Woburn Continuous Wheat
- Experiment Code: W/XW/6
- Experiment Site: Woburn
- Objectives: To test the effects of fertilisers and manures on the growth of continuous winter wheat
- Description: This experiment is almost identical to the Broadbalk Wheat experiments at Rothamsted, but at Woburn. It started in autumn 1876, on Woburn Stackyard field. There is a parallel experiment on Continuous Barley which started in 1877, with the same plot numbers. The experiments were carried out by the Royal Agricultural Society of England (RASE) but with input from Lawes.
- Date Start: 1876
- Date End: 1966

Description
- Same design as the Woburn Continuous Barley Experiment. Plots divided into four groups according to previous fertilizer and manure treatment in Period 1. Each group of plots received fertilizer N (39, 78, 118 kgN/ha) over a three year cycle. Plots 1, 3, 7 (previously no P or K); Plots 4, 6, 9 (previously PK); Plot 11b (previously FYM); Plots 10a, 10b, 11a (various treatments).
