Question 1

The yield response to in NPK fertilizers applied to a rice farm is represented as Y = 0.45X + 75.4 - 0.0040 where Y is the grain yield (bu/a) and X is the rate lbs/a. What would be the rate for maximum yield?
◦ 46.2
◦ 75.2
◦ 56.2
◦ 55.3

Question 2

Which of the following correctly describes the dilution effect?
◦ Yield increases from an application of one nutrient can reduce the concentration of the second nutrient, but the greater plant growth results in greater uptake of the second nutrient.
◦ Yield increases from an application of one nutrient do not have an effect on the concentration of the second nutrient, but the greater plant growth results in equal uptake of the second nutrient later.
◦ Yield increases from an application of one nutrient can increase the concentration of the second nutrient, and the greater plant growth results in greater uptake of the second nutrient.
◦ Yield increases from an application of one nutrient can increase the concentration of the second nutrient, but the greater plant growth does not affect the second nutrient later.
