Objective:

To evaluate Lentil cultivars for yield and agronomic performance in Northwestern Montana.

Results:

Significant difference was observed for lentil yield. Average yield was 48.3 bu/A (Table 2) and ranged from 36.9 bu/A for CDC Imigreen to 55.3 bu/A for Eagle. Test weights averaged 63.3 lb/bu. Thousand kernel weights were significant with an average of 38.3 grams. Statistical differences were observed for height at pod fill, with an average of 14.8 inches. No significant differences were observed for heights at flowering or at physiological maturity.

Summary:

The nursery was planted under rainfed condition with adequate moisture. This trial faced weed interference despite the use of Dimetric.
