The below linked pdf contains the fruit maturity data to date. Please note that the August 28 sampling consists only of measurements from fruit grown at the Alson H. Smith, Jr. AREC. Due to differences in location, soils, rootstocks, strains, etc. these data may not represent the fruit maturity in your own orchards.
Please see my previous post about maturity indices for more information about the different maturity measurements. And, my post on the annual end of August maturity testing to see how this year compares to previous years.
