Isoflavones in Pueraria mirifica act as phytoestrogens in mammals. The estrogenic activity of Pueraria mirifica is rather more potent than that of soy isoflavones. The potential of planted leguminous cover crop fallow instead to the pure regrowth fallow for sustaining the productiveness of low exercise clay (LAC) soils within the tropics as the fallow interval shortens was tested at Ibadan within the forest-savanna zone of southwestern Nigeria. Pueraria phaseoloides, an herbaceous, N-fixing, perennial legume with a gradual preliminary progress behavior, was chosen as a take a look at cover crop. Integration of a pueraria legume cover crop did not have an effect on soil pH. Cowl crop-fallow maintained soil organic carbon standing better than the natural fallow. The research, initiated in 1990, compared an improved system (cover crop-fallow) and a standard system (natural fallow), with the purpose of creating an improved cowl crop-fallow system for sustainable management of LAC soils of the tropics.

Outcomes point out cover crop-fallow with pueraria might be a greater various to traditional natural fallow underneath shortened fallow periods for elevating or maintaining productiveness of LAC soils of the humid tropics. Cover crop-fallow resulted in a 22 to 72% higher maize yield than the pure fallow from 1992 to 1996. Although in 1992 and 1994 cassava tuber yield was decrease with the cover crop-fallow than with the pure fallow, with higher pueraria husbandry in 1996, cover crop-fallow elevated the cassava tuber yield by 41%. With residue burning, the N stability was 27 kg N ha-1 yr-1 for the pueraria cowl crop-fallow system and -15 kg N ha-1 yr-1 for the chromolaena natural fallow system.
Pueraria produced 253 kg N ha-1 after the fallow period, in contrast with 109 kg N ha-1 for chromolaena; pueraria was also better in recycling P (eleven kg P ha-1) than was chromolaena (9 kg P ha-1).
Natural fallow for 1 12 months elevated the maize yield from 75 to 350% from 1992 to 1996, and the cassava yield from 9 to 130% in contrast with steady cropping. In a 2-yr cycle, 1 yr of cropping was adopted by 1 12 months fallow with pueraria for the cover crop-fallow system or with natural regrowth (mainly Chromolaena odorata) for the pure fallow system. Maize-cassava intercropping and not using a fallow interval (steady cropping) was included as a management.
