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...
