The weed seed bank under seven fallow tree species was analysed in size and composition five years after tree establishment. The seed bank was lower in Enterolobium cyclocarpum fallows than in the other tree fallows at both 0-5 and 5-10 cm depths. Nuclea latifolia and Terminalia superba tree fall...


Kamara, A.Y.Chikoye, D.Jutzi, S.C.[Differences in weed seed banks in planted tree fallows in southwestern Nigeria]Differences in weed seed banks in planted tree fallows in southwestern Nigeria

Multilocational characterization of selected herbaceous and shrub legumes was carried out over a 3-yr period at lowland and midlatitude sites in the moist savanna agroecological zone in Nigeria where a south-north gradient exists for rainfall, length of growing season, and insolation. One study s...

Several insects, pathogens and weeds are serious constraints upon cassava production in West Africa. The International Institute of Tropical Agriculture and agricultural research institutions from Benin, Cameroon, Ghana, and Nigeria initiated the Ecologically Sustainable Cassava Plant Protection ...


Chikoye, D.Ekeleme, F.Ambe, J.T.[Survey of distribution and farmer perceptions of speargrass Imperata cylindrica in cassava based cropping systems in West Africa]Survey of distribution and farmer perceptions of speargrass Imperata cylindrica in cassava based cropping systems in West Africa

The influence of weeds on maize intercropped with cassava was evaluated in three fallow management systems and four cropping frequencies from 1989 to 1996 in lbadan, Nigeria, West Africa. Fallow management systems consisted of natural bush, Leucaena leucocephala hedgerows and Puerctria phaseoloid...

Field trials were conducted in 1999 and 2000 in the northern Guinea savanna of Nigeria to evaluate the potential of several weed management practices to reduce early weed competition in maize. The treatments were different combinations of the herbicide mixture metolachlor + atrazine at 5 L ha−1, ...


Chikoye, D.Schulz, S.Ekeleme, F.[Evaluation of integrated weed management practices in maize in northern Nigeria]Evaluation of integrated weed management practices in maize in northern Nigeria

Planted fallows are an alternative to the unsustainable bush fallow for improved soil and weed management in the tropics. However, the interactive effects of planted fallows and tillage on the weed seedbank are not well documented in the tropical environment. The effect of fallow type and tillage...


Ekeleme, F.Chikoye, D.Akobundu, I.O.[Weed seedbank response to planted fallow and tillage in southwest Nigeria]Weed seedbank response to planted fallow and tillage in southwest Nigeria

Speargrass, Imperata cylindrica (L.) Raeuschel, is a serious weed, threatening crop productivity in smallholder farms in West Africa. Since the use of more effective practices such as deep tillage and chemical control is beyond the means of resource-poor farmers who carry out most agricultural ac...

La concurrence des mauvaises herbes est un obstacle à la rentabilité de la production du manioc. La connaissance des espèces de mauvaises herbes qui affectent négativement la productivité du manioc est essentielle pour une gestion efficace. Une étude a été conduite entre mai et juin 2014 et 2015 ...
