🌾 +17.8% Higher Wheat Yield Under Spring Drought
A field trial at the Maize Institute in Knezha, Bulgaria, evaluated AMALGEROL ESSENCE under severe spring drought.
After favourable autumn sowing conditions and a warm winter, the crop received just 7.6 l/m² of rainfall in February, followed by below-average precipitation throughout March and April - ideal conditions to demonstrate the benefits of biostimulants under drought stress.
✔️ +17.8% higher grain yield compared to the untreated control
✔️ Prolonged "green effect" for improved grain filling
✔️ Better grain quality with higher thousand-grain weight and hectolitre weight
✔️ Stronger performance despite reduced nitrogen fertilisation
The trial clearly demonstrated the benefits of AMALGEROL ESSENCE under drought conditions. Applied twice at 2 l/ha, the treated wheat achieved a grain yield of 728 kg/ha compared to 618 kg/ha in the untreated control, while receiving less nitrogen fertiliser.
