The objective of the study is to assess the agronomic and yield characters of sweet sorghum under three different fertilizer treatments such as inorganic, specifically Complete and Urea (120-60-60 of N-P2O5-K2O kg/ha), Vermicompost (1% N), and organic foliar, 'Masinag', (1% N, 2% P, and 2% K2O) in the provinces of Negros Occidental (Sagay City and La Carlota City) and Iloilo (Barotac Viejo) for seed and ratoon crop. Among the fertilizer treatments, inorganic fertilizer proved to be the most effective since it gave higher agronomic, sugar, and yield (stripped stalk, juice and grain) characters across locations. Vermicompost can be an alternative nutrient input because it can enhance the growth and productivity of sweet sorghum specifically in plant height, stalk diameter, sugar content and grain yield. The most suitable location for sweet sorghum production is in LGRTS, La Carlota City, Negros Occidental due to abundant soil nutrients in the area (2.38% OM, 31 ppm P, 192 ppm K) which results to a higher agronomic and yield performance compared to Sagay City and Barotac Viejo. Productivity potential of sweet sorghum can be achieved with proper fertilizer application under suitable environment
