2.8. Experimental Design and Statistical Analysis
The experiment was laid out in Completely Randomized Design (CRD) for all the treatments. The experiment was comprised of different combination and concentrations of plant growth regulators combined with three accessions of Jatropha. Each treatment had five replicates of culture Jars and set as experimental unit. Data collected from each experiment was subjected to statistical analyses using the SAS statistical software (version 9.2) and ANOVA was constructed, followed by mean separation using Fisher’s Least Significance Difference (LSD) at α=5%.
