Abstract:
Increasing agricultural productivity is essential to meet the challenge of feeding the ever-growing
human population. This systematic literature review explores the use of fertiliser-coated seeds as a
promising method to enhance nutrient use efficiency and crop productivity, particularly in
resource-constrained regions. The study synthesises findings from 24 relevant articles retrieved
from Web of Science and Scopus databases, focusing on seed coating with nutrients. The
analysis of research papers published between 2004 and 2024 reveals an increasing interest in
fertiliser-seed coating technology, with notable contributions coming from China, India, Pakistan
and remains under-researched in Africa. The most commonly utilised nutrients in seed coatings
are zinc (Zn) and phosphorus (P), with Arabic gum serving as a typical binding agent. Despite
the potential benefits, the field remains under-researched, especially regarding the detailed
chemical and mechanical aspects of seed coatings. The findings underscore the need for further
research to develop effective seed coating formulations, use of macronutrients and optimise
their practical application. By improving nutrient uptake and reducing losses, fertiliser-coated
seeds can enhance crop productivity and sustainability, offering a viable solution to the
challenges faced by smallholder farmers in developing countries.
