The yields in some years were reduced by hail, but they were fairly

Northwestern and Payne White are two of the earliest dent 
varieties included in the experiments. Both mature at about the 
same time and matured fully ripe corn every year in which a crop 
was produced. The Payne White outyielded Northwestern each 
year. 
Selection No. 133 and Minnesota No. 13 are representatives of 
later and larger growing varieties. At this station these varieties 
have not averaged larger grain yields than the smaller growing earlier 
varieties, but they have produced larger total yields of fodder. 
They matured in only three of the six years in which a crop was 
produced, and the ears were soft. In 1920 both varieties were frosted 
while in the milk stage, and in 1922 and 1923 the corn was soft when 
harvested early enough to prevent a loss of the fodder by drying up. 
Probabl.y as great a crop of total feed has been produced from the 
early-maturing varieties as from the later ones. 
The early flint varieties, such as Gehu and Dakota White, have 
produced as large yields of grain as have been secured. These 
varieties are difficult to harvest \^-ith a com binder but are valuable 
for hogging off. Assinniboine ffint has not yielded quite as well but 
is several days earlier, being the earliest variety that has been tested. 
Several varieties procured locally were planted in 1923. Some of 
these outyielded the early varieties shown in the table, their maturity
