x>n trial. 
Although the marked variability in cane production in different 
parts of the field made the data inconclusive, the results indicated 
the inferiority of P.O.J. 2878 to B.H. 10(12) in imirrigated gran 
cult ura. The field may be considered as comparable to irrigated 
land, because the rainfall totaled 126 inches (table 3) and was ample 
at all times, except in January 1931. The soil was heavy, varying 
from clay to silty clay loam. Both here and in the variety trial under 
irrigation at Coloso, P.O.J. 2725 compared well with P.O. J. 2878 in 
yields of cane per acre, when - 5.C. 12 4 and P.O.J. 2714 were def- 
initely inferior. The soils were essentially the same in both localities. 
The percentage of sugar in cane of P.O.J. 2878 was markedly superior 
to that of P.O.J. 2725, and this likewise held in the Filial Amor and 
Coloso, 1932, variety trials. Apparently under certain climatic and 
soil conditions P.O.J. 2878 is superior to P.O.J. 2725 in sucrose con- 
tent. Despite unfavorable conditions for ripening, 17.6 inches of 
rain falling during the 2 months preceding harvest (table 3), P.O.J. 
2878 _ ■:. .<• ! high percentage of sugar in cane, and the superiority of 
B.H. 10(12) was due entirely to higher cane production. F.C. 916, 
P.P. 803, and B.H. 10(12) showed only slight differences in sugar 
production. ('«>. 281 ranked first. 
GENERAL FIELD PLAN 1I\<> M.ONC, THE EAST COAST 
The miscellaneous field data of the 1931 32 crops at Fajardo, 
shown in table 4, do not indicate^ any difference in percentage of sugar 
in cane between P.O., J. 2878 and B.H. 10(12).
