Desempenho de três variedades de soja na região dos tabuleiros costeiros no estado Alagoas

The objective of this work, the performance of three varieties of soybean on "Tabuleiros Costeiros" State of Alagoas. The installation of the experiment occurred on March 20, 2006, picking up the parcels on 26 August 2006. The experimental design was a randomized blocks with seven repetitions. The experimental plots consisted of ten rows of 4.0 m in length, spaced 0.50 m. In ten plants per plot were marked certain height of the plant in full bloom stage R2 and point of harvest stage R9 considering the distance between the soil surface and apical end of the main stem, the body weight of 100 seeds, grain production and dry weight in (kg ha(-1)) which are calculated from the production harvested per plot. The soybean plants of three varieties showed height below the minimum required for mechanical harvesting. The three varieties yield or more of the traditionally producing. The average of dry matter accumulation obtained show the variety BRS Tracaja as a good option for the production of forage.

Efeito da adubação fosfata sobre o acúmulo de biomassa e teor de brix de duas variedades de cana-de-açúcar

The objective of this study was to evaluate the accumulation of matter, dry matter content of Brix and two varieties of sugar cane, influenced by the phosphorus cultivated on "Zona da Mata" region, State of Alagoas. The experiment, a factorial 2 x 6, was composed of two varieties of cane; RB867515 and RB92579 and six phosphorus levels: zero, 30, 60, 90, 120 and 150 kg ha(-1), with the source of the phosphorus triple superphosphate. Was also used nitrogen and potassium in doses equivalent to 100 and 200 kg ha(-1) and K, respectively. The soil of the experimental area was set to raise the base saturation to 60%. At the beginning of the first rainfall of the rainy season of 2006 was performed with micro fertilization in coverage, in doses equivalent to 6,0; 6,0 and 7,0 kg ha(-1) of Cu, Zn and Mn, respectively. Was The chemical control of weeds. Every month, from August to October 2006, samples were collected in the cane plant. There was initially the number of plants m(2), followed by weighing the material. It was subsequently withdrawn a subsample containing ten plants for weighing. After weighing the material was passed in horsemanship and homogenized, again drew up a sample of approximately 300g, leading them to forced ventilation oven at 65 degrees C, toobtain constant weight. Resulting in the production of natural (MN) and dry matter (DM). In July, we analyzed the levels of Brix% juice in the refractometer Brix. The average values of production of natural (MN), dry matter (DM) and contents of Brix% were subjected to analysis of variance and regression for variables. The accumulation of dry matter and were influenced by fertilization. The contents of Brix% in two varieties did not suffer significant influence of fertilization.

Controle do cupim de montículo (Isoptera: Termitidae) de pastagem com fungos entomopatogênicos

The objective of this study was to evaluate the control of mound-building termites (Isoptera: Termitidae) by entomopathogenic fungi (Metarhizium anisopliae and Beauveria bassiana). We developed two experiments, with two copies of application in three sizes of nests. The first was installed in the Salto Macauba farm and second in the Laboratory of Plant Protection at the State University of Mato Grosso do Sul. The first experiment consisted of five repetitions, each nest an experimental unit, with treatments in a factorial 2 (fungi) x 2 (tests) x 2 (type of spraying) + 1 control, distributed completely at random in the area. The treatments were: 1) control - no implementation, 2) Metarril M103 (M. anisopliae) - 10 g/mound-dusting, 3) Metarril M103 - 10 g/mound - via net, 4) Metarril M103 - 15 g/mound-dusting, 5) Metarril M103 - 15 g/mound - via net, 6) Boveril B102 (B. bassiana) - 10 g/mound - dusting, 7) Boveril B102 - 10 g/mound - via net, 8) Boveril B102 - 15 g/mound-dusting and 9) Boveril B102 - 15 g/mound-via net. The testing of mortality were made spraying of the laboratory with the field measurements performed in compliance with the same separation of the nests. The results suggested that the road dust (dosage of 10 g) of the fungi studied showed higher mortality of nests of small size (53%). B. bassiana (Boveril) (10 g) gave 80% mortality of C. cumulans when applied to nests of small size.

