Micronutrients are vital for plant growth and human health. Soil and foliar
applications are the most prevalent methods of micronutrient addition but the cost
involved and difficulty in obtaining high quality micronutrient fertilizers are major
concerns with these in developing countries. Micronutrient seed treatments,
which include seed priming and seed coating, are an attractive and easy alternative.
Here in this review, we discuss the potential of micronutrient seed treatments for
improving crop growth and grain nutrient enrichment. Micronutrient application
through seed treatments improves the stand establishment, advances phenological
events, and increases yield and micronutrient grain contents in most cases. In some
instances, seed treatments are not beneficial; however, the negative effects are rare.
In most cases, micronutrient application through seed treatment performed better
or similar to other application methods. Being an easy and cost effective method of
micronutrient application, seed treatments offer an attractive option for resourcepoor
farmers
