Wheat yield and protein estimation with handheld- and UAV-based reflectance measurements

 Core Ideas

∙ GreenSeeker (GS) and UAV NDVI at Feekes 5 shows the most potential for in-season wheat yield estimation.

∙ Comparable accuracy of yield estimation was achieved with GS NDVI and UAV NDVI.

∙ The accuracy of yield estimation was comparable for all wheat classes and cultivars.

∙ Estimation of in-season wheat protein content remains a challenge.
