A spatial variable N rate trial and remote sensing of cotton crop was conducted during 2003 at Paul Good Farms, Mississippi, USA. For N rate trial three transects each consists of 8 rows were selected at east and west side of the field. The three N treatments (UAN, urea-ammonium nitrate solution) were 0, 112 and 185 kg N/ha. Multispectral aerial images were collected with a 0.5 m spatial resolution of cotton crop throughout growing season. The statistical analysis showed that the highest cotton lint yield was obtained from the highest UAN_N treatment i.e.185 kg N/ha followed by 112 and 0 kg N/ha.
