Abstract
Waxy corn (Zea mays ceratina) is a corn variety with high amylopectin content and significant economic value but suffers from low productivity due to inadequate cultivation practices and nutrient deficiencies, particularly in zinc (Zn) and potassium (K). This study aimed to evaluate the effects of Zn seed priming concentrations and potassium chloride (KCl) fertilizer dosages on the growth, yield, and grain quality of waxy corn. The research was conducted from February to April 2025 in Surabaya, using a factorial randomized block design with two factors: three Zn seed priming concentrations (0 g/L, 0.5 g/L, and 1 g/L) and four KCl fertilizer dosages (50, 100, 150, and 200 kg/ha). Results revealed that the combination of Zn 1 g/L and KCl 100 kg/ha produced the highest ear weight, Zn content (23.65 ppm), and dehusked ear weight per plant (258.57 g). Meanwhile, the combination of Zn 0.5 g/L and KCl 100 kg/ha resulted in the best grain quality, with the highest amylopectin (98.73%) and lowest amylose (1.27%) contents. Potassium fertilizer at 200 kg/ha also significantly improved plant height, leaf number, and ear diameter. Therefore, Zn 1 g/L and KCl 100 kg/ha are recommended for yield and biofortification purposes, while Zn 0.5 g/L and KCl 100 kg/ha is more suitable for grain quality and fertilization efficiency. This study offers an alternative strategy for sustainable and nutrient-rich waxy corn cultivation.
