The use of strip tillage may hold promise, especially on the claypan soils in the southeastern part of Kansas which also extend into parts of Oklahoma and Missouri.  Strip tillage may have benefits of maintaining residue cover while providing a warmer and drier zone in claypan soils for corn emergence in the early spring.  The objectives were to compare the effectiveness of strip tillage done in either late fall or late winter with reduced tillage and no tillage and to determine the effect of fluid N-P fertilizer applied either surface band (dribble) or subsurface band (knife) in late fall or late winter.  The experiment was a split-plot arrangement of a randomized complete block with 3 replications.  The whole plots were tillage system: 1) no tillage, 2) reduced tillage (disc once in late fall and once in late winter), 3) strip tillage done in late fall, and 4) strip tillage done in late winter.  The subplots were a 2 × 2 factorial arrangement of N-P application method (dribble - 76 cm centers and knife - 76 cm centers and 10 cm deep) and fertilization timing (late fall and late winter).  Liquid fertilizer rates were 135 lb N/ha and 45 lb P₂O₅/ha.  Short-season corn yields were affected by a year × tillage interaction.  In 2003, there were no differences in short-season corn yields as affected by tillage.  In 2004, however, reduced tillage resulted in greater yield than with no-till or with strip tillage done in the spring.  By 2005, reduced tillage resulted in 50% greater yield than with no-tillage or either strip-tillage system.  Averaged across years, knife applications resulted in nearly 11%  greater yield than did dribble applications.  Fertilization done in early spring  resulted in significantly greater corn yields (7.4 Mg/ha) than with late fall fertilization (6.7 Mg/ha).
