Results
General results
The results show that a single Multicote™ Agri application, at 70% level of nutrients, have a higher number of fruits and a higher average weight per fruit, for all the tested varieties.
A single application of a Multicote™ Agri blend was able to produce the same yield while using 30% less nutrients by following the real crop demand and supplying the needed nutrients throughout the growing season.
