Description
Early growth or Gmelina arborea under 3 different mulch treatments and an unmulched control was investigated. Plants were grown in drained polythene bags measuring 36 cm flat width and 40 cm deep. The mulch treatments were plastic and 6 t/ha and 12 t/ha fresh Panicum maximum. The experiment was rain-Ced and was a completely randomised design with 5 replications. Three weeks after germination 2 seedlings were transplanted into each polythene bag. Plant height and leaf area measurements at weekly intervals started at the 7th week after transplanting (WAT). Shoot biomass and root biomass were determined at the 18th WAT. Vertical growth was highest in plastic mulched plants and least in unmulched plants. The Panicum maximum mulched plants were intermediate. Shoot biomass, root biomass and leaf area were also highest in plastic mulched plants while unmulched plants had the second highest values. Analysis of variance showed no significant differences between the treatments for any of the variables measured.
