    Abstract: The growth and yield performances of 4 ginger varieties under oil palm plantation environment and different mulch management practices in South Eastern Nigeria were evaluated in a field study conducted in 2007 and 2008 cropping seasons in a privately owned oil palm plantation at Uratta village in Isiala Ngwa North Local Government Area of Abia State, South Eastern Nigeria. Treatment consisted of four ginger varieties [yellow ginger (UG1), black ginger (UG2), Wynad Local (WYL) and Himachel Pradesh (HPL)] in combination with 2 mulch management practices (mulched and unmulched). The treatments were laid out in a split plot arrangement fitted into a randomized complete block design with 3 replications. Results showed that although fresh rhizome yield was consistently lower under the oil palm plantation environment relative to the control, there was a delay and significant reduction in the occurence of yellow leaf spot disease in the plantation compared to the control. UG1 and wynad local varieties out-yielded Himachel Pradesh and UG2 in both plantation environment and in the control irrespective of mulch management practice.
