Remote Sensors to Estimate Winter Wheat Growth.

Measuring crop growth by destructing methods is tedious and the error inherent with the method is high due to sampling. Experimental wheat plots do not allow big samples, which are often not as homogeneous as it would be needed. Sensors like GreenSeeker, that measures the NDVI index and digital photography are non-destructive methods that have been used to estimate biomass in several crops, including wheat. We intend to use those methods to estimate the growth of 24 winter wheat varieties taking several measurements throughout the growing season in addition to biomass samples to calibrate them. We will be discussing the results from the technological point of view.
