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.
