Abstract

Trials were conducted on the Research farm of the Institute for Agricultural Research, Ahmadu Bello University, Samaru, Zaria in the Northern Guinea Savanna (NGS) Zone of Nigeria in 2010 and 2011 wet seasons to evaluate the reaction of Alectra vogelii to botanicals and the performance of cowpea varieties under Alectra vogelii Benth infestation. In all the trials, SAMPEA 6 exhibited tolerance by combining support for high emergence of Alectra with the production of high cowpea grain yield. Vigna unguiculata,Kanannado, a Local cowpea variety supported low parasitic weed infestation and produced comparable grain yield than the recommended cowpea variety SAMPEA-7. Treating planting holes with Azadiratha indica seed powder, Azadiratha indica leaf powder, Eucalyptus spp leaf powder, Anacadium occidentale L. leaf powder, Tamarindus indica L. leaf powder and Carica papaya L. leaf powder delayed Alectra emergence, reduced Alectra count and number of plants infested, reduced crop reaction score, took longer days to 50% flowering and gave higher cowpea seed yield.
