Coeficientes de Cultura da Chicória (cichorium Endivia L.)

O conhecimento do coeficiente de cultura (Kc) permite a estimativa das necessidades hídricas de uma cultura, sendo fundamental para o manejo da irrigação. Nesta pesquisa, conduzida na área experimental do Departamento de Recursos Naturais da Faculdade de Ciências Agronômicas – FCA/UNESP, Campus de Botucatu, utilizou-se, para medida da evapotranspiração da cultura (ETc), 4 evapotranspirômetros de nível freático constante. Desses, 2 foram cobertos com plástico transparente rente ao solo, a fim de se evitar a evaporação. A evapotranspiração de referência (ETo) foi estimada pelo método de Penman-Monteith, sendo o coeficiente de cultura da chicória (Cichorium endivia L.) dado pela relação: , em suas diversas fases de desenvolvimento. Os valores de (Kc) obtidos evidenciaram um comportamento crescente durante todo o período vegetativo, com a influência da cobertura plástica na fase inicial quando a evaporação do solo representa uma fração considerável da evapotranspiração da cultura.

The impact of the law 10,267/2001 in the brazilian rural registration

The publication of the Law 10,267 of 08/28/2001 changed the paradigm of rural registration in Brazil, because this law known as the Law of Georeferencing has created the National Registration of Rural Property, that unifies in a common basis different registrations present in several government agencies, such as the National Institute for Colonization and Agrarian Reform (INCRA), the Secretariat of Federal Revenue, the Brazilian Institute of Environment and Natural Resources, and the National Indian Foundation. Also, this new registration system has a graphical component which has not existed until such date, where the boundaries of rural property are georeferenced to the Brazilian Geodetic System. This new paradigm has resulted in a standardization of the survey and its representation of rural properties according to the Technical Standard for Georeferencing of Rural Properties, published by INCRA in compliance with the new legislation. Due to the georeferencing, the creation of a public GIS of free access on the Internet was possible. Among the difficulties found it may be observed the great Brazilian territory, the need for specialized professionals, and especially the certification process that INCRA has to perform for each georeferenced property. It is hoped that this last difficulty is solved with the implementation of the Land Management System that will allow automated and online certification, making the process more transparent, agile and fast.

Formação de mudas de alface em bandejas preenchidas com diferentes substratos

This study was conducted in the Department of Horticulture and Experimentation at the University Jose do Rosario Vellano (UNIFENAS) in Alfenas-MG, Brasil in order to evaluate the formation of lettuce seedlings in trays filled with different substrates. The materials used to compose the substrates were pig bed base with wood shavings (M), pig bed with base coffee straw (C), earthworm humus (H) and commercial substrates Nutriorg (R) and Plantmax (R) The use of these pure substrates and various mixtures permitted the formation of 18 substrates that constituted the treatments. The experimental design was a completely randomized design with three replications. The lettuce seedlings were formed with the lettuce cultivar Regina. The seeds were sown in trays with 128 cells filled with the substrates under study. Each experimental unit was compost of 64 cells. The conduct of the experiment was within a protective structure of 85 m 2, model chapel with transparent plastic cover 100 microns thickness, additives against ultraviolet rays. After 30 days of sowing, ten seedlings were harvested randomly within each experimental unit for evaluating the number of leaves and the plant height. It was also evaluated the fresh and dry mass of aerial part and fresh and dry mass of root. It was concluded that the substrate T1 - M met the best features for the formation of lettuce seedlings in trays of 128 cells.

Viabilidade e longevidade de sementes de tabebuia aurea benth. & hook. submetidas a diferentes métodos de armazenamento

Seeds Tabebuia aurea (syn. Handroanthus aureus Mattos), The seeds of Tabebuia aurea (syn. Handroanthus Mattos aureus), have low metabolic rates, which favors their storage conditions and freezing temperatures when stored at room temperature, there is a progressive decline in viability. Therefore, this study aims to determine the viability and longevity of seeds of Tabebuia aurea subjected to different storage methods. There were used 6100 seeds. In 2400 seeds were stored refrigerator, which in 1200 placed in transparent plastic bag and 1200 in Kraft paper bags. 3600 Other seeds were placed in room temperature and 1200 seeds in clear plastic bag, 1200 in Kraft paper bags and tray open in 1200. For each treatment, four replicates of 25 seeds for 12 months, with design was completely randomized. The average germination, normal seedlings and speed germination index were transformed into (x+1)(-1/2). The data were submitted to ANOVA and means compared by Tukey test at 5%. Also regressions polynomials were modeled for the variables study in function of the periods of storage of the seeds. The seeds stored in the refrigerator at 13 C maintained a high germination rate and normal seedling germination rate during the 360 days of evaluation. The method suitable for the seed storage of Tabebuia aurea is in the refrigerator at 13 degrees C, both in plastic and paper.

Influência de protetores físicos coloridos nas trocas gasosas de Canafístula (Peltophorum dubium (Spreng.) Taub.)

The aim of this experiment was to study the influence of transparent, blue and red tree shelters on gas exchanges of canafístula’s (Peltophorum dubium (Spreng.) Taub.) seedlings. This study was carried out in Department of Botany, Institute of Biosciences, U ESP, Botucatu, São Paulo State, Brazil. The experiment design was randomized blocks, with 5 replications, each one containing 6 units of each treatment (nonsheltered, transparent tree shelters, blue tree shelters and red tree shelters). The evaluations of gas exchanges were made through an infrared gas analyzer. It follows that the tree shelters use may limit the photosynthesis, increase the transpiration and stomatal opening, besides reducing the water use efficiency. The colored tree shelters use created unfavorable conditions for the development, reducing the photosynthesis, because they reflected the blue and red wavelengths, allowing only the passage of the other components of the white light or of the photosynthetically active radiation

Orientação sexual nas aulas de educação física escolar

Sexual Orientation is present in the school setting, due to human relationships among all belonging to this area. Being a cross-cutting theme, this theme pervades the Physical Education and allows discussions related to the gender, body and media, respect for diversity, disease prevention and other topics that the contents of body culture allow to deal. With observation and participation in the school context, through a stage of more than a year, we realized the need to address the issue of sexual orientation with students. In addition, there is a dearth of articles dealing with this topic, a factor that complicates and limits the search fields of material for the teacher preparing lessons and address the issue. Thus, this study aims to develop classes to subsidize the practice of teachers of physical education in relation to Sexual Orientation. The preparation of activities was carried out from a bibliographic review and experiences of the researchers, presenting new possibilities to teacher to treat this subject in classes of that discipline. The topics covered are intended to demystify some pre-concepts related to gender in bodily practices that are socially constructed. Also, presented a way to address STDs and teenage pregnancy, topics not found in academic magazines of the area used in this study. Treating Sexual Orientation in Physical Education classes may seem at first a tricky and of difficult data collection. The teacher must seek this knowledge so that it can address the issue with students in a transparent and really effective not being only informative classes meaningless or decontextualized thoughts
