Example 1 4 p79

• Soil erosion in PNW.
• Normal barley/wheat rotation.
• New crops canola and AWP.
• Test erosion of new crops in no tillage, minimum
  tillage and conventional tillage.

3
Example 1 4 p79

• As much land as needed.
• Cultivators set to 20 feet.
• Tradition drill at 10 feet and no tillage drill
  at 15 feet.
• Design a suitable experiment.

Example 2 5 p.79

• Kentucky blue grass burning is banned as of now.
• Seed Production is related to temperature, length
  of vernalization and day-length.
• Design an experiment to examine production
  systems without burning.

14
Example 2 5 p.79

• 12 cultivars.
• 3 vernalization chambers, each with six shelves.
• 4 glasshouse bays with day-length control.
• 4 benches/bay (15 feet x 3 feet).
• Pot size is 4, 6, or 12.

• 5 cultivars.
• 3 vernalization times, one from each chamber (2
  sods/shelf).
• 12 pots 45/bench
• 3 Replicates/bench (blocked)
• 4 benches (12 reps/treatment).
• 4 day-lengths, one/bay.

Example 3 6 p.80

• Restrictions on insecticides on beans stop BMV.
• Aphids max out at 5 weeks before harvest.
• Apply 6 of water, one inch/4 weeks.
• Reduced irrigation early maturity, less cost.

20
Example 3 6 p.80

• Reduced N accelerated maturity and reduces cost.
• Early maturity is important to avoid aphids and
  hence BMV.

21
Example 3 6 p.80

• Triangular field, 300 x 400 x 500 feet.
• Solid set irrigation every 30 from the 400
  edge.
• Experiment to optimize irrigation and N
  application.

  N/acre.
• Three replicates.

Example 4 2 p.57

• Wild oat infestation reduces yield and quality in
  spring barley.
• Increased N on barley increase crop
  competitiveness against oat.
• Traditionally apply 110 units of N.
• 4 wild oat plants/square foot.

26
Example 4 2 p.57

• Barley predominated by Golden Sunrise and
  Malter.
• 5 wide seed planter (10 to 30 length plots).
• 20 continious planter.
• 5 plot combine
• 200 x 200 of land, 2 locations.
