Effect of Nitrogen Levels on Crop Yield

Hard Data Representation Interpreting Experimental Data

During an experiment, a team of scientists investigated how the varying levels of nitrogen in the soil affected the yield of two different crops, corn and soybeans. They planted equal plots of each crop with different nitrogen levels (0 kg/ha, 50 kg/ha, 100 kg/ha, and 150 kg/ha) and measured the crop yield in kilograms per hectare after the growing season was complete. The data collected was summarized in the table below:

Nitrogen Level (kg/ha) | Corn Yield (kg/ha) | Soybean Yield (kg/ha)

0 | 2,000 | 1,500

50 | 2,500 | 1,750

100 | 3,000 | 2,200

150 | 3,200 | 2,500

Based on the data, what can be concluded about the effect of nitrogen levels on the yield of corn and soybeans?

Higher nitrogen levels consistently increased the yield of both crops.

Corn yield is more responsive to nitrogen levels than soybean yield.

Soybean yield decreases with increasing nitrogen levels.

There is no effect of nitrogen levels on crop yield.
