According to a study published in the Notre Dame University journal, The American Midland Naturalist, wild hemp here in the USA produces 8,500 pounds of seed per acre. This study of feral hemp is titled, An Ecological Study of Naturalized Hemp (Cannabis sativa L.) in East-Central Illinois, by Alan Haney and Benjamin B. Kutscheid from the University of Indiana at Urbana, Department of Biology.
Cold pressing of hemp seeds yields over 300 gallons of oil and 6,000 pounds of high protein hemp meal. That is 6 barrels of oil produced per acre, which is extremely healthy while fresh, and 3 tons of high protein food per acre. This oil production rate is three times more productive than the next most productive seed oil crops: soybeans, sunflower seeds and canola/rapeseed, which produce 100 to 115 gallons of oil per acre. Hemp seed oil will be the most productive source of biodiesel fuel when legalized, and it is also a nontoxic resource for plastics and many other synthesized products.
Per acre, hemp is the most productive fiber on earth, making 10 tons of bast fiber, for canvas, rope, lace and linen, and 25 tons of hurd fiber, for paper and building materials. Hemp stalks produce two types of fiber, the bast fiber, or the outer bark, and the hurd fiber, or the inner woody core of the stalk.
The US Department of Agriculture’s own Bulletin No. 404 said that the waste product from making canvas, rope and linen from cannabis hemp bast fiber, this waste product, the hurd fiber, is more than 4 times more productive than trees for fiber production for paper and building materials. The USDA produced a movie during WWII called “Hemp for Victory” that promoted hemp farming for the war effort, and it is available online for free on YouTube.
