Abstract

To explore the effects of pokkah boeng disease (PBD) on sugarcane yield components and provide scientific evidence for the evaluation of production losses, in the present study, plant height, stem diameter, single-stem weight, millable stalks, Brix, yield, and disease index (DSI) of PBD-affected sugarcane during the July–October were investigated. The frequency distribution diagram showed reduction in plant height and stem diameter, i.e., ranging from 10 to 15 cm and 0.05 to 0.06 cm, respectively, and correlation analysis in plant height, stem diameter, single-stem weight, yield, and Brix were significantly negatively correlated with DSI. Furthermore, the yield loss equation (y = 0.738 − 0.971 * x) and Brix loss equation (y = −3.464 − 1.067 * x) were determined using forecast mathematical modeling. In this study, a new method to evaluate the effects of PBD on sugarcane has been reported.
