摘要：

The effect of broadcast or band-placed application of fertilizer on the growth of weeds was studied at two locations on low-fertility acid soils in Suriname. Band placement of fertilizers considerably reduced weed growth compared to fertilizer-applied broadcast. With band-placed fertilizer the increased weed growth due to fertilizer application was concentrated on the fertilized bands. Weed growth was also stimulated in planter wheel-tracks. The spatial distribution of the weed growth is discussed in relation to the crops groundnut, sorghum and soybean, grown at the same location.
