Resumo: | Nowadays there is a trend of become the operational of agrochemicals spray faster. Then, it may cause a direct impact on the spray quality of a given product, influencing even directly the effectiveness of it control. The present study investigated the feature of application as reduced spray rates in combination with different spray nozzles in two wheat cultivars. Field experiment was conducted in the winter of 2011 at Institute Phytus experimental field, on Itaara, central region of Rio Grande do Sul. It was test rates of 180, 140, 100 and 60 L/ha applied with the nozzles XR 11001, TT 11001 and TT 110015 on Fundacep 52 and Quartzo wheat cultivars, on three times: during the stem elongation, in head emission and in full flowering. For collection of drops of dye was used application on Contact paper cards, which were placed in exactly the same position and with the same format that the leaves if desired look. In each application was performed to characterize the quality as this: volume median diameter (VMD), SPAN (RA), number of droplets per square centimeters and percentage of coverage. Common to both cultivars, the DMV was conditioned only by the nozzles, being always smaller for XR 11001, and AR did not vary in any situation. The interaction between spray rates and spray nozzles was more decisive in droplet deposition on the cultivar Fundacep 52 than cultivar Quartzo, and on number of droplet per square centimeters than percentage of coverage. The nozzle XR 11001 tended to result in the greatest number of droplets per square centimeter, while the TT 11001 tended to generate the highest percentage of coverage. Reductions in spray rate normally produce more regular decreases in deposits when were used the TT nozzles regarding XR nozzle. |

Foi conduzido experimento de campo no inverno de 2011 em área experimental do Instituto Phytus, município de Itaara, região central do Rio Grande do Sul, testando as taxas de 180, 140, 100 e 60 L/ha aplicadas com as pontas XR 11001, TT 11001 e TT 110015 sobre as cultivares Fundacep 52 e Quartzo em três momentos. Para coleta das gotas foi utilizada aplicação de corante sobre cartões de papel Contact, os quais foram alocados exatamente na mesma posição e com mesmo formato das folhas que se desejou analisar. Em cada aplicação foram avaliados: área foliar, diâmetro mediano volumétrico (DMV), amplitude relativa (AR), número de gotas/cm2 e percentual de cobertura. O DMV foi condicionado apenas pelas pontas, sendo sempre menor para XR 11001, e a AR não apresentou variação em nenhuma situação. A interação entre taxas de aplicação e pontas de pulverização foi mais determinante na deposição de gotas sobre a cultivar Fundacep 52, em relação a cultivar Quartzo, e sobre número de gotas/cm2, comparativamente ao percentual de cobertura. A ponta XR 11001 tendeu a originar os maiores número de gotas/cm2, enquanto que a ponta XR 11001 tendeu a gerar os maiores percentuais de cobertura. Reduções na taxa de aplicação tenderam a gerar decréscimos mais regulares nos depósitos provenientes das pontas TT do que da ponta XR.Coordenação de Aperfeiçoamento de Pessoal de Nível Superiorapplication/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em Engenharia AgrícolaUFSMBREngenharia AgrícolaTecnologia de aplicaçãoEspectro de gotasDeposição de gotasPercentual de coberturaSpray techDroplet sizeDroplet depositionCoverage percentageCNPQ::CIENCIAS AGRARIAS::ENGENHARIA AGRICOLAQualidade da aplicação em trigo conforme reduções da taxa aplicada em associação com diferentes pontas de pulverizaçãoSpray quality according reductions on spray rate combined with different spray nozzles in wheatinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisBalardin, Ricardo Silveirohttp://lattes.cnpq.br/6547445501940321Costa, Ivan Francisco Dressler dahttp://lattes.cnpq.br/6426393869748708Madalosso, Marcelo Gripahttp://lattes.cnpq.br/2188468950480104http://lattes.cnpq.br/7586734005498718Cezar, Heraldo Skrebsky500300000008400500300500500db30a6fa-b8fd-467f-8b97-06372e631430c04a7890-3379-4e95-ba48-8083abee9f09c829a1ba-7182-4747-8ba2-ecf7c08a2b889bfb5ec1-9ca3-4384-a208-75390b709b81info:eu-repo/semantics/openAccessreponame:Manancial - Repositório Digital da UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALCEZAR, HERALDO SKREBSKY.pdfapplication/pdf2542396http://repositorio.ufsm.br/bitstream/1/7568/1/CEZAR%2c%20HERALDO%20SKREBSKY.pdfee39100274821eb896d0f3a1681314a3MD51TEXTCEZAR, HERALDO SKREBSKY.pdf.txtCEZAR, HERALDO SKREBSKY.pdf.txtExtracted texttext/plain258966http://repositorio.ufsm.br/bitstream/1/7568/2/CEZAR%2c%20HERALDO%20SKREBSKY.pdf.txt816f8a5a6798226cd6a4ed3d6c749e5cMD52THUMBNAILCEZAR, HERALDO SKREBSKY.pdf.jpgCEZAR, HERALDO SKREBSKY.pdf.jpgIM Thumbnailimage/jpeg4899http://repositorio.ufsm.br/bitstream/1/7568/3/CEZAR%2c%20HERALDO%20SKREBSKY.pdf.jpg1a73282b3c639b7c9fe37e85e541acdeMD531/75682022-08-15 10:09:22.849oai:repositorio.ufsm.br:1/7568Repositório Institucionalhttp://repositorio.ufsm.br/PUBhttp://repositorio.ufsm.br/oai/requestopendoar:39132022-08-15T13:09:22Manancial - Repositório Digital da UFSM - Universidade Federal de Santa Maria (UFSM)false |
