Agronomy Question with Answer

21. The phrase dusting it in when used in wheat production refers to:

  1. planting the seed very deep into a layer of soil moisture to get below a dry surface layer
  2. planting the seed at recommended depth into a loose, well-tilled soil with good moisture
  3. planting the seed shallow into a dry soil surface hoping for a rain so it can germinate later
  4. planting the seed at recommended depth with a no-till drill which cuts through the residue left from a previous crop to get good seed-to-soil contact

22. The practice of no-till planting grain sorghum into the stubble of a wheat crop immediately after wheat harvest in late June is called:

  1. fallowing
  2. intercropping
  3. double cropping
  4. strip cropping

  2. corn and wheat in the US; corn and wheat in Kansas
  3. wheat and soybeans in the US; corn and wheat in Kansas

24. The wheat diseases soil borne mosaic, streak mosaic, and barley yellow dwarf are all caused by:

25. To slow the development of insect resistance (Insect Resistance Management) in crops genetically engineered with Bt technology, farmers have been required to plant a portion (usually 20%) of the field to non-Bt hybrids as a refuge. Some new corn hybrids like Pioneer Optimum® AcreMax™ now include RIB technology which means:

  1. There is no longer any refuge requirement since there are multiple resistance genes in these new hybrids (stacked traits)
  2. The refuge requirement is reduced to 5% of the field that must be planted in a separate area
  3. The non-BT seed is mixed in the bag, thus no separate refuge area needs to be planted
  4. The refuge requirement has been increased to 30% of the field since rootworm resistance was reported in the Corn Belt last year

26. Which of the following conditions would not likely be a result of using a no-till system that leaves crop residue on the soil surface versus incorporating the residue with tillage?

  1. more water infiltration
  2. less overwintering of insect and disease pests
  3. cooler soil temperature
  4. less wind and water erosion

27. Which of the following is the most common liquid fertilizer carrier that supplies both nitrogen and phosphorus with an analysis of 10-34-0?

  1. urea
  2. urea-ammonium nitrate (UAN)
  3. di-ammonium phosphate (DAP)
  4. ammonium polyphosphate (APP)

28. Which of the following is the predominant cool season, introduced, perennial forage grass crop grown in Kansas for pasture and hay?

  3. bermudagrass

  2. corn
  3. wheat
  4. sunflower
