Abstract
Many soils in the high rainfall sub-tropics are deficient in micronutrients, especially zinc (Zn), boron (B), and molybdenum (Mo). In vivo micronutrient enrichment of seed via foliar applications of micronutrients on the mother plants was evaluated as a strategy to address soil micronutrient deficiencies because farmers have limited access to soil testing for micronutrients. Seed enrichment was expected to alleviate soil deficiencies and to provide resistance against seedling root diseases. Fertiliser salts of Zn, Mo, nickel (Ni), copper (Cu), manganese (Mn), and boron (B) were sprayed at recommended concentrations five or ten times during the growth stages of wheat and rice, respectively. Both wheat and rice seed were enriched with all micronutrients, except B. Wheat seedling emergence and vigour were enhanced with seed enriched with micronutrients compared to unenriched seed. We believe this is due to increased resistance to soil borne pathogens. Wheat and rice seeds enriched with micronutrients that were sown in farmers’ fields had increased yields relative to unenriched control seeds. Wheat yields increased an average of 25% in twelve of forty-seven on-farm trials in northwest Bangladesh. Rice yields increased an average of 22% in twelve of seventeen on-farm trials in the same area. Results indicate that seed enriched with micronutrients could improve yields of both wheat and rice in areas with micronutrient deficient soils without soil testing.
