Revolutionizing Hybrid White Corn Yield: The Synergy of Dolomitic Lime, Magnesium, and Zinc in Asian Productivity

Hybrid white corn has emerged as a strategic staple alternative in Asia, where rising population pressures, soil degradation, and micronutrient deficiencies increasingly threaten food security. Among the constraints, acidic soils dominate vast agricultural landscapes, significantly limiting productivity due to low pH, aluminium toxicity, and nutrient deficiencies, particularly of magnesium (Mg) and zinc (Zn). This review comprehensively examines the synergistic effects of dolomitic lime, Mg, and Zn on the physiological and agronomic performance of hybrid white corn, emphasizing their roles in overcoming soil acidity, enhancing nutrient availability, and optimizing plant function. Dolomitic lime, rich in calcium and magnesium, ameliorates soil acidity while improving nutrient exchange and microbial activity. Magnesium, a central component of chlorophyll and enzyme activator, supports photosynthesis, carbon fixation, and stress resilience. Zinc, vital for protein synthesis, growth regulation, and enzymatic activity, is often deficient in acidic soils but becomes more bioavailable following liming. The integrated application of these amendments significantly improves biomass accumulation, root development, chlorophyll content, and ultimately, grain yield. Field trials across Asia and comparable agroecological zones demonstrate substantial yield gains and improved soil fertility under combined applications. By synthesizing current literature and empirical findings, this review provides actionable insights for nutrient management strategies in acid-prone soils. The synergistic amendment approach presents a scalable, sustainable solution to enhance hybrid white corn productivity and soil health, contributing to food security and agricultural resilience in Asia’s dynamic cropping systems.
