چکیده
Yield prediction before harvest is one of the important issues in terms managing agricultural policies and making right decisions for future. Using remote sensing techniques yield estimation studies steps many countries to reach their 21st-century targets. The aim this study develop a wheat model using Landsat-8 Sentinel-2 satellite data. In study, development stages winter were examined with help images obtained between years 2015-2018 selected region Sanliurfa, Turkey, it was aimed predict yields other by establishing model. established Normalized Difference Vegetation Index (NDVI), Soil-adjusted (SAVI), Green (GNDVI) Modified (MSAVI) from images. Linear regression analysis calculated NDVI, SAVI, GNDVI, MSAVI indices, actual values on pre-flowering, flowering stage, post-flowering stage. As result highest correlation coefficient found stage vegetation indices values. coefficients are 0.82, 0.80, 0.86, 0.87, respectively. With model, 2019 tried be estimated three different fields. correlations seen pre-flowering NDVI SAVI. This clearly shows that can used remarkable

متن کاملEvaluating the Effect of Different Wheat Rust Disease Symptoms on Vegetation Indices Using Hyperspectral Measurements
Spectral Vegetation Indices (SVIs) have been widely used to indirectly detect plant diseases. The aim of this research is to evaluate the effect of different disease symptoms on SVIs and introduce suitable SVIs to detect rust disease. Wheat leaf rust is one of the prevalent diseases and has different symptoms including yellow, orange, dark brown, and dry areas. The reflectance spectrum data for...
متن کاملMonitoring Winter Wheat Maturity By Hyperspectral Vegetation Indices
It is very important to harvest wheat in optimum time which greatly affects grain quality, mainly referred to as protein content in the research. Because either too early harvest shortens grain-filling process or too late harvest leads to yield losses and poor quality caused by high grain respiration rate in dry and hot wind weather and sprouting in rainy weather. Research was conducted during ...
