Rain during the critical flowering period reduced pollination and limited apricot yield during the 2026 Armenian season. However, the completed EcoRic field trial produced encouraging results in fruit quality, with clean, firm apricots and minimal visible rot or spotting.
Apricot production is closely linked with Armenian agriculture, but the crop can be highly sensitive to weather during flowering.
The completed 2026 EcoRic field trial demonstrated this clearly. The tested apricot trees entered spring with strong flowering. However, rainfall occurred during the main pollination period, significantly reducing bee activity. As a result, fruit set was lower than expected and the final crop was smaller than in the previous season. At the same time, an important second result emerged: the fruit that successfully developed was of high visual quality.
Trial Conditions
The apricot trial followed conditions comparable to those observed in the plum trial conducted during the same season. Flowering itself was good. The major limitation developed during pollination. Rain prevented normal bee activity, meaning that part of the potential crop was lost before fruit development began. This distinction is essential when evaluating the performance of an agricultural treatment.
EcoRic cannot compensate for flowers that were not pollinated. Therefore, the reduced yield should not be attributed directly to the treatment programme. Instead, the condition of successfully developed fruit provides the more useful agronomic indicator.
Results at Harvest
The harvested apricots were observed to have:
- clean external surfaces
- good fruit firmness
- very limited visible spotting
- low levels of visible rot
- healthy appearance
- good commercial presentation
For an apricot grower, these parameters are important because the crop is relatively delicate and damaged fruit can deteriorate rapidly. A harvest containing a greater percentage of clean, undamaged fruit creates a larger marketable crop even when total biological yield is constrained by seasonal conditions.
Why a Wet Flowering Period Matters
Rain during flowering creates two different challenges.
The first is physical: pollinator activity decreases.
The second is phytosanitary: prolonged moisture can increase the risk of infection of flowers, young tissues and developing fruit.
This means that an apricot orchard may experience lower fruit set and higher disease pressure during the same period.
The 2026 season therefore represented a useful test of crop quality under challenging conditions. Despite the weather, the fruit reaching harvest remained largely clean and healthy.
Evaluating EcoRic Correctly
The field observations suggest a positive outcome for fruit quality, but they should be interpreted within the limits of the trial. The trial did not include sufficient replicated quantitative data to claim a precise percentage reduction in disease. It is more accurate to conclude that:
- rainy flowering conditions reduced pollination
- the resulting crop was smaller than the previous year's
- fruit reaching harvest showed good firmness
- visible rot and spotting were limited
- overall commercial appearance was good
These observations provide a basis for a larger controlled trial.
What Should Be Measured in the Next Apricot Trial?
For future programmes, agronomists should evaluate the crop from flowering through harvest.
Recommended parameters include:
During flowering
- percentage flowering
- rainfall
- temperature
- bee activity
- duration of wet conditions
After flowering
- fruit-set percentage
- flower and shoot dieback
- young-fruit damage
During fruit development
- disease incidence
- surface spotting
- shoot condition
- canopy health
At harvest
- kg per tree
- tonnes per hectare
- average fruit weight
- fruit diameter
- percentage of healthy fruit
- percentage affected by rot
- marketable yield
Marketable Yield Matters
A high yield does not automatically mean a profitable harvest. Fruit affected by rot, severe skin damage or other visible defects may not meet fresh-market specifications.
For this reason, future EcoRic trials should evaluate: total yield and marketable yield separately.
This approach provides farmers with a much more meaningful commercial measurement.
Conclusion
The completed 2026 EcoRic apricot trial in Armenia took place during a difficult flowering season in which rainfall significantly restricted pollinator activity.
The resulting crop was smaller than in 2025.
However, the fruit that successfully developed remained clean, firm and largely free from visible rot and spotting.
The result provides a strong reason to continue controlled EcoRic trials on apricot, particularly with detailed measurements of disease incidence and marketable yield.
