Instructor: In this scenario,
let's say you're a grower in Nebraska,
and you're interested in looking
at the broccoli variety Arcadia.
So we filtered by our variety here on the right,
and we see the distribution of studies
is mostly on the coast,
a few studies in the Midwest and none in Nebraska.
How might you use this data
from these locations outside of Nebraska and the Midwest
to extrapolate results and make some predictions
about how this variety might perform on your farm?
To do this, we suggest using the soil texture
and aridity index filters.
When I filter by this variety,
we will note that the aridity index
is automatically filtered
and we see that all of these studies
were performed in humid conditions.
Let's look at soil texture.
On my farm, I know that I have silty loam soil,
so we can click this dropdown menu, uncheck all
and click silty loam.
This brings up results for studies
that were conducted on silty loam soil.
We see that on the coast here in Maine,
our relative yield was negative 18.9%,
here in Virginia, 2.2%,
negative 40% in Pennsylvania,
negative 31 in Indiana,
and 12.1 here in Washington.
So we'll note that these (indistinct) values
are on the lower side for these areas
with similar soil texture and aridity
and if we take a look at the graph,
we'll see that Arcadia
has a moderate relative yield potential.
The upper and lower relative yield values
are closer together, negative 20% for lower, 2% for upper.
We can see that this cultivar
is relatively broadly adapted to different environments,
and that it's likely to perform about the same
as other varieties in these studies.
