Butterhead types are also sleeved or can be packed like head lettuce with 24 heads to a smaller sized carton. In the Piedmont, lettuce is intermediate in season and probably is best as a late spring and early fall crop. The seeds should be planted in rows 4 to 6 inches apart. On the other hand, the evolution of modern technology has disadvantages, for example, dependence on new technology. The definition of personal technology with examples.

High bicarbonate, manganese, or iron levels in groundwater in some areas of the Central Coast can plug drip emitters. How to Improve Production Scheduling. Lettuce Production Patterns and Practices Timelines of growing and harvesting activities in each growing region Comparison of ground preparation activities Pattern of growing activities for a single ranch Comparison of growing conditions and irrigation practices between growing regions. Spring head lettuce often fails because it is planted too late, and for this reason you should consider transplants. Link: Unit 1 Notes. Three points should be considered when selecting a field to produce vegetables: field topography, soil type, and water availability and quality. Example of floating raft system Credits: UF/IFAS Figure 3. This includes manufacturing products and delivering services. Romaine lettuce is sensitive to ethylene. You will have to harvest every 2 to 3 days, depending on moisture and temperature. This type of sensor is being deployed in vehicles to alert drivers about the closeness of other vehicles or other things. INTRODUCTION SCIENTIFIC NAME: Lactuta sativa L.

Consult your Cooperative Extension agent regarding pest build-up, proper diagnosis, and control. About 6 oz of seed and 300 ft2 of bed space is needed to grow transplants for 1 acre. Using technology adopted from automobile and semiconductor plants, he hopes to run an operation that would normally need 100 people with only 20 permanent staff. Benefits. Whole plants of leaf lettuce are often put in a plastic sleeve and sold 24 to 36 per fiber-board carton. Technology. Thus, automation and robotics systems need to be integrated for such operations. Those early machines used a band saw to cut across the width of a high-density, 80-inch-wide bed and lifted the product to a platform. Because of proximity sensors, the number of accidents on roads have reduced and driving has become safe for drivers. 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. Now customize the name of a clipboard to store your clips. Robo lettuce But some people think farming land is old hat. In this period, direct seeding would be a good choice provided irrigation is constantly available until the plants are well established. Vacuum cooling is the primary method for cooling in the major lettuce growing areas. Leaf and butterhead types can be kept for 1 to 2 weeks in cold storage. 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. In some areas, devices can replace the human mind. Unit 2. Also, aquaponics contributes to save water and for the maximum utilization of nutrients and culture areas. 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. 3). Romaine has requirements similar to head lettuce, except it can stand more heat. Lettuce with microchips. Smith agrees. From 12:15-12:45 p.m. there also will be a meeting of the Indiana Hydroponic Growers Association. Planting The Crop -- Lettuce can be either transplanted or seeded. Fig. Blue River Technology’s LettuceBot, a precision thinning machine, visually assesses each plant in a Salinas, California, lettuce field and decides which ones to keep to optimize yield. Because of proximity sensors, the number of accidents on roads have reduced and driving has become safe for drivers. The decision of whether to apply the second sidedressing will have to be based on the appearance of the crop and the rate at which it is growing. In addition, vegetables can be grown conventionally or using organic farming methods. Social Media Digital communities that allow individuals to communicate, share and produce media. The most practical method for N.C. is to stack the cartons in a cold room with high humidity and force cold air through the stack with high-velocity fans.

Whole plants of leaf lettuce are often put in a plastic sleeve and sold 24 to 36 per fiber-board carton. Lettuce can tolerate a few days of temperatures from 80 to 850F, provided that nights are cool. For example, in a survey of 14 low to medium technology growers in the Sydney Basin vegetable production area, 11 did not know the volume of runoff from their crop (Mubiru, 2007). The first sidedressing should be made soon after plants begin to grow. If soil potassium and phosphorous level is high, 500 to 600 lb of 10-20-20 equivalent per acre should be adequate. This takes the lettuce to a vacuum chamber, where the air is sucked out, cooling the produce before it’s sent to market. Head lettuce can be held for 2 to 3 weeks at 320F and 95% relative humidity. Packing should be done in the field. Optimum growth temperature for lettuce is 16 to 18 °C and the plant can tolerate temperatures as low as 7 °C.

Link: Complete Notes. of lettuce, and probably in most vegetative tissue, sub-lethal levels of stress induce only transitory increases in C 2 H 4 production, which have minimal lasting effects. Cooling and Shipping -- Unless the crop is to be sold locally, the lettuce must be cooled before shipment. Video of LED powered lettuce production in Holland (Deliscious) Dec 04. For example, accessing crops for maintenance, monitoring, and pulling for harvesting typically requires added labor time through use of ladders or scissors lift in vertical farming (Fig. The fall crop should be seeded about 80 days before the expected first hard freeze (Aug. 15 to Sept. 1 in the East and July 25 to Aug. 15 in the West). Rank. However, to be accepted by the growing industry, these products have to provide a solution to the current and future problems producers face, and they must be designed specifically for the cannabis market. Lettuce was considered a sacred plant of the reproduction god Min, and it was carried during his festivals and placed near his images. The lettuce is then wrapped, boxed and run along another conveyer to a waiting truck. 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. Production Management. The transformation process typically uses common resources such as labour, capital (for machinery and equipment, … Lettuce is the most popular of the salad crops and is of great commercial importance; first-time Lettuce cultivated in ancient Egypt.

Internal head temperature should be lowered to 34 to 380F for best shipping and holding conditions. Lettuce should be packaged "flat pack" (non-bulge) to avoid crushing the heads. A wire-bound or waxed fiber carton designed to hold 20 to 24 heads is used. Leaf and butterhead types should be grown in double rows 12 inches apart and 8 to 10 inches in row spacing. Diseases are damping-off, mildews, and sclerotinia. Most leaf types are ready in 50 to 60 days after seeding and 30 to 45 days after transplanting. Ilyana A. In-row spacing -- 12 inches in double rows or 9 inches in 4 rows per bed. Interactive Media Media that has a user interface such as an app, software application or website.
