1 Dates shown are average dates of first, second, third, and fourth seedings, respectively. 
- Yields from first seeding used for both first and second dates. 
3 Yield supplied by using average of first and third dates. 
* Yield supplied by using that of third date. 
In other experiments at the Ontario Agricultural College, Guelph, 
Ontario, Vernal (White Spring) emmer and Red spelt were sown on 
eight dates each spring during a 5-year period. The first sowings 
were made at the earliest possible date each year and later sowings 
each succeeding week thereafter. The average data for five years 
are shown in Table 55. The results show that the highest average 
yields of emmer were obtained from the second sowing, but that only 
slight differences exist between the results from the first four sowings. 
The later sowings, however, yielded progressively less. The earliest 
sowing of Red spelt produced the highest yield, with marked decreases 
from all later sowings. As mentioned in the description of Red 
spelt, this variety usually is grown as a winter crop in the United 
States. It will mature seed from spring sowing and, if sown early, 
as here shown, will produce good yields. Its late maturity, together 
with the winter or intermediate habit of growth, make it an unsatis- 
factory spring crop in most sections.
