    EFFECT OF SUBSTRATE AND FERTILIZER APPLICATION ON MICRO MINERAL CONTENT OF Zea mays IN A SOILLESS FARMING SYSTEM

    ABSTRACT This study was conducted at the Federal University of Agriculture, Abeokuta (FUNAAB), Ogun State, Nigeria, to evaluate the effects of different substrates and fertilizer application rates on the micro-mineral content of Zeamays in a soilless farming system. The experiment utilized a 3 × 3 factorial design with substrates (coco peat, rice husk, grow mix) and fertilizer rates (0, 120, 240 kg/ha). Data were analyzed using two-way ANOVA. The results showed that substrate choice and fertilizer application significantly impacted manganese (Mn), zinc (Zn), and iron (Fe) content. Rice husk was most effective for Mn and Zn, while coco peat enhanced Fe levels. The interaction between substrates and fertilizer rates highlighted the need for balanced nutrient management to optimize micro-mineral content, with excessive fertilization potentially reducing copper (Cu) levels. In conclusion, rice husk is recommended as the primary substrate for Zeamays in soilless farming to optimize Mn and Zn content, while coco peat is suggested for Fe enrichment. A fertilizer rate of 240 kg/ha is recommended, though careful calibration is advised to avoid reductions in Cu levels. Future studies should investigate the long-term effects of these substrate-fertilizer combinations on plant health and yield.
