evaluated field performance of a
conventional row crop seeder with two types of coulter attach-
ment (plain/notched coulters) in two tillage systems (mouldboard/
chisel ploughs) for maize cropping after a wheat harvest. Chisel
ploughing followed by a coulter-seeder appears to be a good
alternative to a more conventional cropping system, offering
advantages for conservation farming and better plant establish-
ment.
