摘要

The use of leguminous cover plants to suppress weeds in plantation crops dates back to many decades, but the integration of the legumes into arable cropping systems has not been developed to a level acceptable to farmers. Five legume cover crops (Pueraria phaseoloides (Roxb) Benths, Stylosanthes guianensis (Aubl.) Sw., Mucuna pruriens (L.) Dc var. utilis Wall ex Wight, Mucuna preta and Mucuna jaspeada] with a no legume cover as control were used as a sub-treatment in an integrated weed management in maize/cassava intercrop. The study was carried out at the Teaching and Research Farm of the University of Ilorin in 2002 and 2004. Significantly lower weed densities were obtained under S. guianensis and M. pruriens var. utilis (7.83 and 8.08 weeds/m2, respectively) compared with densities in P. phaseoloides (9.87 weeds/m2), M. jaspeada (9.37 weeds/m2) and M. preta (11.71 weeds/m2) plots at 12WAP. Mucuna preta produced the highest ground cover at 10WAP while M. pruiens (var utilis) had the highest ground cover at 16WAP in 2002. In 2004, M. jaspeada produced the highest ground cover at both 10 and 16WAP (59.6 and 91.0% respectively). Total weed density was significantly reduced under S. guianensis and M. pruriens var. utilis at 48WAP in 2004. There was no significant difference in the yield of maize in the various legume cover crops plots in both years while average yield of fresh cassava tuber was significant in M. preta plots.
