Abstract
Two field experiments were conducted at Nubaria Agric . Res . Station during the two successive summer seasons 1998 and 1999 to study the effect of tillage systems ( no - tillage - complete tillage ) and three nitrogen fertilizer levels 30 , 60 and 90 Kg N / fed . on yield of both maize and soybean as will as competitive relations of maize and soybean A split plot design with three replications was used where the main plots were occupied by tillage systems in both solid and intercropping. The nitrogen fertilizer levels were arranged at random in the sub-plots in both solid and intercropping planting . The obtained results indicated that tillage systems had a significant effect on seed yield of soybean and grain yield of maize in the two seasons and all components of soybean plant except 100 - seed weight in the first season only . Maximum seed yield of soybean and grain yield of maize were obtained with tillage systems . The complete tillage gave highest seed yield and grain yield per fed of soybean and maize in both solid and intercropping compared to that of no-tillage . The solid stand gave highest seed and grain yield per fed of both crops . Increasing nitrogen fertilizer levels significantly increased yield per fed of soybean and maize . The maximum yield of both crops were obtained by adding 90 Kg N / fed . The results indicated that land equivalent ratio LER of maize and soybean values was more than one moreover, maize was always dominant crop , whereas soybean was dominated . It could be recommended that for producing maximum intercropped yield of soybean and maize with those treatments had a complete tillage system and increasing nitrogen fertilizer levels up to 90 Kg N/ fed.
