The effect of animal manures on susceptibility of cowpea Var. moussa local to infection by root-knot nematode; Meloidogyne javanica Treub.
The effect of three different types of animal manures namely; poultry, goat and cow dung on the susceptibility of cowpea (Vigna unguiculata (L.) Walp) Var moussa local to root-knot nematode infection caused by Meloidogyne javanica was tested in a replicated pot experiment. Manured plants were inoculated with 2000 eggs of M. javanica while uninoculated manured plants served as control for each manure type and unmanured but inoculated plants as general control. The result showed that unmanured and inoculated plants were susceptible to M. javanica to varying degrees. Plants applied with poultry manure were more resistant to root-knot nematode infection followed by those applied with cow dung and goat dropping in that order. The most susceptible plants were those inoculated but not applied with manure. Gall index and resistance rating showed that plants fertilized with poultry manure, cow dung and goat droppings were resistant, moderately resistant and susceptible, respectively.
