The peach-trees cultivation is a very economic important activity in South of Brazil, where highlights the State of Rio Grande do Sul as the largest Brazilian producer. One of the most important aspects in actuality is the food prodution with reduction of agrochemicals components, reducing the risks of environment contamination. This work aimed to compare the Conventional Production systems (PC) and Integrated systems (PI) of peaches cultivation and took place in the year of 2001, in the county of São Jerônimo - RS, latitude 30°05'52" S, longitude 51°39'08" W and altitude of 46 meters. Commercial orchand areas of cv. Marli was evaluated regarding the mains handling practice of plant and soil, phytosanitary control, economic aspects, as well as fruit production and quality. In the area under PI, were used the handling practices praised by the Norms of Production Integrated of Peach (NPIP) and in the area conducted the PC system, the plants were managed according to the practices usually used by the producer. The peaches production, in both systems, was not affected. The area of PI, occured smaller number of peaches per plant, however the fruit was larger middleweight. Most peaches of PI were classified like CAT I (diameter up to 57 mm). The fruits produced in the PC were of the CAT II (48 to 57 mm). Regarding to titratable acidity, flesh firmness and epidermal color there was no difference between peaches from either system.With these results, we can conclude that is possible to produce quality peaches with productivity in PI's system.
