- Abstract:
- Alectra vogelii is noxious parasitic weed of legumes especially groundnut in Nigeria that has lead to great losses in the quantity and quality of groundnut produced in Nigeria and other West African countries. Aim: This research was conducted in order to determine the effects of Alectra on leaf mineral contents of different groundnut varieties used in Nigeria. Methods: Field trail was conducted in the wet seasons in 2005 and 2006, to determine the effects of Alectra vogelii a parasitic weed, on the leaf mineral elements concentration in 15 groundnut varieties at 7 and 9 WAP.These varieties are UGAIO, UGAII, UGA13, EX-DAKAR, ISNIG 78, ISNIG532, ISNIG 701, RMP 91, RRB, and MS72-80. Results: The data showed that leaf potassium concentration was reduced in most varieties on Alectra inoculated plots. Most groundnut varieties exhibited increase in leaf phosphorus, calcium, magnesium and zinc at 7WAP, and decreased at 9 weeks after planting (WAP), except manganese and magnesium.UGA7, UGA9, ISNIG78 and RRB showed increased concentrations while UGA10 and UGA13 showed decreased concentrations of most elements at 7 and 9WAP. UGA2, UGA5, UGA6, UGA11, ISNIG532, ISNIG701, RMP91 and M572-80 showed a reversal of the effects at 7 and 9 WAP. Conclusion: The study showed that Alectra vogelii causes a reduction in the mineral elements content of groundnut; hence reductions in yield of the crop in Nigeria especially pod development.
