Add AMALGEROL drops for more hops: increased yield [Rocov]

This trial was conducted in Ročov, Czech Republic, in the middle of the hops growing region Žatec. In 2009, at a time when plant nutrition via leaves was only at the beginning, we tested the effect of AMALGEROL in combination with a liquid NP 10-34 fertilizer and Zinc sulfate on hops yield and compared it to the regional average (standard crop protection and fertilization). 

AMALGEROL was applied once (2,5 l/ha), NP 10-34 was applied twice (2 x 2,5 l/ha) and zinc sulfate was applied 3 times (2 kg per hectare and application).
