Site specific is a farming management practice with the potential to address management challenges, this approach leverages precise and timely information on agricultural resources to observe and measure variability in field crops. Site -Specific management zones one of the most important pillars of precision agriculture, this technology is designed to enhance management practices by tailoring agricultural treatments to specific production zones within a field, thereby conserving resources, protecting the environment, and improving crop quality. This paper was aim to developed spatial modeling for Site-Specific Management Zones based on soil and plant parameters. This work was done in Agrofood Company with an area approximately 44.5 Faddan planted with potato crop (DITTA variety) in winter session 2019. The Soil samples were taken before planting the crop and plant samples were taken during the three growth stages based on the grid system, Soil and plant variability maps were produced based on Geostatistical analysis from laboratory analysis of the samples. Spatial Model was developed to delineate site-specific management zones using arcgis 10.8, the input factors to developed this model were Soil maps (N, P, K, Ph, ECe, OM), plant maps (N, P, K, chl-a, chl-b), yield data maps and NDVI to create Site -Specific management zones for the study area. The results showed that Management zones were classified into two Zones, which are zone (I) with an area 26.07 Fadden and its characteristics by high crop yield, good soil parameters, on the other hand zone (II) with an area 18.47 Fadden and its characteristics by low crop yield, low soil and plants parameters
