Abstract

The  effects of burning, intercropping and dry grass  mulching on the performance  of two

cocoyam (tannia) cultivars were investigated. The study indicated that burning reduced the

fresh weights of leaves of cocoyams irrespective of the cultivar while increasing the number

of cormels per corm but reduced corms/cormel weight. However, the frequency of root and

corm rot (cocoyam decline disease) was least in burnt than in unburnt plots irrespective of

the cultivar. In all  the cultivars (“Eduhie” and Edeocha)  studied, cocoyam sole-crops had

the least frequency of occurrences of the disease than the intercropped plants. The disease

was not recorded  in sole crops mulched with 10 tonnes/ha for all  the cultivars.

Recommendations based      on  this research and  the findings  of other workers on  burning,

intercropping and grass mulching are made.
