(Escola Superior de Agricultura "Luiz de Queiroz", 2019-05)Plants of Coffea arabica Icatu IAC 925 germplasm show resistance to Meloidogyne paranaensis under field conditions, but with variable rates of segregation. One mother plant, IAC 3, of Icatu IAC 925 was evaluated under ... -
(Escola Superior de Agricultura "Luiz de Queiroz", 2022-04-13)Adaptation to climate change is a strategy for crops to cope with the scenario of rising temperatures worldwide. In the case of Coffea arabica L., the use of agroforestry systems (AFS) with woody species is a promising ...
-
(Escola Superior de Agricultura "Luiz de Queiroz", 2007-05)The use of climatological water balances in substitution to complete water balances directly measured in the field allows a more practical crop management, since the climatological water balances are based on data monitored ...
-
(Escola Superior de Agricultura "Luiz de Queiroz", 2003-10)Microbial control in integrated pest management (IPM) programs of coffee plantations is an important factor for the reduction of pest population densities. The use of selective pesticides can be associated with entomopathogens, ...
-
(Escola Superior de Agricultura "Luiz de Queiroz", 2012-05)Fertilizer application at variable rates requires dense sampling to determine the resulting field spatial variability. Defining management zones is a technique that facilitates the variable-rate application of agricultural ...
-
(Escola Superior de Agricultura "Luiz de Queiroz", 2002-10)Coffee husk and coffee pulp are coffee processing by-products. Coffee husk is obtained when harvested coffee is processed by the dry method, and coffee pulp is produced by the wet method. In Brazil, coffee is usually ...
-
(Escola Superior de Agricultura "Luiz de Queiroz", 2022-09-12)Coffee farmers do not have efficient tools to have sufficient and reliable information on the maturation stage of coffee fruits before harvest. In this study, we propose a computer vision system to detect and classify the ...
-
(Escola Superior de Agricultura "Luiz de Queiroz", 2016-05)Diachasmimorpha longicaudata is an Old World parasitoid of tephritid fruit flies that was widely introduced in the Americas to control pest species such as the Mediterranean fruit fly Ceratitis capitata. Augmentative ...
-
(Escola Superior de Agricultura "Luiz de Queiroz", 1992-01)Na propagação vegetativa através de estacas caulinares, a época de retirada dos ramos, que serão utilizados na confecção das estacas, tem grande influência sobre seu enraizamento. Outro fator de grande relevância é o ...
-
(Escola Superior de Agricultura "Luiz de Queiroz", 2002-10)A atividade de polifenoloxidase (PFO) tem sido usada como indicadora da qualidade de bebida de café. Foram feitas comparações entre o método tradicionalmente usado para extração de polifenoloxidase de café e outro, onde ...
-
(Escola Superior de Agricultura "Luiz de Queiroz", 2007-09)The Citrus Variegated Chlorosis and the Coffee Leaf Scorch are some of the many destructive diseases caused by Xylella fastidiosa, a gram-negative bacterium limited to the xylem of affected plants. As its genetic ...
-
(Escola Superior de Agricultura "Luiz de Queiroz", 2005-07)One of the greatest problems in Coffea arabica breeding is identifying precisely any inbred line, based only on botanical and agronomical descriptors, because of the reduced genetic variability of the species, close pedigree ...
-
(Escola Superior de Agricultura "Luiz de Queiroz", 2021)Genomic selection (GS) emphasizes the simultaneous prediction of the genetic effects of thousands of scattered markers over the genome. Several statistical methodologies have been used in GS for the prediction of genetic ...
-
(Escola Superior de Agricultura "Luiz de Queiroz", 2005-03)In view of the low N concentration in organic fertilizers, it is necessary to use high rates of such fertilizers to attend coffee crop requirements. Hence, N is the most limiting nutrient for organic coffee production. The ...
-
(Escola Superior de Agricultura "Luiz de Queiroz", 2007-09)The relationship between growth and fertilizer nitrogen recovery by perenial crops such as coffee is poorly understood and improved understanding of such relations is important for the establishment of rational crop ...
-
(Escola Superior de Agricultura "Luiz de Queiroz", 2019-09)Meloidogyne species are widely distributed in coffee growing areas in Brazil, where M. paranaensis is responsible to significant losses to the crop. One of the main management strategies is the use of resistant cultivars, ...
-
(Escola Superior de Agricultura "Luiz de Queiroz", 2008-05)Citrus variegated chlorosis (CVC) and coffee stem atrophy (CSA) are important diseases in Brazil associated with closely-related strains of Xylella fastidiosa, but little is know about host overlapping and importance of ...
-
(Escola Superior de Agricultura "Luiz de Queiroz", 2016-07)Humic substances (HS) comprise the passive element in soil organic matter (SOM), and represent one of the soil carbon pools which may be altered by different cover crops and weed control methods. This study aimed to assess ...
-
(Escola Superior de Agricultura "Luiz de Queiroz", 1992-01)O presente trabalho teve como finalidade, estudar o efeito de auxinas e do boro no enraizamento de estacas caulinares de Coffea arabica L. cv. "Mundo Novo". As estacas foram retiradas de ramos ortotrópicos semi-lenhosos ...
-
(Escola Superior de Agricultura "Luiz de Queiroz", 2003-04)One management practice of which the efficiency has not yet been scientifically tested is spraying coffee plants with diluted sucrose solutions as a source of carbon for the plant. This paper evaluates the effect of foliar ...
