This study was carried out in the main Escarcha variety peach producing area in the state of Tlaxcala, Mexico. Soil parameters were evaluated in plots with different management and some quality criteria in the fruit, to later relate them through a Principal Component Analysis (PCA). The results of the soil characterization evidenced a predominance of the sand fraction, low concentration of organic matter and total N, and few exchange sites. Yields of 10.88 to 11.66 t ha-1 were obtained. Through the PCA it was observed that the predictor variables in the case of the soil, in the main component one (CP1) were organic matter, organic carbon, total nitrogen and phosphorus; in CP2 were the apparent density, porosity, pH and the humification index. In the case of the fruit, in CP1 were weight, equatorial diameter, maturity index and number of fruits, and in CP2 were total titratable acidity an...
