Summary: Studies of potential and yield potential are extremely important worldwide, to identify and narrow yield potential. The objective of this study was to simulate cassava yield potential and water-limited yield potential using the Simanihot model. Cassava yield gap and the planting date effect were estimated for two locations in Rio Grande do Sul, Brazil (Santa Maria and São Luiz Gonzaga). Due to weather conditions, in Santa Maria cassava cycle was defined as annual and São Luiz Gonzaga as annual and biannual. Planting dates were set from August 1st 2017 to May 1st 2018, and harvested on Jun 15th 2018. Results showed that cassava express higher yield potential on early planting (August 10th), achieving 64.6 Mg ha-1 and 50.2 Mg ha-1 of tuber roots and 47.3 Mg ha-1 and 38.9 Mg ha-1 of aboveground biomass, in São Luiz Gonzaga and Santa Maria, respectively. Planting dates after the beginning of the climatic risk zoning, present a yield reduction of 0.364 Mg ha-1 in São Luiz Gonzaga and 0.282 Mg ha-1 in Santa Maria, for each day of delay on the planting date. These results indicate that planting cassava during the first ten days of August expresses the highest yields and reduces the gaps for both locations.

O objetivo deste estudo foi estimar o potencial produtivo através do modelo Simanihot e quantificar a lacuna de produtividade na cultura da mandioca para dois locais do Rio Grande do Sul. Foram utilizados para as simulações os municípios de Santa Maria (cultivo anual) e São Luiz Gonzaga (cultivo anual e bianual). As datas de plantio foram definidas desde primeiro de agosto de 2017 até primeiro de maio de 2018. O melhor potencial de produtividade encontrado para a cultura da mandioca neste estudo foi 64,6 Mg ha–1, 50,2 Mg ha–1 de raízes e 47,3 Mg ha-1, 38,9 Mg ha-1 de parte aérea, respectivamente para São Luiz Gonzaga e para Santa Maria. Os plantios a partir do zoneamento de risco climático, apresentam uma lacuna de 0,364 Mg ha-1 em São Luiz Gonzaga e 0,282 Mg ha-1 em Santa Maria a cada dia de atraso. Estes resultados apontam que a antecipação do plantio para o primeiro decêndio de agosto expressa as maiores produtividades e diminuem as lacunas para ambos os locais.Universidade do Estado de Santa Catarina2020-09-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.udesc.br/index.php/agroveterinaria/article/view/1567510.5965/223811711932020263Revista de Ciências Agroveterinárias; Vol. 19 No. 3 (2020); 263 - 269Revista de Ciências Agroveterinárias; v. 19 n. 3 (2020); 263 - 2692238-1171reponame:Revista de Ciências Agroveterinárias (Online)instname:Universidade do Estado de Santa Catarina (UDESC)instacron:UDESCporhttps://periodicos.udesc.br/index.php/agroveterinaria/article/view/15675/12027Copyright (c) 2020 Revista de Ciências Agroveterinárias (Journal of Agroveterinary Sciences)info:eu-repo/semantics/openAccessBorges, Josias MoreiraZanon, Alencar JuniorSilva, Michel Rocha daBalest, Darlan ScapiniAlves, Alexandre FerigoloFreitas, Charles Patrick de Oliveira deBoth, VanderleiSantos, Amanda Thirza Lima2022-04-26T15:39:56Zoai::article/15675Revistahttps://periodicos.udesc.br/index.php/agroveterinaria/PUBhttps://periodicos.udesc.br/index.php/agroveterinaria/oairca.cav@udesc.br | portal.periodicos@udesc.brhttps://doi.org/10.5965/223811712238-11711676-9732opendoar:2022-04-26T15:39:56Revista de Ciências Agroveterinárias (Online) - Universidade do Estado de Santa Catarina (UDESC)false
