Impact of zinc foliar spray on maize (Zea mays L.) growth, yield and nutrient uptake

Abstract

Foliar application of zinc, which involves directly spraying solutions containing zinc onto the leaves to facilitate quick absorption and use by the plant, is an efficient way to correct zinc deficiency in maize (Zea mays L.). When applied in situations where soil-based zinc treatments are less successful because of things like high pH or calcareous soils, this approach has been demonstrated to dramatically improve maize growth, yield, and nutritional quality. Chlorophyll production depends on zinc, and zinc applied topically can increase the amount of chlorophyll, enhancing photosynthesis and producing healthier, greener plants. An agronomic technique that is very successful in improving maize's growth traits, yield, and nutrient quality is applying zinc foliarly. By addressing zinc deficiency in this way, food security is increased, sustainable agricultural practices are supported, and maize cultivation growth is economically boosted. The long-term viability and success of maize farming depend on these approaches being optimized through more study and field testing.
