Published: July 2019

Resumo Esta pesquisa teve como objetivos a adaptação transcultural e avaliação das propriedades psicométricas da versão brasileira do Reno Inventory of Self-Perspective - RISP, instrumento que avalia a habilidade de tomada de perspectiva, compreensão de si mesmo enquanto construção contextual, por meio dos fatores enredado, centrado e transcendente. A amostra foi composta por 344 universitários (idade 21,1 ± 4,8; 64,2% mulheres). A estrutura interna foi estimada por meio do Exploratory Structural Equation Modeling (ESEM). Também se avaliou a invariância do modelo fatorial entre participantes do sexo masculino e feminino, indicadores de precisão e associação com variáveis externas: satisfação com a vida, fusão cognitiva, ansiedade, estresse e depressão. Os resultados revelaram a estrutura composta por três fatores, conforme hipótese teórica, com indicadores desejáveis de precisão. Foi demonstrado equivalência do modelo de medida ao avaliar participantes dos diferentes sexos, e associações correspondentes as perspectivas teóricas com as variáveis externas estudadas. Os resultados sugerem adequação da versão brasileira RISP.

Published: July 2019

Abstract This study aimed to correlate, compare and identify the family, personal and demographic variables that may predict behavioral problems in adolescents. A total of 300 adolescents participated, 230 with behavioral problems (177 girls and 53 boys; M= 14.00 years; SD=1.24) and 70 without (47 girls and 23 boys; M=14.09 years; SD=1.33). Data was collected through questionnaires and inventories completed by adolescents and analyzed using Pearson’s correlation, Student’s t-tests and multiple binary logistic regression. Results showed low self-control as a risk factor and social skills and low frequency of physical abuse and maternal neglect as protection factors. The model evaluated had a reasonable predictive power (79.9%, specificity 93.9% and sensitivity 34.3%). The findings contribute to the prevention of behavioral problems in adolescents.

Published: July 2019

Abstract The contemporary work context is characterized by unpredictability, thus requiring the ability of individuals to adapt to changes imposed by the market. Career adaptability refers to the individual’s ability to handle working transitions in turbulent times. This study aimed to test the structural invariance of the last Brazilian version of the Career Adapt-Abilities Scale (CAAS) according to sex and observe possible differences between men and women in the dimensions of adaptability. The sample consisted of 599 Brazilian professionals, of both sexes, with higher education level. The CAAS was subject to confirmatory factor analysis and invariance testing, demonstrating structural invariance according to sex. A subsequent MANOVA evidenced the lack of differences between men and women in the four dimensions of the CAAS. Results corroborate the consistency and reliability of the CAAS as an instrument for measuring career adaptability in both sexes.
Marital Social Skills and Marital Satisfaction of Women in Situations of Violence
Authors: Cardoso Bruno Luiz Avelino , Costa Nazaré
Published: July 2019

Abstract Marital Social Skills (MSS) are related to Marital Satisfaction (MS). However, abusive relationships present a deficit in the use of health strategies for conflict management and damages to those involved. This study evaluated in 23 women, with an average age of 35 years, in situations of intimate partner violence, the MSS, MS and the forms of violence suffered. For this, it used the MSS Inventory, MS Scale and a Violence Questionnaire. The results showed a predominance of psychological violence, a high level of marital dissatisfaction and a deficient repertoire of MSS. Negative correlation was identified between MSS, Proactive Self-Control and Marital Dissatisfaction; positive correlation between Assertive Conversation and Marital Dissatisfaction (and Marital Interaction) and negative correlation between Self-Assertiveness, Proactive Self-Control and situations of violence. Thus, the importance of specific MSS training for this population and the understanding of the nature of assertive responses in the sociocultural context is noted.
The strategic use of the scope of justice in legitimizing intergroup conflict
Authors: Lima-Nunes Aline , Farias Kamila Gadelha
Published: July 2019

