Barchet kaoliang is fairly early m maturing. The data cover only 
eight years, the record of 1909 beimg incomplete. The average 
duration of the vegetative period is 76.5 days, of the fruiting period 
30.5 days, and of the entire growing period only 107 days. This 
period is of about the same length as that of milo and Dwarf milo, 
but is more than two weeks shorter than that of even the earliest 
kafir. The shortest growmg period recorded is 96 days, in 1914, 
when the duration of the vegetative period was only 71 days and the 
fruiting period only 25 days. In that year, however, only the earliest 
heads appeared. The longest growing period recorded is 124 days, 
in 1916, when the vegetative period occupied only 77 days, but the 
fruiting period was prolonged by drought to 47 days, the longest 
yet recorded for this variety. The shortest fruiting period was 21 
days, in 1910, correlated, however, with the longest vegetative period, 
or 90 days. The shortest vegetative period was 65 days, in 1915, a 
year of abundant moisture, in which this variety ripened in 103 days, 
while most of the grain sorghums required more than their average 
time in which to mature. 
The average height of the Barchet kaoliang 1 is 4, 3 feet under the 
conditions obtainmg at Amarillo in the last nine years. The lowest 
stature in any year in which grain matured was 3 feet, in 1916. The 
tallest growth was made in 1911 and 1915, pon its eens was 5. 3 
feet.

The annual and average acre yields of Barchet kaoliang in the 9-year 
period are shown in Table XX XIII, compared with those of White 
kaoliang. The 9-year average yield has been 18 bushels, based on 
the records of 16 plats. This average yield is from 4 to 10 bushels 
lower than those of the milos and feterita, is a little lower than those 
of White durra and Dawn kafir, and is better than those of either 
Blackhull or Red kafir. Barchet kaoliang was able to make a small
