The synergy between zinc and vitamins promotes corn growth and yield

Abstract Using zinc and vitamins can help improve the physiological conditions of corn ( Zea mays L.), providing better vegetative and reproductive development. Because of their potential for use in agriculture, an attempt is being made to establish the most efficient utilization. This study evaluated the effects of zinc, nicotinamide, and pyridoxine on second crop corn growth characteristics, grain yield, and its components. Two field experiments were conducted in a randomized block design in two locations, with nine treatments and four replications. In both experiments, the treatments were T1: control, T2: Zn 0.5%, T3: Zn 1%, T4: nicotinamide 200 mg L − 1 , T5: pyridoxine 200 mg L − 1 , T6: Zn 0.5 + nicotinamide 200 mg L − 1 , T7: Zn 1% + nicotinamide 200 mg L − 1 , T8: Zn 0.5% + pyridoxine 200 mg L − 1 , and T9: Zn 1% + pyridoxine 200 mg L − 1 , applied via foliar. Growth characteristics, grain yield, and its components were evaluated. The use of nicotinamide combined with zinc was found to have a positive influence on the characteristics evaluated. It can, therefore, be concluded that applying zinc and the vitamins nicotinamide and pyridoxine is beneficial for growing corn, improving plant development and yield characteristics. In addition, the interaction between zinc and vitamins results in a synergistic effect, compared to applying each product alone, with the combination of 1.0% zinc and nicotinamide standing out.
