Corn and straw yields at the agroforestry site Forst, Brandenburg starting 2019

Barley (Hordeum vulgare) and bristle oat (Avena strigosa) were harvested at the agroforestry site in Forst and the reference site on July 25th, 2019, and July, 30th 2020, respectively. After plots were harvested using a plot combine harvester subsamples were oven dried for 24 hrs at 105°C to determine water content and dry weights of the samples. The table contains the fresh weights of the harvested barley and bristle oat corn and straw biomass, the weights of the subsamples before and after oven-drying, the weight of the containers used for oven drying as well as the corn and straw dry weight yields in t/ha calculated from these parameters.

Research question: Does crop productivity differ at agroforestry sites vs. treeless reference sites?
Within the agroforestry site, are crop yields different at different distances to the tree rows?
