Comparison of Stalk Volume by Water Displacement Method and Calculation Method for Stalk Weight Determination and Its Relevance to Single Cane Weight in Sugarcane Clones

Abstract

The present study was conducted to identify the association of non-destructive rapid estimation of stalk volume by calculation method with water displacement method and to predict the single cane weight by stalk volume. The stalk volume by water displacement method (SVWM) and stalk volume by calculation method (SVCM) were compared for the efficacy of stalk weight determination in sugarcane clones. Results from both methods were similar and a highly significant relationship was found between the two methods (r2 = 0.9092, P 0.88***) with the original single cane weight by both the studied methods, thus, measurements of stalk volume based on calculation method which provide simple, rapid, non-destructive field phenotyping of single cane weight in sugarcane crop may be recommended for the sugarcane research.
