Seed Treatment Assessment
Seed treatment’s application is to optimize seed performance, cost-effectiveness and yield of the crop.
Seed treatment examples are:
How to Design a Seed Coating Recipe for a Given Polymer and a Given Crop?
Before you can create a recipe you need to prepare and image at least two samples for seed treatment:
• A control sample of untreated seeds
• A reference sample of “ideally” coated seeds
These samples are shown.
Then, from the two images a machine learning algorithm will learn a loading mapping (image on the right).
This loading map shows the loading in every pixel of the image. Average loading and heterogeneity (Coefficient of variation, CV) can now be calculated for each sample.
Results of the seed coating recipe are shown below. The loading map, average loading, and loading heterogeneity obtained directly from the recipe is shown on the top left. In addition, bottom left figure shows the relation between optical loading and amount of polymer. Hence, this can be used as a calibration curve between the two.
Bottom right figure shows the loading heterogeneity in the coating array. We see that increasing amount of coating liquid decreases heterogeneity. Moreover, is it also visible that the optimal concentration for low heterogeneity varies with the amount of coating liquid. 50% concentration is the worst at 10 ml of coating liquid but the best at 50 ml
