Abstract

This study aimed to determine the most effective NPK fertilizer dosage for the growth and yield of several F15 maize genotypes on peat soil. The experiment was conducted in Bansir Darat Subdistrict, Southeast Pontianak District, Pontianak City, from June 4 to November 4, 2024. A Split Plot Design was used, with the main plots consisting of F15 maize genotypes (A = F15-1-Bm-2-3-Az-1, B = F15-1-Cm-2-3-Az-1, C = F15-1-Dm-2-3-Az-1) and subplots consisting of NPK Phonska 15:15:15 fertilizer dosages (M1 = 350 kg/ha, M2 = 400 kg/ha, M3 = 450 kg/ha, M4 = 500 kg/ha). A total of 12 treatment combinations were repeated 3 times, resulting in 36 experimental units and 108 sample plants. Observed variables included plant height, number of leaves, days to tasseling, days to silking, physiological maturity, ear height, ear weight (with and without husk), ear length, number of rows per ear, ear circumference, dry kernel weight per ear, and 1000-grain weight. Results showed that genotype significantly affected days to tasseling, days to silking, and ear circumference. NPK fertilizer dosage had a significant effect on plant height, ear height, ear length, ear circumference, number of rows per ear, ear weight (with and without husk), dry kernel weight per ear, and 1000-grain weight. The NPK dosage of 400 kg/ha (9.5 g/polybag) was found to be the most efficient for supporting the growth and yield of F15 maize on peat soil.
