Impact of Foliar-Applied Manganese on Photosynthesis in Pecan in New Mexico

July 2011 – Effect of Mn Metalosate® an amino acid chelated form of Mn applied at different concentrations on two varieties of pecans. Mn applications increased Mn leaf concentration in direct correlation with application rate. Average photosynthesis and stomatal conductance for both varieties in two year of observance where best in medium concentration of application.
