The study was conducted at University of Cape Coast Research Farm, Cape Coast, Ghana from February, 2014 to December, 2014. The objective of the research was to investigate the effects of deficit irrigation and chicken manure interactions on the growth and yield of okra. Nine treatments (T1 = 100% CRW, T2 = 90% CWR, T3 = 80% CWR, T4 = 100% CWR+5 t haG1 chicken manure, T5 = 100% CWR+10 t haG1 chicken manure, T6 = 90% CWR+5 t haG1 chicken manure, T7 = 90% CWR+10 t haG1 chicken manure, T8 = 80% CWR+5 t haG1 chicken manure and T9 = 80% CWR+10 t haG1 chicken manure) replicated three (3) times were laid out in a Randomized Complete Block Design (RCBD). The T5 dominated in the growth and yield parameters of okra followed by T4. It was observed that T7 had a comparable yield with full Crop Water Requirements (CWR)+chicken manure (T4 and T5) and 20% deficit irrigation+chicken manure performed poorly (T8 and T9). For efficient water use without any significant yield reduction, 10% deficit irrigation+10 t haG1 chicken is best for okra production.
