SWEET CLOVER, WHITE ANNUAL 
833 
a cultivated field as in such a situation it 
would have been lost. It evidently grew 
on wild land for several years without any¬ 
one noticing that it was an annual. Re¬ 
cently it has been definitely established 
that it is still found on waste land in Ala¬ 
bama. Considerable sweet clover seed is 
harvested in certain sections of the State 
by negroes, who either strip the seed from 
the plants or cut them down and thresh the 
seed out by hand. Thus the seed of the 
two clovers might easily become mixed. Its 
subsequent discovery in an 
Iowa greenhouse was a for¬ 
tunate event, which bids fair 
to be of untold benefit to both 
farmers and beekeepers. 
In the spring of 1918, 100 
seeds were sent by Prof. 
Hughes to each of the State 
experiment stations, and 50 
to each seed company in the 
United States. Small samples 
were also sent to fanners and 
seed-growers in different 
parts of the world for trial. 
Probably no other new plant 
ever was so widely distributed 
in so short a time. Altho large 
sums were offered for sam¬ 
ples of the seed none was sold. 
The newly discovered plant 
was fully and freely given to 
the world. In the spring of 
1920, 47,000 samples of seed 
were distributed by the Iowa 
station. 
Reports from nearly all 
parts of the United States 
show that annual sweet clo¬ 
ver can be successfully grown 
over a very wide area, and un¬ 
der varied climatic conditions. 
In Iowa, at Ames, the plants 
have often averaged a growth 
of over 1% inches per day with a maximum, 
under greenhouse conditions, of 2% inches 
in 15 hours. Spikes of seed, which measured 
20 inches in length, have been produced. 
Planted in rows 3 feet apart the yield of 
seed was from 5 to 8 bushels per acre. 
When seeded broadcast on a weedy and 
poorly prepared seed bed the last of May, 
it overcame the weeds, made a growth of 
5 V2 to 7 feet, and matured a seed crop. In- 
27” 
dividual plants in this State have attained 
a height of 9 to 10 feet. In Mississippi 
seed was sown in the fall and the young 
plants survived the winter, and by May 15 
were large enough to plough under as a 
soil-fertilizer. Seed grown in the spring 
matured a crop by July 10. Seed planted in 
April in another locality in this State was 
7 feet tall in 4^2 months. Equally favor¬ 
able reports have been received from Ohio, 
Maryland, Kentucky, California, Oregon, 
and many other States. In the island of 
Hawaii two crops have been grown in a 
single season—the second crop coming 
from seed produced by the first crop. The 
first averaged 5 feet in height, and the sec¬ 
ond 4^/2 feet and remained in bloom for 
nearly 7 weeks. 
The new Hubam variety of clover fills a 
place which no other legume occupies. No 
other leguminous plant will so quickly fur¬ 
nish the farmer with hay and pasturage 
Nos. 1 and 2—Hubam and the annual yellow sweet clover 
planted the same day, cultivated and raised in the same row 
and under identical conditions. Nos. 3 and 4—Hubam and the 
old biennial sweet clover planted the same day, cultivated and 
raised in the same row and under identical conditions.
