Transpiration and biomass production of the bioenergy crop Giant Knotweed Igniscum under various supplies of water and nutrients
Soil water availability, nutrient supply and climatic conditions are key factors for plant production. For a sustainable integration of bioenergy plants into agricultural systems, detailed studies on their water uses and growth performances are needed. The new bioenergy plant Igniscum Candy is a cul...

Soil water availability, nutrient supply and climatic conditions are key factors for plant production.
