Air-dried stem yields in Ontario have from 1998 and onward ranged from 2.6–14.0 tonnes of dry, retted stalks per hectare (1–5.5 t/ac) at 12% moisture. Yields in Kent County, have averaged 8.75 t/ha (3.5 t/ac). Northern Ontario crops averaged 6.1 t/ha (2.5 t/ac) in 1998. Statistic for the European Union for 2008 to 2010 say that the average yield of hemp straw has varied between 6.3 and 7.3 ton per ha. Only a part of that is bast fiber. Around one tonne of bast fiber and 2–3 tonnes of core material can be decorticated from 3–4 tonnes of good-quality, dry-retted straw. For an annual yield of this level is it in Ontario recommended to add nitrogen (N):70–110 kg/ha, phosphate (P2O5): up to 80 kg/ha and potash (K2O): 40–90 kg/ha. The average yield of dry hemp stalks in Europe was 6 ton/ha (2.4 ton/ac) in 2001 and 2002.
Hemp seeds are one of the best sources of plant-based protein and GLA and have a wide variety of health benefits, including their ability to improve heart health, stimulate digestion, build muscle mass, eliminate insomnia, treat anemia, and aid in weight loss. They also help to stimulate metabolic activity, boost the immune system, reduce symptoms of menopause and menstruation, improve skin and hair health, and build stronger bones.
While the Marihuana Tax Act of 1937 had just been signed into law, the United States Department of Agriculture lifted the tax on hemp cultivation during WW II. Before WW II, the U.S. Navy used Jute and Manila Hemp from the Philippines and Indonesia for the cordage on their ships. During the war, Japan cut off those supply lines. America was forced to turn inward and revitalize the cultivation of Hemp on U.S. soils.
Shelled hemp seeds are becoming a popular dietary supplement because of their high protein content and healthful fatty acids. Hemp seeds come from the same plants, Cannabis sativa or C. indica, that produce marijuana, although the plants are cultivated and processed differently so that hemp seeds contain very low levels of psychoactive cannabinols such as delta-9-tetrahydrocannabinol, or THC. Shelled hemp seeds are generally safe, but some people may experience some undesired side effects.
In Western Europe, the cultivation of hemp was not legally banned by the 1930s, but the commercial cultivation stopped by then, due to decreased demand compared to increasingly popular artificial fibers. Speculation about the potential for commercial cultivation of hemp in large quantities has been criticized due to successful competition from other fibers for many products. The world production of hemp fiber fell from over 300,000 metric tons 1961 to about 75,000 metric tons in the early 1990s and has after that been stable at that level.
Hemp seed has a modest content of calcium, which is a necessary element in the creation and strengthening of bones, and also helps to repair the damaged bone matter. Furthermore, the positive boost of calcium which you get from hemp seed and its oil will help you reduce your chances of developing conditions like osteoporosis, arthritis, and help in improving joint health.
Hemp seeds are high in nutritional value and contain 20 different varieties of amino acids and all nine of the essential amino acids (like flax). Some essential amino acids can't be naturally produced by the body and these seeds have the capacity to supplement them in the body. They contain high amounts of protein, which helps in strengthening the immune system, thereby, reducing the instances of diseases, besides helping in excreting toxins from the body. Studies in the recent past have shown that consuming hemp seeds whether raw or in oil form, has the capacity to aid in the healing process of diseases related to immune deficiency. There is no other food substance which contains such high quantities of essential fatty acids found in hemp seeds, higher than even flaxseed and other nut or seed oil as well as containing high amounts of vitamin E and trace minerals. It has a balanced ratio of omega 3 to 6 fats at around a three to one ratio. This won't help correct your omega balance if it's off, but it gives you the right balance to start with.
