Heavy infestation by the root parasitic sunflower broomrape over wide regions constitutes a major biological constraint to sunflower production. The use of maize as a trap crop to induce sunflower broomrape germination is considered a cost-effective method for controlling sunflower broomrape. This study was designed to examine the activity of maize to induce sunflower broomrape seeds germination under varying levels of nitrogen (N) and phosphorus (P) fertilization. Orthogonal experiments were conducted during two cropping seasons...
