Micronutrient Assessment of Cocoa, Kola, Cashew and Coffee Plantations for Sustainable Production at Uhonmora, Edo State, Nigeria

The micronutrient status of the soils and leaf of cocoa, kola, cashew and coffee plantations to study the soil-plant micronutrient content relationship in the plantation soils for proper management towards optimum production of the crops was investigated at Uhonmora, Edo State, Nigeria. Soil and leaf samples were collected from these plantations and analyzed according to standard laboratory procedures. The soil samples were analyzed for the micronutrients (Cu, Mn, Zn and Fe) and in addition pH, organic carbon, sand, silt and clay contents, while the leaves were analyzed for only the micronutrient contents. Results indicated that the soils were sandy loam, acidic, low in organic carbon, deficient in Cu and Mn but very high in Fe and Zn contents. This probably resulted in nutrient imbalance in the soils and the deficiency of the nutrients in the crops. The plantations therefore require application of organic manures and micronutrient fertilizers to rectify the inadequate soil organic matter and to supply sufficient amount of Cu and Mn in the soils, to obtain quality fruit yield at optimum level from the plantations.Keywords: Cashew, cocoa, coffee, kola, micronutrients, sustainable production [How to Cite: Ogeh JS and RR Ipinmoroti. 2013.
