Marandu intercropped with Stylosanthes spp. under organic management.h[electronic resource] c2018 ap. 6138-6151 aThis study aimed to evaluate by principal component analysis the relationship among chemical-bromatological composition, fractionation of carbohydrate and protein content, in vitro dry matter digestibility (IVDMD), and dry matter (DM) production of Brachiaria brizantha cv. Marandu intercropped with Stylosanthes spp. under organic and conventional fertilization. Forage chemical quality patterns were assessed for each fertilization management by multivariate analyses. The discriminatory capacity was higher for variables resulting from B. brizantha cv. Marandu analyses than from Stylosanthes spp. However, the expressiveness of these variables had a high similarity with multivariate analyses, mainly when comparing carbohydrate fractionation and IVDMD. In terms of chemical quality and production variables, a principal component analysis proved to be effective for evaluations of different fertilization management types, being more expressive for samples of B. brizantha cv. Marandu. aMultivariate analysis aOrganic production aBrachiaria Brizantha aProdução Orgânica aComposição química bromatotógica aMarandu1 aOKADA, E. S. M.1 aOLIVEIRA, E. R.1 aGABRIEL, A. M.
