A researcher wanted to determine the effect of zinc (10g/ha, 15g/ha, 20g/ha) on the quality of coconut seedlings. Four seedlings were planted in fifteen equality sized plots. Each zinc level was applied to five randomly selected plots. After a month, the dry weight (in g) of leaves in each plot was obtained.   1. The application of treatment to experimental units are replicated ___ times. 2. The use of equally-sized plots corresponds to what principle of experimental design?  A. Randomization  B. Replication C. Local control  D. Comparison
