Barchet kaoliang is fairly early ia maturing. The data cover only 

 eight years, the record of 1909 being 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 growing 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 kaoHang is 4.3 feet under the 

 conditions obtaining at Amarillo in the last nine years. The lowest 

 stature in any year in which grain matured was 3 feet, in 1916. The 

 taUest growth was made in 1911 and 1915, when its height was 5.3 

 feet.

a Average of three plats. 



The annual and average acre yields of Barchet kaohang in the 9-year 

 period are shown in Table XXXIII, compared with those of White 

 kaohang. 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 httle lower than those 

 of White durra and Dawn kafir, and is better than those of either 

 Blackhull or Red kafir. Barchet kaohang was able to make a smaU
