SANTIAGO-MEJIA, Elizabeth et al. Fruit quality of peach trees growing under the milpa system intercropped with fruit trees in hillsides. Agric. Téc. Méx [online]. 2008, vol.34, n.2, pp.159-166. ISSN 0568-2517.

Nutritional status of peach trees affects fruit quality, in peach "Diamante" under the Milpa System Intercropped with Fruit trees (MIAF) in hillsides, with a similar fertilization on level soils, is variable. Then nutritional status and fruit quality as affected by two planting densities (D), two rates of fertilization to maize and beans (F), and two branch position in tree (R) in two locations of San Jerónimo Tecoatl country, in the state of Oaxaca during the year 2005 were evaluated. Eight different combinations (factorial 2³) were tested in a complete randomized block experimental design with three replicates. Foliar analysis in site "Santa Catarina" indicated that only concentrations of Mn and Zn were different between treatments, due to effects of interaction D x F x R and by main effect of F, respectively. In site "Centro de Salud", Mg and Cu were significantly affected by D and interaction F x R, respectively. Total soluble solids were greater than 11.0 °Brix and color index was acceptable. However, fruit firmness was lower (0.40-62 kg cm^-2) than normal for peach "Diamante". Nutritional status of trees was unbalanced with high N concentrations, in detriment of fruit firmness.
