          Abstract

          Durante seis anos (1990 a 1995), foram avaliados, no CEPAGRO-Centro de Extensão e Pesquisa Agronômica, da Faculdade de Agronomia da Universidade de Passo Fundo (UPF), em Passo Fundo, RS, quatro sistemas de produção de grãos com pastagens anuais de inverno. Os sistemas foram constituídos por: sistema I (trigo/soja, aveia-preta pastejada/soja e aveia-preta pastejada/soja); sistema II (trigo/soja e aveia-preta + ervilhaca pastejadas/milho); sistema III (trigo/soja, aveia-preta + ervilhaca pastejadas/soja e aveia-preta + ervilhaca pastejadas/milho); e sistema IV (trigo/soja, aveia-branca/soja e aveia-branca/soja). O delineamento experimental foi em blocos ao acaso, com três repetições, e parcelas totalizando 500 m². Na média dos seis anos, o sistema II mostrou maior receita líquida (R\(432,71/ha) do que o sistema IV (R\) 322,93/ha). Por sua vez, o sistema II não diferiu significativamente dos sistemas I (R\(377,93/ha) e III (R\) 400,27/ha). A integração lavoura pecuária sob sistema de cultivo plantio direto foi viável tanto para as culturas de inverno e de verão como para a engorda de bovinos no período invernal.

          During six years (1990 to 1995), at the CEPAGRO-Centro de Extensão e Pesquisa Agronômica, of the Faculdade de Agronomia da Universidade de Passo Fundo, in Passo Fundo, RS, Brazil, the effects of grain production systems and annual winter pastures were assessed. The economic analysis on that period is presented in this paper. Four production systems were evaluated: system I (wheat/soybean, grazed black oats/soybean, and grazed black oats/soybean); system II (wheat/soybean and grazed black oats + grazed common vetch/pasture/corn); system III (wheat/soybean, grazed black oats + grazed common vetch/soybean, and grazed black oats + grazed common vetch/corn); and system IV (wheat/soybean, white oats/soybean, and white oats/soybean). An experimental design in blocks at random, with three replications and plots with 500 m², was used. In the average of six years, system II showed a higher net return (R\(432.71/ha), as compared to system IV (R\) 322.93/ha). System II showed no significant differences in relation to systems I (R\(377.93/ha) and III (R\) 400.27/ha). The integration crop-livestock under no-tillage was viable for both winter and summer crops, as well as for fattening beef cattle during winter time.
