for new treatments based on manipulation of the microbiome. In health, the microbiota interact with host defences and exist in harmonious homeostasis which can then be disturbed by invading organisms or when ‘carpet bombing’ by antibiotics occurs. In a portion of individuals with infections, the disease will resolve itself without the need for antibiotics and microbial homeostasis with the host’s defences is restored. The administration of probiotics (live microorganisms which when administered in adequate amounts confer a health benefit on the host) represents an artificial way to enhance or stimulate these natural processes. The study of innate mechanisms of antimicrobial defence on the skin, including the production of numerous antimicrobial peptides (AMPs), has shown an important role for skin commensal organisms. These organisms may produce AMPs, and also amplify the innate immune responses to pathogens by activating signalling pathways and processing host produced AMPs. Research continues into how to enhance and manipulate the role of commensal organisms on the skin. The challenges of skin infection (including diseases caused by multiply resistant organisms) and infestations remain considerable. The potential to re-colonise the skin to replace or reduce pathogens, and exploring the relationship between microbiota elsewhere and skin diseases are among a growing list of research targets. Lactobacillus species are among the best known ‘beneficial’ bacterial members of the human microbiota. Of the approximately 120 species known, about 15 are known to occur in the human vagina. These organisms have multiple properties, including the production of lactic acid, hydrogen peroxide and bacteriocins, which render the vagina inhospitable to potential pathogens. Depletion of the of the normal Lactobacillus population and overgrowth of vaginal anaerobes, accompanied by the loss of normal vaginal acidity can lead to bacterial vaginosis – the commonest cause of abnormal vaginal discharge in women. Some vaginal anaerobes are associated with the formation of vaginal biofilms which serve to act as a reservoir of organisms which persists after standard antibiotic therapy of bacterial vaginosis and may help to account for the characteristically high relapse rate in the condition. Administration of Lactobacillus species both vaginally and orally have shown beneficial effects in the treatment of bacterial vaginosis and such treatments have an excellent overall safety record. Candida albicans is a frequent coloniser of human skin and mucosal membranes, and is a normal part of the microbiota in the mouth, gut and vagina. Nevertheless Candida albicans is the most common fungal pathogen worldwide and is a leading cause of serious and often fatal nosocomial infections. What turns this organism from a commensal to a pathogen is a combination of increasing virulence in the organism and predisposing host factors that compromise immunity. There has been considerable research into the use of probiotic Lactobacillus spp. in vaginal candidiasis. Studies in reconstituted human epithelium and monolayer cell cultures have shown that L. rhamnosus GG can protect mucosa from damage caused by Candida albicans, and enhance the immune responses of mucosal surfaces. Such findings offer the promise that the use of such probiotic bacteria could provide new options for antifungal therapy. Studies of changes of the human intestinal microbiota in health and disease are complicated by its size and diversity. The Alimentary Pharmabiotic Centre in Cork (Republic of Ireland) has the mission to ‘mine microbes for mankind’ and its work illustrates the potential benefits of understanding the gut microbiota. Work undertaken at the centre includes: mapping changes in the microbiota with age; studies of the interaction between the microbiota and the gut; potential interactions between the gut microbiota and the central nervous system; the potential for probiotics to act as anti-infectives including through the production of bacteriocins; and the characterisation of interactions between gut microbiota and bile acids which have important roles as signalling molecules and in immunity. The important disease entity where the role of the gut microbiota appears to be central is the Irritable Bowel Syndrome (IBS). IBS patients show evidence of immune activation, impaired gut barrier function and abnormal gut microbiota. Studies with probiotics have shown that these organisms can exert anti-inflammatory effects in inflammatory bowel disease and may strengthen the gut barrier in IBS of the diarrhoea-predominant type. Formal randomised trials of probiotics in IBS show mixed results with limited benefit for some but not all. Studies confirm that administered probiotics can survive and temporarily colonise the gut. They can also stimulate the numbers of other lactic acid bacilli in the gut, and reduce the numbers of pathogens. However consuming live organisms is not the only way to influence gut microbiota. Dietary prebiotics are selectively fermented ingredients that can change the composition and/or activity of the gastrointestinal microbiota in beneficial ways. Dietary components that reach the colon, and are available to influence the microbiota include poorly digestible carbohydrates, such as non-starch polysaccharides, resistant starch, non-digestible oligosaccharides (NDOs) and polyphenols. Mixtures of probiotic and prebiotic ingredients that can selectively stimulate growth or activity of health promoting bacteria have been termed ‘synbiotics’. All of these approaches can influence gut microbial ecology, mainly to increase bifidobacteria and lactobacilli, but metagenomic approaches may reveal wider effects. Characterising how these changes produce physiological benefits may enable broader use of these tactics in health and disease in the future. The current status of probiotic products commercially available worldwide is less than ideal. Prevalent problems include misidentification of ingredient organisms and poor viability of probiotic microorganisms leading to inadequate shelf life. On occasions these problems mean that some commercially available products cannot be considered to meet the definition of a probiotic product. Given the potential benefits of manipulating the human microbiota for beneficial effects, there is a clear need for improved regulation of probiotics. The potential importance of the human microbiota cannot be overstated. ‘We feed our microbes, they talk to us and we benefit. We just have to understand and then exploit this.’ (Willem de Vos).

