In 1999, roughly of land in Mexico was dedicated to jalapeño production; , that had decreased to . Jalapeños account for thirty percent of Mexico's chili production, and while the total land area used for cultivation has decreased, there has been a 1.5% increase in volume yield per year in Mexico due to increasing irrigation, use of greenhouses, better equipment, knowledge, and improved techniques. Because of this, in 2009, 619,000 tons of jalapeños were produced with 42% of the crop coming from
Chihuahua, 12.9% from
Sinaloa, 6.6% from
Jalisco, and 6.3% from
Michoacán.
La Costeña controls about 60% of the world market and, according to company published figures, exports 16% of the peppers that Mexico produces, an 80% share of the 20% that Mexico exports in total. The US imports 98% of La Costeña's exports. According to the
USDA, since 2010
California produces the most jalapeños, followed by
New Mexico and
Texas - a total of of peppers in 2014. It is difficult to get accurate statistics on chilies and specific chilies as growers are not fond of keeping and sharing such data and reporting agencies often lump all green chilies together, or all hot chilies, with no separation of pod type. In New Mexico in 2002 the crop of jalapeños were worth $3 million at the farm gate and $20 million after processing.
China,
Peru,
Spain, and
India also produce commercial
chilies, including jalapeños. garden. Red jalapeños are used to make
sriracha sauce. Jalapeños are a pod type of
Capsicum annuum. The growing period is 70–80 days. When mature, the plant stands tall. Typically, a plant produces 25 to 35 pods. During a growing period, a plant will be picked multiple times. As the growing season ends, the peppers turn red, as seen in
sriracha sauce. Jalapeños thrive in a number of soil types and temperatures, though they prefer warmer climates, provided they have adequate water. The optimum temperature for seed
germination is , with degradation of germination seen above and little to no germination occurring at ; at the time to 50% germination rate depends on cultivar and seed lot but was tested as being between 4 and 5 days, which is shorter than
cayenne. A
pH of 4.5 to 7.0 is preferred for growing jalapeños, and well-drained soil is essential for healthy plants. Jalapeños need at least 6 to 8 hours of sunlight per day. Experiments show that unlike
bell peppers at least 7.5 millimolar (mM) nitrogen is needed for optimal pod production, and 15 to 22 mM nitrogen produces the best result: the plant produces both more leaves and more pods, rather than just more leaves. Once picked, individual peppers may turn to red of their own accord. The peppers can be eaten green or red. Though usually grown as an annual they are perennial and if protected from frost can produce during multiple years, as with all
Capsicum annuum. Jalapeños are subject to
root rot and foliar blight, both often caused by
Phytophthora capsici; over-watering worsens the condition as the fungus grows best in warm wet environments. Crop rotation can help, and resistant strains of jalapeño, such as the 'NuMex Vaquero' and '
TAM Mild Jalapeño', have been and are being bred as this is of major commercial impact throughout the world. As jalapeños are a cultivar, the diseases are common to
Capsicum annuum:
Verticillium wilt,
Cercospora capsici,
Powdery mildew,
Colletotrichum capsici (Ripe Rot),
Erwinia carotovora (Soft Rot),
Beet curly top virus,
Tospovirus (Tomato spotted wilt virus),
Pepper mottle virus,
Tobacco mosaic virus, Pepper
Geminiviridae, and
Root-knot nematode being among the major commercially important diseases. After harvest, if jalapeños are stored at they have a shelf life of up to 3–5 weeks. Jalapeños produce 0.1–0.2 μL per kg per hour of
ethylene, very low for chilies, and do not respond to ethylene treatment. Holding jalapeños at 20–25 °C and high humidity can be used to complete the ripening of picked jalapeños. A hot water dip of for 4 minutes is used to kill off molds that may exist on the picked peppers without damaging them. The majority of jalapeños are wet processed, canned, or pickled on harvesting for use in mixes, prepared food products, and
salsas.
Hybrids and sub-cultivars There are a wide variety of breeds for consumer and commercial use of jalapeño plants. The majority fall under one of four categories:
F1 hybrids, where the parent plants have been hand-emasculated and cross-bred to produce uniform offspring with
hybrid vigor; cultivars which are F-11 or F-12 hybrids or later generations where a stable unique population has been developed;
landraces; and F2 hybrids. Cultivars are researched and created to promote desirable traits. Common traits selected for are resistance to viruses and other pepper-related diseases, milder peppers, early ripening, more attractive fruit in terms of size, wall thickness, and corking, and higher yields. Notable cultivars include 'Early Jalapeño', 'TAM Mild Jalapeño', 'TAM Mild Jalapeño II', 'NuMex Vaquero', 'TAM Dulcito', 'Waialua',
Biker Billy and 'NuMex Primavera'.
Sweet hybrids Sweet hybridized varieties have been created with no "heat", although they retain the look and flavor of a jalapeño. ==Eating characteristics==
