Resumo: The objective of this work was to parameterize and to evaluate the DSSAT/Canegro model for five Brazilian sugarcane varieties. The parameterization was done using biometric and growth data from the varieties CTC 4, CTC 7, CTC 20, RB 86‑7515, and RB 83‑5486, obtained in five Brazilian locations. Local sensitivity analysis was performed for the main parameters. Model parameterization was done using the generalized likelihood uncertainty estimation (Glue) method. The predictions were evaluated using the coefficient of determination (R²), Willmott’s D‑index, and the root mean square error (RMSE) as statistical indexes. CTC varieties showed D values ranging from 0.870 to 0.944 for leaf area index, stalk height, tillering, and sucrose content. The RB 83‑5486 variety showed similar results for sucrose content and fresh matter mass of stalks, whereas the RB 86‑7515 variety showed values ranging from 0.665 to 0.873 for all variables analyzed.

A parametrização foi realizada a partir do uso de dados biométricos e de crescimento das variedades CTC 4, CTC 7, CTC 20, RB 86‑7515 e RB 83‑5486, obtidos em cinco localidades brasileiras. Foi realizada análise de sensibilidade local para os principais parâmetros. A parametrização do modelo foi feita por meio da técnica de estimativa da incerteza de probabilidade generalizada (“generalized likelihood uncertainty estimation”, Glue). Para a avaliação das predições, foram utilizados, como indicadores estatísticos, o coeficiente de determinação (R2), o índice D de Willmott e a raiz quadrada do erro‑médio (RMSE). As variedades CTC apresentaram índice D entre 0,870 e 0,944, para índice de área foliar, altura de colmo, perfilhamento e teor de sacarose. A variedade RB 83‑5486 apresentou resultados similares para teor de sacarose e massa de matéria fresca do colmo, enquanto a variedade RB 86‑7515 apresentou valores entre 0,665 e 0,873, para as variáveis avaliadas.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCAPES, EMBRAPANassif, Daniel Silveira PintoMarin, Fabio RicardoPallone Filho, Wander JoséResende, Ronaldo SouzaPellegrino, Giampaolo Queiroz2012-04-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/11106Pesquisa Agropecuaria Brasileira; v.47, n.3, mar. 2012; 311-318Pesquisa Agropecuária Brasileira; v.47, n.3, mar. 2012; 311-3181678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/11106/6815https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/11106/6529info:eu-repo/semantics/openAccess2012-06-17T12:23:29Zoai:ojs.seer.sct.embrapa.br:article/11106Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2012-06-17T12:23:29Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
