Synopsis (short abstract) This manual describes techniques that offer two important advantages over relying only upon planting seedlings. First,vegetative propagation allows new trees to be raised at any time, so that seed problems need not affect the choice of suitable planting stock. Second, as has been the case with several common farm crops, vegetative propagation can speed up domestication to allow urgently needed tree planting to be carried out with mixtures of superior selections.

The aim of the present experiment was to assess effectiveness of selected propagation methods, early nursery and field performance of D. mespiliformis (Ebenaceae). For instance, effects of seed pretreatment/root segment cuttings diameter, provenance and soil types on germination and growth vigor of the species was investigated using 144 seeds/root segment; laid in 500 g of three different soil types and soaked/planted in polyethylene bags replicated four times in three treatments and laid in 4×3×3 factorial Completely Randomized Design. Emergence of radicle (days), Seedlings/Shoot Height (cm), number of leaves, and Percentage survival were recorded two weekly for a period of 7 months. Time to event seed germination/shooting data analysis, ANOVA two ways and Generalized Mixed effects Model were used to assess effects of origin, pre treatment/diameter and soil types on germination, shooting and growth of Diospyros mespiliformis. Results indicated that propagation of the species can best be done through seeds and root cuttings. The essay revealed that seeds from woodland, savannah and parkland, sowed in compost and clay and pre treated (boiled water, tegument removed) had the highest germination percentage (69.9-86.67 %), while seeds in the control (no treatment, Inundated Forest and sandy) had very low germination of 17-35 %. No seed treatment showed deficiency in the survival and germination of the seeds of Diospyros mespiliformis, while borehole water aided the survival and bring back early (rapid) germination. Regarding RSC, leafy shoots formed percentage varied from 0 % in river sand to 64.6% in clay and compost substrate after 12 weeks. Results reveal also that among the three classes of diameter, shooting height decreases from clay to sandy while the same variable move in inverse order regarding RSC origin.
