Özet (Çeviri)

The main objectives of this research were to determine the correlation between UAV and Sentinel-2 Satellite, predict pasture yield using UAV and Satellite images, and observe deficit irrigation effects for pasture yield. This study was conducted at Lewiston and Panguitch, Utah. UAV images before each harvest in 2017 and one harvest in 2018 were used to find the correlation. Normalized difference vegetation index (NDVI) calculated with UAV data and Sentinel-2 Satellite data were used to determine the correlation. The results of this study indicated that Sentinel-2 and UAV had good correlations with R² = 0.90 for all observations. This relationship makes it possible to extend datasets to predict the yield. NDVI analysis were made using UAV on small and larger areas. Yield estimations for pastures in Panguitch and Lewiston, Utah were made using NDVI from UAV and Sentinel-2 data. For Panguitch, highest correlation was found 49 days before the harvest with R² = 0.96 and RMSE = 0.04 tons/acre, but in general good correlations were found 15 days before the harvest with R²=0.80 or higher. The second highest correlation was 10 days before harvest with R² = 0.86 and RMSE = 0.07 tons/acre iv for Panguitch. At Lewiston, the highest correlation was found 21 days before the harvest with R²= 0.93 and RMSE = 0.04 tons/acre. At Lewiston research plots with full season irrigation and irrigation until August had more yield than no irrigation, irrigation through May, and irrigation through July plots. The less irrigation had lower yield. Full season irrigated plots had almost 20 percent more yield than non-irrigated plots in average of the years in this study, whereas irrigation until August had 6 percent less yield than full season irrigated plots. However, deficit irrigation did not matter in terms of yield apart from nonirrigated plots in Panguitch, Utah. The effects of deficit irrigation after 5 years were assessed visually using NDVI and there was no impact on crop health in the Lewiston study area.
