Resumo: The objective of this work was to simulate rice grain yield in climate change scenarios with increasing of current atmospheric CO2 concentration and increases in mean air temperature in Santa Maria, RS, as well as to verify possible implications on current recommendations of sowing period. Climate change scenarios for the next one hundred years considering doubled CO2 concentration and increases of 1, 2, 3, 4 and 5°C were used. Rice grain yield was simulated with the InfoCrop model. Simulations were performed considering three rice cultivars – IRGA 421, IRGA 417 and EPAGRI 109 – and seven sowing dates spaced monthly from July 20th to January 20th. An increase in rice grain yield was observed in the climate change scenarios simulated for the three cultivars, with higher increase for the very early cultivar (IRGA 421) and lower increase for the late cultivar (EPAGRI 109). If climate change takes place, currently sowing period recommended for irrigated rice shall be enlarged.

Foram utilizados cenários de mudanças climáticas, para os próximos 100 anos, com o dobro da quantidade de CO2 e com aumentos de temperatura do ar de 1, 2, 3, 4 e 5°C. O rendimento de grãos da cultura do arroz foi simulado com o modelo InfoCrop. As simulações foram realizadas para três cultivares de arroz (IRGA 421, IRGA 417 e EPAGRI 109) em sete datas de semeadura, com intervalos mensais, de 20 de julho até 20 de janeiro. Um aumento no rendimento de grãos de arroz irrigado foi observado nos cenários de mudanças climáticas simulado para as três cultivares, com maior incremento na muito precoce (IRGA 421) e menor na de ciclo longo (EPAGRI 109). Se as mudanças climáticas se confirmarem, o período de semeadura recomendado atualmente para cultivares de arroz irrigado deverá ser ampliado.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCNPq, CAPESWalter, Lidiane CristineRosa, Hamilton TellesStreck, Nereu Augusto2011-01-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/8437Pesquisa Agropecuaria Brasileira; v.45, n.11, nov. 2010; 1237-1245Pesquisa Agropecuária Brasileira; v.45, n.11, nov. 2010; 1237-12451678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/8437/6091https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/8437/4136info:eu-repo/semantics/openAccess2014-11-13T16:12:17Zoai:ojs.seer.sct.embrapa.br:article/8437Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-11-13T16:12:17Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
