Abstract

The study investigated the effect of cassava peel on the growth and development of Gmelina arborea seedlings. The treatment was made up of cassava peel applied to top soil at 1 g, 2 g, 3 g, 4 g, 5 g, 6 g, 7 g, 8 g, 9 g, 10 g. The treatments were replicated three times. The treatments were mixed with 20 kg of soil thereby making a total of thirty three (33). The experiment, which lasted eight weeks, was laid out in Complete Randomized Design (CRD) and the following variables were assessed; stem height, stem diameter, leaf length and leaf production. The data collected were subjected to analysis of variance (ANOVA) and mean separation was carried out using Least Significant Difference (LSD). The result obtained showed that treatment 6 g gave the best response in term of number of leaves with mean 16.35 while treatment 2 g had the least performance with mean 6.67. The treatment 3 g of cassava peel performed best in terms of leaf length with mean 18.00 while 10 g and 8 g treatments had the lowest stem diameter of 29 cm. With respect to plant height, the treatment of 6 g of cassava peel application had the best response with plant height of 46.67 cm, while the least value of 20.67 cm was recorded in treatment 8 g. Hence, the control (0 g) has significant difference from treatment 8 g. In all the variables assessed, the control showed close values with treatment 8 g, 9 g and 10 g. The result shows a higher level of significant difference to the control at p < 0.05. However, it is recommended that when raising Gmelina arborea where the traits, plant height and leaves are of importance, 6 g of cassava peel is better adapted. Hence, the plant could be raised in the absence of any treatment where appropriate soil is used.
