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.

Example 1 ~ #4 p79Example 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.79Example 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.

Example 2 ~ #5 p.79Example 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”.

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.

Example 3 ~ #6 p.80Example 3 ~ #6 p.80

Reduced N accelerated maturity and reduces cost.

Early maturity is important to avoid aphids and hence BMV.

Example 3 ~ #6 p.80Example 3 ~ #6 p.80

Triangular field, 300 x 400 x 500 feet.

Solid set irrigation every 30’ from the 400’ edge.

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.

Example 4 ~ #2 p.57Example 4 ~ #2 p.57Barley predominated by ‘Golden

Sunrise’ and ‘Malter’.5’ wide seed planter (10’ to 30’
