VARIETIES
| Napa types- |
China Express, China Pride, China Flash, China Delight, Napa 50,
Napa 60 Tango |
| Michihili- |
Jade Pagoda, Monument |
|
SOIL PREFERENCE
Fertile, well-drained, medium textured soils, pH range of 6.0 - 6.5; relatively
well adapted to heavy soils, but poorly adapted to light sands, can experience
BO deficiency in sands.
|
OPTIMUM GROWING CONDITIONS
Cool days (55-70oF) with cool to cold nights (40-50oF).
Temperatures above 75oF may cause tip burn. Prolonged temperature
of 55oF can cause bolting; 15 - 20oF is normal freeze
threshold. |
ESTABLISHMENT
Direct seeded or transplanted
|
| Optimum time= |
| Spring- |
soil seed zone temperature >50oF |
| Fall- |
soil seed zone temperature <100oF |
| Seeding rate lbs/A= |
0.5 - 1.5 lbs/A at 0.25" depth (raw seed);
6 - 8 lbs/A (coated seed) at 0.5" depth. |
| Approx seed/oz= |
9,000 |
| Seedling spacing= |
| Fresh market- |
1 - 2 rows on 24 to 40" wide raised beds with 10-18" in-row spacing |
| Processing- |
|
|
FERTILITY/FERTILIZATION
Rates presented as actual lbs/A N2, P2O and K2O (base actual application
rates on soil test results).
|
| Generalized rate lbs/A: |
150 - 75 - 80 |
| N- |
100 - 130 pre-plant broadcast incorporated or split banded 4"
on either of seed row, or injected through irrigation water; 25
- 30 lbs N/A side-dressed at thinning (4 true-leaf stage), or at
transplanting. |
| P- |
60 - 80 banded approx 2" below seed at planting. |
| K- |
80 - 100 (Potassium not normally required in most areas of Texas) |
|
| *Note*- Use high phosphate
starter solution on transplants (5 lbs 5-20-10, etc./100 gal water-8 oz/plt). |
WATER/IRRIGATION
High water demand (20 - 30"). Uniform moisture levels required throughout
growing season for optimum yields. |

COMMENTS/PRODUCTION KEYS
- Warm temperatures and increasing day length will cause early flowering
of the heads.
- Soils pH >7.8 may induce black hollow stems; Solubor(Bo) at 5-10
lbs/A foliar applied prior to heading reduces severity.
- Crop may have an alleopathic adverse effect on following crop.
- High nitrogen requirements.
- Shallow, horizontal rooting patterns dictates very shallow cultivation
to ovoid root pruning and reduced yields.
- Production on light soils requires high level of management.
- Better suited to early fall production in most areas of the state.
- Water management very critical for stand establishment of early
fall direct seeded crop.
