Abstract

Nursery experiments were conducted during the rainy season to assess the early growth of Terminalia ivorensis and Khaya senegalensis seedlings in order to ascertain the suitability of the  species for possible plantation establishment in Nigerian drylands. One hundred seeds from each species were germinated, and ten uniformly growing seedlings were selected from each species at two weeks-after-planting. Growth assessment was carried out for 4 months after transplanting These were sown in 25 cm x 25 cm polypots filled with topsoil and replicated 4 times. Germination Percentage (GP) of seeds was determined; and Mean Germination Time (MGT) was ascertained using germination kinetic models. Terminalia ivorensis had a mean height/month of 12.31 cm, while Khaya senegalensis was 13.97 cm. Mean number of leaves/month were 10.88 and 9.20, while  mean basal diameters were 1.98 mm and 11.20 mm, for Terminalia and Khaya seedlings , respectively. Mean biomass raw-weights were 1.29 g and 1.43 g, while mean dry biomass were 0.76 g and 0.84g for the concurrent species. There were no significant differences in the height and number of leaves of the two species, while their basal diameters differed. The nursery performance of both species indicate their ameliorability to growth in drylands. Hence, Terminalia ivorensis and Khaya senegalensis could be raised for large scale afforestation or reforestation in the dryland environments.
