yield increase VS control
Whitewater, Wisconsin
yield increase VS control
Key Conclusions
- Foliar application of macro- and micronutrients, including Nova PULSE and Nova FINISH, boosts soybean yields, especially during the R1-R2 growth stage. This timing is also ideal for combining foliar nutrition with fungicides and insecticides.
- Highest yields were obtained with Nova PULSE alone or combined with Nova FINISH, offering a significant return on investment with an average yield increase of 520 kg/ha.
Objective
To evaluate the effect of single and sequential applications of Nova PULSE™, a water-soluble foliar fertilizer designed to improve soybean N fixation and yield. Additionally, Nova FINISH™, a water-soluble NPK fertilizer with a full complement of micronutrients was applied alone and in combination. with Nova PULSE at the flowering stages of soybean to demonstrate another foliar nutrition option for late-season nutritional management of soybean.
Trial Details
Treatments
The early vegetative stage (V4-V6) application of Nova PULSE (0-6-4 + 1Mg 1.3S 0.5Co 10Mo 6Zn) occurred on 2 July 2023.
The flowering stage (R1-R2) applications of Nova PULSE and Nova FINISH (8-12-40 + 2.5S 0.03B 0.05Cu 0.1Mn 0.02Mo 0.1Zn) occurred on 20 July 2023. Nova PULSE was applied at a rate of 420 g/ha at each application, and Nova FINISH was applied at 2.2 kg/ha.
Applications occurred in a water volume of 187 L/ha. Each treatment was replicated four times.

Results
- Compared to the untreated control, which received no foliar nutrition, all treatments increased yield.
- The yield response to Nova PULSE was greater when applied at the R1-R2 stages. A sequential application of Nova PULSE at V4-V6 followed by a second application at R1-R2 resulted in a larger yield response (480 kg/ha) relative to the control.
- The treatment with the V4-V6 application of Nova PULSE followed by a R1-R2 application of Nova FINISH resulted in the highest overall yield (5.42 MT/ha), or a response of 560 kg/ha (11% increase), compared to the control.
