Short and longterm maize yield response to Mucuna pruriens and Pueraria phaseoloides relay fallow and biomass burning versus mulching in the forest zone of Southern Cameroon
Maize was relay cropped with the cover crops Mucuna pruriens or Pueraria phaseoloides for between one and seven consecutive years in three sites: Ngoungoumou, located in an area of low land use intensity (LUI), about 100 km away from the next major market, and at Evendissi and Andok, in a medium LUI...

| description | Maize was relay cropped with the cover crops Mucuna pruriens or Pueraria phaseoloides for
between one and seven consecutive years in three sites: Ngoungoumou, located in an area of low
land use intensity (LUI), about 100 km away from the next major market, and at Evendissi and
Andok, in a medium LUI area, 15 to 20 km away from the next major market. Maize performance
was compared with that in a natural fallow system, with fallow biomass burned versus retained
as mulch in both fallow types. Fallow type had no effect on maize density. After biomass burning
higher maize densities were attained at the low LUI site. Maize cob production was affected
neither by fallow type nor by biomass management. Across seven years of cropping, marketable
cob production in the low LUI site was 38.5% higher in mucuna fallow than in natural fallow
(p < 0.06). Differences at p < 0.05 were found in one out of seven years. In the medium LUI
sites, mucuna and pueraria fallow increased marketable cob production by 70–132% (p < 0.001).
Maize grain yield was closely related to the marketable cob production in all sites. In the low
LUI site the cumulative maize grain yield over seven years was 30% higher in mucuna fallow
than in natural fallow (p < 0.07), the difference being significant at p < 0.05 in only one year.
In the medium LUI sites maize grain yield was 65% higher in mucuna fallow (p < 0.001) and
69-94% higher in pueraria fallow (p < 0.001). Burning biomass had a cumulative grain yield
advantage of 33% at the low LUI site (p < 0.053), with significant (p < 0.02) differences in two
out of seven years. Biomass burning had no effects on maize grain yield in the medium LUI sites.
No interactions between fallow type and biomass management were found. Despite the lack of
frequent significant advantages of the cover crop fallows in the low LUI site, the system can be
recommended because it has the potential to increase food diversity and security; in the medium
LUI sites farmers were immediately convinced of the benefits of the system and have since moved
on to grow high value vegetable crops. |
