GONZALEZ, Mirta G.; MORENO, Gisela; GIARDINA, Ernesto B.  e  DI MIRO, Mariano. Excess water in the soil: effect on fruit quality of peach prunus persica (l.) batsch. Cienc. suelo [online]. 2006, vol.24, n.1, pp.59-63. ISSN 1850-2067.

Peach is a perennial culture that requires for its growth soils without limitations, on the basis of it the objective of this work was to study the chemical changes produced in soils on flooding conditions, from flowering to fruit production, relating it to the quality and amount of the fruit. The experiment was a done at an Argiudoll soil of vertic characteristics, with an outstanding Bt horizon that has 35- 38% of clay. Two treatments were made: control, without flooding (c) and with flooding (T). In the treatment (C), the hydric availability was subject to the climatic conditions that happened during the test, including the accomplishment of complementary irrigation allowing at any moment soil to stay in optimal conditions of moisture. The results of the test were related to changes in soil chemical characteristics. Flooded soils had, deficient levels of phosphorus and potassium that resulted in a smaller yield (Fresh and dry weight of fruit). Chemical analyses in plant followed the same tendency in relation to the contents of total nitrogen, phosphorus and potassium that diminished substantially as the content of dry matter, that was reflected in the diminution of the quality of fruit in relation to its firmness and size.
