Resumo: | The viticulture in the semiarid region of Brazil stands out in the country due to the expansion of its cultivated area and increased production, especially in the sub-mid São Francisco Valley. However, the supplying of water and an efficient replacement of nutrients to the soil are essential for these crops, due to the intrinsic climatic conditions of this region, such as low rainfall and high evapotranspiration. This study aimed at evaluating the physiological characteristics of ‘Itália’ grapevine (Vitis vinifera L.) under irrigation and fertilization management. The experiment was conducted in a randomized block design, with four replications, in a split-plot arrangement, with four irrigation water depths (0.75, 1.00, 1.25 and 1.5 times the crop coefficient) in the plots and four fertilizer rates (100 %, 75 %, 50 % and 25 %, based on the recommended fertilizer rates for this crop) in the subplots, with addition of organic compounds. The leaf water potential, leaf chlorophyll content, relative water content, photosynthesis, stomatal conductance, internal CO2 partial pressure, leaf temperature and biomass accumulation in the berries were evaluated. The highest leaf chlorophyll contents were found in treatments with fertilizer rates of 70-85 %. Stomatal conductance decreased with the increasing irrigation water depths, thus reducing the internal CO2 partial pressure and increasing the leaf temperature and air vapor pressure deficit. The reduction of 25 % in the conventional fertilization and irrigation of 135 % of the recommended coefficient resulted in the highest average weight of berries. The highest yields were obtained with the lowest irrigation water depths and fertilizer rates of 50-65 %. |

No entanto, devido às condições climáticas intrínsecas da região, como baixas precipitações pluviométricas e elevada demanda evapotranspirativa, o fornecimento de água é indispensável aos cultivos, assim como uma eficiente reposição de nutrientes ao solo. Objetivou-se analisar variáveis fisiológicas de videira ‘Itália’ (Vitis vinifera L.) submetida a irrigação e adubação. Utilizou-se delineamento experimental em blocos casualizados, em esquema de parcelas subdivididas, sendo as parcelas quatro fatores de multiplicação do coeficiente de cultura (0,75; 1,00; 1,25; e 1,5) e as subparcelas quatro doses de adubação (100 %, 75 %, 50 % e 25 % da adubação recomendada), acrescidas de um produto orgânico, com quatro repetições. Foram avaliadas as variáveis potencial hídrico foliar, índice de clorofila foliar, conteúdo relativo de água, fotossíntese, condutância estomática, pressão parcial de CO2 interno, temperatura foliar e acúmulo de biomassa nas bagas. Os maiores índices de clorofila foliar foram obtidos com adubações de 70-85 %. Houve redução da condutância estomática com o aumento da lâmina de irrigação, reduzindo-se, assim, a pressão parcial de CO2 interno e aumentando-se a temperatura foliar e o déficit de pressão de vapor. Com a redução da adubação convencional em 25 % e irrigação de 135 % do coeficiente recomendado, obteve-se o maior peso médio de bagas. As maiores produtividades foram obtidas com as menores lâminas de irrigação e níveis de adubação de 50-65 %.Escola de Agronomia - Universidade Federal de Goiás2017-12-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://revistas.ufg.br/pat/article/view/48640Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 47, n. 4, Oct./Dec. 2017; 390-398Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 47, n. 4, out./dez. 2017; 390-398Pesquisa Agropecuária Tropical; v. 47, n. 4, out./dez. 2017; 390-3981983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGenghttps://revistas.ufg.br/pat/article/view/48640/24748Copyright (c) 2017 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessMartins de Andrade, Victor PimentaBezerra da Silva, José AliçandroCosta de Souza, José SebastiãoOliveira, Fábio FreireSimões, Welson Lima2020-07-13T18:50:46Zoai:ojs.revistas.ufg.br:article/48640Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:56:17.794743Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true |
