Nutrição e produtividade da cultura do milho em sistemas de culturas e fontes de adubação

A utilização de esterco animal na agricultura, aliada ao cultivo de plantas de cobertura, pode conferir sustentabilidade ao sistema agrícola. Com o objetivo de avaliar o efeito de dois sistemas de culturas e de três fontes de nutrientes, na cultura do milho, conduziu-se um experimento, em Latossolo Vermelho, no município de Marechal Cândido Rondon (PR). O delineamento experimental utilizado foi de blocos casualizados, com quatro repetições, e, os tratamentos, dispostos em esquema fatorial 2 x 3, compostos por dois sistemas de culturas (sucessão trigo/milho e consórcio aveia+ervilhaca+nabo/milho) e três fontes de nutrientes (mineral, orgânica e organomineral). em junho de 2006, implantou-se a cultura do trigo e o consórcio de plantas de cobertura. em outubro de 2006, semeou-se milho sob os dois sistemas. As adubações orgânica e organomineral consistiram na aplicação de dejetos de suínos, unicamente, e combinada com fertilizante mineral, respectivamente. O consórcio de aveia preta, ervilhaca peluda e nabo forrageiro mostrou-se capaz de fornecer a quantidade adequada de biomassa, concretizando sua viabilidade para produção de cobertura vegetal ao solo, durante o inverno. O cultivo de milho em sucessão ao trigo proporcionou a maior absorção de N e K e a maior produtividade. A adubação mineral proporcionou maior absorção de N e maior produtividade de milho, em comparação com as adubações orgânica e organomineral com dejetos de suínos.

MS2SV: Tradução de modelos em Simulink para VHDL-AMS

This paper presents a methodology and a tool for projects involving analogue and digital signals. A sub-systems group was developed to translation a Matlab/Simulink model in the correspondent structural model described in VHDL-AMS. The developed translation tool, named of MS(2)SV, can reads a file containing a Simulink model translating it in the correspondent VHDL-AMS structural code. The tool also creates the directories structure and necessary files to simulate the model translated in System Vision environment. Three models of D/A converters available commercially that use R-2R ladder network were studied. This work considers some of challenges set by the electronic industry for the further development of simulation methodologies and tools in the field of mixed-signal technology. Although the objective of the studies has been the D/A converter, the developed methodology has potentiality to be extended to consider control systems and mechatronic systems.

Estoque de carbono orgânico no solo afetado por adubação orgânica e sistemas de culturas no Sul do Brasil

Organic carbon is a major component of soil organic matter and its stock is influenced by the management system adopted. This study aimed to examine the effects of cropping systems and nutrient sources (mineral and organic) on the concentrations and storage of soil organic carbon in no-tillage system. The experiment was carried out in Mercedes, Parana, Brazil, in an Nitossolo Vermelho (Alfisol) from October 2007 to September 2009. The treatments consisted of four crop succession systems: (1) soybean/wheat/corn/wheat; (2) soybean/black oat/corn/black oat, (3) soybean/radish/corn/radish and (4) soybean/common vetch/corn/common vetch and by two sources of nutrients (mineral and organic), arranged in a to split plot randomized block design with four replications. Soil samples were collected in layers of 0.0-0.05, 0.05-0.10, 0.10-0.20 and 0.20 to 0.40 m deep in the first and the second years of cultivation. Different cropping systems does not affect the content and the stock of soil organic carbon in the first two years of adoption of the systems. The organic fertilization with manure increased soil organic carbon stock, with an annual contribution of C, layer 0.0 to 0.20 m, 1.15 Mg ha(-1) yr(-1). Cropping systems fertilized with mineral fertilizers provide the greatest losses of soil organic carbon, resulting in negative balance of C in soil.

AVALIACAO DO EFEITO DO VENENO DE APIS MELLIFERA EM CULTURAS DE E. COLI, S. TYPHIMURIUM E Y. ENTEROCOLITICA TRATADAS COM BLEOMICINA

Apis mellifera bee venom (Africanized honey bee) was tested for the ability to protect against the lethal effect of bleomycin, an antibiotic and antineoplastic agent. Since the radioprotective effect of the venom has been observed on the other biological systems, in the present study the venom was applied to cultures of enterobacteria treated with bleomycin, a radiomimetic agent. The venom did not act as a protective agent against bleomycin in E. coli, S. typhimurium or Y. enterocolitica.

Estudo preliminar de uma metodologia baseada no conceito de graus-dia, para previsão das fases fenológicas de culturas agrícolas

This work develops a methodology (using the degree-days concept and linear regression), to forecast the duration of phenological phases in crops. An experiment was conducted in the greenhouse with three cultivars of cowpea (Vigna unguiculata (L.) Walp.), cv. Califórnia-781, Tvx 5058-09C and IT 81D-1032. The methodology was based on the relative thermal efficiency rate, determined for each species or cv. The results show that the proposed methodology may be a good alternative in works involving crops, especially because it does not require the repetition of the experiments.

Comportamento do cafeeiro apoatã em consórcio com culturas anuais

This study was conducted in Adamantina, region of Alta Paulista, São Paulo State, Brazil, from 1989 to 1993. Yield of Apoatã coffee (Coffea canephora Pierre ex Froehner) was evaluated during four years of intercropping with five plant species: IAC 20 - cotton (Gossypium hirsutum L.); cv. Tatu - peanut (Arachis hypogaea L.); IAC 165 - rice (Oryza sativa L.); cv. Guarani - castor bean (Ricinus communis L.) and IAC 100-B - corn (Zea mays L.). The crops were seeded 50 cm apart from coffee canopy. The treatments were arranged in randomized complete block design with five replications. Yield was significantly decreased when coffee was intercropped with castor bean, corn, cotton and peanut, but height and diameter of orthotropic branches were not affected. Linear correlation analysis showed that coffee yield was inversely correlated with the dry biomass of the intercrops.

Exposição de culturas de fibroblastos de pterígios primários e recidivados à mitomicina c e ao 5-fluorouracil

Purpose: To evaluate the proliferation of the fibroblasts from primary and recurrent pterygium in culture of cells, after the exposure to mitomycin C and to 5-fluorouracil. Methods: Cultures of fibroblasts from primary and recurrent pterygiuns had been carried through. The cells of the third passage were exposed to mitomycin C 0.4% during 3 minutes and to 5-fluorouracil 25mg/ml that was kept in the nutritional medium. After 3, 6, 12 and 18 days of the exposure, cell countings were made in hemocytometer, in triplicate, with a control not treated with the drugs for each day. The data were submitted to statistical analysis.Results: Mitomicyn C had homogeneous behavior in the primary and recurrent groups, which inhibited the cellular proliferation since the first counting day. However, with 5-fluorouracil, the proliferation inhibition was verified only after the third day of evaluation (in the second counting day) in the recurrent group, and since the first counting day in the primary group. At the end of the experimental period, 5-fluorouracil and mitomycin C were equally efficient in the inhibition of the fibroblasts from primary and recurrent pterygium proliferation. In the controls not exposed, the cell's numbers were increasing during the experimental time.Conclusion: Mitomycin and 5-fluorouracil are equally able to inhibit fibroblasts proliferation from primary and recurrent pterygium Tenon's capsule in cell culture.
