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.
Legumes are a very special type of crop; they are not only a source of highly nutritious food and feed but legumes require no inorganic nitrogen fertiliser, which means they have major advantages as a more sustainable crop. Despite their benefits, legume-based farming systems have not become common practice as they are seen as being less profitable.
According to recent media reports the European Commission seems poised to ban some of Europe’s most widely used pesticides to protect bees and other pollinators, but is the move likely to have an impact on food production and security? Scientists at the James Hutton Institute have demonstrated that many farmers can reduce agrochemical inputs by using alternative pest control methods without reducing yield or quality.
