Plant Science Systems-Switch-Grass

Switch-grass is a phenomenal crop for South Dakota growing conditions and can be used as an emergency crop around grassed waterways to control erosion, feedlots to provide cover/grassing in down times, as an emergency protein-rouphage source for livestock and a source for ethanol fuel production.

A producer is using a 32’ drill traveling at 5.2 mph.

Hopper capacity is 95 bushels (24#/bu.)

Seeding rate is 20# per acre.

It is combining time and the producer is using a rotary combine (small and seed grains special) He measures a 20 square foot area to determine his loss and finds 27 seeds on the ground. 127,000 seeds are in a bushel.

Storage= a bushel of Switch-grass per 1.2 cubic feet.

Yield= 17bu./acre

1. How many acres can one do on fill?

a. 40 acres b. 114 acres c. 1234 acres d. 13

2. How many minutes of running time are between fills?

a. 37 minutes b. 339 minutes c. 64 minutes d. 79 minutes

3. If the producer needs to seed 403 acres, how many bushels should one order from the seed supplier?

a. 301 bu. b. 45 bu. c. 296 bu. d. 336 bu.

4. At $.21 per pound for seed, What should the check be written for?

a. 1693.44 b. 1245. 75 c. 1856.00 d. 934.12

5. The monitor on the drill has a red light indicating light application rate of seed. One should: a. increase the speed of the seed cups b. increase the width of the metering mechanism c. speed up the tractor d. increase the machine overlap by altering the GPS.

6. What is the field loss per acre?

.a. .463 bu. b. 9.34 bu. c. 5.67 bu d. .189 bu.

7. If decreasing the speed of travel and decreasing the wind speed of the fan at the final chaffers and sieves fails to alleviate the problem, one should:

a. increase rotor speed b. increase the shoe distance c. raise the sieve height d. decrease the speed of the header.

8. If the grain is failing to separate from 3% of the heads one should: a. increase rotor speed b. increase the shoe distance c. raise the sieve height d. decrease the speed of the header

9. How large a bin should the producer set aside for his crop?

a. 82212 bu. b. 75200 c. 69000 bu. d. 34060 bu.

10. If one of his bins is 32’ in diameter. How high will the crop set in the bin level full?

a. 34.78 feet tall b. 67.23 feet tall c. 58.78 feet tall d. 102.27 feet tall
