- Multivariate analysis for modeling yield variability to define management zones in a banana agroecosystem Lucas Villegas-Santa Darío A. Castañeda-Sánchez Ingeniería site Plant nutrition soil properties cluster analysis specific management The delineation of management zones is based on the spatial behavior of a few soil variables selected and evaluated previously and usually not correlated in situ with yield. Since the soil-plant system is multivariate, the analysis of its complexity requires statistical tools of equal size. These tools are convenient in providing an intuitive interpretation of the relationship between variables and sampling sites ordering. This study aims at the identification of management zones in a banana agroecosystem, starting from the overall analysis of soil variables with crop performance components using multivariate statistical tools. Three clusters of sites were identified based on soil variables; dry mean weight diameter, pH, and (Ca+Mg)/K ratio, all correlated with crop yield. Groupings allowed delineating management zones whose production has a uniform spatial behavior, significantly different between zones (P < 0.01). 2020 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49666177019 https://www.redalyc.org/journal/496/49666177019/ https://www.redalyc.org/journal/496/49666177019/html/ https://www.redalyc.org/journal/496/49666177019/49666177019.epub https://www.redalyc.org/journal/496/49666177019/movil 10.15446/dyna.v87n214.84827 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.214 Vol.87