Resumo O presente estudo buscou analisar como a percepção do escopo de justiça, a partir da influência da posição grupal, pode ser utilizada para legitimar a exclusão social. Participaram 103 estudantes universitários com idade entre 18 e 30 anos (M = 20,44, DP = 1,98). O estudo foi composto por duas condições experimentais: os participantes justificavam a situação colocada por uma condição experimental (restrição do escopo de justiça) ou controle (observadores) por meio de questionários. Realizou-se a análise de conteúdo das justificativas encontradas. Os resultados mostraram que, na condição de restrição, aconteceu a legitimação da posição hegemônica do grupo dominante através de discursos meritocráticos. No grupo controle, os participantes percebiam a desigualdade social e sugeriam ampliar o escopo de justiça, ou seja, não-restrição de direitos para determinados grupos. Dessa forma, identifica-se o uso estratégico de argumentos de justiça como a ampliação/restrição do escopo de justiça para justificar as desigualdades sociais de acordo com determinada posição grupal.

Published: July 2019

Abstract The study aimed to investigate the association of risk and protection factors in the academic performance and life satisfaction of elementary school students. Participants included 400 students of both sexes, aged between 11 and 17 years, and 26 female teachers from public and private schools in the state of Rio de Janeiro. The instruments were: Social Skills Inventory for Adolescents, Social Support Perception Scale, Brazilian Youth Questionnaire and Maslach Burnout Inventory. Main results showed that exposure to family violence by the students, emotional exhaustion and low professional achievement by the teachers contribute to a poor performance of students in school. Students with indicators of social support by the family and the community and of self-control skills presented higher life satisfaction. This study reveals contextual and personal variables that affect students’ socio-emotional and academic development which prove subsidies for future interventions.

Published: July 2019

Abstract Emotion regulation is a multiprocessual phenomenon capable of maintaining, intensifying or diminishing the emotional experience. This work investigated the psychometric properties of the Emotion Regulation Inventory for Learning Situations, using the Item Response Theory (IRT). Participants included 365 students from the 5th to the 9th grades of elementary school, with a mean age of 11.9 years (SD = 1.72), 57.5% female and 42.5% male. The results indicated problems in the instrument, such as small variability of the items and underutilized categories of response, and ways for the revision of the instrument, such as construction of more difficult items that require internal strategies, focused on the learning experience.

Authors: Silva Filho André Luis Amorim , Ferreira Maria Cristina , Valentini Felipe
Published: July 2019

Abstract The study gathered evidence of validity based on the internal structure and relations with external variables of the Ethical Leadership Behavior Scale. The study participants were 405 workers of both sexes (64.7% female), aged 19-69 years (M = 35.7; SD = 10.9), who answered the Brazilian version of the scale and instruments to assess other constructs. The confirmatory factor analyses pointed to a final version of 35 items concentrated in a single factor, with an internal consistency index of 0.96. In the validity evidence in relation to external variables, the scale was positively and moderately correlated with work engagement, job satisfaction, and affective organizational commitment; weakly and positively with general mental health; and weakly and negatively with burnout. The future use of the scale in organizational research and diagnostics on ethical leadership behavior is recommended.

Published: July 2019

Abstract This article gathered evidence of the validity of the Internalized Homophobia Scale (EHI) for Brazilian gays and lesbians. Study 1 found evidence of content validity (performed by two area judges and 10 gay and lesbian people), based on the internal structure and still sought reliability/precision indicators of the instrument. Based on an online survey, 261 participants, with a mean age of 27.6 years (SD = 7.72), answered IHS and sociodemographic questions. Study 2 replicated the factorial solution from study 1, through confirmatory factorial analysis, in addition to seeking complementary evidence of construct validity and reliability, being carried out with 303 gays and lesbians, with a mean age of 30.6 years (SD = 8.29). The results of the two studies suggest a modified version of the IHS with 19 items and two dimensions (Internal Perception of Stigma and Perception [α = 0,814] of Social Oppression [α = 0,622]) because it presented evidence of validity and reliability/precision of the instrument.

Published: July 2019

Abstract Self-determination Theory (SDT) has an organismic and dialectical framework for the study of personality growth and development. From SDT’s perspective, individuals are prone to develop towards an active and integrative way. Therefore, there are three basic needs that must be satisfied: autonomy, relatedness and competence. Through the association between personal characteristics and the satisfaction of needs development and integration will be allowed. This paper will discuss SDT precepts and how the satisfaction of these needs reverberates throughout development.

