Abstract: Methods for estimating plant age are provided. A first dataset comprising a first plurality of images of a first plurality of plants is obtained, including for each plant of the first plurality of plants, one or more first plant features. A second dataset comprising, for each plant of the first plurality of plants, a respective second plant location and plant age is obtained. The one or more first plant features and plant age for plants in the first plurality of plants are used to train a model for plant age determination. A third dataset comprising a second plurality of images of a second agricultural plot is obtained, including for a second plurality of plants in the second agricultural plot one or more corresponding second plant features. Ages for plants in the second plurality of plants are estimated by inputting one or more respective second plant features into the trained model.
