All treatments significantly increased grain yield above the control. Vitazyme produced a 126% yield improvement, while the highest yield was generated by Vitazyme + 200 kg/ka NPK (+316%). This was 17.0 grams/m2
higher than the 200 kg/ha NPK value. The difference was even greater for the 100 kg/ha NPK rate, where Vitazyme plus the fertilizer increased yield by 308%, but without Vitazyme the yield increased 207%. These data
show a marked improvement of fertilizer efficiency with Vitazyme at the lower NPK rate, and also an improvement at the high NPK rate.
