Impact of Witch Weeds (<i>striga hermonthica</i>) on Sorghum Production and Its Managements in Ethiopia

Striga hermonthica (Del.) Benth is a major constraint to sorghum productivity. Striga can cause small percentage loss in yield and, some situations, complete crop collapse. resistant sorghums be valuable component if resistance built into well-adapted and productive cultivars. Sorghum's potential output has been diminished due variety of abiotic biotic stresses. Abiotic stressors like as drought low soil fertility (nutrient deficit) are two the most common. Parasitic animals expected cost world £1.5 trillion every year. Heterotrophic flowering plants that may cling their host known parasitic weeds. Haustorium acts physiological link between parasite plant it parasitizes. genus Orobanchaceae hemiroot parasites includes roughly thirty species. photosynthesizing obligate hemi-parasite. found Africa, Middle East, Asia, Australia tropical semi-arid climates. root-parasitic, annual, chlorophyll-bearing require life cycle. seeds produce 100,000 200,000 per plant, but they must pretreated stored moist, warm environment (300C germination). Over course its 20-year existence, ability thousands seeds. If chemical cue released by plant's roots, germinate. Therefore purpose this review paper assess influence witch weeds (striga hermonthica) on production management’s methods.