ABSTRACT This study represents a first attempt to rescue germplasm of a traditional domestic equine cited in early Iberian and South American literature as Curraleiro horse. As an effort to identify and possibly characterize this type of horse we accessed traditional knowledge in strategic rural areas. Most areas were configured by hinterland settlements founded by runaway slave communities from the sixteenth century. Twenty interviews were conducted and analyzed using classical Speech Content Analysis. As a result, five response categories were recognized: 1) Identification and location of Curraleiro horses; 2) Characterization of Curraleiro horses; 3) Historical aspects; 4) Curraleiro horse conservation prospects and 5) Sanitary and productive aspects of Curraleiro horse breeding. We concluded that although scarce, the Curraleiro horse, cited in literature, still exists and showed phenotypical features which allow fine discrimination from any officially recognized breed in Brazil. Our findings may open the door for the recognition of a genuine animal resource which could play a role in rural development for specific regions and traditional communities. Speech Content Analysis was effective for in loco identification and characterization of rare traditional livestock. Thus, we encourage the usage of this tool as an alternative to subsidize identification and genetic conservation programs worldwide.

RESUMO Os colágenos tipos I e III apresentam diferentes tonalidades de birrefringência em cortes histológicos corados com Picrosirius red e analisados em microscópio sob luz polarizada. Com base nessa propriedade, os colágenos podem ser quantificados por histomorfometria. Entretanto, são muitas as variáveis que podem afetar a distribuição das cores na imagem histológica, e a escolha adequada dos parâmetros de análise têm grande influência no resultado final. O objetivo deste trabalho foi comparar a quantificação histomorfométrica de colágeno em pele equina pela morfometria por contagem de pontos e pela segmentação de cor com diversas configurações, a fim de se determinar o melhor método de avaliação. Para a morfometria por contagem de pontos, foram utilizadas três gratículas diferentes (391, 588 e 792 pontos de interseções) e, para a segmentação de cor, seis combinações de hue e brightness no software ImageJ. Os valores foram submetidos ao teste de Friedman, seguido pelo teste de Tukey com 5% de significância. Os resultados demonstraram que a quantificação dos colágenos na gratícula de 792 pontos foi equivalente aos resultados da segmentação de cor com brightness de 1-255 e hue de 0-42 e 43-120 para os colágenos tipos I e III, respectivamente. Dessa forma, conclui-se que a análise automática da segmentação de cor, utilizando configuração adequada para brightness e hue, pode substituir a morfometria por contagem de pontos de forma confiável e segura.

RESUMO O objetivo do presente trabalho foi avaliar a conversão alimentar, a digestibilidade do amido, o comportamento ingestivo e o escore de sobras da dieta e de fezes de novilhos confinados, suplementados com doses do complexo enzimático (0; 2,5; 5,0 e 7,5g animal-1 dia-1) e alimentados com dieta constituída por 85% de grão de milho e 15% de núcleo proteico, vitamínico e mineral, na base seca, isenta de forragem. O delineamento experimental foi o de blocos ao acaso contendo quatro tratamentos e quatro repetições. Trinta e dois novilhos inteiros, ½ sangue Angus Nelore, com idade média de 12 meses e peso vivo médio inicial de 422kg, foram confinados por um período de 77 dias. Cada grama de inclusão de complexo enzimático melhorou a conversão alimentar em 0,1652%, reduziu a matéria seca das fezes em 0,4648% e o tempo de ingestão de água em 0,0068 horas dia-1. A máxima digestibilidade do amido foi alcançada na dose de 5,08g animal-1 dia-1. A inclusão progressiva do complexo enzimático à dieta de alta densidade energética promoveu melhoria na conversão alimentar, redução na matéria seca das fezes e diminuição do tempo de ingestão de água. A dose de 5g animal-1 dia-1 do complexo enzimático aumentou a digestibilidade do amido.

