Autor: Marco A. Zanella, Daniel M. de Queiroz, Domingos S. M. Valente, Francisco de A. de C. Pinto, Nerilson T. Santos

Publikováno v: Engenharia Agrícola, Vol 39, Iss 5, Pp 676-683 (2019)

ABSTRACT The delimitation of management classes is critical for successful precision agriculture. This process involves choosing the variables to use and analyzing the spatial variability of the variables. Thus, the objective of this study was to ana

Spatial variability of apparent electrical conductivity and soil properties in a coffee production field

Autor: Domingos S. M. Valente, Daniel M. de Queiroz, Francisco de A. de C. Pinto, Fábio L. Santos, Nerilson T. Santos

Publikováno v: Engenharia Agrícola, Vol 34, Iss 6, Pp 1224-1233 (2014)

Precision agriculture based on the physical and chemical properties of soil requires dense sampling to determine the spatial variability of these properties. This dense sampling is often expensive and time-consuming. One technique used to reduce samp

Discriminação entre estágios nutricionais na cultura do trigo com técnicas de visão artificial e medidor portátil de clorofila Machine vision techniques and multivariate classifiers for nitrogen fertilization doses discrimination in wheat

Autor: Darly G. de Sena Júnior, Francisco de A. de C. Pinto, Daniel M. de Queiroz, Nerilson T. Santos, Joseph K. Khoury Júnior

Publikováno v: Engenharia Agrícola, Vol 28, Iss 1, Pp 187-195 (2008)

O ajuste da adubação nitrogenada é um tema que suscita preocupações econômicas e ambientais em todo o mundo. Isso decorre da elevada resposta das culturas, especialmente gramíneas, ao nitrogênio e da falta de métodos adequados de quantifica�

Geração de zonas de manejo para cafeicultura empregando-se sensor SPAD e análise foliar Coffee crop management zone delimitation using chlorophyll index and leaf analysis

Autor: Francelino A. Rodrigues Junior, Luciano B. Vieira, Daniel M. de Queiroz, Nerilson T. Santos

Publikováno v: Revista Brasileira de Engenharia Agrícola e Ambiental-Agriambi, Vol 15, Iss 8, Pp 778-787 (2011)

Objetiva-se, com este trabalho, definir zonas de manejo para cafeicultura por meio dos métodos K-Means e Fuzzy C-Means, com base em determinações realizadas com sensor de clorofila e por análise foliar, e avaliar as zonas de manejo obtidas usando
