Resumo: Tomato is one of the most demanding agricultural crops in potassium (K), and the correct supply of the nutrient is decisive for the success of the activity. In organic fruit production, potassium fertilization is especially complex. In Brazil, the scenario does not help the organic tomato producer, most certified inputs have low K content and solubility, and, in many cases, low response to fertilization. This study aimed to evaluate the productivity and quality of italian tomato fruits submitted to potassium fertilization with three sources of free use in organic agriculture. The treatments consisted of two certified potassium sulfates (Polivida and Allganic) and an organic residue from the coffee powder industry (coffee pellicle), in doses of 500 and 700 kg ha-1 of K2O, totally at planting or divided into planting plus three coverages. The seedling survival rate, production (number and mass) and quality (rate of hollow and full fruits and total soluble solids) of fruits were evaluated. The results show no statistical difference between treatments for both production and quality (rate of hollow, full and total soluble solids) of the fruits. However, treatments with coffee pellicle required seedling replanting in the first 14 days after transplanting, increasing cultivation costs.

En la producción de frutas orgánicas, la fertilización con potasio es especialmente compleja. En Brasil, el escenario no ayuda al productor de tomate orgánico, la mayoría de los insumos certificados tienen bajo contenido de K y solubilidad y, en muchos casos, baja respuesta a la fertilización. Este estudio tuvo como objetivo evaluar la productividad y calidad de frutos de tomate italianos sometidos a fertilización potásica con tres fuentes de libre uso en agricultura orgánica. Los tratamientos consistieron en dos sulfatos de potasio certificados (Polivida y Allganic) y un residuo orgánico de la industria del café en polvo, en dosis de 500 y 700 kg ha-1 de K2O, totalmente en plantación y dividido en plantación más tres coberturas. Se evaluó la tasa de supervivencia de las plántulas, la producción (número y masa) y la calidad (tasa de frutos huecos y llenos y sólidos solubles totales) de frutos. Los resultados no muestran diferencias estadísticas entre los tratamientos tanto para la producción como para la calidad (tasa de frutos huecos, llenos y sólidos solubles totales) de los frutos. Sin embargo, los tratamientos con película de café requirieron la resiembra de plántulas en los primeros 14 días después del trasplante, aumentando los costos de cultivo.O tomateiro é uma das plantas mais exigentes no elemento potássio (K), sendo o correto fornecimento do nutriente decisivo para o sucesso da atividade. Na produção orgânica do fruto, as adubações potássicas são especialmente complexas. No Brasil, o cenário não ajuda o produtor de tomate orgânico, a maioria dos insumos certificados apresentam baixo teor ou solubilidade de K, e, em muitos casos, baixa resposta à adubação. O presente trabalho teve por objetivo avaliar a produtividade e qualidade de frutos de tomate italiano submetidos a adubação potássica com três fontes de uso liberado na agricultura orgânica. Os tratamentos foram constituídos por dois sulfatos de potássio certificados (Polivida e Allganic) e um resíduo orgânico da indústria de pó de café (película de café), nas doses de 500 e 700 kg ha-1 de K2O, totalmente no plantio ou dividido em plantio mais três coberturas. Foram avaliadas a taxa de sobrevivência das mudas, a produção (número e massa) e a qualidade (taxa de frutos ocos e cheios e sólidos solúveis totais) de frutos. Os resultados mostram ausência de diferença estatística entre os tratamentos tanto para produção como qualidade (taxa de frutos ocos, cheios e sólidos solúveis totais) dos frutos. No entanto, os tratamentos com película de café necessitaram de replantio de mudas nos primeiros 14 dias após o transplantio, elevando os custos de cultivo.Research, Society and Development2021-11-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2216910.33448/rsd-v10i14.22169Research, Society and Development; Vol. 10 No. 14; e484101422169Research, Society and Development; Vol. 10 Núm. 14; e484101422169Research, Society and Development; v. 10 n. 14; e4841014221692525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/22169/19808Copyright (c) 2021 Edmar Guedes; Rodrigo Fernandes Santos; Cristiane Rocha Guedes; Emanuele Possas de Souza; Antonio Ismael Inácio Cardosohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessGuedes, EdmarSantos, Rodrigo FernandesGuedes, Cristiane RochaSouza, Emanuele Possas deCardoso, Antonio Ismael Inácio2021-12-04T11:48:39Zoai:ojs.pkp.sfu.ca:article/22169Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:41:24.281499Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
