Over 250 trials on 120 different crops from over 90 countries.

Fill Max

Sunflower in dry and irrigated land

Cuenca, Spain

The application of FILL MAX in different varieties of sunflower both in dry and irrigated land has allowed to increase yield in the 3 trials carried out. The oil economic yield in the dry land field has been lower in the FILL MAX variant, while in the irrigated fields it has been higher. The oil production has been greater in the variants treated with FILL MAX.


Increased oil yield, kg/ha

Greater gross and net benefits
