Resumo: The Southern Brazilian Wheat Research Board reports every year a list of cultivars recommended for each wheat (Triticum aestivum L.) growing area of Rio Grande do Sul state along with the sowing date intervals in each region. In order to establish the best sowing date within the recommended period, a variance analysis on yield response was carried out in a group of 27 cultivars in the period of trial conducted in three different dates at Passo Fundo, RS, Brazil, during the years of 1983, 1984 and 1985. The results showed that the influence of year, sowing date, cultivar, as well as the interaction effects of year x sowing date, year x cultivar, sowing date x cultivar, and year x sowing date x cultivar were highly significant. It was not possible to determine for all cultivars the best sowing date for this region. Nevertheless, it was observed that the second sowing date showed to be more suitable for most of the cultivars.

Visando a determinar qual o melhor período de plantio, dentro da época recomendada, foi feita a análise de variância, com base nos resultados do Ensaio Estadual de Cultivares Recomendadas de Trigo do RS - semeado em três diferentes épocas no Centro Nacional de Pesquisa de Trigo, Passo Fundo, RS, nos anos de 1983, de 1984 e de 1985 -, das respostas, em rendimento de grãos, de 27 cultivares nesses três anos. Os resultados evidenciaram ser altamente significativa a influência de ano, de época e de cultivar, bem como as interações ano x época, ano x cultivar, época x cultivar e ano x época x cultivar. Não foi possível determinar para todas as cultivares a melhor época de plantio de trigo para essa região. No entanto, verificou-se que a segunda época de plantio foi a mais favorável para a maioria das cultivares testadas.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraMoreira, João Carlos SoaresIgnaczak, João Carlos2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/13981Pesquisa Agropecuaria Brasileira; v.23, n.8, ago. 1988; 895-902Pesquisa Agropecuária Brasileira; v.23, n.8, ago. 1988; 895-9021678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/13981/7946info:eu-repo/semantics/openAccess2014-09-16T17:11:54Zoai:ojs.seer.sct.embrapa.br:article/13981Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-16T17:11:54Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
