| dc.description.abstract | Soil population densities of Helicotylenchus multicinctus (Cobb) Golden were assessed under
Flemingia macrophylla [(Willd.) Merrill] and Pueraria phaseoloides (Roxb.) Benth, and natural
bush fallows over 24 months in three villages in southern Cameroon. Also assessed was the effect
of H. multicinctus on yield of plantain. Trials were set up in four to five year-old Chromolaena
odorata (L.) R. M. King & H. Rob. dominated natural bush fallow. Initial H. multicinctus
population density at Ngoumou (512 100 cm–3 soil) was (p < 0.05) higher than at Mfou (241
100 cm–3 soil) and Nkometou (70 100 cm–3 soil). H. multicinctus population was correlated with
(i) total annual rainfall (r = 0.79; p = 0.01) and (ii) clay content (r = 0.95; p < 0.001). At 12
months after planting (MAP), P. phaseoloides and F. macrophylla supported (p < 0.01) lower
population densities of H. multicinctus (88 and 152 100 cm–3 soil, respectively) compared with the
natural regrowth (287 100 cm–3 soil). Comparing the initial population with that at 12 MAP for
each of the three fallow systems, both P. phaseoloides and F. macrophylla reduced density of H.
multicinctus (p < 0.05). However, when the initial population density was compared with that at
24 MAP only under P. phaseoloides was the reduction maintained. Contrarily, population density
under F. macrophylla was comparable between the initial and 24 MAP. This is the first report of
the nematode reducing effect of P. phaseoloides. Plantain flowering and subsequent harvesting was
earliest under P. phaseoloides, different from that under F. macrophylla (p < 0.05). Plant bunch weight was positively correlated with the length of the fruit filling period (r = 0.67) which in turn
was positively correlated with the non damaged root index (NDRI) (r = 0.58). Plantain under P.
phaseoloides had the highest NDRI and consequently recorded the greatest yield (p < 0.05). There
was no difference in plantain yield between the natural regrowth and F. macrophylla. Pueraria
phaseoloides could be used as one component for the biological control of H. multicinctus. |
