Abstract
Abstract Anoxia is a major problem in waterlogged soil, and most crop plants suffer reduced growth and yield from it. Inorganic peroxides react with water and evolve oxygen, so peroxide seed coatings could supply oxygen to seeds and seedlings. Three greenhouse experiments tested the ability of peroxide seed coatings to improve emergence in flooded soil. Maize ( Zea mays L.), soybean [ Glycine max (L.) Merr.], wheat ( Triticum aestivum L.), and barley ( Hordeum vulgare L.) were grown in Piano silt loam soil (fine‐silty, mixed, mesic, Typic Argiudoll) in plastic trays. Soil moisture treatments included normal moisture and flooding for three days after planting. Calcium peroxide, zinc peroxide, and a formulation containing calcium peroxide were applied as seed coatings at rates of 12 and 25% wt/wt seed. The most significant effect of the peroxides was on percent emergence, and wheat showed the most favorable results. Calcium and zinc peroxides at 25% improved wheat emergence by an average of 42% in flooded treatments in two experiments. Zinc peroxide at 25% improved wheat emergence by 21% in the third experiment. Zinc peroxide at 25% significantly improved corn emergence with flooding in one experiment. Soybean emergence in flooded soil was improved slightly by zinc peroxide, and was decreased by calcium peroxide. Barley emergence was not affected by peroxide. Peroxides generally had no effect on emergence with normal soil moisture. Time to emergence, plant height, and plant dry matter were not affected by peroxide seed coatings. Peroxide seed coatings had variable effects on plant emergence, and wheat showed the most consistent positive response.
