objective	IMPAC3 - Novel genotypes for mixed cropping allow for IMProved sustainable land use ACross arable land, grassland and woodland
content	Mixed cropping systems have the potential to enhance production by improving resource use. A field experiment was established where 8 different Populus-hybrids (focal plant species A) and 3 different Robinia clones (mixture plant species B) were established as monocultures and in varying mixtures. The main target of this subproject is to assess the impact of intra- and interspecific competition on biomass production and resource use. Repeated measurements of root collar diameter, tree height, crown structure and leaf-area-index will be carried out, and trees will be harvested for biomass estimation and the development of allometric functions.
