Varieties

Arapaho, UI 114

Soil Preferences

Deep, well drained, fertile sandy loam. Avoid clay loams unless well drained.

Optimum Growing Conditions

Day temperatures 80-90°F and night temperature above 65°F, use windbreaks.

Establishment Methods

Planting Method Direct seeded
Optimum Time 4-6 weeks after last average frost date or seed zone soil temperatures above 60°F
Seeding rate 60-80 lbs/acre (70,000-90,000 plants/acre)
Approx seed/oz 50-100
Seeding depth Sandy loams - 2-2.5"
Loamy sands - 2.5-3"
Clay loams - 1-1.5"
Seedling spacing 2 rows on 40" wide bed
3-5 plants/row ft.

Fertility/Fertilization

Rates presented as actual lbs/acre N2, P2o5, and K2o (base actual rates applied on soil test results).
Generalized rate: 70-80-100 lb/acre* (depending on plant population)
N*60 to 80
P**80
K**100
* Ammonium nitrate is very stable and least likely to evaporate. Urea and ammonium sulfate evaporate if not incorporated.
** Soils testing high to very high in P and K do not usually respond to further applications. Addition of P to soils high in this element can cause iron and zinc deficiency.

Water/Irrigation

15 to 20". Adapted to furrow or sprinkler irrigation. Use of tensiometer 12" depth to monitor available water and schedule irrigations are suggested. Irrigate at 30 centibar.

* The above is a partial listing of controls intended as examples. Some labels may have been revoked since the publication of this guide. Refer to product labels for specifics and use accordingly. Ensure that products with one of the listed active ingredients is registered for the crop it is to be used on. Failure to do the above may result in crop injury, death and/or citation for law violation. Humans, animals and the environment may also be adversely affected by misuse.
** As stated in §205.206 of the National Organic Standards, pest management decisions should follow a hierarchical approach, which should be defined in a farm's organic systems plan. Please ensure that you have followed the appropriate steps and any product to be used in certified organic production systems has been approved by your certifying agent.
