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 |

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.Pest Management

* 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 Some labels may have been revoked since the publication of this guide.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.
Harvest
| Days after planting | 75 to 95 |
|---|---|
| Normal method | Direct combine or knife undercut and combine |
| Containers | Usually sold in 50 lb bags |
| Grades | Processors require < 5% cracks and check-coat. Dry pack tolerates higher percent defects but downgrades quality and price. |
| Packaging/Handling | Sold in consumer carton packs and loose measure by weight in supermarkets |
| Anticipated yield/acre | 1,000-2,500 |
Storage/Transit Conditions
Dry, 12 to 13% moistureComments/Production Keys
- Less tolerant of heat, wind, and drought than southern peas (cowpeas)
- Use of windbreaks is suggested
- Use of bush type varieties recommended to help reduce losses from soilborne diseases.
- Use of tensiometer 12" depth to monitor available water and schedule irrigations is suggested
Irrigate at 30 centibar stress threshold (tensiometers work best in light, sandy loam soils, and may give false readings in heavier soils). - Undercutting as harvest maturity approaches is suggested in southern part of state due to occurence of untimely rainfall, which can initiate regrowth
- Uniform moisture distribution required to reduce incidence of hard seedcoat factor
