Two crops or one? Sometimes, growing two crops simultaneously on the same piece of land – called intercropping – can benefit farmers. But it needs careful planning and resource management.
In some parts of Africa, farmers intercrop sorghum – a grain – and peanuts. But they face a major information gap. There hasn’t been much research on optimal levels of fertilizer use for intercropping sorghum and peanuts in these areas.
A new study has filled this information gap. Researchers from Niger, Mali, and the United States have developed a method to help farmers determine how much fertiliser to apply when intercropping.
Trees may be easy to spot on the plains of Africa but they are often overlooked as a source of income for farmers. A University of Illinois (USA) study shows trees on farms may help reduce rural poverty and maintain biodiversity.
