A method of evaluating one or more kernels of an ear of maize using digital imagery that includes acquiring a digital image of the one or more kernels of the ear of maize without the use of spatial reference points, processing the digital image to estimate at least one physical property of the one or more kernels of the ear of maize from the digital image, and evaluating the at least one kernel of maize using the estimate of the at least one physical property of the at least one kernel of maize. The method includes using one or more such digital images to estimate yield on a plant, management zone, field, county and country level.

Methods of yield assessment with crop photometry

A method for determining a percent ground cover over an area of land is provided. An image of the area of land is captured, and an area of interest within the image is defined. The area of interest image is converted to a gray scale image, a user-adjustable threshold is specified for distinguishing ground cover from soil and the percent ground cover present in the gray scale image is calculated and reported.
