  abstract = {{C}owpea occupies a considerable place in the nutritional and economic balance of the rural population of {B}urkina {F}aso. {H}owever, its cultivation is marked by yield instability linked to soil depletion of nutrients, especially {N} and {P},

and irregular rains. {T}he objective of this study was to evaluate the effect of phosphorus fertilization with the rock phosphate named {B}urkina{P}, on the spatial and temporal variability of cowpea nodulation and yield. {A} multilocation

test was conducted in 12 and 16 farmers'fields in 2013 and 2014, respectively, in 3 villages of 3 provinces of the northern region of {B}urkina {F}aso. {T}wo treatments were compared: za{\¨ie} without ({ZS}) and za{\¨ie} with {B}urkina{P} ({ZP}). {O}verall,

dry weights of nodules and shoots at flowering stage, and grain at harvest, were significantly increased by {B}urkina{P}. {I}t is concluded that in soils where low availability of {P} limits crop yields of cowpea especially in arid sud-saharan

areas of {W}est {A}frica, the input of {B}urkina{P} can improve cowpea {N}2-fixation, and increase and stabilize cowpea yields.},
