    Effect of planting method and spacing on the growth parameters of three Bambara groundnut cultivars in two Agro-climatic zones of Sierra Leone
    (2023-01-15) Bendu, John Mod
    Field trials were conducted in two agro-climatic zones of the country (Lungi and Kabala) to evaluate the effect of planting methods and inter-row spacing on the growth parameters of three Bambara groundnut cultivars. The experiment consisted of a factorial 18 treatment combinations of two planting methods (mound and flat), three inter-row spacing (50 cm x 10 cm, 50 cm x 15 cm, and 50 cm x 20 cm), and three Bambara groundnut cultivars (Lubam1, Lubam 2, and Kabam 1). The study shows that planting Bambara groundnut using mounds produced higher values of the assessed growth parameters compared to planting Bambara groundnut on flat land. The result further shows that the wider inter-row spacing (50 cm x 20 cm) on average recorded the highest value for all the assessed growth parameters. Furthermore, Kabam1 was observed to have recorded the highest value for all the growth parameters in both locations. Thus, for optimum growth parameters to be achieved, it is recommended that Kabam1 should be planted on mound using the inter-row spacing of 50 cm x 20cm.

    Effect of Planting Method and Spacing on the Yield and Yield Components of Three Bambara Groundnut Cultivars in two Agro-Climatic Zones of Sierra Leone
    (2023-02-28) Bendu, John Mod
    Identification of optimum inter-row spacing, planting method, and suitable cultivar is essential for maximizing the yield of any crop. The study was conducted in two agro-climatic zones to determine the appropriate inter-row spacing, planting method, and suitable Bambara groundnut cultivars that can improve crop yield and yield components. The treatments consisted of two planting methods, three inter-row spacing, and three Bambara groundnut cultivars. The study shows those yield parameters, including grain yield, biomass yield, total biomass yield, 100 seed weight, and fresh pod weight, were higher in Lungi when planting was done on a mound, whilst the value of these variables was higher in Kabala when planting was done on flat. For inter-row spacing, higher values were recorded using the wider inter-row spacing (50 cm x 20 cm) for most of the assessed yield and yield-related components. The result further shows that lubam1 recorded higher values for the yield and yield-related components at both locations. In addition, values for all the yield and yield-related components were, on average higher in Kabala compared to Lungi. In conclusion, to achieve higher yield and yield-related components of Bambara groundnut, it lubam1should be planted on a mound at Lungi and on flat land at Kabala using the wider inter-row spacing of 50 cm x 20 cm.
