“…claim that while industrial hemp was positively affected by nitrogen fertilisation up to 200 kg N/ha, the response to phosphorus and potassium fertilisation remained neglectable. However, the best option to evaluate lignocellulose quality is to provide the valuation in terms of quality content and quality yield as well, while an important impact on nutrition can be expected (Kron et al 2017;Tóth & Dupľák 2023). Pagnani et al (2018) also recorded the positive effect of plant growth-promoting rhizobacteria (PGPR) on the aboveground biomass of hemp, as well as the accumulation of plant secondary metabolites and consequently antioxidant capacity.…”

Hemp (Cannabis sativa L.) is one of the traditional crops currently being newly re-introduced in Slovakia and cultivated for multi-purpose uses, while still there is a lack of crop biomass yield data. The main objective of the paper is to document the yield of aboveground biomass of selected cultivars of hemp ('Bialobrzeskie', 'Felina', 'Santhica', 'Epsilon', and 'Futura'), which were tested in the pilot open-field experiments conducted during 2009 − 2012, immediately after a wave of legislative changes. The trial was agronomically designed including three nitrogen treatments as follows: (i) T1 30 kg N/ha (the full 30 kg/ha in the phenophase BBCH 31), (ii) T2 60 kg N/ha (dividing on 30 + 30 kg/ha in the phenophase BBCH 31 and 51, respectively), and (iii) T3 90 kg N/ha (dividing on 30 + 30 + 30 kg/ha in the phenophase BBCH 31, 51 and 59, respectively); whereas NPK 15-15-15 in the dose of 200 kg/ha was applied before the sowing all across the treatments. The total average dry matter (DM) yield of 9.49 t/ha was achieved, ranging from 2.12 to 16.80 t/ha. DM yield was affected mainly by years (F-ratio 337.40, P-value 0.0000), followed by nitrogen treatment (F-ratio 47.86, P-value 0.0001), then by cultivars (F-ratio 22.37, P-value 0.0019) and finally by replications (F-ratio 0.65, P-value 0.58). However, the need for further studies aimed to quantify more precisely the response of the cultivars to the weather and soil conditions is necessary, especially the cultivars of new and foreign origin.

“…The humus content in the soil, soil pH, and content of available P, K, Mg, B, Mn, Cu, Zn, and Fe were also increased. Other studies conducted by Tóth et al [58] showed a positive effect of Humac Agro, when used at a dose of 1 t ha −1 , on the yield and biometric parameters of switchgrass (Panicum virgatum L.). BCW has the ability to absorb and exchange ions between the soil solution and the solid phase.…”

Modern agricultural technologies have contributed to a significant reduction in the amount of soil organic matter. Brown coal waste (BCW), with low energy content, can be used to neutralize this process, contributing to the recuperation of soil fertility and to environmental protection. More studies need to be conducted on organomineral fertilizers based on BCW and applied to soils with low humus content. Apart from increasing soil production capacity in arable fields, BCW could be used for the reclamation of industrially contaminated areas and degraded soils, in the vicinity of motorways and in soilless agriculture. It can also be used as a sorbent of gases emitted from slurry during its storage such as NH3, H2S, mercaptans, volatile fulvic acids (FAs); as a component of sewage sludge compost; as a natural additive to calf feed; and for the production of adsorbents for sewage and wastewater treatment.

“…For this purpose another 315 sets of biometric data were applied as independent variables. These complementary parameters (crop yield, plant height, and dry matter content at harvest) were the subject of the former paper ( [13]). Finally, the cultivar order based on the average DM yield achieved, as used in the tables, is listed in the results of the former paper.…”

“…The crop phytomass was collected and quality analyses were also performed in 2018-2022, despite the low switchgrass yield in the establishment year (2018). A more detailed description of the screening trial in terms of trial site, nutrition treatments, agronomy, weather and soil conditions, plant material, biometric parameters, and collection of plant samples is presented in a former paper [13].…”

The main objective of the paper was to determine the ligno-cellulose quality and calorific value of switchgrass Panicum virgatum L. The impact of nutrition treatments (pre-sowing soil humic amendment HA and/or NPK, with annual dose of N on both the treatments, and untreated control UC) and years were evaluated as main effects within a pilot experiment with seven cultivars tested during 2018–2022. Two data sets of acid detergent fiber (ADF), acid detergent lignin (ADL), crude cellulose (CE), hemicellulose (HEM), neutral detergent fiber (NDF), and high heating value (HHV) were evaluated, the primary one in terms of quality content and the secondary one in terms of quality yield. The average ADF content of the switchgrass was 43.94% (range 30.15–50.91), while the average contents of ADL, CE, HEM, NDF, and HHV were 9.21% (6.02–12.41), 34.73% (17.98–40.08), 30.49% (21.34–38.41), 74.43% (59.20–81.15%), and 17.206 kJ g−1 (16.579–17.799), respectively. An adequate value of ADF yield was 4.17 Mg ha−1 (0.01–29.31), while for ADL, CE, HEM, NDF and HHV this was 0.79 Mg ha−1 (0.00–5.39), 3.37 Mg ha−1 (0.01–23.92), 2.79 Mg ha−1 (0.01–17.66), 6.96 Mg ha−1 (0.01–46.93), and 1.466 hGJ ha−1 (0.003–10.603), respectively. In terms of the both quality sets the cultivar was confirmed to be the most important factor followed by the year, with nutrition having the least impact. This impact order of the main effects was valid for each of the parameters. Moreover, in terms of quality yield the formation of homogeneity groups corresponded with dry matter yield and therefore with the order of cultivars (EG 1101 ˃ BO Master ˃ EG 1102 ˃ Kanlow ˃ Alamo ˃ Carthage ˃ NJ Ecotype), the years (2021 ˃ 2020 ˃ 2022 ˃ 2019 ˃ 2018), and the treatments (HA ˃ NPK ˃ UC).
