As the original design of the Eothamsted Experiments embraced all the crops of the farm, so essential a feature of English farming as the root-crops naturally occupied a prominent place; indeed we find that the second paper of experimental results issued from Eothamsted in 1847 dealt with turnip culture. In 1843, accordingly, the Barn field was set aside for experiments on turnips, the trials being on Norfolk white turnips for six seasons, 1843-1848, followed by.
