Ligno-Cellulose Quality and Calorific Value of <i>Elymus elongatus</i> L. and the Novel <i>Secale cereanum</i> Tested Under Central European Conditions

Abstract The objective of the paper is to determine ligno-cellulose quality and calorific value tall wheatgrass Szarvasi-1 Alkar, as well perennial rye Kriszta Gergő cultivars, tested within a huge pilot field experiment. experiment was established in autumn 2016 carried out until 2020, while four trial sites with marginal soil three nutrition treatments (intensive, semi-intensive untreated control) were included well. impact nutrition, years, sites, cultivars on statistically evaluated main effects, two complete data set points acid-detergent fibre (ADF), lignin (ADL), crude cellulose (CE), hemicellulose (HEM), neutral-detergent (NDF) high heating (HHV), primarily terms content secondarily yield. In content, decreased alternating order: each them over least important yield has been confirmed most factor followed by then finally impact. Average ADF according sequence – Alkar 45.95 45.65 42.25 42.97%, ADL 8.67 8.24 8.51 8.37%, CE 37.27 37.41 33.74 34.60%, HEM 24.14 24.78 25.46 25.00%, NDF 70.03 70.43 67.71 67.71% HHV 16.86 16.89 17.21 17.17 MJ/kg, respectively. maximum values order 6.373 6.180 6.112 4.983 t/ha, 1.340 1.374 1.261 1.027 5.253 5.111 4.851 3.997 3.000 3.097 3.052 2.655 9.285 9.133 9.164 7.626 t/ha 225.3 221.1 228.9 185.7 GJ/ha,
