Leaf area index (LAI) and radiation use efficiency (RUE) are two key crop parameters widely used to estimate the biomass production and carbon accumulation. However, long term LAI and RUE has rarely been studied on arable land in fast growing poplar short rotation coppice (SRC) and cereal crops. For better understanding and improving the potential of biomass accumulation of poplar SRC on arable land, and cereal crops (winter wheat and spring barely), we evaluated and compared the development of LAI and RUE in SRC poplar culture, winter wheat and spring barley. Poplar SRC culture was based on hybrid poplar clone J-105 (Populus nigra x P. maximowiczii) grown in a high-density (9216 trees ha-1). Poplar plantation was established in 2002, winter wheat (Triticum aestivum) was sowed in October 2011 and spring barley (Hordeum vulgare) was sowed in April to May 2012. Our results demonstrate an enhanced LAImax and RUE values with an increase in the growing season (GS) in SRC poplar. However, maximum RUE value was found in cereal crops as compared to SRC poplar culture (woody crop). LAI and RUE may be considered as a good estimator of biomass in woody and cereal crops.
