This research evaluated the effect of seed rate, sowing method and poultry manureon growth and yield of finger millet (Eleusine coracana (L.) Gaertn). The trials were conducted in the 2013 and 2014 wet seasons, at the Institute for Agricultural Research, Samaru in the Northern Guinea savanna agro-ecology of Nigeria. Treatments consisted of two sowing methods (broadcast, dibbling), three seed rates (3, 6, 9 kg ha-1) and poultry manure (0, 2.5, 5.0 t ha-1) NPK (90 kg N + 60 kgP205 + 60 kg K20 ha-1). The experiments were laid out in a split plot design using three replications. A factorial combination of sowing method, poultry manure and NPK constituted the main plots, while seed rate constituted the subplots. The lower seed rate of 3 kg seed ha-1 produced significantly (p<0.05) higher leaf area plant-1but distinctly gave lower grain yield ha-1 than the highest seed rate of 9 kg ha-1. Dibbling method consistently produced better leaf area plant-1 and consequently out-yielded broadcasting method. Increasing the application of poultry manure rate from 2.5 to 5.0 t ha-1 and NPK fertilizer delayed days to 50% heading, days to physiological maturity and caused more lodged plant. The application of 2.5 and 5 t ha-1 poultry manure and NPK fertilizer positively influenced leaf area plant-1, straw yield ha-1, panicle yield ha-1 and grain yield ha-1, compared to no fertilizer treatment. Also, the application of lower poultry manure rate (2.5 t ha-1) produced optimum performance for leaf area plant-1 and yield characters for higher grain yield ha-1 comparable to the application of 5.0 t ha-1 and NPK fertilizer.The combinations of dibbling at 6 kg seed ha-1 and either poultry manure at 2.5 t ha-1, 5.0 t ha-1 or NPK fertilizer, gave highest grain yield ha-1. Based on the resultsofthis study, itis concluded that, sowing finger millet by dibbling at 6 kg seed ha-1 with application of 2.5 t ha-1 gave maximum grain yield ha-1.
