Plant Response to Manganese Source, Rate and Method of Application1

Year: 1969

Type: article

Abstract: MnSO 4 and Rayplex-Mn were found to be effective sources of Mn for tomato seedlings grown on a Mn deficient high organic sandy soil. Tomato seedlings absorbed Mn from MnSO 4 or Rayplex-Mn applied in the starter band on or under the seed with equal effectiveness. The amount absorbed was directly related to the Mn concentration in the band. MnSO 4 at 100 mg Mn/ft of row increased the Mn content of the tissue from 17 ppm to more than 100 ppm. MnEDTA at a rate to supply 10 to 25 mg Mn/ft of row in bands on or under the seed did not affect seedling growth and Mn uptake was less than from the same rate of MnSO 4 . Rates of 50 and 100 mg Mn/ft of row from MnEDTA in the starter band on or under the seed caused death or severe stunting of tomato seedlings because of toxicity. Band applications of Mn sources increased Mn composition of the tomato tissue relatively much more than did the broadcast application.
