This research had the objective of evaluating the organic fertilization effects on the production, quality, post-crop conservation and acceptability of fruits of the yellow passion fruit plant (Passiflora edulis, Sims f. flavicarpa Degener). The experiment was established in March 2004, in a red yellow Latosol of Sementeira Experimental Farm - UFV, in Visconde do Rio Branco, MG. The experimental design was completely randomized with 4 repetitions. The treatments were formed by three types of fertilizations applied in the orchard: Mineral (MIN) suitable for the culture (control); Organic (ORG), equivalent to the potassic fertilization suitable for the culture and 2 times organic (2XORG), where was used the ORG treatment double dose. The organic fertilizer used was the bovine fertilizer. In May 2005, fruits from each treatment were transported to the Agro-ecology Laboratory UFV, for quality and post-crop conservation evaluation. In June 2005 fruits from each treatment were selected and transported to the Sensorial Analysis Laboratory of the Food Technology Department UFV, for juice acceptability and fruits appearance evaluation. The yellow passion fruit plant production fertilized with 2XORG and MIN was 26% superior when compared to the plants fertilized with ORG production. The fruits classification (mass and number of defects), was not influenced by the fertilizations. The fruits mass loss from plants fertilized with bovine manure (ORG and 2XORG) was smaller than fruits from plants fertilized with MIN. The fruits fertilized with bovine manure chemicals characteristics (pH, SST, ATT, Vitamin C) were similar to the one of the fruits from plants fertilized with MIN. The fruits juice acceptability from the 3 fertilizations was similar, however, with relation to the appearance, the acceptability was larger for the fruits of the treatment 2XORG.
