Resumo: Phosphorus (P) is essential to increase tuber yield and nutritional quality of potato tubers. However, it is unclear whether the influence of P fertilization on quality of tubers produced can vary depending on the cultivar and P availability in soil. This study evaluated the effect of P fertilization on the quality and nutritional composition of marketable tubers of potato cultivars. Experiments in soils with low, medium and high P availability were conducted in a randomized block design, with four replications. Treatments consisted of a 2×5 factorial arrangement of two potato cultivars (Agata and Mondial) and five P2O5 rates (0, 125, 250, 500, and 1,000 kg ha–1). Phosphorus fertilization increased the contents of P and starch, the size and yield of marketable tubers, with more expressive response to higher P rates in the soils with low and medium P availability. The Mondial cultivar had the highest yield, due to a greater tuber weight and greater increases in this characteristic in response to P fertilization. The Mondial cultivar produced tubers with firmer pulp, with higher dry matter percentage and higher contents of Ca, Cu, and Zn than Agata. In the soil with low P availability, P fertilization reduced Zn content, but, in general, had little influence on the nutritional composition of potato tubers.

Porém não se sabe se a influência da adubação fosfatada na qualidade dos tubérculos produzidos pode variar em função da cultivar e da disponibilidade de P no solo. O objetivo deste trabalho foi avaliar o efeito da adubação fosfatada sobre a qualidade e composição nutricional dos tubérculos comercializáveis de cultivares de batata. Foram conduzidos experimentos em solos com baixa, média e alta disponibilidade de P, utilizando delineamento de blocos ao acaso, no esquema fatorial 2 × 5, com quatro repetições. Os tratamentos foram constituídos por duas cultivares de batata (Agata e Mondial) e cinco doses de P2O5 (0, 125, 250, 500 e 1.000 kg ha–1). A adubação fosfatada aumentou o teor de P e de amido, o tamanho e a produtividade de tubérculos comercializáveis, com resposta mais expressiva às maiores doses nos solos com baixa e média disponibilidade de P. A cultivar Mondial foi mais produtiva, por apresentar maior massa média de tubérculos e maiores aumentos nessa característica em resposta a adubação fosfatada. A cultivar Mondial produziu tubérculos com polpa mais firme, com maior percentagem de matéria seca e com maiores teores de Ca, Cu e Zn do que a Agata. Em solo com baixo P disponível, a adubação fosfatada reduziu o teor de Zn mas, de maneira geral, teve pouca influência na composição nutricional dos tubérculos de batata.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Universidade Estadual Paulista, Centro de Raízes e Amidos Tropicais, Faculdade de Ciências Agronômicas de BotucatuUniversidade Estadual Paulista, Departamento de Produção e Melhoramento Vegetal, Faculdade de Ciências Agronômicas de BotucatuUniversidade Estadual Paulista, Departamento de Horticultura, Faculdade de Ciências Agronômicas de BotucatuFAPESP: 2010/04987-6FAPESP: 2012/12128-9Instituto Agronômico de CampinasUniversidade Estadual Paulista (Unesp)Fernandes, Adalton Mazetti [UNESP]Soratto, Rogério Peres [UNESP]Moreno, Letícia de Aguila [UNESP]Evangelista, Regina Marta [UNESP]2015-08-26T19:22:34Z2015-08-26T19:22:34Z2015-03-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article102-109application/pdfapplication/pdfhttp://www.scielo.br/scielo.php?script=sci_arttext&pid=S0006-87052015000100102&lng=pt&nrm=iso&tlng=enBragantia, v. 74, n. 1, p. 102-109, 2015.0006-8705http://hdl.handle.net/11449/12749710.1590/1678-4499.0330S0006-87052015000100102S0006-87052015000100102-en.pdfS0006-87052015000100102-pt.pdf820133636746913066421736688314070000-0002-6745-0175SciELOreponame:Repositório Institucional da UNESPinstname:Universidade Estadual Paulista (UNESP)instacron:UNESPporBragantia0,555info:eu-repo/semantics/openAccess2024-04-30T15:58:32Zoai:repositorio.unesp.br:11449/127497Repositório InstitucionalPUBhttp://repositorio.unesp.br/oai/requestopendoar:29462024-08-05T21:41:34.715546Repositório Institucional da UNESP - Universidade Estadual Paulista (UNESP)false
