Greenhouse studies were undertaken to determine the differential Ca absorptive capacity of peanut (Arachis hypogaea L.) fruit of 7 selected cultivars. The cultivars were selected to give a wide range in differential cultivar response to Ca fertilization. Individual fruit were grown in a beaker containing a well stirred and aeriated nutrient solution of 125 ml containing an initial 1.5 mg of Ca. Water was replenished periodically to maintain a total volume of 125 ml. At timely intervals 1 ml aliquots were removed from each beaker and analyzed for Ca. The lowest Ca concentration to which the peanut fruit reduced the Ca concentration in the solution was taken as the Ca absorption efficiency. No difference was found among genotypes for Ca absorption efficiency suggesting other mechanisms of Ca nutrition or plant utilization as the important factors in the Ca nutrition of peanut fruit.
