Oil palm production in Papua New Guinea

Foster H.L., . and Barr J., . (1992) Oil palm production in Papua New Guinea. [Proceedings Paper]

Six oil palm developments have been established in Papua New Guinea. However yield information is only available from three areas since the remaining projects are only just coming into production. In the areas having soils derived mainly from alluvially redeposited volcanic material Kimbe and Popondetta initial FFB yields after opening from bush are high but soon all off to below 20 t/ha/yr if fertilizer is not applied. However it appears that with current material FFB yields in the region of 30 t/ha/yr can be maintained in both areas mainly by the regular application of N fertilizer. The natural availability of chlorine in these soils is poor and the application of a chloride containing fertilizer is also often necessary particularly in drier areas. Regular N fertilizer application tends to depress Mg levels which results in an additional need for Mg in the Kimbe area. Whilst neither P nor K fertilizer appears necessary in these two areas at present K deficiencies may develop with time. Phosphate fertilizer is the major requirement on the ash soils at Bialla. Although initial yields in this particular area are high and fall only slowly fertilizers do not seem able to prevent a gradual decline in nutrient levels particular Mg and yields even in the presence of fertilizers drop to 20 t/ha/yr. The source of most planting material in Papua New Guinea is seed from Dami Research Station near Kimbe in West Britain where initial breeding material was imported from Malaysia in 1967. Early progeny trials indicated that most progress could be made by phenotypic selection for secondary characters mainly leaf area ratio and leaf Mg level plus additional selection for high oil extraction ratio. Parental material is currently being tested in a large area of progeny trials planted in West New Britain. The early results indicate the high yields which can be achieved when both parents have high general combining abilities. Such parents will be used for clonal seed production in the future

Abstract

Six oil palm developments have been established in Papua New Guinea. However yield information is only available from three areas since the remaining projects are only just coming into production. In the areas having soils derived mainly from alluvially redeposited volcanic material Kimbe and Popondetta initial FFB yields after opening from bush are high but soon all off to below 20 t/ha/yr if fertilizer is not applied. However it appears that with current material FFB yields in the region of 30 t/ha/yr can be maintained in both areas mainly by the regular application of N fertilizer. The natural availability of chlorine in these soils is poor and the application of a chloride containing fertilizer is also often necessary particularly in drier areas. Regular N fertilizer application tends to depress Mg levels which results in an additional need for Mg in the Kimbe area. Whilst neither P nor K fertilizer appears necessary in these two areas at present K deficiencies may develop with time. Phosphate fertilizer is the major requirement on the ash soils at Bialla. Although initial yields in this particular area are high and fall only slowly fertilizers do not seem able to prevent a gradual decline in nutrient levels particular Mg and yields even in the presence of fertilizers drop to 20 t/ha/yr. The source of most planting material in Papua New Guinea is seed from Dami Research Station near Kimbe in West Britain where initial breeding material was imported from Malaysia in 1967. Early progeny trials indicated that most progress could be made by phenotypic selection for secondary characters mainly leaf area ratio and leaf Mg level plus additional selection for high oil extraction ratio. Parental material is currently being tested in a large area of progeny trials planted in West New Britain. The early results indicate the high yields which can be achieved when both parents have high general combining abilities. Such parents will be used for clonal seed production in the future
