Summary
This work was designed to study the effect of the intensity and width of inter-row tillage on the yield of the potato crop.
Soil mulch appeared to have no effect on yield.
Inter-row tillage benefited the crop although it restricted the growth of weeds only, and did not create soil mulch.
It is not of any value to potato yields to carry on with cultivation more than twice.
Narrow inter-row tillage (tines 8 inches from the plant) benefited the yield more than wide inter-row tillage (tines 6 inches from the plant). This held true in Kerr’s Pink, although it does not apply in the case of the Red Skin variety, because the lateral spread of the root system is greater in the case of Kerr’s Pink.
