Answer to Question 1

An advantage of mixed plantings is that it reduces damage by insects that are attracted to plants by smell by confusing them. Mixing also works for underground pests. Roots of
pest-resistant varieties may release compounds that inhibit or kill the insects' larvae.
Sweet potato roots produce an allelopathic compound that reduces the growth of some
weeds.

Answer to Question 2

Students should discuss at least two of the following advantages of using high tunnels:frost
protection, ability to sow seeds in the ground, reduce insect damage, and reduce
the need for pesticides.
