The influence of flower removal on tuber yield and biomass characteristics of Helianthus tuberosus L. in a semi-arid area

Abstract Jerusalem artichoke (Helianthus tuberosus L.) is an important source of biomass for biofuels production. To evaluate its potential as a feedstock for biofuel, calorific value, ash, and carbon (C) and nitrogen (N) contents were investigated under different flower removal treatments during 2015–2016 in the Inner Mongolia autonomous region of China. Total biomass of flower removal treatments was significantly (P
