Resumo: The choice of cultivars adapted to different regions and the determination of the best sowing dates are indispensable tools for crop development. This allows the installation of the crop in times favorable to its development, as well as cultivars that manage to reach their maximum yield potential. The objective of this study was to determine the best sowing dates and the cultivars that can adapt to the low-altitude Cerrado region and have the best development and yield efficiency. The experiment was conducted on a typical clayey dystrophic Red Latosol soil. The experimental design was in randomized blocks in a factorial scheme, comprised by four sowing dates during the spring/summer season (October, November, December, and February) and in each sowing date there were eight upland rice cultivars (BRS Esmeralda, ANa 6005, ANa 5015, IPR 117, IAC 203, IAC 500, ANa 7211 and BRSGO Serra Dourada) with four replicates. Sowing in October and November benefited the aerial dry mass and the spikelets fertility however, sowing in November provided higher plant height, which caused lodging in plants. Sowing in December caused the incidence of scald, mainly affecting the cultivar ANa 7211. For all cultivars, sowing in October favored the yield efficiency of upland rice in the low-altitude Cerrado, followed by sowing in November. The cultivars which demonstrated higher yield efficiency in the conditions of the region were BRS Esmeralda and ANa 5015.

Isso permite a instalação da lavoura em épocas favoráveis ​​ao seu desenvolvimento, bem como cultivares que consigam atingir seu máximo potencial produtivo. O objetivo deste estudo foi identificar as melhores épocas de semeadura e as cultivares que podem se adaptar à região do Cerrado de baixa altitude e ter a melhor desenvolvimento e eficiência produtiva. O experimento foi conduzido em um solo típico de Latossolo Vermelho distrófico argiloso. O delineamento experimental foi em blocos casualizados, em esquema fatorial, com quatro épocas de semeadura durante a primavera/verão (outubro, novembro, dezembro e fevereiro), cada uma com oito cultivares de arroz de terras altas (BRS Esmeralda, ANa 5015, ANa 6005, IPR 117 , IAC 500, IAC 203, BRSGO Serra Dourada e ANa 7211) e quatro repetições. A semeadura em outubro e novembro beneficiou a massa seca da parte aérea e a fertilidade das espiguetas, entretanto, a semeadura em novembro proporcionou maior altura das plantas, o que causou o acamamento de plantas. A semeadura em dezembro causou incidência de escaldadura, afetando principalmente a cultivar ANa 7211. Para todas as cultivares, a semeadura em outubro favoreceu a eficiência produtiva do arroz de terras altas no Cerrado de baixa altitude, seguido pela semeadura em novembro. As cultivares que demonstraram maior eficiência de produção nas condições da região foram BRS Esmeralda e ANa 5015.EDUFU2022-08-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/5411010.14393/BJ-v38n0a2022-54110Bioscience Journal ; Vol. 38 (2022): Continuous Publication; e38040Bioscience Journal ; v. 38 (2022): Continuous Publication; e380401981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/54110/34385Brazil; Contemporary Copyright (c) 2022 Flávia Constantino Meirelles, Orivaldo Arf, Nayara Fernanda Siviero Garcia, Anderson Teruo Takasu, Fernando de Souza Buzo, José Roberto Portugal, Amanda Ribeiro Peres Portugalhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessConstantino Meirelles, FláviaArf, OrivaldoFernanda Siviero Garcia, NayaraTeruo Takasu, Andersonde Souza Buzo, FernandoRoberto Portugal, JoséRibeiro Peres Portugal, Amanda2022-08-05T14:54:51Zoai:ojs.www.seer.ufu.br:article/54110Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-08-05T14:54:51Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false
