The effect of soil management, with mulching on the planting line, on the quality of post-harvest of peaches cv. Cerrito during cold storage was studied. The treatments were consisted by fruits harvested on orchards with mulching (oats) and without mulching (traditional cultivation) on three stages of maturation. The storage was performed at temperature 0º C and above 90% of air humidity. Evaluations of firmness, acidity (TTA), total soluble solid (TSS) and coloration, were performed at harvest and after 6, 12 and 18 days of storage, plus 3 days of commercialization simulation. The fruits harvested on orchards with mulching presented a larger firmness than the others. The percentage of TSS was larger in peaches produced in the orchards with traditional cultivation. The management of the soil didn't influenced the relation TSS/TTA and acidity. The peaches produced in the orchard with mulching of oat presented prevalence of the greenish coloration in the beginning of the storage.
