Four maize cropping systems 1990-1993: weed development and ground cover

Weed development and the ground cover by live mulch were different in the four cropping systems: in the conventional ploughed system, using chemical weed control, some potentially triazine-resistant weeds remained. The system using mechanical weed control and with grass/trifolium underseed offered a...

Summary:Weed development and the ground cover by live mulch were different in the four cropping systems: in the conventional ploughed system, using chemical weed control, some potentially triazine-resistant weeds remained. The system using mechanical weed control and with grass/trifolium underseed offered a good weed control. Rotary band-tilled maize in a flail-chopped rye using row crop spraying and with single mulching between the rows resulted in too high weed infestation but allowed full nitrate retention before maize sowing, and erosion control. Rotary band-tillage in a trifolium/grass sward with two to three mulching procedures between the maize reduced weed production. Permanent live mulching offered an overall nitrate retention and full erosion control
