Resumo: Behavioural assessment of cultivars adapted to climate and soil variations is essential for recommending genetic materials to producers, achieving higher profitability, and, mainly, targeting regional growth. The aim of this study was to evaluate the agronomic performance of upland rice cultivars in different cropping periods and Cerrado vegetation soil in the southern region of the state of Tocantins. The experiments were conducted in a field at the Chaparral Farm and at the Experimental Station of the Federal University of Tocantins in the agricultural years of 2008/2009, 2009/2010, 2010/2011, 2011/2012, and 2012/2013 with cultivars BRS-Bonança, BRS-Primavera, and BRSMG-Conai. A randomized block experimental design was used with four replications in a factorial scheme of 3 × 5, comprising three genotypes and five years. The evaluated characteristics were as follows: number of days to flowering, plant height, weight of hundred grains, and grain yield. The highest upland rice yield was observed in the cropping period of 2012/13, which also had the highest volume and better distribution of rainfall; flowering time was lesser and greater for BRSMG-Conai and BRS-Bonança cultivars, respectively. The BRS-Primavera cultivar showed the highest grain yield in different years in Cerrado soil in the southern region of the state of Tocantins.

Objetivou-se com este trabalho avaliar o comportamento agronômico de cultivares de arroz de terras altas em diferentes safras sob solo de vegetação de Cerrado do sul do Estado do Tocantins. Os experimentos foram conduzidos nos anos agrícolas de 2008/2009, 2009/2010, 2010/2011, 2011/2012 e 2012/2013 com as cultivares BRS-Bonança, BRS-Primavera e BRSMG-Conai. O delineamento experimental foi de blocos casualisados com quatro repetições, num esquema fatorial 3 x 5, constituído por três genótipos e cinco anos. As características avaliadas foram número de dias para florescimento, altura da planta, massa de cem grãos e produtividade de grãos. As maiores produtividades de grãos de arroz de terras altas foram alcançadas na safra 2012/13, que apresentou maior volume e melhor distribuição da precipitação pluvial; O tempo de florescimento foi menor e maior para as cultivares BRSMG-Conai e BRS-Bonança respectivamente; A cultivar BRS-Primavera apresentou as maiores produtividades de grãos nos diferentes anos sob solo de vegetação de Cerrado no sul do Estado do Tocantins.UEL2016-08-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa experimentalapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1822410.5433/1679-0359.2016v37n4p1699Semina: Ciências Agrárias; Vol. 37 No. 4 (2016); 1699-1708Semina: Ciências Agrárias; v. 37 n. 4 (2016); 1699-17081679-03591676-546Xreponame:Semina.
