AB  - This dataset contains the yields of hay (t/ha), for both the 1st and 2nd cuts, harvested from Park Grass Hay Experiment since 1965-2018. Details of the fertilizer, lime treatments and harvest dates are also included. In 1965, a new liming regime was introduced with four sub-plots per plot (a. at pH 7, b. at pH 6, c. at pH 5 and d. un-limed). Yields are provided for all fertiliser treatment plots and sub-plots (except for plots 5 and 6 cd, which were used for micro-plot experiments). Yields are expressed as t/ha at 100% dry matter. Variations in yield reflect the various fertilizer treatments and liming regimes, as well as the local weather and atmospheric inputs.
