Area estimation of soybean leaves of different shapes with artificial neural ne...
Sá, Ludimila Geiciane de; Albuquerque, Carlos Juliano Brant; Valadares, Nermy Ribeiro; Brito, Orlando Gonçalves; Mota, Amara NunesLeaf area is one of the most commonly used physiological parameters in plant growth analysis because it facilitates the interpretation of factors associated with yield. The different leaf formats related to soybean genotypes can influence the quality of the model fit for the estimation of leaf area. Direct leaf area measurement is difficult and inaccurate, requires expensive equipment, and is labor intensive. T...
Influence of base saturation on buckwheat grain and flavonoid production
Fernandes, Thaíse Ohana Moura; Costa, Karoline Paulino; Rocha, Ana Paula de Melo; Fernandes, Luiz Arnaldo; Albuquerque, Carlos Juliano BrantFagopyrum esculentum is highly nutritious due to its proteins of high biological value and high fiber content. Its most relevant property is nonetheless its antioxidant activity, provided by the presence of flavonoids. It is an important pseudocereal in agriculture, animal production, and human food. The objective of study was to evaluate the grain yield and flavonoid production of Fagopyrum esculentum cultivar...
Effect of silicon on aphid populations and wheat yield in Minas Gerais, Brazil
Rezende, Gabriel Fernandes; Sampaio, Marcus Vinicius; Machado, Beliza Queiroz Vieira; Lima, Diego Tolentino de; Perdomo, David NatarenThe area cultivated with wheat has been increasing in the savannahs of the state of Minas Gerais, Brazil.

The southern region of Brazil, the main wheat production area, has had several problems as a result of aphids, but aphid populations and the resulting ...
Efeito de coberturas vegetais sobre os atributos físicos do solo e característi...
Kondo, Marcos Koiti; Albuquerque, Carlos Juliano Brant; Wendling, Beno; Silva, Paulo Barbosa da; Cardoso, Maurício MendesObjetivou-se com a realização deste trabalho avaliar os atributos físicos de solo e as principais características agronômicas do sorgo granífero no sistema de plantio direto em área com diferentes coberturas vegetais. O experimento foi conduzido durante dois anos agrícolas (2008/09 e 2009/10). No primeiro ano foram semeadas sete espécies de gramíneas em consórcio com o sorgo para formação de pastagem, além do s...