ABSTRACT Due to the doubts and questions about the inflammatory reaction caused by chemical castration, this study aimed to use infrared thermography to detect, evaluate and monitor the inflammatory reaction caused by the intratesticular injection of calcium chloride (CaCl2) 20% with lidocaine 1%. For this, thermographic measurements were taken before (M0), 10 minutes (M1), 1 and 6 hours (M2 and M3), for 7 consecutive days (M4 to M10), at 15 (M11), 30 (M12) and 60 (M13) days after intratesticular injection. Additionally, changes to testicular tissue and effects over spermatogenesis were evaluated by andrological exam before (M0) and 60 days (M13) after intratesticular injection. All cats were orchiectomized at M13, and testicles were submitted to histological analysis. CaCl2 (20%) with lidocaine (1%) administration produced testicular tissue damage and interfered with the spermatogenesis in 70% of treated cats without exacerbating the inflammatory reaction or impairing the cat’s welfare. It was concluded that thermographic evaluation is a useful, efficient, easy and quick method to diagnose and monitor cat testicular inflammatory reactions.
ETHICAL CLIMATE INDEX: EVIDENCE OF VALIDITY OF THE BRAZILIAN VERSION
Authors: ALMEIDA JULIANA G. , PORTO JULIANA B.
Published: July 2019

ABSTRACT Purpose: Ethical issues have been a growing concern in Brazilian organizations. One of the variables that have been studied in this field is the Ethical climate. Victor and Cullen’s (1988) measure is the one most applied to address this phenomenon. This scale has been criticized because its structure has not been empirically supported and the need for update measures has been highlighted. As an answer to this critique, Arnaud (2010) proposed the Ethical climate index - the ECI. This measure uses Rest’s (1984) model of ethical decision-making as a background. The main goal of this work was to develop a Brazilian version of the ECI. Originality/value: The ECI does not yet have a Brazilian version. Design/methodology/approach: The first study presents the translated measure, an exploratory and confirmatory study of the factorial structure on a sample of 1,306 employees. In Study 2 (sample of 3,087 employees), we performed first and second order confirmatory analyses of the structure found in Study 1 in a different sample. Findings: The original model showed better goodness of fit in both studies. Additionally, relationships with ethical leadership and abusive leadership were identified. Overall, findings suggest the scale presents good psychometrical properties, presenting itself as a good measure to evaluate ethical climate.

Authors: KLEIN LEANDER L. , PEREIRA BRENO A. D. , LEMOS RICARDO B.
Published: July 2019

ABSTRACT Purpose: This study aims to analyze the parameters of the Quality of Working Life (QWL) evaluation in a public organization and the perception of the employees in relation to these factors. Originality/value: The article advances in the theoretical evaluation of QWL in a public context and expanding the presentation of parameters in the job environment. In practice, we present some behavior patterns in different groups of analysis. So, we deepen the understanding of assumptions and hypotheses already existing in theory and propose new ones regarding the standards of QWL. Design/methodology/approach: Ferreira’s (2011) model was taken as the basis for the development of empirical research. The method of this work is quantitative research, whose data collection was performed through the use of a questionnaire. The analysis of the data was performed mainly through the T and ANOVA tests. Findings: As the main results, it is possible to highlight the 9 factors obtained from the exploratory factorial analysis. In addition, there have been some different perceptions of groups of servers regarding these factors. From this, it is concluded that the evaluation of the QWL and its parameters is perceived differently between servers when they are grouped in groups with different characteristics.

Authors: FRANCISCHETO LEELA L. , NEIVA ELAINE R.
Published: July 2019

ABSTRACT Purpose: Test the influence of cultural orientation to innovation on the number of innovations measured in Brazilian companies. Originality/value: The study uses an approach that has not yet been explored in the area, the multilevel analysis. Design/methodology/approach: Five cultural orientation factors for innovation were considered: Rituals and Stories; Innovation strategies; Symbols and Heroes; Autonomy; and Standards and Communication. Innovation has been subdivided into four types: product, service, technology, and administration. The study consisted of a sample of 345 individuals in 60 organizations. The relationship between variables was analyzed using both linear regression and multilevel modeling. Findings: The results of the regression analysis showed positive and negative relationships of all cultural factors with some kind of innovation. The multilevel analysis indicated a relationship between the two variables only in the factors Rituals and Stories and Symbols and Heroes, both at the individual level. The study indicates the existence of organizational culture characteristics that favor and inhibit innovation. In addition, the complexity of the subject and the consequent need for further studies are highlighted.

