Adimaitoga’ s Research Topic: “Assessing the Development and Quality Characteristics of Melrose Tomato (Solanum lycopersicum L.) Under Waterlogging Conditions in Western Fiji”

“This study explores the profound impact of climate change on agriculture, focusing on the resilience of tomato cultivation—a vital crop for economic and social development. Conducted over seven months in Lautoka Fiji, the research investigated the effects of waterlogging on Melrose tomatoes (Solanum lycopersicon L.) in a controlled greenhouse environment. The study explored how varying waterlogging depths (subsurface, ground level, and submergence) and durations (24, 48, and 72 hours) impact key growth metrics, fruit yield, and quality attributes such as sweetness (brix) and lycopene content. The findings reveal that while moderate waterlogging can enhance certain traits, prolonged exposure significantly reduces yield and quality. These insights inform strategies for off-season farming, including greenhouse cultivation, cultivar selection, and optimal soil and water management, optimizing tomato cultivation in regions prone to climate-induced waterlogging. This project was made possible by the DevNet Pacific Development Research funding and the Fiji National University Natabua campus research facility.”
