Resumo: – Manure, if managed and used properly, is a good source of nutrients for crop production. To evaluatethe effects of manure and N fertilizer applied on soil surface on corn grain yields, in no-tillage and conventionaltillage systems, a field trial was carried out on a Red Latosol (Oxisol) in Chapecó, Santa Catarina State, Brazil.The experiment was placed under randomized blocks design with split-plots and four replications.The main plotswere represented by different soil tillage (conventional tillage and no-tillage), and the sub-plots by doses of pigslurry (zero, 60, 120 and 240kg N/ha) and sources of N (ammonium nitrate and poultry house litter), applied atthe dose of 120kg N/ha. Corn grain yield response was observed for all N sources. In all four years, pig slurry Nhad similar efficiency to ammonium nitrate N on corn yield. In conventional tillage system there were nosignificant differences on corn yield among the N sources but in no-tillage system the surface poultry house litterapplication had a lower performance.There were no interaction effects of tillage and N rates (pig slurry) on cornyields. The maximum grain yield was estimated with an annual application of 192kg N/ha of pig slurry.

O trabalho foi desenvolvido em LatossoloVermelho distroférrico típico, no município de Chapecó, SC, no período de 1998 a 2002. O delineamento experimental foi em blocos ao acaso com parcelas subdivididas e quatro repetições. Nas parcelas foram avaliadosos sistemas de preparo do solo plantio direto (SPD) e convencional (SPC) e nas subparcelas, doses de ES para suprir zero, 60, 120 e 240kg/ha de N e EA e NA aplicados na dose para suprir 120kg/ha de N, além de uma testemunha, sem adubo. Houve resposta significativa do milho à adubação nitrogenada. As maiores produtividades foram obtidas com utilização de NA e ES. Em aplicação superficial, sem incorporação, o EA apresentou menor eficiência em comparação ao ES, que teve eficiência similar ao NA, tanto no SPC como no SPD. A máxima eficiência técnicafoi estimada para uma aplicação anual de 192kg/ha de N-ES.
