摘要

Lablab (Lablab purpureus) is a dual-purpose legume with the potential to be incorporated into the smallholder maize monoculture system which predominates in the Limpopo Province of South Africa. Thirty-three introduced accessions and three local plant types were evaluated in a fanner's field near Polokwane during the 2002/03 growing season for agronomic characteristics, biomass production and grain yield. Days to 50% flowering ranged from 51 to over 150 days and days to maturity ranged from 90 to 197 days among the entries. Approximately 50% of the accessions produced between 1000 and 5000 kg/ha of total biomass at 87 days after planting (DAP), with two of the entries producing over 7000 kg/ha. The maximum grain yield obtained was between 500 and 600 kg/ha, produced by about 14% of the accessions. Generally, the early flowering and maturing types produced the highest grain yields. This diversity in growth characteristics suggests potential for lablab to be a multi-purpose crop for use in the smallholder systems of South Africa. Further on-farm evaluation in partnership with farmers is suggested as the next step in testing promising accessions of lablab.
