    Effect of water stress on the yield performance of seven dura x pisifera oil palm progenies
    (Journal of Ghana Science Association, 2008-06) Dwarko, D.A.; Nuertey, B.N.; Baidoo-Addo, K.; Asamoah, T.E.O; Marfo-Ahenkora, E.; Okyere-Boateng, G.; Opoku, A.
    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.

    Improving the growth of oil palm seedlings with biostimulants neb-26 and neb29
    (Journal of Ghana Science Association, 2012-06) Danso, F.; Opoku, A.; Baidoo-Addo, K.; Danso, I; Afari, P.A.; Nuertey, B.N.
    Bio timulant appear an emerging option to improving seedling growth and development and a a production cost reduction strategy. They are known to stimulate the biological activitie of the oil microbe , increase root growth, enhance root nutrient uptake and reduce the need for addi­ tional fertilizer application. The study was to evaluate the effect of two bio timulant (NEB-26 and NEB-29) and their combinations with other fertilizer formulations on the growth of oil palm eedling at the nursery. The experiment, conducted at Okyinso near Kade from May 2005 to March 2006, wa a randomized complete block design with twelve treatment in three replica­ tion . Plant growth parameters such as plant height, butt circumference, frond dry weight leaf area and leaf area index were measured monthly. The results on the vegetative mea urement indicate that a mixture of NEB-26 with NPKMg fertilizer formulation and NEB-29 with PKMg fertilizer formulation promoted growth of the seedlings better than ole application of NEB-26 and EB-29 alone. .
