Scottish Summers Day
2
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.

17
Example 2 5 p.79
  • 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.

Example 3 6 p.80
  • 6 cultivars
  • 4 irrigations, 4, 5, 6, 7.
  • 6 N levels 120, 140, 160, 180, 200, 210 units
    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.
