An interaction between macro and micronutrient in crop production is indirectly related to the yield components. An experiment was carried out between June and September 2009 at the National Horticultral Research Institute (NIHORT) to characterize and assess the interaction among macro and micronutrient in the production of Okra (Abelmoschusesculentus). Sixty two accessions of Okra were arranged in a randomized complete block design with three replicates. The most recently matured whole leaf with petiole were harvested thirty days after sowing for tissue analysis. Correlation analysis was carried out between the leaf macronutrient concentration and micronutrient concentration. There was significant positive correlation beweenNitrogeen and Calcium, Magnesium, Potassium, Manganese, Iron, Copper and Zinc. The correlation coefficient ® values for these relationship ranges from 0.02-0.25 indicating an increase in the leaf Nitrogen concentration results in an increase in the concentration of Ca, Mg, K, Mn, Fe, Cu and Zn. Interaction between nutrients was therefore established among the macro and micronutrient of the 62 okra lines.
