Conteúdo: | In this work, the application of poultry litter for corn crop, its influence on the weed community and the interrelation with mechanical and chemical control methods were investigated. Before management, weed phytosociological analysis were done, adopting six treatments and six replications. A randomized blocks design in a factorial 2x5+2 was adopted to evaluate the control methods. The first factor was the form of control, application of herbicide nicosulfuron in post emergence and mechanical control (hand weeding). The second factor was the doses of poultry litter that corresponded to 0, 50, 100, 200 and 300% of corn N recommendation. The checks consisted of the two methods of weed control associated with recommended N using mineral fertilizer. The corn plant height was evaluated at 14 and 28 days after management. The results showed that the incorporation of poultry litter promoted changes in the relative importance of weed species, until the time of control. The weed control method did not affect corn yield; however, the plant height 47 days after sowing with mechanical control was higher. With the poultry litter dose corresponding to 200% of the recommended nitrogen, corn grain yield was similar to that obtained with mineral fertilizers. Key words: Systems fertilization, anticipation of fertilization, organic fertilization, Zea mays.
