Objective of this study is to determine spatial variability in a dry onion fi eld and to produce a management strategy which is based on spatial variability of yield and soil components. The onion fi eld properties were determined and given in maps. Soil samples were taken to determine properties of soil such as pH, salt, humidity, CaCO3, organic matter, total N, Zn, Fe, P2O5, Ca+Mg, K, texture. Longitudinal slope was also measured. Results were used to produce maps. Most percentage of the fi eld soils was determined as clay-loam. Small part of the fi eld was loam. Yield of dry onion decreased by increasing of Organic Matter, Total Nitrogen, Iron, and Zinc in the fi eld according to the related maps. Relationship between yield and phosphorous, CaCO3, Ca+Mg and salt was positive according to the related maps.
