Resumo: The objective of this study was to evaluate the effect of nitrogen sources and rates on the physicochemical characteristics and yield of tomato plants. Forty hybrids were cultivated at 100 and 400 kg ha-1 of N, combined with four sources (urea, ammonium sulfate, ammonium nitrate and calcium), plus a treatment without N application in a randomized complete block design four replicates. Size, stem diameter, number of leaves, SPAD (Soil Plant Analysis Development), leaf nitrogen, number of fruits / plants, fruit firmness, bark thickness and average fruit size, ° BRIX, pH, calcium, potassium and sodium in fruits. There was an increase in SPAD index, Brix and longitudinal diameter of fruits as a function of the N dose. The use of ammonium nitrate and calcium provided stronger fruits. Urea and ammonium nitrate provided the highest pH value in tomato fruits. The application of the 100 kg ha-1 dose of N resulted in the highest potassium content in fruits. The highest productivity was obtained with the application of sources containing ammonium and the lowest in the control treatment. Sources and doses of nitrogen fertilizers influenced growth, productivity and parameters related to tomato quality.

Foi cultivado o híbrido Forty com doses de 100 e 400 kg ha-1 de N, combinadas com quatro fontes (ureia, sulfato de amônio, nitrato de amônio e de cálcio), mais um tratamento sem aplicação de N em delineamento em blocos casualizados com quatro repetições. Avaliou-se altura, diâmetro do caule, número de folhas, SPAD (Soil Plant Analysis Development), nitrogênio na folha, número de frutos/plantas, firmeza do fruto, espessura da casca e tamanho médio dos frutos, °BRIX, pH, cálcio, potássio e sódio nos frutos. Houve incremento do índice SPAD, ºBrix e diâmetro longitudinal dos frutos em função da dose de N. A utilização do nitrato de amônio e de cálcio proporcionou frutos mais firmes. A ureia e o nitrato de amônio propiciaram o maior valor de pH em frutos de tomate. A aplicação da dose de 100 kg ha-1 de N acarretou o maior teor de potássio nos frutos. A maior produtividade foi obtida com a aplicação de fontes que continham amônio e a menor no tratamento controle. As fontes e as doses de fertilizantes nitrogenados influenciaram o crescimento, produtividade e os parâmetros relacionados à qualidade do tomate.  EDUFU2020-05-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/4195510.14393/BJ-v36n4a2020-41955Bioscience Journal ; Vol. 36 No. 4 (2020): July/Aug.; 1274-1282Bioscience Journal ; v. 36 n. 4 (2020): julho/agosto; 1274-12821981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/41955/28965Brazil; Contemporary Copyright (c) 2020 Natália Silva Assunção, Natalia Oliveira Silva, Flávio Lemes Fernandes, Leonardo Angelo de Aquino, Maria Elisa de Sena Fernandeshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessAssunção, Natália Silva Silva, Natalia Oliveira Fernandes, Flávio Lemes Aquino, Leonardo Angelo de Fernandes, Maria Elisa de Sena 2022-06-14T13:23:25Zoai:ojs.www.seer.ufu.br:article/41955Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-06-14T13:23:25Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false
