For cherries, payback is not normally just measured in yield, earliness or class one percentage gain, but often on the removal of risk. Commonly payback can be achieved in one day through the removal of a catastrophic event such as cracking caused by rain or frost at flowering.
The following chart highlights the impact of the Haygrove Tunnels on an orchard in Pennsylvania where severe rains devastated a ripening crop of Rainier cherries.
| Haygrove Tunnel | Outdoors | % Difference | |
|---|---|---|---|
| Total yield/ha (ac) | 14.2T/ha (5.82t/ac) | 11.4T/ha (4.67t/ac) | +25% |
| Class 1 % | 98% | 26% | |
| Total Class One Yield per ha (acre) | 14.2T/ha (5.82t/ac) | 2.87T/ha (1.17t/ac) | +397% |
| Event | Very heavy rain event when the fruit was ripening causing severe cracking | ||
