E. J. Allen; M. G. Barker The Journal of Agricultural Science 1972. doi:10.1017/s0021859600087694

Other claims from this paper (11)

Intervention effect Barley yield did not differ among cultivation methods with chemical weed control.
Intervention effect Without chemical weed control, deeper cultivation produced higher barley yield than discing late in the experiment.
Intervention effect Ploughing generally produced the highest wheat yields.
Intervention effect After ley, rotary cultivation produced higher wheat yields than cultivating or discing.
Intervention effect Discing gave relatively low wheat yields, particularly with cultural weed control at lower fertility.
Intervention effect Ploughing produced higher sugar yields than cultivating or discing in all rotations.
Intervention effect Rotary cultivation matched ploughing for sugar-beet yield in the second rotation, but did not consistently exceed cultivating or discing in the others.
Intervention effect Discing without chemical weed control markedly reduced sugar-beet yields in the last rotation.
Intervention effect Ploughing produced the highest potato yields.
Intervention effect Potato yields did not differ consistently among the other cultivation methods.
Recommendation The authors concluded ploughing was the more reliable seedbed preparation method.
