“…However, highly variable biomass yields were observed for all genotypes and fertilization treatments, which ranged from 25.4 Mg ha −1 at the control in ʽBialobrzeskie᾽ to 187.7 Mg ha −1 at the highest fertilization dose in ʽFutura 75᾽ (Table 3). Increasing the rate of N fertilizer led to an increase in inflorescence length and weight (Vera et al, 2004;Campiglia et al, 2017). Nitrogen availability has little effect on hemp seed mass and in our study there were no significant Table 2.…”

“…In contrast, significant yield increases were reported in nitrogen limiting conditions (Van der Werf et al, 1995;Struik et al, 2000;Amaducci et al, 2002;Aubin et al, 2015). Vera et al (2010Vera et al ( , 2004 reported that hemp seed yield increased progressively with increasing nitrogen availability under a high fertilization rate, which ranged from 99 kg N ha −1 to 198 kg N ha −1 depending on growing conditions. According to several studies conducted in the Netherlands, England, Latvia and Italy, nitrogen fertilization rates ranged between 100 and 240 kg N ha -1…”

According to Amaducci et al (2015), the flowering stage in hemp is deemed to be the most important event in hemp cultivation, as it affects production in terms of stems, inflorescences and seeds.…”

Fibre hemp is grown for a multitude of end products derived from its cannabinoids, seed, fibre and wooden core. A key factor that influences the quantity and quality of the production of hemp is nitrogen fertilization. The aim of this study was to determine the response of five well-adapted industrial hemp cultivars to different nitrogen fertilization rates during the 2016 growing season. The experiment was laid out in a split-plot design with two replicates, five main plots (hemp cultivars: 'Bialobrzeskie', 'Tygra', 'Felina 32', 'Sanhtica 27', 'Futura 75') and sub-plots [fertilization treatments: control (N0), fertilizer 46-0-0 at 120 kg ha -1 (N1), 180 kg ha -1 (N2), 240 kg ha -1 (N3)]. For the computation of height, biomass yield, stem dry weight, length and weight of the inflorescences and mean seed weight, 10 plants were randomly selected in each plot. In general, increasing N fertilization rate positively impacts hemp biomass yield, stem dry weight, plant height, and inflorescence indices. Biomass yield, stem dry weight and inflorescence weight increased by 37.3%, 48.2% and 16%, respectively, with the application of 240 kg N ha -1 when compared with the unfertilized control. Plant height and inflorescence length increased from 1.66 to 1.76 m and from 66.2 to 82.9 cm, respectively, with the application of the higher N rate compared with the control, while there were no significant differences between the fertilization treatments for mean seed weight. The varieties 'Tygra' and 'Futura 75' showed the highest values for all the measurement characters. Our results indicate that hemp responded well to the addition of N fertilizer.

S fertilization on industrial hemp in Saskatchewan. Can. J. Plant Sci. 90: 179Á184. Industrial hemp (Cannabis sativa L.) has become a well-known crop in western Canada in recent years, but insufficient information is available on its nutrient requirements for optimum yield. Our objective was to confirm the response of two hemp cultivars to increasing levels of nitrogen (N), phosphorus (P) and sulphur (S) in various sites in the province of Saskatchewan, during 2006Á2008. Increasing N rates significantly increased plant height, biomass, and seed yield, when data were averaged across all sites (location-years), reaching maximum values at about 150 kg N ha(1 of applied N fertilizer. The cultivar Crag was taller and produced greater biomass than the cultivar Finola over all levels of N fertilizer rate. The minimum rate of N fertilizer to achieve maximum height/biomass for Crag, relative to Finola, was 5 kg N ha(1 lower for height (Finola: 163 kg N ha (1 ) but 9 kg N ha (1 higher for biomass (Finola: 180 kg N ha(1 ). Finola seed yield was more responsive to progressively greater rates of N fertilizer. Consequently, maximum seed yield (plateau) was 27% greater for Finola than for Crag, but 198 kg N ha(1 of fertilizer was required to achieve this maximum yield vs. 175 kg N ha(1 for Crag. There was generally little or no response to P fertilizer, on soils with adequate available P, or to S fertilizer on an S-deficient soil. Results from this study indicate that N fertilizer rate and cultivar choice are important management parameters to consider for industrial hemp production.

Cultivar and management effects on industrial hemp yields in Wisconsin

After decades of heavy regulation, growers across the United States were able to begin growing industrial hemp (Cannabis sativa L.) again in 2014. The 2014 and 2018 Farm Bills made it legal for research and production to resume and removed hemp from the list of controlled substances. Because of the long prohibition of hemp production, many questions surrounding best management practices still exist. In 2019 and 2020, studies were conducted in Arlington and Chippewa Falls, Wisconsin to evaluate the effects of cultivar, seeding rate, and nitrogen rate on hemp yield. Two cultivars (X-59 and CRS-1), seeded at three seeding rates (22, 34, and 45 kg ha −1 ) and three nitrogen rates (0, 67, and 134 kg ha −1 ), were evaluated. At Arlington, nitrogen did not impact fiber yield; however, an interaction among cultivar, seeding rate, and nitrogen rate effected grain yield. At Chippewa Falls, fiber yield increased by 20% when nitrogen rate increased from 0 to 67 or 134 kg N. Similarly, grain yield increased by 52% when the nitrogen rate increased from 0 to 67 or 134 kg ha N. The effect of seeding rate alone was highly variable with no consistent pattern on response variables measured. Therefore, the overall effect of nitrogen rate was more consistent than the effect of seeding rate on response variables measured. Ultimately, management recommendations will be dependent on local conditions; however, hemp does respond to the addition of nitrogen fertilizer.
