| Family Common Name: | Pea | ||
| Scientific Name: | Lupinus microcarpus | ||
| Common Name: | Valley lupine | ||
| Species Code: | LUMI9 | ||
| Ecotype: | Rogue River-Siskiyou National Forest, Oregon | ||
| General Distribution: | Western North America from southwestern British Columbia south through Oregon and California, including the Mojave Desert, and into Baja California | ||
| Propagation Goal: | Plants | ||
| Propagation Method: | Seed | ||
| ProductType: | Container (plug) | ||
| Stock Type: | 262 ml (16 in3) container | ||
| Time To Grow: | 16 weeks | ||
| Target Specifications: | Stock Type: Container seedling Root System: Firm plug in container. | ||
| Pre-Planting Treatments: | Seeds are placed in a rotating drum lined with sandpaper (Missoula Technology Development Center) for approximately 3 hours to scarify the seed coat. Seeds are then placed in fine mesh bags into a 1% hydrogen peroxide (3:1 water/3% hydrogen peroxide) soak for 24 hours, rinsed, and placed in water for an additional 2 hours. The bags are placed in sealed containers in refrigeration at 1 to 3 °C for 7 days. | ||
| Growing Area Preparation/ Annual Practices for Perennial Crops: |
Seeds are directly sown into containers. Seeds are lightly covered with nursery grit. Growing medium used is 40:20:20:20 peat:composted fir bark:perlite:pumice with Nutricote controlled release fertilizer (18N:6P2O5:8K2O with minors; 180-d release rate at 21C) at the rate of 1.5 gram Nutricote per 262 ml container. |
||
| Establishment Phase: | If scarification is effective, germination is uniform and quite rapid. It is usually complete in 10 to 14 days. Following germination, plants are fertilized with soluble 12-2-14-6Ca-3Mg at 75 ppm for 1 to 2 weeks. | ||
| Length of Establishment Phase: | 2 weeks | ||
| Active Growth Phase: | Plants grow rapidly following establishment, and may need to be top-pruned approximately 3 months following establishment. Soluble fertilizer (20-9-20 NPK, 20-18-18 NPK, or 17-5-24 NPK) at 100 to 150 ppm is applied weekly throughout the growing season. | ||
| Length of Active Growth Phase: | 14 weeks | ||
| Hardening Phase: | No dry-down is done to induce dormancy. Seedlings are moved to an outdoor growing area in late September. | ||
| Length of Hardening Phase: | 2 to 3 weeks | ||
| Harvesting, Storage and Shipping: |
Harvest Date: Mid to late October Storage Conditions: Seedlings are usually outplanted in fall to mid-winter. No storage except in outdoor growing area. Plants are well irrigated prior to shipping and shipped in containers. |
