摘要: In this report, methods are developed to estimate yield potentials of biomass crops in various regions within the European Union (EU-12). Different production levels considered; firstly, potential level that can be realized when crop is optimally supplied with water and nutrients free from pests, diseases weeds. Secondly, so-called water-limited recognized. situation, optimal supply weeds, but limited by availability
