Corn is planted directly into the strip without tillage the following spring.
Grain yield Trt. A tillage x starter fertilizer interaction was not found. There was no year x tillage interaction, indicating similar behavior among tillage systems for each year. There were no starter fertilizer interactions with year or tillage systems, indicating similar responses to starter fertilizer each year and for each tillage system. These data suggest that band applications of P at a half-rate to low testing soils are not sufficient to optimize corn yields compared to broadcast applications of P at a full rate.
