Zinc Fertilization Strategies for Enhanced Rice Production in Tanzania

The study evaluates zinc fertilization strategies to improve rice yield in Tanzania’s Kilombero district. Field trials compared Zn sources, rates, and application methods under rain-fed and irrigated conditions. Soil-applied ZnSO. and foliar ZnSO. within a NPKS fertilizer blend were most optimal in terms of yield and in addressing the issues of widespread Zn deficiency and food security. A participatory approach enabled researchers and farmers to work together and collect data and observe rice performance under different zinc and microbial fertilizer rates and regimes in Kisawasawa village, Kilombero District, Tanzania.