Published: July 2019

ABSTRACT Purpose: The aim of this article is to identify which factors encourage and/or discourage companies to operate as a network, based on the Technology, Innovation and Knowledge Firms Network (TIKFN). Originality/value: Few advances have been made in the literature to understand the technology-based firms’ cooperation networks (TBFs), which have different characteristics, especially in relation to levels of uncertainty and innovation. Design/methodology/approach: It was conducted a Study Case on this paper. Therefore, data were collected through documents, semi structured questionnaires and focal groups to assure data source triangulation. Additionally, data analysis consisted of networks structural analysis, regression analysis and content analysis by frequency and category. Findings: Among the observed results, it is noticeable that congruence of objectives, length of participation and network strengthening represent the encouraging factors for network operation. On the other hand, asymmetric interests, low actors’ engagement and lack of active management are the discouraging factors. In order to assure the credibility of this study, results were evaluated through two focal groups composed by the network managers and participants, thus increasing the authenticity of the study. Results can be considered relevant as they contribute to understand the behavior of technology companies in a network, whose characteristics differ from other interorganizational networks especially regarding uncertainty levels and access to resources and information.

Published: July 2019

ABSTRACT Venturi injectors are commonly employed for fertigation purposes in agriculture, in which they draw fertilizer from a tank into the irrigation pipeline. The knowledge of the amount of liquid injected by this device is used to ensure an adequate fertigation operation and management. The objectives of this research were (1) to carry out functional tests of Venturi injectors following requirements stated by ISO 15873; and (2) to model the injection rate using dimensional analysis by the Buckingham Pi theorem. Four models of Venturi injectors were submitted to functional tests using clean water as motive and injected fluid. A general model for predicting injection flow rate was proposed and validated. In this model, the injection flow rate depends on the fluid properties, operating hydraulic conditions and geometrical characteristics of the Venturi injector. Another model for estimating motive flow rate as a function of inlet pressure and differential pressure was adjusted and validated for each size of Venturi injector. Finally, an example of an application was presented. The Venturi injector size was selected to fulfill the requirements of the application and the operating conditions were estimated using the proposed models.

Published: July 2019

ABSTRACT Information about local head loss caused by connections employed in micro-irrigation systems is hard to be found in literature. The objective of this research was to experimentally determine the local head losses in connections commonly used in micro-irrigation and propose mathematical models using the theorem of Buckingham. The methodology of tests was based on international standards. The tests were carried out under controlled inlet pressure, at 150 kPa, and five to ten units of each connection model were tested. The curves relating flow and head losses were drawn based on 15 flow conditions, obtained under increase and decrease of flow rate. For each condition, 30 points were collected resulting in a sample size of 900 points in each test. For each connection model evaluated, the following information was obtained: curves of local head loss as a function of flow rate and of local head loss coefficient (KL). The obtained values of KL ranged from 2.72 to 24.16, which become constant for Reynolds number higher than 10,000. The sensitivity of the coefficient related to a ratio of the internal sections in the connections was also verified. The flow exponents presented values close to the one applied by the Darcy-Weisbach equation (m = 2). The models developed for the connections presented a satisfactory performance.

Published: July 2019

ABSTRACT Based on historical series, for each locality, equations can characterize the relationship between intensity, duration and frequency of rainfall occurrence. The objective of this study was to present two equations that can describe the occurrence of intense rainfall in Pelotas, RS state, over the period 1982-2015. The two equations were denominated conventional and hybrid, depending on the probabilistic model used. Following the conventional methodology, the parameters of Normal, Log-Normal, Gumbel and Gamma probability distributions were adjusted by the maximum likelihood method for return periods of 2, 5, 10, 20, 25, 50 and 100 years. The maximum intensity values for the hybrid equation were obtained using the empirical model of Weibull, considering return periods of 2, 5, 10, 20 and 25 years. On the other hand, the same theoretical distributions used in the conventional equation were applied to return periods of 50 and 100 years. The Kolmogorov-Smirnov test was used to select the best fitting distribution for the data. In order to verify the information acquired through the Weibull empirical model in comparison to the theoretical distributions, the t-test was applied to the angular coefficients. Significant differences were not verified between the values of maximum rainfall intensities obtained using the two methodologies, for the pre-established durations and return periods. Thus, considering the maximum rainfall intensities values (durations of 5-1440 min) and return periods of 2-100 years in the municipality of Pelotas, RS, Brazil, both the hybrid and the conventional intense rainfall equations can be used.

