Notes:
Abstract In a factorial design lysimeter experiment with corn, in a sandy loam soil, two irrigtion frequencies (low (IL) and high (IH)) and two ways of fertilizer placement (shallow (FS) and deep (FD)), were applied. The plants did not suffer from stress under either water regime. Tillering, degree of grain filling and distribution of nitrogen between the grain and vegetative plant parts, indicated an enhanced plant development in the FS treatment. The IH-FS treatment showed the highest root density in the upper soil layer and the highest grain yield and reduced-nitrogen yield in grain. Results indicate that fertilizer placement influences root density distribution in the soil profile and consequent corn yield.
