Resumo: With the objetive to evaluate the effect of soil tillage methods and crop systems on N uptake and com yield, an experiment was established in 1985 at the University Experimental Station in Eldorado do Sul (RS), Brazil. Thrce soil tillage methods (conventional, reduced and no tillage), three crop systems (oats(Avena strigosa)/corn, oats+clover (Trifolium subterraneum)lcom, oats+clover/corn+cowpea (Vigna unguiculata)) and two leveis of nitrogen(0 and 120 kg/ha) were tested. The results of the first five years of N absorption and com yield are reponcd in this paper. The dry matter yield of winter cover crops and its N contens above ground varied from 2.6 to 6.7 t/ha and 28 to 136 kg/ha, respectively. In 1988, the year of best clover establishment, this pasture had 80 kg/ha of N and the oats 56 kg/ha, in the oats+clover mixture. The com grown after, without N, produced 80% of the yield obtained after oats with 120 kg/ha of N. The tillage methods did not affect the yield and N absorption by com.

O experimento consta de três métodos de preparo do solo (convencional, reduzido e sem preparo), três sistemas de cultura ((aveia(Avena strigosa)/milho, aveia+trevo (Trifolium subterraneum)/milho e aveia+trevo/ milho+caupi (Vigna unguiculata)) e duas doses de N(zero e 120 kg/ha), e foi avaliado nos cinco anos após a sua instalação quanto a absorção de N e rendimento do milho. O rendimento de matéria seca das culturas de cobertura variou entre 2,6 e 6,7 t/ha, e a absorção de N, de 28 a 136 kg/ha. Em 1988, ano de melhor estabelecimento do trevo, esta pastagem continha 80 kg/ha de N e a aveia 56 kg/ha, na consorciação aveia+trevo. O milho cultivado após, sem aplicação de N, produziu 80% do rendimento obtido após a aveia e aplicação de 120 kg/ha de N. Os métodos de preparo do solo não afetaram significativamente o rendi- mento e a absorção de N pelo milho. Departamento de Diagnóstico e Pesquisa Agropecuária.
