ABSTRACT

 The weaning potential of some Iocaliy sourced substrates (River sand, Coconut fiber, Raffia palm fiber, Sawdust, Rice husk and Wood ash ) and their combinations on in vitro raised cocoyam (Colocasia esculenta ) were conducted to detennine and ascertain the responses of cocoyam (Colocasia escu!enta. var coco India) .The result showed that the greatest survival rates were obtained from Rice husk followed by saw dust when used alone and in combined forms. River sand when used alone showed poor performance based on the survival rate but supported cocoyam growth and survival when river sand is mixed with the other substrates {coconut fiber, raffia palm fiber, saw dust and Rice husk). Wood ash failed to support the growth /survival of the cocoyam when used alone and in combined forms hence indicating that wood ash is not good to be used as weaning substrate.ABSTRACT
