Step 1
A description to include the following:
Answer
-
The results indicate that below 100% nitrate concentration leads to less growth in pea plants, while above 100% also results in lesser growth.
-
The optimum nitrate concentration for the growth of pea plants is 100%, which corresponds to a maximum height of 176 mm.
