NOGUEIRA, Ângela Maria; CARVALHO, Samuel Pereira de; BARTHOLO, Gabriel Ferreira  e  MENDES, Antônio Nazareno Guimarães. Vegetative vigor and yield evaluations of coffee cultivars, "Catuai Vermelho" and "Amarelo" (Coffea arabica L.) planted isolated and different combinations. Ciênc. agrotec. [online]. 2005, vol.29, n.1, pp.27-33. ISSN 1413-7054.  https://doi.org/10.1590/S1413-70542005000100003.

One experiment was conducted at EPAMIG`s experimental station at São Sebastião do Paraíso, MG, to evaluate yield characteristics and vegetative vigor, of "Catuaí Vermelho" (IAC 44, IAC 81, and IAC 99), "Catuai Amarelo" (IAC 47, IAC 62, and IAC 86), coffee lineage cultivars from 1994 to 1999, planted isolated and  in  different  combinations.  An  experimental  randomized blocks design was used, with 3 replications 14 lineages combination as treatment, each plot with six plants, spaced 3.5 by 1.0 m, respectively among interrows and lines. Lineages cultivars were grouped and planted isolated and in multi-lines at proposition of 33% and 50%. Characteristics were evaluated individually, and averages  compared  by  Duncan  test.  Coffee  cultivars combinations planted in multi-lines showed greater yield and greater vigor plants as compared to isolated planting.  "Catuaí Vermelho" IAC 44 cultivar in combination with the IAC 81 and the lineage combinations of the IAC 81 and IAC 99 at 50% proportion of each, showed positive interaction by the fact of to present greater yield than when planted isolated. Take in account lineages of "Catuaí Amarelo", better combination was found with IAC 47 by IAC 62 at 50% proportion. There were no differences in vegetative vigor among lineages; some differences occurred is due to environment interactions with lineage.
