Variabilidade espacial de atributos físicos do solo e características agronômic...
Carvalho, Luis Carlos Cirilo; Da Silva, Fábio Moreira; Ferraz, Gabriel Araújo e Silva; da Silva, Flávio Castro; Stracieri, Juliana [UNESP]Made available in DSpace on 2022-04-29T07:13:29Z (GMT). No. of bitstreams: 0 Previous issue date: 2013-12-01; Precision agriculture differs from the conventional by uniting spatial relationships to the variability in the field, becoming an important management tool of the agricultural systems. Thus, the present study aimed to evaluate, by classical statistics, geoestatistics and principles of precision agricult...
Fuzzy Mapping of Climate Favorability for the Cultivation of Conilon Coffee in ...
Medauar, Caique Carvalho; Silva, Samuel De Assis; Galvao, Icaro Monteiro [UNESP]; Franco, Lais Barreto; Carvalho, Luis Carlos CiriloMade available in DSpace on 2021-06-25T11:47:30Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-01-03; The aim of the present study was to construct agroclimatic zoning for the conilon coffee crop in the state of Bahia, Brazil, using fuzzy logic. Historical data series on rainfall, mean air temperature, and relative air humidity were used. Analyses were carried out considering the mean values of the accu...
Plant sampling grid determination in precision agriculture in coffee field
Ferraz, Gabriel Araújo e Silva; de Oliveira, Marcelo Silva; da Silva, Fábio Moreira; Sales, Ronan Souza; Carvalho, Luis Carlos CiriloThe aim of the present study was to evaluate different grid samples applied to plant properties of a coffee plantation by using precision coffee growing and geostatistical techniques. The study was performed at the Brejão Farm in the municipality of Três Pontas, MG, Brazil, using productivity, the maturation index and the detachment force difference, sampled at georeferenced points. With the intention of choosi...
Comparison between the soil chemical atributes sampled conventionaly and in grid
Ferraz, Gabriel Araújo e Silva; Silva, Fábio Moreira da; Oliveira, Marcelo Silva de; Silva, Flávio Castro da; Carvalho, Luis Carlos CiriloThe aim in this article was to characterize the structure and magnitude of the spatial distribution of soil attributes on a coffee field and map these attributes in order to identify the spatial dependence of them. It was aimed to compare the attribute amount when it was sampled conventionally or in grid sampling. This study was carried out on the Brejão farm in Três Pontas, Minas Gerais state, Brazil. As a dat...
Analysis of spatial variability of force detachment of coffee fruits in central...
Figueiredo, Vanessa Castro; Ferraz, Gabriel Araújo Silva; Silva, Fabio Moreira da; Conceição, Fagner Goes da; Carvalho, Luis Carlos CiriloDue to the importance of coffee to the economy of Brazil and the increase of areas even in zone with water deficits during the year, it is necessary to study the factors involved in its production, especially for mechanized and selective harvesting. At this stage coffee farmers find it difficult to determine the appropriate time to start. This research was carried out to evaluating the spatial variation of forc...
Comparison of sampling leaf conventional and precision for micronutrients analy...
Carvalho, Luis Carlos Cirilo; Silva, Fábio Moreira da; Ferraz, Gabriel Araújo e Silva; Figueiredo, Vanessa Castro; Cunha, João Paulo BarretoOne of the technologies that has been outstanding for the management of crops is the precision of coffee growing. However, there are still many fears on the part of growers in their adoption due to the lack of information to justify its use, compared to the current conventional management. This study aimed to evaluate the spatial and temporal variability of micronutrients (Zn, Fe, Mn, Cu and B) obtained through...
Spatial variability of soil physical attributes and agronomic characteristics o...
Carvalho, Luis Carlos Cirilo; Silva, Fábio Moreira da; Ferraz, Gabriel Araújo e Silva; Silva, Flávio Castro da; Stracieri, JulianaPrecision agriculture differs from the conventional by uniting spatial relationships to the variability in the field, becoming an important management tool of the agricultural systems. Thus, the present study aimed to evaluate, by classical statistics, geoestatistics and principles of precision agriculture, some physical attributes indicative of soil compaction, such as bulk density, soil penetration resistance...
Qualidade física de um latossolo vermelho férrico sob sistemas de uso e manejo
Carvalho Filho, Alberto; Carvalho, Luis Carlos Cirilo; Centurion, José Frederico; Beutler, Amauri Nelson; Cortez, Jorge Wilson; Ribon, Adriana AparecidaA qualidade física do solo é definida como a capacidade do solo manter a produtividade sustentável ao longo dos anos. Para mensurar a qualidade física foram avaliados atributos nas camadas de 0,0-0,10; 0,10-0,20; 0,20-0,30; 0,30-0,40 m em Latossolo Vermelho acriférrico, muito argiloso. O delineamento experimental foi inteiramente casualizado com quatro sistemas de uso (milho, cana-de-açúcar, pastagem e cerrado ...
