Pertumbuhan Dan Produksi Jagung Manis (Zea Mays Saccharata Sturt.) Pada Inceptisol Yang Diaplikasikan Biochar Tkks Dan Biostimulan

ABSTRACT
Sweet corn (Zea mays saccharata Sturt.) is an important horticultural crop valued for its sweetness and nutritional composition. Productivity in Riau Province remains below the national average due to the predominance of marginal soils such as Inceptisols, which are characterized by low pH, low base saturation, and limited nutrient availability. Soil fertility improvement has been attempted using biochar derived from oil palm empty fruit bunches (EFB), which enhances soil pH, cation exchange capacity, and nutrient retention. The high C/N ratio of biochar, however, may reduce nitrogen availability, necessitating the use of biostimulants such as amino acids to optimize nutrient uptake and plant performance. This study was conducted from January to April 2025 at the Experimental Farm, Soil Laboratory, and Forestry Laboratory, Faculty of Agriculture, Universitas Riau. A completely randomized factorial design (3 × 3) was applied, consisting of EFB biochar (0, 2.5, and 5 t/ha) and biostimulant (0, 2, and 4 kg/ha), resulting in 27 experimental units. Plant growth parameters and yield components were measured, and data were analyzed using ANOVA followed by Duncan’s Multiple Range Test (α = 5%). No significant interaction between biochar and biostimulant was observed. Significant improvements in soil pH, stem diameter, leaf area, ear length, and yield components were obtained with 2.5 t/ha biochar. Application of 4 kg/ha biostimulant significantly enhanced stem diameter, leaf area, ear length, and yield components. Application of either 2.5 t/ha biochar or 4 kg/ha biostimulant is recommended to improve growth and yield of sweet corn cultivated on Inceptisols.
