Production of eggplant as affected by the application of varying levels of sugarcane filter cake combined with fixed amount of inorganic fertilizer
Abstract
Food security remains a critical concern in the Philippines, especially amid challenges such as rapid population growth, climate change, and high agricultural input costs. This study evaluated the effects of sugarcane filter cake, an organic by-product of the sugar industry, on the growth and yield of eggplant (Solanum melongena L.) under varying application levels combined with recommended rates of inorganic fertilizer. Conducted at the Cagayan State University Integrated Farm from January to April 2025, the field experiment employed a Randomized Complete Block Design (RCBD) with six treatment combinations. Results revealed that the combination of recommended inorganic fertilizer and 2 tons/ha of sugarcane filter cake (Treatment 4) produced the most favorable outcomes across several parameters, including plant height, number of fruits per plant, fruit weight, and overall yield (16.9 tons/ha). Statistical analyses indicated significant differences among treatments, highlighting the synergistic effect of combining organic and inorganic fertilizers. These findings support the potential of sugarcane filter cake as a sustainable soil amendment that enhances eggplant productivity while addressing environmental and economic challenges in agriculture. The study aligns with Sustainable Development Goals (SDGs) on zero hunger, responsible production, and land biodiversity.
