SUGARCANE VARIETY P.O.J. 2878 IN PUERTO RICO

Coloso. Practically no replanting was required for P.O.J. 2878, 
whereas the costs of replanting fields of B.H. 10(12) ranged from 
$3 to $4 per acre. Owing in part to more prolific stooling habit, 
fewer stools of P.O.J. 2878 were destroyed during harvesting and 
hauling operations. 
Owing to a combination of its mosaic resistance, prolific stooling 
habit, and ability to withstand drought and overflow, P.O.J. 2878 is 
an excellent ratooner and may be grown for several stubble crops. 
This is generally not true for B.H. 10(12), which dies out during the 
second ratoon at Coloso, and cannot, owing to excessive replanting 
costs, be grown profitably for more than two crops. Even near 
Figure 7.— P.O.J. 2878 is very prolific and makes rapid growth in first ratoons at Julia Farm, Central 
Eureka. This has resulted in low cultivation costs. Four months old when photographed, December 
10, 1930. 
Central Aguirre, a district to which B.H. 10(12) is very well adapted, 
not more than one stubble crop is grown. Hence, in addition to 
increased cultivation and replanting costs, the cost of roguing, and the 
flood risk, the work of frequent land preparation must be charged 
against the cropping of B.H. 10(12). These drawbacks of B.H. 
10(12) tend to offset the profuse arrowing habit and somewhat lower 
percentages of sugar in cane of P.O.J. 2878. 
CULTIVATION COSTS 
Cultivation costs and successful ratooning are influenced by position 
of the leaves, whether erect or spreading; rapidity of growth during 
the first 4 or 5 months, and prolificacy or number of canes per stool. 
In leaf position during the first few months, P.O.J. 2878 has an 
advantage over B.H. 10(12). The prolific stooling and early spread- 
ing growth habit which make possible low cultivation costs with 
P.O.J. 2878 are illustrated in figure 7. The two stools in front had
