ABSTRACT The elemental concentration of K, Na, P, Ca, Fe, Mg, Cu, Zn, and Mn was determined in seeds of three cultivars of cowpeas [ Vigna unguiculata (L.) Walp.] treated with 0, 2000, and 4000 ppm simazine as a foliar spray and side dressed with 0, 30, and 60 kg/ha ammonium nitrate fertilizer. The element Ca was increased by the simazine treatment in‘Pinkeye Purple Hull’and Mn was increased by the ammonium nitrate fertilizer treatment in‘Mississippi Silver’. Significant fertilizer by simazine interactions were found with the remaining elements. Similar treatment responses in the elemental concentration were found among the three cultivars. The percentage recommended dietary allowances based on the individual elemental concentrations that a 100s raw edible portion of cowpeas would supply were not significantly affected by the treatments.
