Abstract

Corn (Zea mays L.) was continuously cropped
in seven systems, with or without irrigation.
Baseline irrigated corn yields of 200-
210 bu/acre were reduced 65-75 bu/acre by not utilizing
standard rotational practices. The best continuous
corn yields were from systems with disking
in some phase of the operation. The only follow-crop
to consistently approach an economically attractive
level was sunflower (Helianthus annuus L.),
but continuous corn yields remained depressed in
this system. Corn yields benefitted from soybean
(Glycine max L.) as a follow-crop, but soybean itself
yielded well only 1 of 4 years. In the absence of a
follow-crop, delaying disking until immediately before
spring corn planting yielded as well as any other
treatment compared.
