Resumo: Production models need to be tested at different locations to be used as an agricultural planning tool. Hydric relations and performances of water-crop production models were used to estimate ratoon sugarcane yield along nine production cycles, in Paranavaí, Paraná State, Brazil. The crop reference and real evapotranspiration, soil water storage, water deficit and surplus were evaluated. The “Stewart” and “Jensen” models showed the best performance to estimate ratoon sugarcane yield. Water availability in the first development phase of ratoon sugarcane has the greatest influence on yield.

Avaliaram-se, ao longo de nove ciclos de cultivo, as relações hídricas e o desempenho de modelos de produção água-cultura, na estimativa da produtividade de cana-soca, em Paranavaí (PR). Estimou-se a evapotranspiração de referência e real da cultura, armazenamento de água no solo, deficiência e excedente hídrico. Os modelos de “Stewart” e “Jensen” obtiveram os melhores desempenhos para estimar a produtividade de cana-soca. A disponibilidade hídrica na primeira fase de desenvolvimento da cana-soca exerce a maior influência na produtividade.Escola de Agronomia - Universidade Federal de Goiás2016-01-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://revistas.ufg.br/pat/article/view/37687Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 45, n. 4, Oct./Dec. 2015; 426-433Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 45, n. 4, out./dez. 2015; 426-433Pesquisa Agropecuária Tropical; v. 45, n. 4, out./dez. 2015; 426-4331983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGenghttps://revistas.ufg.br/pat/article/view/37687/19948Copyright (c) 2020 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessSouza, Jorge Luiz Moretti deGerstemberger, EmersonGurski, Bruno CésarOliveira, Ricardo Augusto de2020-07-13T16:36:24Zoai:ojs.revistas.ufg.br:article/37687Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:56:09.797575Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true
