Spatial Analysis of Yield and Soil Components in an Onion Field

Abstract

The main objective of this study is to determine spatial variability in a dry onion fi eld in EL-Saff agricultural farming village, Giza Governorate, Egypt, 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 salt (EC), pH, available N-P-K and onion yield. Longitudinal slope was also measured. Results were used to produce maps. Most percentage of the fi eld soils was determined as sand to sandy loam textured soils and loamy sand in lower depth. Their surface is covered with many fi ne and medium gravel
