A field study was conducted to compare the effectiveness of foliar feeding different boron fertilizer materials currently available to the Georgia cotton farmer. Five different boron fertilizers were foliar applied to field plots in 1999 and 2000. All treatments were appplied at recommeded rates and then plant tissue samples taken 10 days after application. Yields were also measured on all plots. In both years, a granular boric acid material was the most effective in raising the concentration of boron in the cotton leaf tissue. A granular sodium borate and liquid boric acid were both slightly less effective but were well above the untreated check. A sodium borate liquid, “organically complexed” and containing nitrogen was not different than the untreated check as far as raising leaf tissue boron. No yield response was measured for any treatment. This was due to more than sufficient boron concentrations in all treatment including the untreated check. Additionalk boron applied in either a preplant or sidedress fertilizer each year is thought to be the cause of this result.
