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.

Conclusions

Summary

 

The results of this study show that a single application of a Multicote™ Agri blend can supply the Apple trees yearly nutrients demand while reducing the Farmer's practice nutrients amount by 30% and increasing yield both in terms of the number and the size of the fruits