ABSTRACT Rainfall intensity-duration-frequency (IDF) relationships are a tool that can be used in modeling the transformation of rainfall to runoff, required for the design of hydraulic works. The objective of this study was to verify if there is a significant difference between the intensity-duration-frequency relationships generated using pluviographic records and those determined from pluviometric data. Maximum annual rainfall intensity values were obtained from the disaggregation of maximum daily rainfall and rainfall records in the durations of 5, 10, 15, 20, 30, 60, 120, 360, 720 and 1440 min and for the return periods of 2, 5, 10, 20, 25, 50 and 100 years, in the locality of Pelotas, Rio Grande do Sul state, Brazil (31° 46’ 34’’ S; 52° 21’ 34’’ W, altitude of 13.2 m). By Student’s t-test, it was verified that there is no significant difference between the values of maximum rainfall intensity obtained from pluviographic records and those determined from pluviometric data.

ABSTRACT The aluminum source to produce toxicity in upland rice in nutrient solution experiments is not yet well established, althought the aluminum potassium sulfate has been utilized source to produce aluminum toxicity. However, in recent studies have used aluminum chloride. The aim of this study was to evaluate the capacity of aluminum sources and doses to produce toxicity in upland rice plants grown in nutrient solution. The experiment was arranged in a block randomized design, in a 2 x 5 factorial scheme and four repetitions. The treatments were two aluminum sources (aluminum potassium sulfate - AlK(SO4)2.12H2O and aluminum chloride - AlCl3.6H2O) and five aluminum doses in nutrient solution (0, 370, 740, 1100 and 1480 μmol L-1). The experiment was conducted in a greenhouse in Botucatu city, São Paulo state, Brazil, starting in April 2012, and was carried out for 56 days from transplanting of the seedlings. Using aluminum chloride, the rice plants show lower production of root and total dry weight, area and root volume, medium and thick root length, potassium and sulfur contents and accumulations. Using aluminum potassium sulfate, there are lower aluminum activity and availability, besides the formation of large amount of aluminum compounds non-toxic to the plants (aluminum sulfate) in the nutrient solution. The aluminum doses between 1100 to 1480 µmol L-1, corresponding to aluminum activity of 336.8 to 429.0 µmol L-1 of aluminum chloride as source, are more effective to produce aluminum toxicity in upland rice plants grown in nutrient solution.

ABSTRACT The lack of phosphorus in soil affects the development and productivity of plants; however, in order for them to express the full potential, it is necessary to supply this nutrient. The objective of this study was to define adequate doses of phosphorus, which maximize the productivity and quality of four beet cultivars, and to identify among them the most efficient use of phosphorus. The experiment was carried out at the Rafael Fernandes Experimental Farm, of the Federal Rural Semi-Arid University, Mossoró, RN state, Brazil, from July to October 2016. The experimental design was a randomized block in a 4 x 4 factorial scheme with four repetitions, corresponding to four beet cultivars (Early Wonder, Fortuna, Kestrel and Cabernet) and four doses of phosphorus (0, 90, 180 and 270 kg ha-1 of P2O5). The dose that maximized commercial productivity was 186 kg ha-1 of P2O5 for the cultivars Early Wonder (21.71 t ha-1) and Kestrel (22.59 t ha-1), 180 kg ha-1 of P2O5 for Carbenet (25.82 t ha-1) and 183 kg ha-1 of P2O5 for Fortuna (25.40 t ha-1). The Cabernet and Fortuna cultivars were classified as not efficient but responsive, whereas Early Wonder and Kestrel were efficient but not responsive. Phosphorus did not influence content of soluble solids and percentage of white rings at the root.

