Short answer (10 pts each).

1. Consider the following crops: rice, corn, wheat.  Which one is easier to grow?  Why?

 

Open ended response.  Just looking for good, scientifically based or culturally based

reasoning.  For example, one could say corn, because there are more transgenic

variety options that greatly reduce insect and weed control problems.  Or wheat, because

it rarely needs anything but N fertilizer at the proper rate and time.  etc

 

 

 

 

 

 

 

2. What strategies would a wheat grower do to prevent and control disease losses?

 

Variety selection!  (#1)  Choose two or more that differ in resistant diseases common to

the region.  Other ideas:  keep fields drained, plant at the proper time and rate, scout,

timely use of an approved fungicide if needed, etc.

 

 

 

 

 

 

 

 

 

3. Discuss the challenges facing farmers as society demands for ethanol production

    from corn and grain sorghum increase.  For example, what challenges and potential

    problems affect yields the most, and what strategies will the farmer use to reduce the

    risks and put the odds in their favor for high yields and profits?  How can they reduce

    costs without sacrificing yields?  Any comments you have are worth sharing.  Use the

    back of this page if needed to fully express your opinions.

 

Again, open-ended response.  Just looking at your thought processes and use of things

learned in class.  Putting nothing down, or very little, or very much with little substance, can cost you pts here!
