INSIGHTS
On average, YieldON™ increased corn yield by 4 Bu/A and soybean yield by 1.5 Bu/A.
Depending on the location, yield increases up to 11 Bu/A in corn and 6.2 Bu/A in soybeans were observed.
YieldON can improve late-season nutrient and sugar transport, cell division, kernel/seed and pod development and retention.
YieldON
YieldON, a biostumulant engineered by Syngenta Biologicals, is designed to increase row crop productivity. It was developed using innovative technologies such as genomics, phenomics, and next-generation sequencing, allowing researchers to detect expressed genes related to increasing plant productivity. YieldON contains a selection of extracts from three families of plants and seaweeds and is enriched with three micronutrients: manganese, zinc, and molybdenum. This formula aids in the efficiency of the plant’s physiological processes responsible for seed development and resulting yield. YieldON has three distinct modes of actions:
- Better transport of sugars and nutrients
- Promotion of cell division – more and larger seeds
- Fatty acids biosynthesis and transport
YieldON up-regulates genes responsible for these mechanisms, increasing plant growth and development even during periods of crop stress.
Agronomy in Action Research Trials
The Agronomy in Action research team implemented trials in both corn and soybeans to evaluate the effect of foliar-applied YieldON.
Corn trials were conducted in 2022 and 2024 across the Midwest. YieldON (1.5 pt/acre) was applied in combination with the fungicide Miravis® Neo (13.7 oz/acre) and compared to an application of fungicide alone. Treatments were applied at the R1 (silking) growth stage utilizing a DJI Agras T20P spray drone with 5 gallons per acre water carrier volume.
Soybean trials were conducted in 2021 and 2024. In 2021, YieldON (1.5 pt/acre) was applied in combination with the fungicide Miravis Neo (13.7 oz/acre) and the insecticide Endigo® ZC (3.8 oz/acre) and compared to the same combination of fungicide and insecticide without YieldON. In 2024, YieldON was applied with only the fungicide and compared to the fungicide alone. Treatments were applied with a ground sprayer with 20 gallons/acre carrier volume at the R3 (beginning pod) growth stage.
Corn Yield Results
On average across all site years, applications of YieldON increased corn yield by 4 Bu/A (Graph 1). The largest yield response was observed at Sac City, IA, in 2022 where yield was increased by 11 Bu/A. YieldON tended to increase yield by ≥ 4 Bu/A at 6 of the 11 locations (Graph 1).
*yield response with YieldON was significant at α=0.10.

On average across all site years, applications of YieldON increased soybean yield by 1.5 Bu/A (Graph 2). Soybeans grown at two sites in 2024, Blue Earth, MN, and Grundy Center, IA, had a significant response to YieldON, yielding 6.2 and 4.4 Bu/A greater respectively. 80% of locations showed a positive yield response to YieldON while 6 out of 15 locations responded by ≥ 1.5 Bu/A (Graph 2).

YieldON added to a foliar application during the reproductive stages significantly increased yield in both corn and soybeans, on average. The three modes of action of this biostimulant makes it beneficial across a variety of environments. Utilizing YieldON in both corn and soybeans to improve crop can help boost yields.
