Delineation of Management Zones for Site-Specific Management of Potato Crop in Some Areas in Western Nile Delta, Egypt

S ITE 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 aims 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 18.69 hectares (ha) planted with potato crop (DITTA variety) in winter session 2019. 21 soil samples were taken before planting the crop and 21 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 of laboratory analyses 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 for Nitrogen (N), Phosphors (P), Potassium ( K), pH, electrical conductivity (ECe), calcium carbonate (CaCO3) 3 ) and soil organic carbon (SOM), plant maps for NPK, Chlorophyll a, Chlorophyll b, Carotenoids (Car) yield data maps and normalized difference vegetation index (NDVI) to create Site-Specific management zones for the study area. The results showed that management zones were classified into two zones, which zone (I) with an area 10.94 Hectares and its was characterized by high crop yield and good soil parameters, on the other hand zone (II) with an area 7.75 hectares and it was characterized by low crop yield, low soil and plants parameters.
