Objective:

To evaluate Lentils for yield and agronomic performance in Northwestern Montana. 

Results:

Significant difference was observed for lentil yield with a mean yield of 60.3 bu/A (Table 2) and ranged from 45.9 bu/A for CDC Imigreen to 70.9 bu/A for Avondale. Test weights averaged 62.8 lb/bu. Thousand kernel weights averaged 40.4 grams. Plant stand averaged 10.8 plants per square foot and ranged from 4.6 plnts/sqft for CDC Impala CL to 14.7 plnts/sqft for CDC Imigreen. Days to 50 percent flowering averaged 185 days (July 4). Plant height at flowering averaged 15.9 inches yet no significant difference was observed at physiological maturity.

Summary:

The nursery was planted under rainfed condition with adequate subsurface moisture on silt loam soil. Weed was well controlled this season due to the pre-plant incorporated herbicide.
