Resumo: | Phosphate fertilization is indispensable for carrot cultivation, as it contributes to plant development, formation of marketable roots and higher yields. In this context, the objective of this study was to evaluate the production and nutritional efficiency of carrot cultivars under phosphate fertilization. The experiments were carried out from July to November 2016 and from June to October 2017, at the Rafael Fernandes experimental farm, District of Alagoinha, Mossoró, RN, Brazil. The experimental design was in randomized blocks, in a 4×4 factorial scheme with 4 replicates. The treatments consisted of the combination of carrot cultivars (Brasília, Planalto, Suprema and Nativa) with phosphorus (P) doses (0, 90, 180 and 270 kg ha-1 P2O5). The characteristics analyzed were: P content in the diagnostic leaf, plant dry matter, plant height, marketable and total yields, and the classification of cultivars for efficiency and response to phosphate fertilization. The increments promoted by phosphate fertilization were 64% in plant height, 444% in dry matter and 284% in marketable yield. The maximum marketable yield was obtained with doses from 186.8 to 243.5 kg ha-1, depending on the cultivar. The Native cultivar was classified as more efficient in the use of P. |

Neste contexto, o objetivo do trabalho foi avaliar a produção e eficiência nutricional de cultivares de cenoura sob adubação fosfatada. Os experimentos foram realizados no período de julho a novembro de 2016 e junho a outubro de 2017, na fazenda experimental Rafael Fernandes, distrito de Alagoinha, Mossoró, RN. O delineamento experimental foi em blocos ao acaso, em esquema fatorial 4×4 com 4 repetições. Os tratamentos consistiram da combinação das cultivares de cenoura (Brasília, Planalto, Suprema e Nativa) com doses de fósforo (0, 90,180 e 270 kg ha-1 P2O5). As características analisadas foram: Teor de P na folha diagnóstica, matéria seca da planta, altura de planta, produtividades comercial e total e a classificação das cultivares quanto à eficiência e resposta a adubação fosfatada. A adubação fosfatada proporcionou aumento na matéria seca e altura das plantas, e as doses que maximizaram as produtividades comerciais foram de 186,8; 208,0; 217,6 e 243,5 kg ha-1 de P2O5 para as cultivares Nativa, Suprema, Planalto e Brasília, respectivamente. A cultivar Nativa foi eficiente e responsiva a adubação fosfatada, enquanto que, a Suprema apenas responsiva e a Brasília e Planalto não eficientes e não responsivaEDUFU2021-12-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/5409510.14393/BJ-v37n0a2021-54095Bioscience Journal ; Vol. 37 (2021): Continuous Publication; e37085Bioscience Journal ; v. 37 (2021): Continuous Publication; e370851981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/54095/32966Brazil; Contemporary Copyright (c) 2021 Priscila Maylana Modesto de Jesus, Leilson Costa Grangeiro, Valdívia de Fatima Lima de Sousa, Gerlani Alves da Silva, Luiz Ricardo Rebouças da Silva, Gardênia Silvana de Oliveira Rodrigueshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccess Modesto de Jesus, Priscila MaylanaGrangeiro, Leilson CostaLima de Sousa, Valdívia de Fatima Alves da Silva, Gerlani Rebouças da Silva, Luiz Ricardo de Oliveira Rodrigues, Gardênia Silvana 2022-05-25T13:33:06Zoai:ojs.www.seer.ufu.br:article/54095Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-05-25T13:33:06Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false |
