Woburn Intensive Cereals

  • Experiment Code: W/RN/13
  • Experiment Site: Woburn
  • Objectives: To study the effects of intensive cereal cropping on yield, incidence of soil-borne pathogens and organic matter in the soil.
  • Description: On Woburn Stackyard I field, on the site of the previous Woburn Continuous Wheat and Barley experiments (W/XW/6 and W/XB/6). An experiment comparing winter wheat and spring barley grown continuously and in rotation was started in 1967. A five-course rotation of 1-year grass ley, potatoes and three years of either wheat or barley.
  • Date Start: 1966
  • Date End: 1990

Experimental Design

Description

  • 2 blocks of 6 whole plots each split into 4 sub-plots (8 in certain years). Wheat in one block, barley in the other. Sub-plots received 4 N rates. Sub-sub-plots received with and without MgO as Epsom salts (wheat only).

Design

  • Period: 1966 - 1990
  • Number of Blocks: 6
  • Number of Replicates: 1
  • Number of Sub-plots:
  • Number of Harvests per Year: 1
