The severity of crop damage by hail is frequently estimated using equations derived from controlled experiments, but this approach has not been extended to the indeterminate pulse crop lentil (Lens culinaris L.). The objective was to simulate hail damage on two lentil cultivars, and estimate yield reduction for use in the Crop Insurance Industry. Hail damage was simulated by controlled canopy crushing on two cultivars, CDC Blaze and CDC Sedley at 4 location-years in Saskatchewan in 2006 and 2007. Plots received simulated damage as the untreated control (0%), 30, 60 or 90% canopy height reduction by crushing at each of four growth stages: vegetative, early flowering, pod-filling, and physiological maturity. As damage intensity increased from 0 to 90%, yield decreased in both cultivars. Most yield reduction (>65%) was seen when damage occurred in reproductive growth. Yield reduction for lentil damaged in vegetative growth was described by linear models, and the reproductive stages by quadratic models. The equations will help improve hail damage assessment in lentil on the Northern Great Plains.