ABSTRACT The choice of a maize hybrid, considering the technology level and irrigation management, contributes to the improvement of the plant productivity and water use efficiency (WUE). Thus, the objective of this study was to evaluate the effects of irrigation depths on production components, grain yield, technical efficiency, and WUE in maize hybrids. The experiment was conducted in Santiago, RS state, Brazil, in the 2015/2016 and 2016/2017 crop seasons, using a randomized block design in factorial scheme, consisting of five irrigation depths (0, 50, 75, 100 and 125% of crop evapotranspiration - ETc) and four maize hybrids in crop season I (2015/2016), and six maize hybrids in crop season II (2016/2017). The number of ears per plant, number of grains per ear, 100-grain weight, grain yield, and WUE were evaluated. The irrigation depths affected the 100-grain weight, grain yield and WUE in both crop seasons, and the number of grains per ear in crop season I. The irrigation depths increased the productive performance of the maize hybrids from 9.9 to 41% when using irrigation depths of maximum technical efficiency, which varied from 90.1 to 105.4% ETc. The AG9025, P1630 and DKB290 maize hybrids presented the best agronomic performances, with grain yields from 13,609.1 to 16,281.3 kg ha-1.

ABSTRACT Extreme natural events influencing soil water availability are major factors limiting yield and oil quality in oilseed crops. The aim of the present study was to assess the effect of water deficit and surplus water on yield, oil content and on the fatty acid profile of sunflower plants sown in main and second crop seasons in two soil classes in Rio Grande do Sul State. The experiment was carried out in Santa Maria, RS (Ultisol) and Panambi, RS state, Brazil (Oxisol), Brazil, and comprised three water conditions (water deficit, water surplus and control) in a randomized block design. The hybrid Helio 250 was sown in early September (main crop season) and in early January (second crop season) in both soil classes. Yield, yield components, oil content, oil yield and fatty acid profile were herein analyzed. Yield and yield components were affected by water conditions, sowing dates and soil class. The soil class had no significant effect on oil content, yield or quality. Water deficit was more harmful to oil yield and quality than water surplus. Water deficit was responsible for increased oleic fatty acid contents and for linoleic content reduction.

ABSTRACT Soil resistance to penetration (PR) is an indirect measure of the state of soil compaction. Thus, the objective of this study was to characterize PR in vertical profiles in an area cultivated with sugarcane using multifractal models for different relief units. The experiment was carried out in an Oxisol with a clay texture, with 6.85 ha in the municipality of Coelho Neto (Maranhão state, Brazil), where 60 sampling points were demarcated. The area was divided into four relief units (Type A > 74 m, Type B from 71 to 74 m, Type C from 68 to 71 m and Type D from 65 to 68 m). The PR was measured at the 60 sampling points using an impact penetrometer, and the PR determined in the 0-0.60 m depth layer every 0.01 m. The multifractal analysis was performed considering the scale property of each profile and typified the singularity and Rènyi spectra estimated using the current method. Multifractal analysis allowed the identification of patterns at different scales and with high heterogeneity. The multifractal behavior was represented by the singularity spectrum (α), versus f(α), and the generalized dimension (Dq). The multifractal analysis allowed the differentiation between the profiles of the relief units (Types A, B, C and D), resulting in an important tool for studies of soil resistance to penetration.

ABSTRACT Soil quality indicators related to water erosion reduction can assist with correct soil management. The objective of this research was to identify some variables that could be used as soil quality indicators with the aid of path coefficient analysis in order to reduce water erosion. The research was carried out in the field between May 2011 and April 2013 in southern Brazil on an Inceptisol. The following treatments were studied under simulated rainfall conditions: 1) no-tilled, cultivated and covered by cultural residue of ryegrass (Lolium multiflorum) (HCR); 2) no-tilled, cultivated and covered by crop residue of vetch (Vicia sativa) (HCV); 3) cultivated and scarified soil containing ryegrass roots (HRR); 4) cultivated and scarified soil containing vetch roots (HRV); and 5) bare and chiselled soil (BHR). Eight simulated rainfalls were applied in each treatment. Flow velocity, soil and water losses as well as variables or soil attributes influenced by management were quantified. Path coefficient analysis verified that the coverage, surface roughness, water infiltration rate and total organic carbon have the greatest direct or indirect relationships with soil and water losses or runoff velocity. These variables were indicative of soil quality, particularly its resistance to water erosion. In a rough soil, the total organic carbon, root mass and macroporosity of the soil are more important as indicators for soil resistance to water erosion.
