Field studies were carried out aiming to analyse growth and yield responses of cowpea (Vigna unguiculata (L.) Walp) cultivar Epace-10 when subjected to different sources of nitrogen. Plant were grown in a yellow-red Podzolic soil and irrigated by a sprinkler system. Four treatments were defined in function of nitrogen sources. In the Control treatment seeds were not innoculated and grown in residual soil nitrogen (0,02%). In the Innoculated treatment seeds were innoculated with Bradyrhizobium sp and received no additional mineral nitrogen. In the Innoculated + Mineral N treatment seeds were innoculated and one third mineral nitrogen was applied during sowing and two third 20 days after germination (DAG). The amount of nitrogen applied was ...
