Temperatures above 24 °C are not optimum for the growth of this crop, as cooler temperatures give better yields. About 1 lb of seed is needed per acre. Use a precision seeder like a Gaspardo or StanHay (vacuum) for raw seed. 3). Basic or complete, fully integrated processing line for freshly cut, packaged, ready-to-eat salads. Used intermittently through the ages, the technique of growing plants in soil-less environments was perfected in the 1940’s. This type of sensor is being deployed in vehicles to alert drivers about the closeness of other vehicles or other things. Whole plants of leaf lettuce are often put in a plastic sleeve and sold 24 to 36 per fiber-board carton. The transformation process typically uses common resources such as labour, capital (for machinery and equipment, … This takes the lettuce to a vacuum chamber, where the air is sucked out, cooling the produce before it’s sent to market. Making a production schedule is not an easy task. The change might be small and one affecting only a single sector while other changes might be major and affecting every industry. Login. Side-place the remainder in either one or two bands 4 inches to the side and 2 inches below the seeded row. Interactive Media Media that has a user interface such as an app, software application or website. Check the 1999 North Carolina Commercial Vegetable Recommendations (AG-586) for current recommendations. Compared to the production of lettuce in hydroponics is found better than produced in the soil. The aim of the present study was to evaluate the use of the technology we have named for the first time as FLOCponics (biofloc + hydroponic) (FP) and conventional aquaponics (AP) systems in producing Nile tilapia (Oreochromis niloticus) juveniles and lettuce (Lactuca sativa). A wire-bound or waxed fiber carton designed to hold 20 to 24 heads is used. Robo lettuce But some people think farming land is old hat. Cannabis trimming technology suppliers are constantly developing more innovative products. The definition of technology with examples. This indoor Japanese farm uses LED lights and hydroponics to produce lettuce 2.5 times faster, with just 1% of the water, when compared to an outdoor farm. He says, “It integrates technology and agriculture and enables year-round production of high quality products.”. Insects and Diseases -- Lettuce is attacked by aphids, armyworms, imported cabbage worm, and loopers. Use of medicines such as antibiotics, hormones and artificial insemination techniques in intensive animal rearing. Use of yeast and bacteria in the large-scale production of bread, beer and wine, youghurt and cheese. Lettuce processing line. Both insects and diseases can be controlled if the correct chemicals are properly applied. Use of plant hormones in plant growing and fruit production. This includes manufacturing products and delivering services. In North Carolina, the crop can be grown as both a spring and fall crop in eastern N.C. and even during midsummer in western N.C. at elevations over 3,000 ft. Repeated exposure to subfreezing temperatures, however, can seriously injure or kill the crop. This will produce stocky plants and reduce the chances of damping-off. Rates of Ethylene Production. Stem Lettuce has a shortened fl eshy stem 10 to 15 cm tall. Examples of mass production for textiles are plain T-shirts, school shirts and socks, with products kept low cost as large amounts are made and bulk materials are cheaper to buy. Figure 1. Leaf lettuce is grown in the coastal areas of Salinas, Technology Guide » 20+ Advanced Technologies » 9 Types of … Innovative technologies for lettuce cultivation Whether in leafs or as a head of lettuce, in the open field or in protected scraps, lettuce production makes use of particularly advanced solutions, such as aeroponic cultivation and the application of artificial intelligence. Days required to grow crop are 40 to 60, leaf lettuce; 70 to 80, head lettuce. In this period, direct seeding would be a good choice provided irrigation is constantly available until the plants are well established. While it seems to many to be a fairly new technology, growing plants hydroponically is actually an ancient system dating back to the hanging gardens of Babylonian and Aztec cultures. Single-cell protein and fungi are use to produce meat substitudes. In heated greenhouses, 4 to 6 weeks is required to grow an acceptable transplant. The seedlings were grown at room temperature at moderate light levels and were fertilized weekly with 20-20-20 plus micronutrients at 100 ppm N. After 4 weeks the lettuce seedlings were about 10 cm tall and had 6 true leaves (Fig. Looks like you’ve clipped this slide to already. Three points should be considered when selecting a field to produce vegetables: field topography, soil type, and water availability and quality. In our non-circulating hydroponics system the lettuce plants were supported on a Styrofoam board floating on the nutrient mix in an easily available plastic bowl. Irrigation -- Irrigate to establish a stand and to keep the crop growing. Optimum growth temperature for lettuce is 16 to 18 °C and the plant can tolerate temperatures as low as 7 °C. Acid is periodically injected to remove bicarbonate and iron precipitates. Soil moisture shortage rainfall will seriously stunt growth and head quality. High bicarbonate, manganese, or iron levels in groundwater in some areas of the Central Coast can plug drip emitters.
