The seasonal analysis tool of de CSM-CERES-Maize model was used to assess aboveground dry biomass production under rainfed conditions. The simulations comprised scenarios involving four cultivars (Amarel\u00e3o, AL 30, AG 5011 and AG 122), six nitrogen (N) fertilization strategies, 52 sowing dates, and 21 years of daily weather data. Silage productivity and quality were assessed, and a sowing window was established for each one of the cultivars based on this information. Regardless of the N rate and cultivar, sowings performed between June 26 and December 19 were not at risk of exceeding the deadline for silage harvesting in the region. For sowing occurred on December 19, regardless of the N rate, the average productivity of silage and the average amount of energy per unit area were lower for the creole variety Amarel\u00e3o. For the same sowing date the average values of energy per unit of biomass weight indicated good silage quality, for all cultivars regardless of the N rate.Keywords: family farming, DSSAT, aboveground biomass, Zea mays L.\u00a0ABORDAGEM DE MODELAGEM PARA ESTABELECER ESTRAT\u00c9GIAS DE PRODU\u00c7\u00c3O DE SILAGEM NA MICRORREGI\u00c3O DE PELOTAS, BRASIL \u00a0RESUMO - O objetivo deste estudo foi avaliar estrat\u00e9gias de manejo para melhorar a produ\u00e7\u00e3o de silagem pelos agricultores familiares na microrregi\u00e3o de Pelotas, sul do Rio Grande do Sul (RS), Brasil. A ferramenta de an\u00e1lise sazonal do modelo CSM-CERES-Maize foi usada para avaliar a produ\u00e7\u00e3o de fitomassa seca em condi\u00e7\u00f5es de sequeiro. Foi considerado nas simula\u00e7\u00f5es um cen\u00e1rio com quatro cultivares (Amarel\u00e3o, AL 30, AG 5011 e AG 122); seis estrat\u00e9gias de aduba\u00e7\u00e3o nitrogenada; 52 \u00e9pocas de semeadura; e 21 anos de dados meteorol\u00f3gicos di\u00e1rios. A produtividade e a qualidade da silagem foram avaliadas e, com base nessas informa\u00e7\u00f5es, uma janela de semeadura foi estabelecida para cada uma das cultivares. Independentemente da dose de nitrog\u00eanio e cultivar, as semeaduras realizadas entre 26 de junho e 19 de dezembro n\u00e3o correm risco de exceder o prazo para a colheita de silagem na regi\u00e3o. Para semeadura realizada em 19 de dezembro, independentemente da taxa de N, a produtividade m\u00e9dia de silagem e a quantidade m\u00e9dia de energia por unidade de \u00e1rea foram menores para a variedade crioula Amarel\u00e3o. Para esta mesma \u00e9poca de semeadura, os valores m\u00e9dios de energia por unidade de peso de fitomassa seca indicaram boa qualidade de silagem, para todas as cultivares, independentemente da dose de N.Palavras-chave: agricultura familiar, DSSAT, fitomassa seca da parte a\u00e9rea, Zea mays L.<\/jats:p>","DOI":"10.18512\/1980-6477\/rbms.v16n3p536-555","type":"journal-article","created":{"date-parts":[[2018,1,22]],"date-time":"2018-01-22T19:18:02Z","timestamp":1516648682000},"page":"536","source":"Crossref","is-referenced-by-count":0,"title":["A MODELING APPROACH TO ESTABLISH STRATEGIES FOR MAIZE SILAGE PRODUCTION IN THE MICRO-REGION OF PELOTAS, BRAZIL"],"prefix":"10.18512","volume":"16","author":[{"given":"TALES ANTONIO DO","family":"AMARAL","sequence":"first","affiliation":[]},{"given":"RICARDO NUNO FONSECA GARCIA PEREIRA","family":"BRAGA","sequence":"additional","affiliation":[]},{"given":"ANA CL\u00c1UDIA RODRIGUES DE","family":"LIMA","sequence":"additional","affiliation":[]},{"given":"CAMILO DE LELIS TEIXEIRA DE","family":"ANDRADE","sequence":"additional","affiliation":[]}],"member":"7777","published-online":{"date-parts":[[2017,12,29]]},"container-title":["Revista Brasileira de Milho e Sorgo"],"original-title":[],"link":[{"URL":"http:\/\/rbms.cnpms.embrapa.br\/index.php\/ojs\/article\/viewFile\/758\/pdf_1","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/rbms.cnpms.embrapa.br\/index.php\/ojs\/article\/viewFile\/758\/pdf_1","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2018,2,19]],"date-time":"2018-02-19T14:53:24Z","timestamp":1519052004000},"score":1,"resource":{"primary":{"URL":"http:\/\/rbms.cnpms.embrapa.br\/index.php\/ojs\/article\/view\/758"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,12,29]]},"references-count":0,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2017,12,29]]}},"URL":"https:\/\/doi.org\/10.18512\/1980-6477\/rbms.v16n3p536-555","relation":{},"ISSN":["1980-6477","1676-689X"],"issn-type":[{"value":"1980-6477","type":"electronic"},{"value":"1676-689X","type":"print"}],"subject":[],"published":{"date-parts":[[2017,12,29]]}}}
