Ligno-cellulose quality and calorific value of green phytomass of Silphium perfoliatum L. cultivated on marginal soils under conditions of moderate continental climate of Central Europe

Abstract

The aim of study was to determine ligno-cellulose quality and calorific value of cup plant Silphium perfoliatum L., whereas impact of nutrition, years and sites on the quality were evaluated as main effects within a huge pilot field experiment. Two complete 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, a primary one in terms of quality content and a secondary one in terms of quality yield. Average, minimal and maximal ADF content was
