On 14/8/2020 researchers from Department of Soil and Geological Sciences, SUA under the project titled “Nitrogen Bio-Fortified and Pelletized Commercial-Grade Organic Fertilizer Made from Urban Bio-waste to Improve Soil Productivity and Livelihoods of Small Holder Farmers” visited demonstration farm at Ruaha-Mbuyuni in Iringa to assess and evaluate onion growth performance. Onion in demonstration farm was found growing well as shown in Plates 1 & 2. Also researchers discussed with the onion champion farmers on the challenges they are facing. It was revealed that most onion farmers at Ruaha-Mbuyuni are applying fertilizers to their soils without knowing their fertility status. They were advised to analyse the soils in their farms at least once after two years. This will enable them to apply the right amount of fertilizers and avoid using a lot of fertilizers unnecessarily. This will assist them to serve money of buying unnecessary amounts of fertilizers and thus, to obtain more profit from what they are producing.
