Author: Ian Tarbotton Source: [original](http://www.cs.waikato.ac.nz/ml/weka/datasets.html) - Please cite: White Clover Persistence Trials Data source: Ian Tarbotton AgResearch, Whatawhata Research Centre, Hamilton, New Zealand The objective was to determine the mechanisms which influence the persistence of white clover populations in summer dry hill land. In particular reference to the consequence of a severe summer dry period in 1993/1994 and how it impacted on the performance of three white clover cultivars in an on-going experiment located at Whatawhata Research Centre. The machine learning objective was to predict the amount of white clover in 1994 from the amount of white clover and other species in the years 1991 to 1994 as well as information on the 'strata' where the white clover was being grown. Attribute Information: 1. strata - enumerated 2. plot - enumerated 3. paddock - enumerated 4. WhiteClover-91 - white clover measurement in 1991 - real 5. BareGround-91 - bare ground measurement in 1991 - real 6. Cocksfoot-91 - cocksfoot measurement in 1991 - real 7. OtherGrasses-91 - other grasses measurement in 1991 - real 8.
