Abstract: Using goat manure may substantially increase cowpea bean productivity. This study evaluated the yield of ‘pingo de ouro’ cowpea bean under different sowing densities and goat doses in the region of Mossoró, Brazil. The experiment was conducted from October to December 2016 at the Experimental Farm Rafael Fernandes, Mossoró-RN, Brazil. Treatments arranged in two-way factorial with four goat manure doses (0.0, 0.5, 1 and 2 kg m-1), and two sowing densities of bean (75,000 and 37,500 plants ha-1), with three replicates. The experiment was performed in complete randomized blocks design. We evaluated the number and length of pods per plant, number of seed per pod, weight of 100 dry grains and dry grain yield. Higher grain yield occurred using 2.0 kg m-1 of goat manure (1,162.4 kg ha-1 or 234 kg 2,000 m-2) and 75,000 plants ha-1 (693.4 kg ha-1 or 138.6 kg 2,000 m-2). High sowing density in combination with goat manure is an affective.
