Question

An experiment was planned to study the effect of Sulphate, Potash and Super Phosphate on the yield of potatoes. All the combinations of 2 levels of Super Phosphate [0 cent (p0) and 5 cent (p1)/ acre] and two levels of Sulphate and Potash [0 cent (k0) and 5 cent (k1)/acre] were studied in a randomised block design with 4 replications each. The (1/70) yields [lb per plot = (1/70) acre] obtained are given in table below:

To analyze the data and draw conclusions, we can perform an analysis of variance (ANOVA) to determine whether the factors (Super Phosphate, Sulphate, and Potash) have a significant effect on the yield of potatoes. Additionally, we can compute the mean yields for each treatment combination to identify any notable patterns.

First, let's organize the data into a table format for better understanding:

Block Treatment Combination Yield (lbs per plot)
I     p0k0                   23                    
I     k0                     25                    
I     p0                     22                    
I     p1k1                   38                    
II     p0                     40                    
II     k0                     26
