VARIETIES:
Blackeye: | Arkansas #1 ( short, determinate bush, 60-70 days) Blackeye #5 (vining, 90-95 days) Blackeye #46 (vining, 90-95 days) |
Cream: | Texas Cream 40 (tall, determinate bush, 80 days) |
Crowder: | Brown Sugar Crowder (vining, 90 days) Mississippi Silver (tall bushy vine, 85-90 days) Zipper Cream (low vine, 90 days) |
Pinkeye: | Texas Pinkeye (tall, determinate bush, 75-85 days) Early Scarlet (determinate bush, 75-85 days) Pinkeye Purple Hull BVR (vining, 90-95 days) |
OPTIMUM GROWING CONDITIONS: Warm to hot days(85 – 95 F) and warm nights (60 – 65 F) with mean temperature 70 – 80 F.
ESTABLISHMENT METHODS: Direct seeded
Optimum time = | Soil temperature > 65 F and frost danger over |
Seeding rate lbs/A = | 12 – 40 |
Seed / oz. = | 200 – 250 |
Seeding depth = | 0.75 – 1.0″. |
Seedling spacing = | 2 – 6″ on 36 – 42″ beds, depending on variety grown. |
FERTILITY/FERTILIZATION: Rates presented as actual lbs/ac N, P205, and K20 (base actual rates on soil test results)
Generalized rate lbs/ac | 35 – 60 – 70 |
N | 20 – 60, preplant applied; none if soil test shows 10-20 ppm and inoculant is used. |
P | 60 – 80, banded approximately 3″ below seed at planting; band only P below seed. |
K | 40 – 100, preplant applied with the nitrogen. None required on High Plains except in Tivoli Sand. |
Lime | 0.5 – 1.0 ton/ac fall applied (East Texas and other areas with pH < 6.0 only). |
WATER/IRRIGATION: 10 – 20″, critical demand period is bloom; maintain uniform moisture throughout fruit set and pod development. Do not water log soils.
PEST MANAGEMENT:
MAJOR DISEASES | CONTROL* |
Viruses | Resistant varieties, sanitation |
Powdery mildew/Rust | Sulfur |
Fusarium wilt | Resistance |
Nematodes | Telone, Telone C17, Vorlex |
MAJOR INSECTS | CONTROL* |
Cowpea curculio | Methoxychlor, weevil-free seed |
Wireworm | Diazinon |
Cutworm | Diazinon, Sevin, Methoxychlor |
Stink bug | Sevin, Lannate |
Aphid | Di-syston, Dimethoate, Diazinon, Malathion |
WEEDS | CONTROL* |
Pre emergence | Dacthal, Pursuit; read label rotation restrictions. |
Preplant incorporated | Treflan, Prowl 3.3 EC, Dual, Pursuit; see rates on label and read rotation restrictions before using. |
Postemergence | Poast, Pursuit; read label rotation restrictions. |
* NOTE — 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 Some labels may have been revoked since the publication of this guide.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. Failure to do so may result in crop injury, death and/or citation for law violation. Humans, animals and the environment may also be adversely affected by misuse. |
HARVEST:
Days after planting | 65 – 80 |
Normal method | Hand: dry seed and some varieties can be mechanically harvested. |
Containers | Field baskets/bulk wagons. |
Grades | Free from defects, blemishes and insect stings. |
Packaging/Handling | 24 lb bushel baskets, 40 lb crates, cardboard boxes containing 12 11-oz cello bags. |
Anticipated yield lbs/A | Dry, 600 – 800; green, 900 – 2000 (15 – 24 bu). |
TRANSIT CONDITIONS: 32 F @ 95 – 98% RH; shelf-life 1 – 2 weeks.
COMMENTS/PRODUCTION KEYS:
- Can be harvested as green snaps, green mature and dry.
- Ship fresh peas under refrigerated conditions.
- Most fields are multiple harvested.
- Three year crop rotation is suggested to reduce potential disease and insect problems.
- Wet cold condition at or following planting induce seed rot and seedling damping off.
- Frost causes pod injury.
- Can be grown as a dry land crop but responds extremely well to irrigation in the form of increased yield and quality.
- Best to use a seed inoculant (nitrogen-fixing bacteria), especially on new pea land, crop does not respond well to high nitrogen fertilization (increased vine growth and reduced pea
yield can result). - Winter rye cover crop prior to planting spring peas aids in reducing nematode problems.
