Decline in fiber yield and tensile strength of abaca due to mosaic and cost-returns analysis under varying disease-influenced production scenarios

Abstract

Severity level of abaca mosaic significantly reduced the tensile strength, biomass yield, fiber yield, plant height, and stalk diameter of abaca at all stages of plant growth. Relationship between disease severity and tensile strength, total fiber yield, plant height, steam diameter, and total gross income were described by the following equations: Y = 33.02 - 2.30X, Y = 414.31 - 47.52X = 13.71 - 0.489X, Y = 587.28 - 28.81X, Y = 52.58 - 4.16X, and Y = 15703 - 2120.02X, respectively. R² values for all the parameters regressed were highly significant. Abaca mosaic severity level significantly reduced the gross income of farmer wherein total gross income decreased with increasing disease intensity. An estimated per hectare annual loss of the Php 26,184.06 when extrapolated to a regional annual loss would be catastrophic if abaca mosaic severity would reach level 5.
