Resumo: | A balanced nutrition can aid in the control of the coffee diseases. Thus, the objective was to evaluate the effect of nitrogen and potassium fertilization in a growth chamber in assessing the intensity of bacterial blight. We used the susceptible cultivar Mundo Novo 376/4. The treatments consisted of five doses of N (3, 7, 11, 15 and 19 mmol L-1) combined with five doses of K (3, 5, 7, 9 and 11 mmol L-1) in a factorial 5 x 5, a total of 25 treatments and three replicates composed of two seedlings. The experimental design was completely randomized. The incidence and severity was assessment. Then, the area under disease progress curve of incidence (AUDPCI) and severity (AUDPCS) were calculated. There was a higher incidence of the disease (97.2%) in the combination of larger doses of N and K. There was a significant difference only for N in AUDPCS, dry mass of plant and chlorophyll a, b and total. The lower AUDPCS (7.79) was obtained with the dose 13.34 mmol L-1 N. There was a significant positive correlation to chlorophyll a, b and total with N and AUDPCS. |

Assim, objetivou-se avaliar o efeito da adubação nitrogenada e potássica na intensidade da mancha aureolada do cafeeiro, em câmara de crescimento. Utilizou-se a cultivar Mundo Novo 376/4, suscetível à doença. Os tratamentos consistiram de cinco doses de N (3, 7, 11, 15 e 19 mmol L-1) combinadas com cinco doses de K (3, 5, 7, 9 e 11 mmol L-1), em esquema fatorial 5 x 5, totalizando 25 tratamentos e três repetições compostas por duas mudas em solução nutritiva. O delineamento experimental foi o inteiramente casualizado. Avaliou-se a incidência e a severidade da doença. A área abaixo da curva de progresso da incidência (AACPDI) e da severidade (AACPDS) foi calculada. Observou-se a maior incidência da doença (97,2%) na combinação das maiores doses de N e K. Houve diferença significativa apenas para o N na AACPDS, massa da planta seca e clorofilas a, b e total. A menor AACPDS (7,79) foi obtida com a dose 13,34 mmol L-1 de N. Houve correlação significativa e positiva para as clorofilas a, b e total com o N e a AACPS.Editora UFLA2017-03-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfimage/jpegimage/jpegimage/jpegimage/jpegapplication/vnd.openxmlformats-officedocument.wordprocessingml.documentapplication/vnd.openxmlformats-officedocument.wordprocessingml.documenthttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/1210Coffee Science - ISSN 1984-3909; Vol. 12 No. 1 (2017); 60 - 68Coffee Science; Vol. 12 Núm. 1 (2017); 60 - 68Coffee Science; v. 12 n. 1 (2017); 60 - 681984-3909reponame:Coffee Science (Online)instname:Universidade Federal de Lavras (UFLA)instacron:UFLAporhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/1210/pdf_1210https://coffeescience.ufla.br/index.php/Coffeescience/article/view/1210/1696https://coffeescience.ufla.br/index.php/Coffeescience/article/view/1210/1697https://coffeescience.ufla.br/index.php/Coffeescience/article/view/1210/1698https://coffeescience.ufla.br/index.php/Coffeescience/article/view/1210/1699https://coffeescience.ufla.br/index.php/Coffeescience/article/view/1210/1700https://coffeescience.ufla.br/index.php/Coffeescience/article/view/1210/1701Copyright (c) 2017 Coffee Science - ISSN 1984-3909https://creativecommons.org/info:eu-repo/semantics/openAccessPérez, Cristian David PlazaPozza, Edson AmpélioPozza, Adélia Aziz AlexandreFreitas, Aurivan SoaresSilva, Marília Goulart2017-03-30T16:15:17Zoai:coffeescience.ufla.br:article/1210Revistahttps://coffeescience.ufla.br/index.php/CoffeesciencePUBhttps://coffeescience.ufla.br/index.php/Coffeescience/oaicoffeescience@dag.ufla.br||coffeescience@dag.ufla.br|| alvaro-cozadi@hotmail.com1984-39091809-6875opendoar:2024-05-21T19:53:59.665966Coffee Science (Online) - Universidade Federal de Lavras (UFLA)true |

A balanced nutrition can aid in the control of the coffee diseases. Thus, the objective was to evaluate the effect of nitrogen and potassium fertilization in a growth chamber in assessing the intensity of bacterial blight. We used the susceptible cultivar Mundo Novo 376/4. The treatments consisted of five doses of N (3, 7, 11, 15 and 19 mmol L-1) combined with five doses of K (3, 5, 7, 9 and 11 mmol L-1) in a factorial 5 x 5, a total of 25 treatments and three replicates composed of two seedlings. The experimental design was completely randomized. The incidence and severity was assessment. Then, the area under disease progress curve of incidence (AUDPCI) and severity (AUDPCS) were calculated. There was a higher incidence of the disease (97.2%) in the combination of larger doses of N and K. There was a significant difference only for N in AUDPCS, dry mass of plant and chlorophyll a, b and total. The lower AUDPCS (7.79) was obtained with the dose 13.34 mmol L-1 N. There was a significant positive correlation to chlorophyll a, b and total with N and AUDPCS. |
