BULLETIN 1309, U. S. DEPARTMENT OF AGRICULTURE 
Table 8 shows that Purplestraw produced a higher yield from the 
8-peck than from the lower rates in three of the five years; but the 
5-year net average shows no gain over the 6-peck rate, and Fultz 
shows little gain from seeding more than 4 pecks. Dietz produced a 
6-year average yield of 26.9 bushels from the 8-peck rate, 0.3 bushel 
in excess of the next highest yield, but Stoner in the same period 
showed a net loss of 1.9 bushels from sowing 8 pecks as compared 
with the 6-peck rate from which the highest average yield was 
obtained.
