Resumo: | The objective of this work was to study the quality and variability, from a statistical process control point of view, of the deposition on coffee crop leaves and the loss to the soil promoted by pulverization with an air-blast sprayer using different application volumes and droplet sizes. The experiment was carried out in Arabica coffee crop using the 2x2 factorial design and eight replicates, with the factors being the droplet sizes generated by two types of nozzles (hollow cone - ATR - which produced fine droplets, and hollow cone with air induction - TVI - which produced extremely large drops) and spray application volumes (200 and 500 L ha-1). Brilliant Blue tracer was used to quantify by spectrophotometry the spray deposits on the leaves of the top and bottom halves of the plant and on the ground targets. The statistical quality of sprays was evaluated using statistical process control. Control charts show that there is no detectable patterns of non-randomness within treatments, ensuring the good quality of the pulverizations in the coffee crop. The spraying using the volume of 500 L ha-1 provides flexibility in the choice of hydraulic nozzle, keeping quality and low variability of deposition in the coffee leaves. |

O experimento foi conduzido em café arábica no esquema fatorial 2x2, com oito repetições, sendo os fatores tamanhos de gotas (jato cônico vazio – ATR - que produziu gotas finas; e jato cônico vazio com indução de ar – TVI – que produziu gotas extremamente grossas) e volumes de calda (200 e 500 L ha-1). Utilizou-se o traçador Azul Brilhante para quantificar por espectrofotometria os depósitos de calda nas folhas da parte superior e inferior e em lâminas de vidro localizadas no solo. Avaliou-se a qualidade estatística das pulverizações, utilizando-se controle estatístico de processo. As cartas de controle mostram que não se detectam padrões de não aleatoriedade dentro dos tratamentos, assegurando a boa qualidade das aplicações realizadas na cultura do café. A aplicação utilizando o volume de 500 L ha-1 proporciona flexibilidade na escolha da ponta hidráulica, mantendo qualidade e baixa variabilidade de deposição nas folhas do cafeeiro.Editora UFLA2016-03-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/zipapplication/ziphttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/951Coffee Science - ISSN 1984-3909; Vol. 11 No. 1 (2016); 11 - 21Coffee Science; Vol. 11 Núm. 1 (2016); 11 - 21Coffee Science; v. 11 n. 1 (2016); 11 - 211984-3909reponame:Coffee Science (Online)instname:Universidade Federal de Lavras (UFLA)instacron:UFLAporhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/951/pdf_2https://coffeescience.ufla.br/index.php/Coffeescience/article/view/951/1481https://coffeescience.ufla.br/index.php/Coffeescience/article/view/951/1482Copyright (c) 2016 Coffee Science - ISSN 1984-3909https://creativecommons.org/info:eu-repo/semantics/openAccessRibeiro da Silva, João EduardoArantes Rodrigues da Cunha, João PauloSiqueira Schroden Nomelini, Quintiliano2016-03-23T02:36:31Zoai:coffeescience.ufla.br:article/951Revistahttps://coffeescience.ufla.br/index.php/CoffeesciencePUBhttps://coffeescience.ufla.br/index.php/Coffeescience/oaicoffeescience@dag.ufla.br||coffeescience@dag.ufla.br|| alvaro-cozadi@hotmail.com1984-39091809-6875opendoar:2024-05-21T19:53:53.643422Coffee Science (Online) - Universidade Federal de Lavras (UFLA)true |
