Plants Profile for Striga hermonthica (purple witchweed).
Four species, namely Striga asiatica (L.) Kuntze (syn. S. lutea Lour.), Striga hermonthica Hemsley and Skan, Striga hermonthica (Del.) Benth. and Striga forbesii Benth. are important in the region. S. asiatica occurs in most countries particularly on poorly drained soils with a low nutrient content whereas S. hermonthica and S. forbesii develop mostly in specific areas of Tanzania and Zimbabwe.
A study of Striga hermonthica problems was carried out in Benin during 1993-1996 with a view to improving the traditional Striga control methods and obtaining a better knowledge of the germination ecology of S. hermonthica. Striga spp., in particular S. asiatica, S. gesnerioides and S. hermonthica, are considered a major biotic constraint on food production in sub-Saharan Africa, seriously.
Eleusine coracana, or finger millet, is an annual herbaceous plant widely grown as a cereal crop in the arid and semiarid areas in Africa and Asia.It is commonly called kodo in Nepal where 877 accessions have been maintained by National Plant Genetic Resource Centre, Khumaltar, Nepal. It is a tetraploid and self-pollinating species probably evolved from its wild relative Eleusine africana.

The choice of Striga hermonthica as the parasite is linked to its economical importance world-wide and the expertise in our group. Moreover in this way the project will be embedded in an intensive ongoing collaborative research effort with a number of national and international institutes in West Africa.Field, pot and laboratory studies will be used to quantify relations between major.
Assessment of the relationship between soil properties, Striga hermonthica infestation and the on-farm. It also assessed the relationship between soil properties, Striga infestation and the yields of maize. 2. Materials and methods 2.1. Sampling procedure. A field survey was carried out in October 2011 in five selected Local Government Areas (LGAs) each of Kano and Bauchi States in the dry.
Classification Essay Classification is the process of grouping together people or things that are alike in some way. A simple classification would be to classify cars in terms of their body size: full-size, mid-size, compacts, and sub-compacts, or Portland Community College in terms of its different campuses. These groups or categories, are helpful in letting you see relationships among people.
