b. You have been asked to design an experiment to compare the effect of two types of plant food (call them A and B) on tomato plant growth using sixteen plants. These sixteen plants will be grown on a greenhouse bench in two rows of eight as shown below (2 rows of 8 plants). Even though this is in a greenhouse, you are concerned about air temperature (a potential nuisance factor) affecting plant growth. For each item below, describe how you would allocate the treatments to these sixteen tomato plants and the name of the design. 11
b-i You are told that there is no temperature gradient. (i) Name of the design: (ii) Design (allocating A and B to the 16 plants): a b-ii You are told that there is a considerable temperature gradient running against the rows (2). (i) Name of the design: (ii) Design (allocating A and B to the 16 plants):
