ABSTRACT Portable chlorophyll meters can be used to improve the prediction of nitrogen (N) doses for common bean. This study aimed evaluate two (Minolta SPAD-502 and ClorofiLOG CFL 1030) predict topdressing N Pérola, TAA Gol BRSMG Uai cultivars VR 20 line. Eight field experiments (four genotypes devices) were carried out in a randomized blocks design, with four replicates, being treatments appl...

The present study aimed to evaluate the influence of fertilization formulated at planting and doses nitrogen in topdressing on yield components second-crop corn. experiment was conducted between March June 2018 farm State University Goiás, Unit Ipameri-GO. randomized block design, arranged a 3 x 5 factorial scheme with four replications, used. Three fertilizer formulations (06-22-12; 08-20-15 0...

This research is an outcome of the R&D activities Ecodevelopment S.A. (steadily supported by Hellenic Agricultural Organization—Demeter) towards offering precision farming services to rice growers. Within this framework, a new methodology for topdressing nitrogen prediction was developed based on machine learning. Nitrogen key element in culture and its rational management can increase prod...