Interferência da Brachiaria Decumbens Stapf. sobre plantas daninhas em sistema de consórcio com o milho

Forage plants cultivated in consortium with crop corn, facilitating the weed control in farming and cattle raising ecosystem, interfering not only in your biological productivity, like in your potential of distribution and infestation in area. This experiment was realized with the aim to evaluate the weed suppress by Brachiaria decumbens in intercropping with corn (Zea mays L.). The even was composed by combination of four forage plant density (0, 10, 15 and 20 kg ha(-1)) and three weed species (Ipomoea grandifolia, Digitaria horizontalis and Cenchrus echinatus), planted intercropping with corn. It was constated that B. decumbens was efficient in weed infestation suppress, being the most effective control for D. horizontalis. The leaf area and dry phytomass of weeds were affected (P<0.05) by forage plant presence, with variation between the density curve of Brachiaria only for weed D. horizontalis and I. grandifolia.

A ação pedagógica sob a perspectiva de Henri Wallon

This research was supported theory as the theory of Henri Wallon which proposes a reflection on the overall development of the child offering subsidies for a acting that values the child in its multiple dimensions. The objective is understood to seek subsidies in theory that can guide the construction of an education in the Children's activites, focused on the development aspects of cognitive, affective and motor of the child. It adopts as methodology the bibliographical revision, the intervention, observation and data collect, using as pedagogic resource playing activities in an institution of Infantile Education. The research noted the possibility of action with the concepts proposed by the Wallonian theory, furthermore, the Children's Fitness, using the recreational activities such as teaching resources boost child development. Therefore, concluded that physical education should include Child in the process of teaching-learning the full development of the child.

Teoria histórico-cultural e suas implicações na atuação do professor de educação física escolar

This article presents a theoretical search and aims to introduce the main categories of historical-cultural theory and discuss its implications for the physical education teacher's work inside the school and also emphasizes this theory and its methodological proposal as an important way to build the scholar physical education in a critical perspective aiming to change the school and the students conscious and personality.

Associação entre estado nutricional e pressão arterial em escolares

The aim of this study was to analyze the association between nutritional status and blood pressure in adolescents from a private school. Were recruited 316 young of both gender with age raging from 11 to 15 years old. Were measured body mass, stature, systolic blood pressure and diastolic blood pressure. The statistic procedures were composed by median, interquartile range, chi-square test and Poisson regression. The prevalence of overweight and high blood pressure was significantly higher in boys (38% and 24%, respectively) when compared to girls (19.3% and 14.4%, respectively). Overweight adolescents presented a higher risk (about 2-fold) to develop high blood pressure. In conclusion, overweight seems to be associate with high blood pressure in adolescents.

A ‘formação do professor’ e seus sentidos em 23 Anos do Bolema: 1985-2007

We present results of research aiming to identify and analyze the meanings of teacher education in papers published over 23 years of Bolema, from 1985 to 2007. Specifically, we analyzed what the authors of the articles understood as teacher education and how they approached it in their projects, research, and interventions. We found that teacher education is characterized: by means of the definition of teacher education, its objectives and functions; from what is expected of the teacher at the end of the education process; from the disciplinary and/or pedagogical contents proposed in courses; from the practical activities proposed; through suggestions of courses and their curricular structures; from reflections on its limitations and possibilities.

Construção de Conceitos Matemáticos na Educação Básica numa Abordagem Peirceana

Peircean semiotic analysis is employed to examine the construction/representation of signs-thinking of 32 early elementary school students regarding the concept of length measurement. The work consisted of developing concepts of standard unit, reading and interpretation of measurement by instruments, so that the mathematical language presented in the concrete materials was being signified and re-signified as a tool for perception and representation of new concepts. The pedagogical triad Feeling-Perceiving, Relating-Concept (F-P/R/C) co-related with the dynamism of the semiosis process, defined by Charles Sanders Peirce (1839-1914) in his semiotic theory on the production of the sign (Object, Representamen and Interpretant), enabled the interpretation and analysis of the students' inferences in the phase of perception (feel, admire), induction (experience), and deduction (concept).

Efeito do aquecimento com corrida sobre a agilidade e a impulsão vertical em jogadores juvenis de futebol

The aim of this study was to evaluate the effect of warm-up on agility (AG) and on vertical jump (VJ) tests in youth soccer players. Sixteen players performed the AG and VJ tests without warm-up (NW) and with warm-up (WW) randomly, within two weeks, at least 48 h interval, during season. The warm-up was performed only a light running during 10 min. The paired t-test identified significant difference (p <0,05) between the NW and WW conditions in the tests of SR and CJ (9,14 +/- 0,28 vs 8,94 +/- 0,30 s e 51,4 +/- 4,2 vs 54,5 +/- 6,4 cm, respectively). The warm-up performed on light intensity running was effective to improve the AG and VJ tests performance in youth soccer players.