Caracterização ambiental de bancos areno-lamosos nos campos petrolíferos de Macau e Serra (RN), como subsídio às medidas mitigadoras ao processo erosivo

On Rio Grande do Norte northern coast the process of sediment transport are intensely controlled by wind and sea (waves and currents) action, causing erosion and shoreline morphological instability. Due to the importance of such coastal zone it was realized the multi-spectral mapping and physical-chemical characterization of mudflats and mangroves aiming to support the mitigating actions related to the containment of the erosive process on the oil fields of Macau and Serra installed at the study area. The multi-spectral bands of 2000 and 2008 LANDSAT 5 TM images were submitted on the several digital processing steps and RGB color compositions integrating spectral bands and Principal Components. Such processing methodology was important to the mapping of different units on surface, together with field works. It was possible to make an analogy of the spectral characteristics of wetlands with vegetations areas (mangrove), showing the possibility to make a restoration of this area, contributing with the environmental monitoring of that ecosystem. The maps of several units were integrated in GIS environment at 1:60,000 scale, including the classification of features according to the presence or absence of vegetation cover. Thus, the strategy of methodology established that there are 10.13 km2 at least of sandy-muddy and of these approximately 0.89 km2 with the possibility to be used in a reforestation of typical flora of mangrove. The physical-chemical characterization showed areas with potential to introduce local species of mangrove and they had a pH above neutral with a mean of 8.4. The characteristic particle size is sand in the fine fractions, the high levels of carbonate, organic matter and major and trace element in general are concentrated where the sediment had the less particles size, showing the high correlation that those elements have with smaller particles of sediment. The application of that methodological strategy is relevant to the better understanding of features behavior and physical-chemical data of sediment samples collected on field allow the analysis of efficiency/capability of sandy-muddy to reforestation with local mangrove species for mitigation of the erosive action and coastal processes on the areas occupied by the oil industry

Distribuição regional da ventilação pulmonar em indivíduos com insuficiência cardíaca crônica após serem submetidos a um programa de treinamento da musculatura inspiratória e sua correlação com dados funcionais

