Resumo: | Sugarcane is one of the main crops explored in Brazil, whether under rainfed or irrigated conditions. Water and the nutrient potassium are inputs that can interfere with the physiology of this crop and, when supplied in fertigation, allows for greater efficiency in the use of water and fertilizers. Potassium is the nutrient most required by sugarcane and its efficiency is improved when fertigation is used. Thus, the objective was to evaluate the physiological responses of sugarcane during the third cropping cycle (stump) regarding the application of potassium doses under rainfed and irrigation conditions. The experiment was carried out in a split-plot scheme (4 x 2), with four doses of potassium fertilization (0, 70, 140 and 210 kg ha-1 of K2O) with and without irrigation. The stomatal conductance was higher when the sugarcane plants were irrigated at all doses of potassium studied, except for the control at 235 and 393 days after cutting. The SPAD index showed no difference between irrigated and dryland conditions in all doses of potassium fertilization and evaluation periods. There is a difference in the leaf area index between irrigated plants and under rainfed conditions only when the dose of 140 kg ha-1 of K2O is applied 340 days after cutting. |

Water and the nutrient potassium are inputs that can interfere with the physiology of this crop and, when supplied in fertigation, allows for greater efficiency in the use of water and fertilizers. Potassium is the nutrient most required by sugarcane and its efficiency is improved when fertigation is used. Thus, the objective was to evaluate the physiological responses of sugarcane during the third cropping cycle (stump) regarding the application of potassium doses under rainfed and irrigation conditions. The experiment was carried out in a split-plot scheme (4 x 2), with four doses of potassium fertilization (0, 70, 140 and 210 kg ha-1 of K2O) with and without irrigation. The stomatal conductance was higher when the sugarcane plants were irrigated at all doses of potassium studied, except for the control at 235 and 393 days after cutting. The SPAD index showed no difference between irrigated and dryland conditions in all doses of potassium fertilization and evaluation periods.

El agua y el nutriente potasio son insumos que pueden interferir con la fisiología de este cultivo y, al ser suministrados en fertirrigación, permiten una mayor eficiencia en el uso de agua y fertilizantes. El potasio es el nutriente más requerido por la caña de azúcar y su eficiencia mejora cuando se usa fertirrigación. Así, el objetivo fue evaluar las respuestas fisiológicas de la caña de azúcar durante el tercer ciclo de cultivo (tocón) respecto a la aplicación de dosis de potasio en condiciones de secano y riego. El experimento se realizó en un esquema de parcelas divididas (4 x 2), con cuatro dosis de fertilización potásica (0, 70, 140 y 210 kg ha-1 de K2O) con y sin riego. La conductancia estomática fue mayor cuando las plantas de caña de azúcar fueron irrigadas con todas las dosis de potasio estudiadas, excepto para el control a los 235 y 393 días después del corte. El índice SPAD no mostró diferencias entre las condiciones de regadío y de secano en todas las dosis de fertilización con potasio y períodos de evaluación. Existe una diferencia en el índice de área foliar entre plantas irrigadas y de secano solo cuando se aplica la dosis de 140 kg ha-1 de K2O 340 días después del corte.A cana-de-açúcar é uma das principais culturas exploradas no Brasil, seja em condições de sequeiro ou irrigada. A água e o nutriente potássio são insumos que podem interferir na fisiologia dessa cultura e, quando fornecido em fertirrigação, permite uma maior eficiência do uso da água e de fertilizantes. O potássio é o nutriente mais exigido pela cana-de-açúcar e a sua eficiência é melhorada quando se utiliza a fertirrigação. Assim, objetivou-se avaliar as respostas fisiológicas da cana-de-açúcar durante o terceiro ciclo de cultivo (soqueira) quanto à aplicação de doses de potássio em condições de sequeiro e irrigação. O experimento foi desenvolvido em esquema de parcelas subdivididas (4 x 2), sendo quatro doses de adubação potássica (0, 70, 140 e 210 kg ha-1 de K2O) com e sem irrigação. A condutância estomática foi maior quando as plantas de cana-de-açúcar foram irrigadas em todas as doses de potássio estudadas, exceto para o controle aos 235 e 393 dias após o corte. O índice SPAD não apresentou diferença entre as condições irrigado e sequeiro em todas as doses de adubação potássica e épocas de avaliação. Há diferença no índice de área foliar entre as plantas irrigadas e em condições de sequeiro apenas quando se aplica a dose de 140 kg ha-1 de K2O aos 340 dias após o corte.Research, Society and Development2021-11-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2252610.33448/rsd-v10i14.22526Research, Society and Development; Vol. 10 No. 14; e549101422526Research, Society and Development; Vol. 10 Núm. 14; e549101422526Research, Society and Development; v. 10 n. 14; e5491014225262525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/22526/19884Copyright (c) 2021 Pedro Henrique Ribeiro; Glauber José de Castro Gava; Adolfo Bergamo Arlanch ; Marconi Batista Teixeira; Evaldo Alves dos Santos; Fernando Rodrigues Cabral Filho; João Alberto Lelis Neto; Fernando Nobre Cunha; Daniely Karen Matias Alves; Alefe Viana Souza Bastos; Edson Cabral da Silva; Vitor Marques Vidal; Wilker Alves Moraishttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessRibeiro, Pedro Henrique Gava, Glauber José de Castro Arlanch , Adolfo Bergamo Teixeira, Marconi Batista Santos, Evaldo Alves dos Cabral Filho, Fernando Rodrigues Lelis Neto, João Alberto Cunha, Fernando Nobre Alves, Daniely Karen Matias Bastos, Alefe Viana Souza Silva, Edson Cabral da Vidal, Vitor Marques Morais, Wilker Alves 2021-12-04T11:48:39Zoai:ojs.pkp.sfu.ca:article/22526Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:41:40.036441Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
