Resumo: | Sorghum is a commonly grown plant in the Central-West region of Brazil as a second crop; however, it is grown almost exclusively as a second crop after maize in the state of Paraná (South region). The growth of sorghum crops is an option for areas or times in which the growth of maize crops can be risky. Thus, the objective of this work was to evaluate the agronomic characteristics of eight sorghum hybrids (ADV-123, ADV-114, 1G100, 50A10, 1G244, 50A40, 50A50, and 1G282) grown in three sowing times in two agricultural years: 2014 (February 20, March 02, and March 03) and 2015 (February 09, February 19, and March 01), and four maize hybrids in 2014 (DKB-330-Pro, P-3431-HX, Formula-TL, and AG-9010-Pro) and five maize hybrids in 2015 (DKB-330-Pro, P-3431-HX, Formula-TL, DKB-275-Pro, and DKB-290-Pro), in the same sowing times used for sorghum. A randomized complete block experimental design with a split-plot factorial arrangement was used, with the sowing times in the plots and the hybrids in the sub-plots. The variables evaluated were: number of days from sowing to flowering, leaf area index, 1,000-grain weight, grain yield, number of spikelets per panicle, for the sorghum crop; and number of rows per ear and number of grains per row, for the maize crop. The comparison between the two crops showed that the sorghum maintained higher production stability in the different sowing times. |

O cultivo de sorgo pode ser uma opção de semeadura em áreas ou épocas cuja a cultura do milho possa ser considerada de risco. Assim, objetivou-se com trabalho avaliar as características agronômicas de oito híbridos de sorgo (ADV 123, ADV 114, 1G100, 50A10, 1G244, 50A40, 50A50 e 1G282), em três datas de semeadura nos anos agrícolas de 2014 (20/02, 02/03 e 12/03) e 2015 (09/02, 19/02 e 01/03) e quatro híbridos de milho em 2014 (DKB 330 Pro, P 3431 HX, Formula TL e AG 9010 Pro) e cinco híbridos no ano de 2015 (DKB 330 Pro, P 3431 HX, Formula TL, DKB 275 Pro e DKB 290 Pro), nas mesmas datas de semeadura utilizada para o sorgo. O delineamento experimental foi em blocos completos casualizados em esquema fatorial em parcelas subdivididas, sendo nas parcelas alocadas as datas de semeadura e nas sub parcelas os híbridos. Foi avaliado o número de dias da semeadura até o florescimento (DAP), índice de área foliar (IAF), massa de mil grãos (MMG), produtividade (kg ha-1) número de espiguetas por panícula no sorgo (EPP), e no milho o número de fileiras por espiga (NFE) e número de grãos por fileira (NGF). Ao comparar as culturas, o sorgo conseguiu manter maior estabilidade produtiva em diferentes datas de semeadura.Universidade Federal Rural do Semi-Árido2021-09-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/971310.1590/1983-21252021v34n405rcREVISTA CAATINGA; Vol. 34 No. 4 (2021); 780-790Revista Caatinga; v. 34 n. 4 (2021); 780-7901983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/9713/10740Copyright (c) 2021 Revista Caatingainfo:eu-repo/semantics/openAccessVieira, Paulo Vinicius DemeneckFreitas, Paulo Sérgio Lourenço deSilva, Andre Luiz Biscaia Ribeiro daSouza, Ana Claudia SossaiVoroniak, Juliana Marques2023-07-04T13:31:28Zoai:ojs.periodicos.ufersa.edu.br:article/9713Revistahttps://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:2024-04-29T09:46:52.156681Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
