Researchers at UGent have found ways to efficiently grow organic frozen spinach, a crop that is in high demand but poses challenges due to difficult weed control and strict quality requirements. The research indicates that increasing the stand density and reducing the inter-row distance can significantly decrease weed biomass and increase spinach biomass. Additionally, post-emergence weeding and a false seedbed can also help reduce weeds. These findings are expected to provide maximum harvest security and reduce the chance of rejection by the industry. The research contributes to the European Green Deal, which aims to have organic farming on 25% of all agricultural land by 2030. The thesis received the Thesis Prize Organic and agro-ecological agriculture and food 2020.
