Resumo: | The objective of this study was to evaluate the assimilated contents of mineral elements, yield characteristics and fruit quality of ‘Goldex’ yellow melon fertigated with different doses of nitrogen (N) and potassium (K) in two years of cultivation in the region of Apodi Plateau-CE. The design was randomized blocks in a 4x3 factorial scheme with four N doses (0%, 50%, 100%, 150% of the recommended dose) and three K doses (0%, 100%, 150% of the recommended dose). In the shoots of the melon plant, the highest levels of N (N Fert.) and K (K Fert.) fertilization promoted an increase in the assimilated N content up to 48 DAT and a reduction in the assimilated K content at the end of the cycle (62 DAT). The maximum shoot dry mass production was 3.23 t ha-1 with a fertilization of 150 and 100 kg ha-1 of N and K, respectively. The average marketable fruit yield obtained in the two years of cultivation was 34.68 t ha-1, reaching a maximum value of 40.28 t ha-1 under 150 kg ha-1 N and K fertilization. Total soluble solids increased as a function of the increase in N Fert. and K Fert., with a maximum value of 8.07 °Brix. The models indicated that the K Fert. factor was decisive in the increase of this variable. In future studies it is necessary to increase the concentrations of the two factors in order to optimize the maximum viability of yield and °Brix. |

O delineamento foi em blocos ao acaso em esquema fatorial 4x3 com quatro doses de nitrogênio (0%, 50%, 100%, 150% da dose recomendada) e três doses de potássio (0%, 100%, 150% da dose recomendada). Na parte aérea do melão, os maiores níveis de adubação nitrogenada (N Fert.) e potássica (K Fert.) proporcionaram um aumento do teor assimilado de nitrogênio (N) até 48 DAT e redução do teor assimilado de potássio (K) no final do ciclo (62 DAT). A produção máxima de massa seca da parte foi de 3,23 t ha-1 com uma adubação de 150 e 100 kg ha-1 de N e K, respectivamente. A produtividade de fruto comercial média obtida nos dois anos de cultivo foi 34,68 t ha-1 chegando a um valor máximo de 40,28 t ha-1 em adubação de 150 kg ha-1 de N e K. O teor de sólidos solúveis totais aumentou em função do aumento da N Fert. e K Fert. apresentando máximo valor 8,07 °Brix. Os modelos indicaram que o fator K Fert. foi determinante no aumento desta variável. Em futuros estudos é necessário aumentar as concentrações dos dois fatores a fim de otimizar a viabilidade máxima da produtividade e °Brix.Universidade Federal Rural do Semi-Árido2022-04-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/988910.1590/1983-21252022v35n208rcREVISTA CAATINGA; Vol. 35 No. 2 (2022); 320-330Revista Caatinga; v. 35 n. 2 (2022); 320-3301983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/9889/10902Copyright (c) 2022 Revista Caatingainfo:eu-repo/semantics/openAccessMoreira, Luis Clenio JárioSilva, Lucivânio Domingos daNascimento, Beatriz Maia doSilva, André Jeffeson Barros daTeixeira, Adunias dos SantosOliveira, Marcio Regys Rabelo de2023-07-03T17:41:55Zoai:ojs.periodicos.ufersa.edu.br:article/9889Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:46:53.871101Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
