Abstract

Sweet sorghum stems contain sap rich in lignocellulose and saccharides, making the plant a valuable source of high-quality forage, ethanol, and food products. This study aimed to investigate the effects of biochar application and shoot number manipulation on the growth response and sugar content of stem sap in first ratoon sweet sorghum. A Completely Randomized Block Design (CRBD) was employed, and data were subjected to an analysis of variance (ANOVA) at a 95% confidence level. In cases of significant differences, Duncan's Multiple Range Test (DMRT) was conducted for post-hoc comparisons. Results demonstrated a significant interaction between biochar application and shoot number manipulation on sugar content in the stem sap. Biochar application had a non-significant effect on the number of leaves and leaf area index, while shoot number manipulation exhibited a non-significant influence on stem diameter and seed weight per plant. These findings contribute to the understanding of optimizing growth and sugar accumulation in first ratoon sweet sorghum, potentially enhancing its applications in forage, ethanol, and food industries.
