The study was conducted at University of Cape Coast Research Farm, Cape Coast, Ghana from September, 2014 to January, 2015. The objective of the research was to investigate the effects of irrigation levels, chicken manure, cow dung, NPK and interactions on the: quality and yield of OFSP roots. Sixteen treatments (four levels of irrigation and four soil amendments) with three replicates were laid out in a Randomized Complete Block Design (RCBD). DI (70 % CWR) increased marketable root yield, jumbo root yield and number of roots per plant as compared to full irrigation. On the contrary DI reduced dry matter content. DI did not significantly reduce root decay, root sprouting and root cracking, root damage, weevil infestation and moisture content in the field. Soil amendments did not significantly influence root decay, root sprouting and root cracking, root damage and weevil infestation in the field. PM, CD and NPK significantly increased marketable yields by 40.96 %, 30.34 % and 21.36 % respectively as compared to control.
