A field experiment was conducted at the Ladoke Akintola University of Technology, Ogbomoso, in the Guinea savannah zone of South Western Nigeria. Phosphorus fertilizer and plant density required for the optimum growth and yield of Ginger were investigated. The treatments involved five phosphorus fertilizer (alesinloye organic fertilizer) rates applied at 0kg, 15kg, 30kg, 45 kg and 60kg/Pha-1, and three different spacing ( 25 x 50, 35 x 50 and 45 x 50). These were assigned into a factorial experiment and fitted into a randomized complete block design and replicated thrice. The parameters taken were the plant height, number of leaves, number of shoots, length of rhizomes and rhizomes yield. These traits showed significant increase to the application of P rate with optimum value obtained at 60kgPha-1 and at 40 x 50cm planting distance. The combined effect of spacing and fertilizer rate significantly influenced in most of the characters.
