4. Conclusion
Sanbio EPSOMIT has shown very positive effects on plants and production. A few weeks after the first application of Sanbio EPSOMIT we found good vegetation, growth and vigor of plants in plots treated by Sanbio EPSOMIT relative to the control plot. After a single application of 1 kg of Sanbio EPSOMIT in experimental lots we increased the production of Mâali +20.5 q/ha (+57,7%), Mahmoudi +3.5 q/ha (+20,0%) and Triticale +1.5 q/ha (+5,5%) compared to control lot. The return-of-investment (ROI) for Mâali is 1:4.5. The seed quality of all plots treated by Sanbio EPSOMIT is better than that of the control lot.
