Assessment of farmers' crop management practices influencing Striga hermonthiea infestation and grain yield of sorghum (Sorghum hieolor) por Dugje, I.Y., Kamara, A.Y., Omoigui, L.O.

“…Relay intercropping reduced grain yield ha-1 (r = -0.52*) in· northern Guinea savanna, but sorghum-legume rotation, weeding frequency, and increased nitrogen fertilizer rate increased grain yield as these were positively associated with grain yield ha-1 in both zones. In Sudan savanna, Slriga counts were reduced by relay intercropping of sorghum with legumes, as the practice was negatively associated with Striga count, while inadequate weeding promoted infestation (r = 0.44*). …”
