Question 1: An experiment was conducted to study the effects of leaf extract spray with two marine grass plant species on dry weight of two genotypes of tomato, A control treatment (no spray) was also applied to each genotype. The treatments were arranged in a split-plot design with genotype as the main plot and spray treatment as the subplot. The experiment was replicated in four complete blocks. Complete the ANOVA (fill in the shaded areas): (4 points) Source SS MS LL. Block 55.92 6.96 Genotype Error a Spray 102.90 Genotype X Spray 2.66 Error b 9.21 Total 184.24 What are your conclusions regarding the effects of genotype and spray treatments on dry weight on tomato plants? Do you think the use of a Split plot was justified in this case? Give evidence to support your answer. Draw a diagram of a single block for a split-plot and for a factorial RCBD design, showing how the treatments are assigned to the experimental unites. Be sure to label your diagrams. Calculate LSD to compare between means of the genotype x spray interaction in case of split plot and factorial RCBD
