(Escola Superior de Agricultura "Luiz de Queiroz", 2023-10-23)The coffee sector is estimated to have a retail market value in excess of USD 83 billion, and over 125 million jobs have been created in the global coffee chain. The coffee specialty market has recently increased significantly, ... -
(Escola Superior de Agricultura "Luiz de Queiroz", 2023-08-14)This work evaluated the initial performance and genetic diversity of Coffea canephora genotypes cultivated in environments at contrasting altitudes. Fourteen morphophysiological traits and seven descriptors of the genus ...
-
(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", 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", 2021)Land use and tillage practices may change soil structure and undermine sustainable agriculture; however, such changes are hardly identified in the short term. In this sense, agroforestry systems have been used to reduce ...

Receptor-Like Kinase (RLK) as a candidate gene conferring resistance to Hemileia vastatrix in coffee(Escola Superior de Agricultura "Luiz de Queiroz", 2021)The biotrophic fungus Hemileia vastatrix causes coffee leaf rust (CLR), one of the most devastating diseases in Coffea arabica. Coffee, like other plants, has developed effective mechanisms to recognize and respond to ...
-
(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", 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", 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", 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", 2009-01)The study of pest distributions in space and time in agricultural systems provides important information for the optimization of integrated pest management programs and for the planning of experiments. Two statistical ...
-
(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", 2019-05)Tetrazolium tests use conventional sampling techniques in which a sample has a o Zootecnia, Av. Visconde do Rio Preto, s/n — 36301-360 — fixed size. These tests may be improved by sequential sampling, which does not work ...
-
(Escola Superior de Agricultura "Luiz de Queiroz", 2019-03)Awareness of evapotranspiration (ET) and crop coefficient (Kc) is necessary for irrigation management in coffee crops. ET and Kc spatial variabilities are disregarded in traditional methods. Methods based on radiometric ...
-
(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", 2014-03)Agroforestry systems are an alternative option for sustainable production manage- ment. These systems contain trees that absorb nutrients from deeper layers of the soil and leaf litter that help improve the soil quality ...
-
(Escola Superior de Agricultura "Luiz de Queiroz", 2008-12)Despite the importance of leaf wetness duration for plant disease epidemiology, there has been little attention paid to research on how its variability relates to different cropping situations. The objective of this study ...
-
(Escola Superior de Agricultura "Luiz de Queiroz", 2008-07)Vegetables have a natural defense against external factors synthesizing phenolic compounds, which depends on the maturity stage and on the climate. Total phenol grades were extracted from mature and young coffee leaves and ...
-
(Escola Superior de Agricultura "Luiz de Queiroz", 2010-11)Coffee (Coffea Arabica L.) plantations using adapted cultivars to regional environmental conditions with optimal plant population density and adequate nutrition are expected to show high yield responses. The triennial ...
-
(Escola Superior de Agricultura "Luiz de Queiroz", 2006-03)Establishing field water balances is difficult and costly, the variability of their components being the major problem to obtain reliable results. This component variability is presented herein for a coffee crop grown in ...
