Experiments were carried out at National Horticulture Research Institute, Ibadan, between November 2008 and august 2009 to evaluate the effects of organic amendment on growth and flower yield of sunflower. The treatments consisted of curved poultry manure (PM), cow dung (CD) and composted organic waste of different combination on dry weight basis: cassava/poutry manure 3:1 (Cp3pm),cassava/poutry manure 2:1 (Cp2pm),elephant grass/poutry manure (Eg3pm), and elephant grass/poutry manure (Eg2pm) and top soil a control. Organic amendments at 5 ton ha (15.8g) were added to pots containing 6kg top soil. The experiments were arranged in a completely randomized design (CRD) and replicated three times. Data on growth parameters (number of leaves, stem girth and plant height) were collected at 2 weeks interval from four (4) weeks after planting (WAP). Yield dat were also collected at 2 weeks indicated that Cp3pm significantly recorded higher plant height at 4 WAP, but significantly had lowest stem and root dry matter weight. However, cow dung (CD) significantly produced higher flower diameter (12.13 cm) at anthesis and head weight (39.3g) at maturity.
