Yield goal is often considered when choosing fertilizer rates for field crops. Spatial stability of yield exists in cotton. If the response of cotton to nitrogen rate is known, yield maps from previous seasons might be used to determine nitrogen rate and help prevent deficient or excessive applications. The response of cotton to nitrogen on the soil used in this study is well documented. In 1998, the yield of over fifty test plots was measured. In 1999, the plots were split, with one side receiving a conventional uniform nitrogen rate and the other side receiving a site-specific rate. There was no significant difference in yield between the two treatments. More research is needed to determine if yield maps may be used to determine nitrogen rate.
