Dataset: Woburn Ley-arable experiment: yields of wheat as first test crop, 1976-2018


Annual grain yield for the winter wheat test crop, on the Woburn Ley-Arable experiment, 1976-2018, with treatment details.


The Woburn Ley-arable experiment was started in 1938, to compare the effects of different rotations, with and without grass or grass/clover leys, on soil organic matter and the yield of two arable test crops. 'Test crop' refers to a major cash crop on which the effects of the different arable rotations and leys were assessed. The rotations are typically three years of 'treatment crops' followed by two years of 'test crops' (the exception are the eight-year ley treatments). The two test crops have changed throughout the experiment, and the first test crop has been wheat since 1976. This dataset contains the yield of wheat grown as the first test crop, 1976-2018, plus details of the N fertilizer treatments, basal fertilizer, sowing and harvest dates.

Technical Information

Wheat grain yield at harvest at 85% dry matter content. Winter wheat was grown every year, except for 2015, when the spring wheat variety Mulika was sown, as the winter wheat crop failed.
