Production aspects will include past to present, west to east and from north to south. Production aspects will also include baby leaf, teen leaf and mature. Production in the areas throughout the E. U. will be covered and areas in the UK, The Netherlands, France, Belgium, Germany, Spain, Portugal, Italy, Switzerland and Turkey will be highlighted. Planting methodologies and equipment will also be discussed. An overview of the disease and pest problems and threats facing spinach crops in Europe will be covered. In addition, focus will be given to the main growers, processors, and supermarkets. An overview of the spinach and the value added products that are consumed in the E.U. will also be presented. 19 Current spinach production and distribution in Japan Margaret Savage1 and Ryo Kimura2 1 Alf Christianson Seed, Mt. Vernon, WA; 2 Sakata Seed Corporation, Yokohama, Japan This presentation will show the main production area of Japan, some of the current production methods, harvesting and packaging. Tokyo is located in Kanto area with 42 million people, which is 1/3 the total population of Japan. 49% of Japan’s spinach production is in the Kanto area which is 42% of the total area of Japan. The main growing season is fall with the spinach grown outside. The summer growing area moves to the north or to high elevations. The summer spinach is grown in plastic houses providing protection. The Japanese spinach grower who has more than 1 ha of plastic houses is considered a big farmer. Most farmers are still harvesting spinach by hand. Machine harvesting is being introduced into a few areas to help shorten harvest time. Baby leaf spinach is still a minor crop and processing for the frozen market is slightly increasing. 20 Evolution of the fresh market spinach industry in California Jay Schafer Schafer Ag Services, LLC Based on the FAO statistics, a reported 812,980 hectares (> 2.0 M acres) of spinach were grown worldwide in 2009. By far the biggest producer was China with 78% or 634,150 hectares (1.567 million acres) with the US and Japan each growing about 2.5% each of 20,000-plus hectares, Today California leads the US in all categories of spinach production. Using the USDA/NASS statistics for 2010, CA produced 68.8% of the total pounds for 538.8 million pounds. This included 70.6% of the Fresh Market and 61.8% of the reported processed (canned and frozen).
