Question

1 a one - year simulation is run with the settings shown below. the resulting yield was 6.6 tons per hectare, or 44% of the maximum yield. what is the most likely cause for the poor yield? resistance type: none, caterpillars, herbicide, caterpillars and herbicide. adjust the amount of herbicide and insecticide and click play to observe corn growth. herbicide (l/ha): 290, insecticide (l/ha): 180. most of the corn was damaged by insects. the corn plants were crowded out by weeds. the corn plants were damaged by the herbicide. all of the above.

Explanation:

Since there is no resistance to caterpillars and a relatively high amount of herbicide (290 L/ha) is used, insects could damage the corn, weeds may not be fully controlled leading to crowding out of corn plants, and the high - level herbicide could damage the corn plants.

Answer:

D. All of the above
