Resumo: | Among the possibilities of obtaining high grain yields in a crop, as well as costs reduction, stands out the identification of genotypes with greater efficiency in the absorption and utilization of nutrients. This study aimed to evaluate agronomic traits (plant height, stem diameter and number of leaves), nutrient contents (N, P, K, Ca, Mg, S and B) and grain yield of sunflower genotypes. The experimental design was a randomized blocks design, with 8 genotypes (M734, HELIO 358, Embrapa 122, HLE 23, MG 341, BRS G37, BRS G41, V90631) and four replications. All genotypes presented plant height, stem diameter and number of leaves within the standards established for hybrids and commercial varieties. Foliar concentrations of N, P, Mg, S and B were not influenced by the sunflower genotypes. The foliar contents of K and Ca were distinct among the sunflower genotypes, with the highest levels observed in HELIO 358 and MG341, respectively. The highest grain yields were obtained with BRS G37, HLE 23, M734 and HELIO 358. There was a positive correlation between morphological characters and nutrient contents in the V90631 and Embrapa 122 cultivars, and between nutrient contents and grain yield in the M734 cultivar. |

Este trabalho objetivou avaliar caracteres agronômicos (altura de plantas, diâmetro de caule e número de folhas), teores de nutrientes (N, P, K, Ca, Mg, S e B) e rendimento de grãos de genótipos de girassol. O delineamento experimental utilizado foi o de blocos casualizados, com 8 genótipos (M734, HELIO 358, Embrapa 122, HLE 23, MG 341, BRS G37, BRS G41, V90631) e quatro repetições. Todos os genótipos apresentaram altura de plantas, diâmetro de caule e número de folhas dentro dos padrões estabelecidos para híbridos e variedades comerciais. Os teores foliares de N, P, Mg, S e B não foram influenciados pelos genótipos de girassol. Os teores foliares de K e Ca foram distintos entre os genótipos de girassol, sendo os maiores teores encontrados em HELIO 358 e MG341, respectivamente. Os maiores rendimentos de grãos foram obtidos com BRS G37, HLE 23, M734 e HELIO 358. Houve correlação positiva entre os caracteres morfológicos e teores de nutrientes, nas cultivares V90631 e Embrapa 122, e entre os teores de nutrientes e rendimento de grãos, na cultivar M734.Escola de Agronomia - Universidade Federal de Goiás2014-12-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.ufg.br/pat/article/view/27269Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 44, n. 4, Oct./Dec. 2014; 434-442Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 44, n. 4, out./dez. 2014; 434-442Pesquisa Agropecuária Tropical; v. 44, n. 4, out./dez. 2014; 434-4421983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/pat/article/view/27269/17633Copyright (c) 2020 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessJardini, Debora CuradoScaramuz, Walcylene Lacerda Matos PereiraWeber, Oscarlina Lúcia SantosBorba Filho, Aluisio BrigidoFernandes, Dayane Ávila2020-07-13T15:05:28Zoai:ojs.revistas.ufg.br:article/27269Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:56:05.339409Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true |
