Grapevine yield increase with AMALGEROL and AMALGEROL ESSENCE

This trial is a sequel of the trial T0136 ("Stronger and more vital vines withstood unusual hot and dry weather and produced more grapes of better quality with AMALGEROL").

In an organic-certified established vineyard in Austria, the two products AMALGEROL and AMALGEROL ESSENCE (in an early version of development) were used in the same concentrations in eight foliar applications on 14-years-old Zweigelt vines.

Both products increased the yield considerably.