Introduction: Chagas Disease is a serious public health problem, with 5 million infected individuals in Brazil. Of these, approximately 30% develop chronic Chagas cardiomyopathy (CCC), where the main symptoms are fatigue and dyspnea. Objective: To correlate maximal exercise capacity with pulmonary function, inspiratory muscle strength and quality of life in patients with CCC. Methodology: Twelve individuals suffering from CCC were evaluated (7 men), with a mean age of 54.91± 8.60 years and the following inclusion criteria: functional class II and III according to the New York Heart Association (NYHA); left ventricle ejection fraction below 45%; clinical stability (> 3 months); symptom duration > 1 year, body mass index (BMI) < 35Kg/m2 and non-smokers or ex-smokers with a history of smoking <10 packs/day. All subjects were submitted to spirometry, manometer testing, maximal cardiopulmonary exercise testing (CPX) and a quality of life questionnaire (Minnesota). Results: A negative correlation was observed between VO2máx and MLHFQ scores (r=-0.626; p=0.03) and a positive association with MIP (r=0.713; p=0.009). Positive correlations were also recorded between MIP and spirometric variables [FEV1(r=0.825;p=0.001 ), FVC(r=0.66;p=0.01 and FEF25-75%(r=0.639;p=0.02)]. Conclusion: The present study demonstrated that in patients with CCC: VO2MAX is directly related to inspiratory muscle strength and quality of life, while deteriorating lung function is directly associated with respiratory muscle weakness

Product functions: interfaces with ergonomic design

In addition to technical quality, increasing emphasis is being placed on the importance of elements such as the appearance and meaning of products. To be successful, therefore, attention must be paid to the aesthetic and symbolic functions of objects as well as to reliability and physical quality. Study of the interfaces of these functions may provide a theoretical basis for the ergonomic design of products. The objective of this review is to attempt to establish the nature of these interfaces.

Cloreto de mepiquat, thidiazuron e ethephon aplicados no algodoeiro em Ponta Porã, MS

O objetivo do presente estudo foi avaliar os efeitos de diferentes dosagens de cloreto de mepiquat, thidiazuron e ethephon, aplicadas parceladamente no algodoeiro (Gossypium hirsutum L.) na Fazenda Itamarati, Ponta Porã, MS. As dosagens de cloreto de mepiquat foram: (0; 12,5 + 12,5 + 25,0 = 50; 25 + 25 + 25 = 75; 0 + 50 + 50 = 100; 12,5 + 62,5 + 50 = 125) g ha-1, com aplicações efetuadas aos 34, 47 e 62 dias após a emergência (DAE) em 1993/94, e aos 42, 60 e 73 DAE, em 1994/95, enquanto o thidiazuron foi aplicado quando 70% dos capulhos estavam abertos, nas dosagens de 0, 45, 60 e 75 g ha-1; já o ethephon foi aplicado sete dias após o thidiazuron, quando já se observava desfolha de 85%, nas dosagens de 0, 960 e 1.440 g ha-1. O delineamento experimental utilizado foi o de blocos casualizados em faixa, com subparcelas subdivididas e quatro repetições. O cloreto de mepiquat proporcionou redução do número de frutos verdes, aumento do peso de 100 sementes e do peso médio de um capulho; a percentagem de desfolha aumentou com as dosagens de thidiazuron e ethephon; constatou-se que a interação cloreto de mepiquat x thidiazuron x ethephon foi significativa para percentagem de abertura de capulhos e produção de algodão em caroço.

Distribuição espacial de Toxoptera citricida (Kirkaldy) (Hemiptera: Aphididae) na cultura de citros

O estudo da distribuição espacial de pragas é fundamental para elaboração de planos de amostragem para o uso do manejo integrado de pragas. Para o afídeo Toxoptera citricida (Kirkaldy), estudou-se a distribuição espacial em talhões de pomares de citros comerciais de laranja-doce [Citrus sinensis (L.) Osbeck] da variedade Pêra, com 5; 9 e 15 anos de idade, durante o período de setembro de 2004 a abril de 2005. Foram realizadas 14 amostragens de número de T. citricida em intervalos aproximados de 15 dias entre as mesmas, utilizando-se de armadilhas adesivas de cor amarela (0,11 x 0,11 m) fixadas à planta, a 1,5 m de altura aproximadamente. As armadilhas foram distribuídas na área, a cada cinco plantas na linha, em linhas alternadas, totalizando 137 armadilhas no talhão com 5 anos, 140 no talhão com 9 anos e 80 no talhão com 15 anos. Os índices de dispersão utilizados foram: razão variância média (I), índice de Morisita (Idelta), coeficiente de Green (Cx) e expoente k da distribuição Binomial Negativa. O índice que melhor representou a agregação do pulgão foi o expoente k da distribuição Binomial Negativa, e a distribuição binomial negativa foi o modelo que melhor se ajustou aos dados. Através destas análises, verificou-se que a maioria das amostragens apresentou uma distribuição agregada da população de T. citricida.

