4.3 Relationship of yield components
The estimated fiber yield per hectare was computed from the number of harvestable stalks and dry
fiber content. To better understand the relationship of these yield determinants among agronomic and plant
characters, correlation and regression analysis was conducted. The variables used for this analysis were
limited to observations that were independently observed to ensure statistical validity of the results. The
relationship among variables, while they may not be directly useful to the farmers, could be of interest to
abaca researchers.
Number of harvestable stalks
Number of harvestable stalks had positive correlation with number of stalks (r=0.49457) while a
negative correlation was observed with number of leaf sheaths (r=-0.32975), stalk base diameter (r=-0.40368)
and stalk middle diameter (r= -0.2438) (Table 6). This would suggest that as the number of stalks in a
hill increases, the number of harvestable stalks likewise increases. On the other hand, as the stalk girth
increases, the number of harvestable stalks decreases.
