Use of plant indices in early yield estimation for winter wheat
Öz
The study was carried out in İkizce Research Farm of Field Crops Central Research Institute in 2014 and 2015 . The experiment was established according to random blocks experimental design with three replicates and 0, 4, 8, 12 and 16 kg/da nitrogen applications were made. Normalized difference vegetation index (NDVI) readings were taken with a portable handheld GreenSeeker device throughout the growing season. Spectroradiometer readings were taken in each plot from sowing to harvest. In addition, the relationships between biophysical characteristics of the plant and yield values were determined. The measured spectroradiometer values were used to calculate various plant indices reported in the literature. Considering the phenological development periods between 2013 and 2014 in Haymana, the correlation values between grain yield and spectral indices (r² <0,277) in the early period (Feekes 1-9) from emergence to stalk emergence were lower than the values (r² <0,603) in the late period (Feekes 10-11,4). The correlation values of the first ten indices (SR-5, SR-8, NDI-2, OVI, SR-2, SR-17, NDVI-3, SR-10, NDI-1, NVI) in the late development period (flowering) ranged between R²=0.453-0.603 and Green + Red + Red Border + Near Infra-Red (NIR) bands were prominent. The highest correlations between grain yield and spectral indices were determined at the beginning of flowering (26 May 2015) and correlation values ranged between R²= 0.930-0.889 for the first ten indices for 2014-2015 growing season. The prominent indices in this period were NVI, SR-8, SR-11, SR-5, SR-17, OVI, SR-2, SR-1, ZTM, SR-16, respectively. These indices were in located in the 550-900 nm band range, in the green+red+red+red edge (Red Edge) + Near Infrared (NIR) range on the electromagnetic spectrum. The use of spectral data in early yield estimation in wheat is important in terms of guiding national agricultural policies. The application and dissemination of this estimation method in yield estimations in different locations in the future will provide great convenience.
