A review of literature was conducted on how growth, yield and quality respond to plant spacing in Irish potato. A number of parameters were considered: stem length, stem number, tuber numbers, tuber size categories, total yield, marketable yield, dry matter content and specific gravity. Some contradictions were exposed showing the need for further researches concerning how spacing interacts with the environment and other production practices including varietal choices. This information will help producers to optimise productivity.
Key words: Plant spacing, potato growth, potato yield, potato quality.
