The difficulty is that sorghum plants with extra space respond by producing more shoot branches, known as tillers. Those extra tillers use water early in the season, before grain filling, and
Every gram of synthetic nitrogen fertiliser comes at a cost of energy, money, and carbon emissions. Over the past 50 years, this natural process has been overshadowed by industrial production and use of industrial fertilisers, which have become essential for food security but undermine environment and human health. There is a pressing need to explore more sustainable solutions that can
