VARIETIES
Jalapeno- TAM Mild-1, TAM Veracruz, Coyama, Hy Mitla, Tula, Tulleon, Grande, Delicias, Coyama, Sakata 616, Simmer Heat 6000
Serrono- Fiesta, Tampico, Tuxlas, Hidalgo
Ancho- San Martin, Red Knight
Cayenne- Mesilla
Anaheim- Sonara

SOIL PREFERENCE
Fine sandy loam, well drained, pH 6.0 - 7.5; can tolerate heavier soils especially for fall crop.

OPTIMUM GROWING CONDITIONS
Warm season crop, hot days (85 - 95oF) with cool nights (65 - 70oF). Bloom drop will occur with temperatures above 95oF. Excessively high temperatures will reduce fruit size.

ESTABLISHMENT METHODS
Direct seeded, can be transplanted.
Optimum time=
Direct seed-
Spring- when soil temperature >60oF.
Fall- approx 120 days prior to average first frost date.
Transplant-
Spring- after last average frost date.
Fall- approximately 85 - 100 days prior to average frost date.
Seeding rate= 2 - 4 lbs/A;
Approx seed/oz= 4,500
Seeding depth= 0.5" -0.75"
Seedling spacing= 1 - 2 rows on 30 - 40" raised beds with in-row spacing of 2 - 6", maximum of 8 ". If needed, thin seedlings to stand 35 - 40 days after emergence. Approximately 30,000 plants / A required for optimum yields.

FERTILITY/FERTILIZATION
Rates presented as actual lbs/Acre N2, P2 O5 and K2O (base application rates on soil test results).
Generalized rate lbs/A: 150 - 60 - 60
N= 120 - 170; 60 lbs pre-plant broadcast incorporated + 30-50 lbs side-dressed at thinning (4 -6" height) or after transplanting + 20 - 30 lbs after 2nd harvest. Calcium nitrate induces quicker plant response than most other N forms.
P= 50 - 80; band 2" below seed at planting.
K= 40 - 80; pre-plant with N.
*NOTE - Use a high phosphate starter solution with transplants.(5 lb/50 gallons water applied at 8 oz. /plant.

WATER/IRRIGATION REQUIREMENTS
High water demand, 25 - 30"; uniform moisture distribution throughout growing season.

*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 some labels may have been revoked since the publication of this guide.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 misuses.

HARVEST
Hand harvested, determinant types can be machine harvested
Days after planting= 110 - 120 days (75 - 85 days for transplants). Yields maximized by delaying harvest until 5-10 % of fruit are red.
Optimum stage= Fully mature green, firm, solid pods 2-2.5" in length.
Field containers= Burlap bags.
Grading/Handling=
Fresh market- allow stems to remain on fruit.
Processing- stem removal required.
Packaging= Normally sold in bulk burlap bags.
Anticipated yield tons/A= 8 - 10.

STORAGE/TRANSIT CONDITIONS
45 - 55oF with 80 % RH; maximum storage duration 2-3 weeks. Normally shipped unrefrigerated in bulk.

COMMENTS/PRODUCTION KEYS
  • Initiating harvest too early will result in reduction of yields. Maximize yields by delaying first harvest until 5- 10 % of the fruit show red color. Harvest on a 2-3 week interval thereafter.
  • In the Lower Rio Grande Valley or in areas where high humidity prevails, moisture stressing seedling 25 - 30 days after establishment enhances root development, earliness and subsequent yields. This practice may not be successful in drier areas.
  • Deep cultivate bottom of water furrows, shallow cultivate closer to plants. Do not root prune. Most roots run north and south.
  • Can not tolerate any moisture stress during bloom.
    • Scoville units is the measure of relative heat level of hot peppers or capsaicin concentration (heat causing compound found in capsicum species) of pepper fruits.
    • Average heat level in Scoville units for jalapeno is 3,500 to 4,500. Scoville units for other hot peppers are:
      Habanero/Scotch Bonnet = 200,000 - 300,000; Chiltecpin (round) = 70,000;
      Tabasco = 30,000 - 50,000; Chilipiquin (long)= 40,000; Cayenne = 35,000;
      Serrano = 7,000 - 25,000
