2 Fluid Journal Fall 2002 Figure 2. Effects of starter application method and composition on corn grain yield, Scandia, Kansas, 2001. 180 NPK-lbs/A 15-15-5 30-15-5 15-15-5 15-15-5 15-15-5 30-15-5 30-15-5 30-15-5 190 200 210 220 230 240 250 Yield-bu/A In-Furrow 2x2 Dribble 2x Row Band was lower when starter was applied in- furrow with the seed than when applied 2 x 2 below the seed (Figure 2). Dribble application in a narrow surface band two inches to the side of the seed row resulted in yields equal to 2 x 2 applied starter, indicating a surface band application was equal to sub-surface starter placement. The band-over-the- row treatment resulted in yields greater than the in-furrow treatment but less than the 2 x 2 or surface band treat- ments, possibly due to placement on top of the ridge and in a wider (8-inch) band. Increasing N rates in the starter up to 30 lbs/A in the starter, however, did not further increase yields. Drs. Lamond and Gordon are professors, and Niehues and Olsen are former graduate student, Deparment of Agronomy, KSU.
