As we transition from nut fill to pre-harvest operations, it's crucial to adapt irrigation strategies to the unique conditions of the 2024 almond growing season. In this edition of AlmondBeat, we provide expert insights on leveraging Phytech for regulated deficit irrigation (RDI) to optimize this year’s upcoming harvest.

Tailoring Regulated Deficit Irrigation (RDI) for Your Needs
Given the drier conditions this season, a less aggressive deficit strategy compared to last year might be beneficial and locations that are already experiencing significant stress should avoid RDI. Key indicators and recommendations include:
Monitoring Plant Growth: As nut fill concludes, growth should plateau (use season view on the overview), signaling it's time to commence RDI. Utilize Phytech's data to track plant status and adjust irrigation levels accordingly. Aim for multiple yellow plant statuses for a balanced deficit, or target orange for a more intensive approach.
Understanding Plant Stress: Some stress during this period is normal and even beneficial. However, avoid excessive stress levels (no more than two consecutive red days) to prevent defoliation and ensure the tree's health for the next season.
2 Common Deficit Practices
Key Takeaways for the Season
Plant Status: Manage stress carefully. Acceptable stress levels during the post-nut fill phase are indicated by yellow statuses. Avoid prolonged periods of severe stress to protect tree health and the next season's yield.
Plant Growth: Growth should plateau post-nut fill. If growth continues, it may indicate a lower-than-normal crop load, necessitating irrigation adjustments.
Regulated Deficit: Begin RDI now, maintaining slight stress to conserve water, reduce humidity-related fungal diseases, and ensure uniform hull split. Phytech’s plant status monitoring allows for precise irrigation adjustments.
By strategically implementing these practices and leveraging Phytech's advanced monitoring capabilities, you can navigate the challenges of the remaining 2024 almond growing season with confidence.
