According to the results of the analysis of the soil samples taken from the production field in the Research and Application Farm of the Central Research Institute of Field Crops in 2021, a significant relationship was found between yield and NDVI and between yield and organic matter at 0.01 level. There was a significant negative relationship between lime and NDVI at 0.01 level. Increasing lime content negatively affected plant growth, which resulted in a decrease in NDVI. The positive significant correlation between NDVI, organic matter and yield indicates that NDVI value increases with increasing plant biomass. Increased biomass has added more soil organic matter. In 2021, when the yield change depending on NDVI was examined; it was observed that the yield was higher in the central and western parts of the plots where NDVI was higher, and the yield decreased in the eastern parts where the lakeshore strip was located due to the decrease in NDVI. According to the correlation results between the analysis results of soil samples taken from the farmer's field in 2021, yield values and NDVI data; a significant relationship was found between yield value and NDVI, water saturation, EC, organic matter and potassium at 0.01 level. Again, the relationship between yield and phosphorus was determined at 0.05 level. There was a significant negative relationship between yield and lime at 0.05 level.
