Abstract
Experiments were conducted on maize/cowpea intercrop at the Research Farm of the Institute for
Agricultural Research, Ahmadu Bello University Zaria, (110 111 N 380 E) in the Northern Guinea
Savanna of Nigeria. Samples of weeds were collected to assess the occurrence and severity of
noxious weeds and other broad leaved weeds. Eragrotis ciliaris, Eleusineindica and
Rottboelliaco chinchinesis were widely spread in the three years of the study (2010, 2011 and
2012). The incidences were generally higher in 2012 in all cases. Striga gesneroides, Alectra
vogelii and Cuscuta australis were found in all the blocks and they increased on yearly bases.
Generally, across board, weed infestation increased on yearly bases.
