Özet
<p><span class="fontstyle0">The purpose of the study was to analyze agricultural drought in citrus areas of Seferihisar Kavakdere Plain by calculating<br>NDVI and SAVI values and the surface temperature. The results showed that NDVI and SAVI have negative correlations<br>with surface temperature during irrigation seasons, where significantly increased temperature and decreased rainfall<br>reduced moisture availability for plants. The correlation coefficients between NDVI and surface temperature are -0.893<br>for 2013 and -0.600 for 2014. The correlation coefficients between SAVI and surface temperature are -0.857 for 2013<br>and -0.783 for 2014. The combination of NDVI, SAVI and surface temperature provides very useful information for<br>agricultural drought monitoring and an early warning system.</span> <br style="font-variant-numeric: normal; font-variant-east-asian: normal; line-height: normal; text-align: -webkit-auto; text-size-adjust: auto;"></p>
