- MULTIVARIATE AND CANONICAL MODELS APPLIED TO CORN: BENEFITS OF GREEN MANURE WITH Vigna unguiculate Luiz Leonardo Ferreira Lucas Eduardo Dalbosco Ivan Ricardo Carvalho Ariana Bertola Carnevale Natã Balssan Moura Francine Lautenchleger Ingeniería Zea mays green manure soil coverage Aiming at increasing productivity and maintaining the equilibrium of the corn crop system, the objective of this work was to analyze the phenotypic correlations of cowpea as an alternative of green manure in corn crop. The study was conducted in rural Mineiros, GO, Brazil. The soil was classified as Quartzarenic Neossol. The experimental design was randomized blocks in factorial 6x2, corresponding to 6 corn hybrids [Syn7613, 20A78, DKB310, CD3770, P3250 and P3646] in two fertilization methods [(Green Manure System - GMS: Caupi bean straw - Vigna unguiculata L.) and (Conventional Fertilization System - CFS: formulated 8-25-15)], in 4 repetitions. In the implementation of CFS, 480 kg ha-1 of formula 8-25-15 were used; whereas for the GMS, 231 kg ha-1 of MAP and 124 kg ha-1 of KCl were used to compensate for the P and K elements of the CFS. The cultural management pertinent to pest control were performed using the best practices of integrated pest management. The obtained data were submitted to the assumptions of the statistical model, verifying the normality and homogeneity of the residual variances, as well as the additivity of the model. Uni and multivariate models were used. The analyzes were performed at the interface Rbio and R, besides the Software Genes. It was identified in the analysis of phenotypic correlations that the CD3770 corn hybrid was efficient when used cowpea as an alternative of green manure. 2020 artículo científico 1518-1634 https://www.redalyc.org/articulo.oa?id=481582835007 en http://www.redalyc.org/revista.oa?id=4815 HOLOS application/pdf Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Norte HOLOS (Brasil) Vol.7
