An experiment was conducted in a lath house at the Horticulture farm, Luyengo Campus of the University of Swaziland to assess the effects of organic fertilizers on yield and quality of lettuce grown in river sand. Production levels and areas 3.1 South Africa Productions levels are increasing in South Africa. Make beds 0.75 – 1.0 m wide. It is a progressing industry in the Philippines given the increasing need for healthy and safe food and in effort to contribute in protecting the environment. The results indicated that combined use of green manure and farmyard manure can be successfully used in organic lettuce production. Total and marketable yields (g/ plant), head length and diameter (cm), pH, soluble solids content (%) and total acidity were investigated. It provides a practical, methodological guide for setting up family gardens for the production of nutritious, safe food crops, thatcrops that would contribute fibres, minerals and vitamins to the diets of populations affected by food insecurity. 4. Zero Hunger Challenge- Antigua and Barbuda . Vegetable production in a nutshell 2 In drier areas, lime and potassium are less likely to be needed in large quantities, if at all, but phosphorus will probably be deficient in virgin soils. Lettuce (Lactuca sativa L.) is the most popular salad vegetable. The highest nitrate levels were observed in the medium and maximum inorganic fertilization treatments (572–664 mg kg−1) in all crop seasons. Bacterial rot can be minimized by sanitation. A trend of superiority of the different level of chicken manure application was observed as lettuce provided with 60 t/ha exhibited higher values in number of leaves, plant height, marketable yield and mean leaf dry mass. It is best to intercrop onion, chives or garlic in the beds with marigold. Yield was determined by weighing the fresh harvested lettuce and dry weight at 50 days after transplanting (DAT) and lettuce harvested were subjected to proximate composition analysis. production of lettuce plants grown in hydroponic and aeroponic systems at different flow rates at the end of growing per iod (50 days). The study involved three types of organic manure (poultry, pig and cattle manures) and two types of phosphorus fertilizer (Ogun Rock, Lettuce is a high value salad vegetable rich in minerals, vitamins and antioxidants.With the increasing awareness on ill effect of chemicals on human health and environment, the demand for residue free organic lettuce is increased sharply. If working with … Associate Professor of Horticulture UF/IFAS Horticultural Sciences Dept. ], grown annually as a green manure crop following a nematode-susceptible crop [potato (Solanum tuberosum L.) or cucumber (Cucumis sativus L.)], reduced the RKN population as effectively as the control treatment (soybean cultivar with no known RKN resistance and one nematicide application). University of California Agriculture and Natural Resoures. Highest ROI was obtained in T2. The treatments were: T1 - Recommended organic Although vegetables can be grown on a wide range of soil types, most vegetables are not well adapted to heavy clay soil types. The vermicompost treatment showed a higher contribution of Mg, Fe, Zn, and Cu, and lower Na in lettuce leaf content when compared to compost usage. Chapter 18. Performs well in cool weather conditions. Application of vermicompost (5 t ha-1) inoculated with Azophos emerged as second best combination for most of the yield and yield attributing traits for organic lettuce production. Chicken manure is natural, locally available and relatively cheap material that the organic vegetable growers can obtain. It should be of practical value, to small processors, trainers, extension workers and non-governmental organizations (NGOs) who provide training and support to individuals engaged in the production of fresh-cut tropical produce for sale. These results indicated that organic management positively affected soil organic matter content, thus improving soil quality and productivity. Transplant during cloudy days or late afternoon. A short summary of this paper. economic performance of lettuce in recommended organic production practices with local 5. 7- and 0-day pretransplant interval on bare ground and plastic mulch, respectively. Lettuce is the most popular of the salad crops and is of great commercial importance; first-time Lettuce cultivated in ancient Egypt. 3. treatments and replicated four times. It is also used as decoration for other food preparations. The varieties commonly grown are Boston, Black Seeded Simpson, Iceberg, Grand Rapids and Great Lakes. The research aimed to characterize organic vegetables production environment in Central Luzon, Philippines.Survey, key informants Seven long-term fertilization treatments were tested for their effect on plant growth and nitrate concentration in the external lettuce leaves. practices. contents: Asparagus Bean Cabbage Carrots Cauliflower Celery Cucumber Eggplants Lettuce Okra Onion Leek Chinese Cabbage [Pechay] Pepper Radish Yard long beans [sitao] Sweet Peas Tomato Watermelon Designed for small operations to provide local production of head lettuce as well as the opportunities, there is mix...
