Abstract:
Two intercropping trials were established in 1985-1986
to compare the effects of inter-row intercropping, intra-row intercropping, and sole cropping of sorghum and groundnuts on emergency of
Striga shoots on sorghum. Intra-row intercropping reduced density of
Striga significantly when compared with sole cropping of sorghum.
This effect appeared tube soil temperature-mediated. Soil temperatures in intra-row intercropping were 2°C lower and closer to the
minimum threshold of 30 °C than in sole sorghum during the peak
period of germination
