1. Preparation: Please ensure you have a 3×3 foot frame, a white background plate or white paper, and a device to separate the wheat head for photographing.
2. App Setup: Ensure you have internet access to download the app and complete the registration and login process. Internet access is only needed for these initial steps. Once the app is installed, the mobile app and AI algorithms will function without requiring an internet connection.
3. Site Selection: Randomly place the 3×3 foot frame on the field.
4. Field and Site Setup: Use the “Add Field” and “Add Site” icons to set up the field and site where you’ll be taking photos.
5. Counting Total Wheat Heads per 9 sqft: Navigate to the “Heads” tab to take photos of the wheat heads. For optimal accuracy, we recommend taking at least six photos within the frame, ensuring all wheat heads are captured without omission. Our algorithms will automatically aggregate the wheat heads across multiple photos within the frame. Each head should be photographed only once, and any heads outside the frame should be excluded. In future versions, our AI will automatically disregard wheat heads outside the frame.
6. Counting Average Spikelets per Head: Click on the “Spikelets” tab to photograph the wheat heads and calculate the number of spikelets per head. For greater precision, each photo should focus on a single wheat head. To ensure optimal spikelet counting, please capture photos from a lateral view. When photos are taken from a front view, the AI will automatically double the count, assuming the opposite side has an equal number of spikelets. You can click on the spikelet result in the photo to switch between lateral and front view. If multiple photos are taken, our AI will select one to count. This step aims to determine the average number of spikelets per head for the site.
7. Counting Average Seeds per Spikelet: Select one wheat head and count the spikelets. Then, remove the seeds from the spikelets and place them on a white plate or paper. Click on the “Seeds” tab and photograph the seeds. Enter the number of spikelets for that wheat head. This step will help calculate the average number of seeds per spikelet.
8. Calculating Average Yield per Site: Click on the “Yield” tab. The algorithm will automatically display the total number of wheat heads, the average number of seeds per head (seeds per head = spikelets per head * seeds per spikelet), and the average crop yield for the site. Adjusters can manually modify these numbers if needed.
9. Viewing Crop Yield Results: The average crop yield for the entire field, calculated across all sites, will be displayed on the dashboard.

Limitations:

• This version of the mobile app utilizes simple yet effective local AI algorithms. While the app delivers solid performance, integrating advanced AI processing on our servers could boost accuracy by an additional 5-10%. Currently, this version does not support photo uploads to our servers, but this feature will be available in future updates.
• The current AI algorithm has been trained exclusively on data from a single wheat field in Saskatoon. We have not yet incorporated training data from Alberta fields. Once local wheat data from Alberta is included in the training process, accuracy will further improve.
• For optimal spikelet counting, please capture photos from a lateral view.
• For accurate seed counting, ensure the seeds are clean and placed on a white surface, such as paper or a plate.
