claimPhosphorus fertilization affects industrial hemp plant height, tensile strength, and elasticity of bast fibers, but does not affect grain, stem, or biomass yield.
claimThe optimal period to harvest industrial hemp for bast fiber is before the grains are completely mature, which is typically 70 to 90 days after sowing.
claimMonoecious cultivars of industrial hemp are used in dual-purpose production, allowing growers to produce both grain (seed used for food) and fiber.
claimAs the hemp plant develops, parts of the plant mature and flower, resulting in higher yields of grain and cannabinoids.
claimWaiting longer than full maturity or 70% grain ripeness to harvest industrial hemp causes yield losses due to reduced moisture and nutrient concentrations.
claimThe yield of hemp bast fibers, hurds, and grains is influenced by agronomic conditions including seed selection, soil condition, pest control, nutrient management, time of harvest, and sowing density, according to Grabowska and Koziara (2006).
claimIndustrial hemp grown for grain requires a warmer climate and longer growing seasons compared to hemp grown for fiber.
claimWhen growing industrial hemp for high grain or cannabinoid yields, the crop should be harvested at full maturity or when 70% of the grains are ripe.
claimOperators of combines and augers should run the equipment at lower speeds than normal to avoid unnecessary losses to the quality and yield of grain.
claimStalks from grain varieties are often left to rot in the field after harvest because the return on the low-quality lignified fiber is often not worth the labor required to process it.
claimLater planting of industrial hemp may reduce stem length and mass, negatively impacting grain and fiber production.
claimTo obtain high-quality bast fiber from industrial hemp, the plant should be harvested before grain and cannabinoids begin to develop.
procedureGrain and dual-purpose industrial hemp varieties are harvested using axial flow combine harvesters, which cut the hemp and separate the grain from the stalks.
measurementIndustrial hemp grown for grain and cannabinoid yield typically utilizes the lowest sowing densities, ranging between 10 and 20 kg/ha, according to Burczyk et al. (2009).
claimHemp grown for grain and cannabinoids is typically shorter than hemp grown for fiber.
measurementIndustrial hemp yields of stem, grain, and inflorescence combined are optimized by a density of 120 plants per square meter with 0.5 meter interrow spacing, according to Krüger et al. (2022) and Zheljazkov et al. (2023).
claimSecondary macronutrients and micronutrients such as magnesium and calcium have slight effects on industrial hemp plant growth but no direct effect on grain and bast fiber yield, with the exception of boron and copper.
measurementThe hemp variety Felina 32 produced 2337 kg ha-1 of grain under full irrigation, which was 3.8 times higher than the yield achieved under limited irrigation.
measurementDual-purpose hemp varieties yield 850 kg/ha of grain, compared to 958.3 kg/ha for grain-only varieties.

claimThe introduction of hemp grown for grain and fiber in Michigan increases the risk of cross-pollination for marijuana and CBD hemp growers.
claimIndustrial hemp is cultivated to produce fiber, grain, or non-intoxicating medicinal compounds such as cannabidiol (CBD).
claimIndustrial hemp grown for grain requires male plants and pollen to produce food, feed, and oil.

claimCurrently, approximately 17% of plant species provide 90% of the world's food supply, which is primarily contributed by grains produced using fertilizers that may result in decreased nutrient density and increased energy.
claimGrains are high in omega-6 fatty acids and carbohydrates, but low in omega-3 fatty acids and antioxidants compared to leafy green vegetables.
