| Abstract |
Background and Objective: One strategy to improve sugarcane yield is understanding the optimization of the photosynthetic organs, such as leaf area, to accelerate ground and canopy cover. Non-destructive sampling through image analysis, using a high-angle image as a simple method, could represent the percentage of ground cover. Therefore, the purpose of this study was to evaluate ground cover using high-angle images of diverse sugarcane cultivars and their relationship with destructively sampled growth. Materials and Methods: A randomized complete block (RCB) design with four replications was used. Five commercial sugarcane cultivars with different canopy types were assigned as treatments. Destructive growth samples were collected at 30-day intervals from 30 to 120 days after transplanting (DAP). Image analysis for ground cover using Gimp 2.20.12 software, and non-destructive growth samples were measured at 15-day intervals from 30 to 120 DAP. Results: The five cultivars in this study had different ground covering speeds. Cultivar ‘KPS01-12’ was identified as the fastest ground-covering cultivar, and ‘UT-13’ had moderate ground coverage, whereas UT-12 and ‘KK3’ were slower ground-covering cultivars. The fastest ground-covering cultivar, ‘KPS01-12’, also revealed outstandingly high measurements during destructive growth sampling, namely Leaf area index (LAI), leaf area (LA), leaf dry weight, stalk dry weight and biomass. Correlation between ground cover, LAI, and leaf dry weight existed at 90 and 120 DAP in diverse sugarcane cultivars, but not 30 and 60 DAP. Conclusion: The ground coverage measurement using a high-angle image is a feasible indirect measurement of growth traits that would have to be measured destructively at some developmental stages. This information would help support further sugarcane research as a non-destructive criterion in several aspects. |
