Determination of temporal and spatial changes of NDVI values on wheat planted plots

Abstract

In agricultural production, generally the remote sensing techniques have begun to be used on follow-up of plant development in a widespread manner. Images taken from satellite, airplane and unmanned aerial vehicles provide facilities for the spatial follow-up of the plant's development in the field. For determination of the plant intensity and species, NDVI values is calculated as vegetation index by using images taken in the red and near infrared wavelength reflecting from the plants. In this study, it was aimed to determine the spatial and temporal change of NDVI values in Pehlivan wheat variety planted in farm of Agricultural Faculty, Uludag University during 2015-2016 production period. Landsat 8 images taken at different dates were used in the study. As a result of the plot-based evaluation, the vegetation index values in the parcel did not show a homogeneous distribution.
