    (FUTO Journal Series, 2016) Adeyemi, A.A.; Ibe, A.E.; Onuoha, G.N.; Ikeazota, E.N.
    Garcinia kola seedling growth under different fertilizer treatments was investigated. The study was carried out at the Federal University of Technology, Owerri. The experiment was laid out in completely randomized design. Three different fertilizers with a control were used for the experiment. Each of the treatments was applied on G. kola seedlings. Sixty seedlings were used for the experiment with fifteen replicates each/treatment. 500 g of fertilizer was applied to each seedling at 10 cm away from the stem and 5 cm depth. Seedlings were allowed to stabilize for two weeks for nutrient assimilation. Information on seedling height, collar diameters, leaf area and production were collected. Data were analyzed using descriptive statistics and one-way ANOVA. The results revealed that there were no significant differences in mean seedling heights, leaf areas and leaf production among the treatments (P > 0.05). However, significant differences existed in mean collar diameters (P < 0.05). Seedlings that received poultry droppings recorded highest mean seedling height (44.71±11.02 cm), while the control yielded the least mean height (39.71±9.71 cm). Nevertheless, the values were not significantly different among the treatments. The mean collar diameter was highest in seedlings that received poultry droppings (2.13±0.36 cm) and least in the control (1.81±0.31 cm). Urea and poultry dropping did not differ significantly in terms of collar diameter growths. Similarly, urea and cow dung were not significantly different in mean effects on collar diameter. However, urea and poultry droppings were significantly different from the control. Poultry dropping was the best manure for G. kola seedling.

    Seed germination and seedling growth of Terminalia ivorensis (A. Chev) in different growth media
    (Federal University of Technology, Owerri, 2015) Ibe, A.E.; Adeyemi, A.A.; Nwuda, B.N.; Asiabaka, C.C.; Onuoha, G.N.
    watering regimes. The experiment was laid out in a completely randomized design. Twelve (12) germination trays each were filled with each of the three sowing media. Each of the trays was sown with thirty (30) T. ivorensis seeds making 360 seeds per sowing medium. A total of 1080 seeds were used for the experiment. Each of the media was divided into three for subjection to watering regimes. Three watering regimes adopted were twice daily, once daily and every-other day. There were four (4) replicates per watering regime under each sowing medium. 0.25 litre water was used for watering on each occasion. Data were collected on germination and seedling growth parameters including heights, collar diameters, leaf areas and leaf production. Data were analyzed using descriptive statistics (frequencies and percentages), Z-test and Oneway analysis of variance. The highest germination percentage was recorded under topsoil with 9.4 % while sterilized river sand had 2.5 % germination, and there was zero germination under sawdust. The result revealed that mean seedling heights and leaf areas were significantly different between topsoil and river sand (P < 0.05). However, there was no significant difference in mean collar diameters under the river sand and top soil (P > 0.05). Mean leaf productions significantly differed between river sand and top soil (P > 0.05). There were no significant differences in mean seedling heights, leaf areas, collar diameters and leaf productions among the three watering regimes (P > 0.05). The study showed T. ivorensis germination was best in topsoil. This study also showed that the best watering regime for the propagation of T. ivorensis is twice daily for the sterilized river sand and once every other-day for topsoil.
