||This study proposes to evaluate the influence of the spacing row and NPK 15-15-15 fertilizer and goat manure on Panicum maximum seed production and fodder nutritive value harvested in south Benin on ferralitic soil from 2015 to 2017. The experiment was a factorial design comprising all combinations of 4 row spacings (20, 40, 60 and 80 cm) and 6 fertilizers: six levels of fertilizer: (F0) No goat manure (Control) (F1), 100 kg NPK 15-15-15, (F2) 20 t/ha goat manure, (F3) 15 t/ha goat manure, (F4) 10t/ha goat manure + 33kg NPK 15-15-15 and (F5) 5 tons + 66 Kg NPK/ha. Four replications were used in the experiment. The results showed that wider row spacing (60 cm) enhanced seed production in this experiment. Number of total tillers/tussock, fertile tillers/tussocks and spike length were significantly greater under the widest rows spacing (60 cm and 80 cm). The best seed yield got with row spacing 60 cm (392.1 kg.ha-1) and 45.5% of caryopses germinate after six months of storage against 14.5% for spikelet. Seed yield and its attributes increased significantly with NPK combined to goat manures (F4).
