Effect of water stress on the yield performance of seven dura x pisifera oil palm progenies

English

Seven Dura x Pisifera (DxP) oil palm progenies were evaluated for yield in three climatic locations with different mean annual water deficit (150 mm, 250 mm a'nd 400 mm) values in order to deter­ mine their tolerance to water stress. The design used was a randomized complete block in 4 replica­ tions with a plot size of 0.48 ha (42 palms). Data was collected on number of bunches and bunch weight (kg) and fresh fruit bunch (FFB) yield (Tonnes/ha) was subsequently calculated. The data was analyzed-using Analysis of Variance (ANOVA) and means separated by Duncan's Multiple Range Test (DMRT). Significant progeny effects at each location on the yield parameters were ob­ served and, based on these results, three stress tolerant progenies were identified. The identification and selection of drought tolerant progenies for planting in marginal areas and the use of drought sensitive ones in optimum and favourable area in Ghana will lead to efficient utilization of available soil moisture and improvement in overall yields.