Ideais formativos de homem da emissora de Educação Rural de Caicó (Rio Grande do Norte, 1963-1978)

Under the aegis of the third diocese bishop of Caicó, Dom Manuel Tavares de Araújo, the Broadcasting Station of Rural Education of that city was founded, in May 1 s" 1963 with the ideal of being then an educational city, preferentially for youths and adults, rural meu and women of the arca of Seridó in Rio Grande do Norte state. In the year of its 40th birthday (2003), we began the investigation of that radio station choosing as study object its educational and formative programming, in the inc1usion of the first fifteen years of its existence (1963-1978), period that reaches the official inauguration of the Radio Station and the end of the bishopric of its fOllllder as Bishop of Caicó. Elucidating and showing Man's formative ideaIs longed by that Catholic educational broadcasting station, underlying to its radiophonic programming, such as the idealization for it reached, is the objective of this Doctorate work. It was considered pertinent to discover the guidelines that historically have permeated the Social Doçtrine of the Catholic Church addressing its aggiornamento, especially in what concerns to the employment of the modern ways of communication for the distance with the aim of evangelizing and educating. In arder to understand the ideaIs of the investigated educational Radio, we have delimited the research to the thematic Catholic Church, means of social communication and base education. In face of the study object and the aim to be reached it was appealed, methodologically, to the notion of cultural action present in Certeau (1995), and to the understanding of educational formation backgrounded fIam the modern thinkers that discuss it. Such frame references have allowed us to analyze in a wider spectrum tl)e programming broadcasted on the air by the sound wavys of that educ(itional Çatholic Radio, as well as, the very acts of cultural idealizations that has orientated it in its foundations. The thesis here defended is that. the Radio, at procJaiming itself as a broadcasting station of rural education directed preferably to the rural sertanejo countrymen, without neglecting its admitted ends, has surpassed them in its overall range. It was identified an articulate approach of its programmatic modules with the guid,elines emanateq from the Catholic Teaching about the use of the. means of social communication. At conceiving, establishin,g and executing an ec1ectic programmatic and div,ersified grating, the Rural Radio of Caicó has transcended to a strict human-Christian formation to request the development of the human, spiritual and cQrporaldimensions, jointly. With suchprogramming, it addressed to the seridoenses as real meu and women inserted in the "sertanej.o" environment with effective structural and existential problems of alI types, induding the hunger, the thirst, the syndical organization, the cQoperativism, the colIective modero work and the absence of universalizing school education. Its radiophonic transmissions, I}lled by the demands of an enlarged, open, dialogic and responsible communication, wheneIllbracing dedicated modules to religious and catechetical emissions, to the entertainment, to the radiojoumalism, to the country root culture, and to the school education of b se for the modality of the School and of the radiophonic classes, subsumed to ideaIs that longed for the formation of a multifaceted and pluridimensional sertanejo Man; of men and women that, without abjuring the Catholicism, were able to understand, to dialogued and to live together with the general demands of a society in progressive mutation, whose economical, social, cultural and educational demands it IDade themselves to be felt through the sertão potiguar of the Serido region, equal way of the intemationalized world

A luta do Bispo Dom José de Medeiros Delgado por educação escolar para todos (Caicó-RN, 1941-1951)

