Journal Article 1994

Autor: Sanginga, N. Danso, S. Zapata, F. Bowen, G.

Identification of tree species or cultivars/provenances that are tolerant to low levels of available soil P will decrease the dependence on P fertilizer for the good establishment and growth of N2-fixing trees. The effects of phosphorus uptake and use efficiency on N2 fixation and growth of prove...

Autor: Okogun, J.A Sanginga, N.

Promiscuous soybean lines have been bred on the basis that they would nodulate freely without artificial inoculation. However, our recent studies have demonstrated that the indigenous rhizobia are not able to meet their full nitrogen (N) requirement. Rhizobia inoculation might be necessary. We ex...

Striga hermonthica (Del.) Benth. is an obligate, root-parasitic, flowering plant that limits cereal production in sub-Saharan Africa.Successful control depends on eliminating its seed reserves in soil, thereby preventing parasitism. Striga hermonthica seeds germinate only if adequately conditione...

Cutting and carrying of mulch from established tree plots is an alternative to in situ mulch in agroforestry systems. Through the cut-and-carry method, the undesirable e ects of tree-crop competition characterized by in situ mulching can be avoided. An economic evaluation of the cut-and-carry met...

It has been difficult to explain the rotation effect based solely on N availability in maize-soybean cropping systems in the moist savanna zone of sub-Saharan Africa. Although arbuscular mycorrhizal fungi (AMF) can contribute to plant growth by reducing stresses resulting from other nutrient defi...

Autor: Nwoko, H. Sanginga, N.

As the production of grain and herbaceous legumes is often limited by low levels of available P in moist savanna soils, the potential for managing arbuscular mycorrhizal fungi (AMF) by selecting lines or accessions dependent on AMF as a strategy to improve plant P nutrition and productivity is re...

The potential of alley cropping systems supplied with a limited amount of fertilizer to restore crop productivity on a degraded site and to maintain crop productivity on a recently cleared, non-degraded site on ‘terre de barre' soils in Southern Bénin was investigated from 1994 to 1996. Leucaena ...

Establishment of Leucaena leucocephala was poor at Ibadan (Transition forest-savanna zone) and Fashola (savanna zone, 70 km north of Ibadan) in southwestern Nigeria as a result of low soil fertility and the presence of only a few native rhizobia capable of nodulating it. Inoculation with L. leuco...
