Abstract
The study evaluated the response of waxy-sweet white corn (Zea mays L. var. 'Sweet Pearl F1') to different concentrations of Sargassum spp.-based concoction as a biofertilizer alternative to inorganic fertilizers. This was conducted using a Randomized Complete Block Design (RCBD) with five treatments replicated three times, the study assessed growth parameters, yield components, and economic viability. Results indicated that Sargassum spp.-based concoction (SBC) significantly influenced plant height, leaf count, stem diameter, and yield-related parameters, including ear length, ear diameter, and number of kernels per ear. Among the different SBC concentrations, 500 L/ha and 750 L/ha produced results comparable to the recommended rate of inorganic fertilizer (RRIF), particularly in yield and sugar content (brix°). Economic analysis demonstrated that Sargassum spp.-based biofertilizer improved net income and return per cost, highlighting its potential as an environmentally sustainable alternative to synthetic fertilizers. These findings suggest that integrating macroalgae-based fertilizers into sweet corn cultivation can enhance production while minimizing chemical inputs, contributing to sustainable agriculture.