The socioeducational program of actions developed by Dom José de Medeiros Delgado, first Bishop of Diocese of Caicó city in Rio Grande do Norte, from 1941 to 1951, is analyzed by the present work in a historical perspective, based upon the school culture refecence.Through this reference point, the general and peculiar school culture proper of catholic schools founded by Dom Delgado was learned.The schools are: the Ginásio Diocesano Seridoense (1942), the Escola Doméstica Popular Darci Vargas (1943, the Prevocacional School of Caicó (1944) and the Santo Cura d ars Seminar (1946). The socioeducational actions of Dom Delgado Bishop affected seven other towns surrounding Caicó. Places where catholic schools were founded and named after Escola do Pobre . In fight for schools for all social segments of city and rural natures, Dom Delgado founded four rural schools in the surroundings of Serra Negra, São João do Sabugi, Jardim do Seridó e Lagoa Nova. It is also part of his beneficial work the creation of rural cooperatives for the parents of the students from such schools

Estimativas de parâmetros genéticos para os escores visuais e suas associações com peso corporal em bovinos de corte

Foram avaliados 27.523 e 21.746 registros das características conformação, precocidade e musculatura à desmana e ao sobreano, respectivamente, para estimar os componentes de covariância entre estas características e entre estas e os pesos corporais medidos nas mesmas idades. Para as análises dos dados, foram empregados modelos animais com efeitos genéticos direto e materno e efeito de ambiente permanente materno. Máxima verossimilhança restrita foi empregada para estimar os parâmetros genéticos. As estimativas de herdabilidade dos escores à desmama foram 0,13; 0,25 e 0,23 para conformação, precocidade e musculatura, respectivamente. As estimativas de herdabilidade dos escores visuais avaliados ao sobreano foram de maiores magnitudes (0,24; 0,32 e 0,27 para conformação, precocidade e musculatura, respectivamente). As estimativas das correlações genéticas entre escores medidos às mesmas idades, considerando desmana e sobreano, foram 0,67 e 0,75 entre conformação e precocidade; 0,61 e 0,71 entre conformação e musculatura; 0,95 e 0,95 entre precocidade e musculatura. As correlações genéticas estimadas entre o peso corporal à desmama e conformação, precocidade e musculatura, respectivamente, foram 0,97; 0,67 e 0, 62. As estimativas entre conformação, precocidade, musculatura ao sobreano e o peso corporal foram 0,83; 0,59 e 0,58, respectivamente. Os resultados indicam que os escores visuais podem ser utilizados como critérios de seleção. Aumento nos pesos corporais deve ser esperado como resposta correlacionada à seleção para essas características.

Manejo químico de Eichhornia crassipes e Brachiaria subquadripara com Diquat em condições de reservatório

Este trabalho teve como objetivo avaliar a eficiência do herbicida diquat no controle de plantas de Eichhornia crassipes e Brachiaria subquadripara em condições de reservatório. As parcelas experimentais apresentavam 650 m² e foram delimitadas e posicionadas por redes de pesca nas margens do reservatório de Salto Grande, Americana-SP. Os tratamentos testados foram: herbicida diquat aplicado na formulação Reward, nas doses de 960 g i.a. ha-1 (duas aplicações de 480 g, com intervalo de 15 dias), 960 g i.a. ha-1 (aplicação única), 1.920 g i.a. ha-1 (duas aplicações de 960 g, com intervalo de 15 dias), além de uma testemunha sem aplicação do herbicida. Para monitoramento das concentrações de diquat, foram coletadas amostras de água antes da aplicação do herbicida e 1, 2, 4, 7, 14 e 28 dias após aplicação (DAA) na área experimental e na montante e jusante da barragem. A análise da eficiência do diquat foi realizada através de avaliações visuais de controle no período (1, 2, 4, 7, 14, 21 e 28 DAA do herbicida) e aos dois dias após a segunda aplicação. O herbicida diquat mostrou-se eficiente no controle das plantas de E. crassipes, independentemente da dose e do manejo de aplicação, e seu efeito sobre as plantas de B. subquadripara foi temporário.

