Example yields derived from the data. Fallow (no crop grown) in missing years

Summary

Annual grain and straw yields for all plots and sub-plots on the Woburn Continuous Barley Experiment, 1943-1966, with details of N fertilizer applied, and other agronomic information, including sowing date, plot size and cultivars. Spring barley was grown every year until 1961 (apart from fallow years), then oats (1962) and spring beans (1964). The whole experiment was fallowed to control weeds (no crop sown) 1947-1949, 1956, 1957, 1963, 1965 and 1966. This experiment is a companion to the Woburn Continuous Wheat experiment.

Methods

The Woburn Continuous Barley Experiment started in 1877, with a range of fertilizer and manure treatments applied until 1926. No fertilizer was applied 1927-1940. From 1943-1955 the plots were divided into sets of three, according to their past fertilizer treatments, and three N rates were applied in cyclic order. Plots 2, 5 and 8 were fallowed and not included in the fertilizer N trials, as they were so acidic (due to the fertilizer treatments applied in 1877-1926). No other fertilizer or manure was applied. The plots were divided in half in 1952 and 1953 to compare winter and spring-sown barley, and in 1959-1961 to compare spring barley and wheat. Microplot experiments were made on some plots in 1960-64; this data is not included. Basal fertilizer N was applied to all plots in 1959-1961 (barley and wheat) and in 1962 (oats). Lime was applied in 1955 to all plots to bring soil to about pH 6. Further lime was applied to selected areas in 1956-1959. In autumn 1962 the whole area was limed to bring to about pH 7.

Technical Information

Grain and straw yields at 85% dry matter. Straw yield does not include the stubble or all of the chaff. Fallow (no crop) yields shown as a blank cell. The plots were divided into sets of three according to their fertilizer treatment in 1877-1926 for the N fertilizer treatments, 1943-1955:

• No P or K Plots 1, 3, 7
• PK Plots 4, 6, 9
• FYM Plot 11b (divided into three sections, 1, 2 and 3)
• Various treatments Plots 10a, 10b and 11a
• Plots 2, 5 and 8 were not included in this scheme and no yields were taken until 1955. Lime applied to all plots in 1955 to bring all plots to about pH 6.0.
