Which cropping system is more productive and/or most uses the sun’s radiation most efficiently?

In this paper Project 1 provides a thorough comparison of novel perennial grasses and annual crops in cropping systems optimised for biomass supply to a biorefinery, and compares them to traditional cropping systems.

The article “Biomass productivity and radiation utilisation of innovative cropping systems for biorefinery” is published in Agricultural and Forest Meteorology. The aim of the work was to determine biomass yield and associated radiation utilisation for novel perennial grasses and annual crops in rotations optimised for biomass production, and compare their performance with traditional cropping systems commonly used in northern European agriculture. Measurements of biomass yield from 2012 to 2015 at two Danish sites were conducted in three main cropping systems, and measures to determine the radiation use efficiency (RUE) were determined from canopy radiations biweekly for three years.