Desenvolvimento de mudas de Tabeluia chrysotricha em função de substratos e de soluções de fertirrigação

The work aimed to study the development of Tabebuia chrysotricha Standl. seedlings injunction of different substrate and different fertilization solutions. To compose the substrate it was used fibrous and granulated coconut fiber obtaining the following treatments: S1- 100% fibrous, S2- 60% fibrous and 40% granulated, S3- 40% fibrous and 60% granulated and S4- 100% granulated. The basis fertilization was the same for all treatments and the solutions of fertilization varied in order to obtain solutions with the following electric conductivities: EC1- 1.06 dS m(-1), EC2- 2.12 dS m(-1), EC3- 3.2 dS m(-1) and EC4- 4.25 dS m(-1). The propagative material was sowed directly in plastic containers (120mL) with the respective substrates. The fertilization was received through sub irrigation once a week, until the seedlings reached 20cm of height approximately. The chemical analyses of the substrate (EC and pH), through aqueous extraction method 1:1.5 (1 substrate: 1.5 deionized water), the analyses of aerial part height, stein diameter and pairs true leaves number, as well as the weight of total dry, matter, were accomplished each 15 days. In almost every analysis, the substrate with granulated coconut fiber, as well as the smallest EC (1.06 e 2.12 dS m(-1)) of fertilization solutions,formed seedlings with higher averages, indicating faster growth. In the conditions of this experiment, the production of T. chrysotricha seedlings was better in granulated coconut fiber substrate and fertilizer solutions with EC of 1.06 dS m(-1), appreciating the estimated characteristics.

Modos de aplicação de calcário e de micronutrientes em pomar de laranjeira 'Natal' e análise comparativa de custos

De acordo com o Agrianual (2005), a produção citrícola brasileira é de 17,7 milhões de toneladas ano-1,ocupando aproximadamente 1 milhão de hectares no território brasileiro e, deste total, 810 mil hectares localizam-se no Estado de São Paulo. A maioria dos solos brasileiros, inclusive aqueles onde foram instalados os pomares cítricos, apresenta reação ácida. Esta é, sem dúvida, a principal condição desfavorável dos solos e um dos fatores limitantes da produção em solos tropicais. O presente trabalho teve por objetivo estudar o efeito de diferentes modos de aplicação de calcário e de micronutrientes e analisar, de forma comparativa, os custos destes tratamentos em um pomar de laranjeira. O experimento foi desenvolvido na Fazenda Morumbi, município de Estrela D'Oeste-SP, num Argissolo Vermelho-Amarelo. A variedade de laranjeira utilizada foi a 'Natal', enxertada em limão Cravo, com 6 anos de idade e espaçamento 5 x 8 m. O delineamento experimental foi em parcelas subdivididas, com 3 repetições, com 5 tratamentos principais (sem calcário; a necessidade total de calcário (NC) incorporado; NC sem incorporação; ¹/2 NC no primeiro ano + ¹/2 NC no segundo ano e ¹/3 NC no primeiro ano, + ¹/3 NC no segundo ano, + ¹/3 NC no terceiro ano) e dois tratamentos secundários [micronutrientes via solo (FTE-BR 12: 11,5 % de ZnO e B2O3; 1% CuO; 5,4% de Fe2O3; 5,5% de MnO2; 0,2% de MoO3) e micronutrientes via foliar (sulfato de zinco a 0,5% e ácido bórico a 0,08%)], distribuídos em blocos casualizados. Não houve efeito significativo dos modos de aplicação da calagem e de micronutrientes sobre as variáveis avaliadas (produção, sólidos solúveis totais, acidez total titulável). Para massa média do fruto, o efeito significativo aconteceu apenas no primeiro ano, com a calagem em dose única e sem incorporação, e micronutrientes via solo. Concluiu-se que não houve efeito significativo dos modos de aplicação do calcário e dos micronutrientes para produção e massa média dos frutos da laranjeira 'Natal', e a receita líquida foi positiva em todos os tratamentos, sendo que o tratamento 5 [¹/3 da necessidade total de calcário (NC) no 1º ano + ¹/3 da NC no 2º ano, + ¹/3 da NC no 3º ano] apresentou o melhor valor acumulado (U$ 3.721,85 ha-1).
