Abstract: Pig farming is considered one of the activities with the greatest environmental impact due to the erroneous disposal of swine waste. The present work aimed to produce an organic compost using waste from pig production and evaluate its chemical characteristic, corn yield under doses of this organic compost and soil nutritional quality before and after the experiment implementation. The Corn was fertilized at sowing and 30 days after plant germination using organic compost from pig waste at the doses- 0, 2, 3, 4 and 5 t ha-1. The Corn used was CATIVERDE 02 and were seeded at 1.0 m spacing between rows and 0.40 m between plants, in a total area of 240 m2. The experimental design was randomized blocks with four replications and five doses of organic compost. The parameters evaluated for corn were- plant height, stem diameter, weight and corncob length. Fertilization with swine organic compost increases in soil P, K, Ca, even after the corn harvest. The best treatment was with a dose of 5 t ha-1, as it resulted in higher plant height (1.85 m) and corn cob weight (261 g).
