In this work the effects produced by two treatments onmaize crop samples have been studied. Analysis of maize grain based on twotypes of agronomical conditions was performed on: (a) lots treated withdifferent fertilizers and (b) lots with different crop density. Analysis wascarried out by microwave induced plasma with optical emission spectrometry (MIPOES) and included the quantification of 11 elements: Ca, Cd, Cr, Cu, Fe, Mg,Mn, Ni, P, Pb and Zn. With the purpose of understand the effect of agriculturalpractices on elemental profile, principal components analysis (PCA) and clusteranalysis (CA) were used as chemometrics tools, finding a correct grouping ofeach crop based on the type of treatment. The obtained models can be useful toevaluate agricultural strategies, as well as for determining potential yieldsin maize crops.
