High Management Soybean System
• While soybean maximum yield potential is genetically determined, actual yield potential depends on environmental conditions and management practices. • Growers are considering additional inputs and management practices to more fully exploit the genetic potential of soybean. • Studies have shown that stress mitigation practices such as maximizing nutrient availability and reducing competition from weed, insect, and disease pressure can help increase soybean yield potential. • Seed treatments, rhizobium inoculant, foliar fungicide, foliar insecticide, and foliar-applied nitrogen are several inputs being examined for their effect on soybean yield potential.

High Management Soybean System
• Evaluate the yield response to a stair-step high management approach beginning with untreated seed and adding treatments for each plot to determine which treatment gives the greatest yield response.

High Management Soybean System
• Of the five management components studied, foliar applied fungicide at R3 showed the greatest response for the 2014 growing season. • In 2014, cool wet conditions led to a high incidence of soybean diseases. The response to fungicides from year to year can be very inconsistent. • Good agronomic practices such as row spacing, planting date, and population can help increase soybean yield. • Further studies will be conducted to examine high management soybean systems and their ability to maximize yield potential.

Soybean Population by Stress Mitigation 2013 Demonstration Report Monsanto Learning Center at Monmouth, IL ISA RESEARCH Advancing Agricultural Performance® and Environmental Stewardship Funded in part by the soybean checkoff
Soybean Population by Stress Mitigation
Trial conducted at Monsanto Learning Center at Monmouth, IL was designed to investigate: • How different treatments for minimizing stress on soybean affected their yield potential at different plant populations • The most profitable plant populations for the given trial location – Different populations may be more beneficial in other areas
ISA RESEARCH Advancing Agricultural Performance® and Environmental Stewardship Funded in part by the soybean checkoff
Soybean Population by Stress Mitigation
• Genuity® Roundup Ready 2 Yield® soybean • Planted June 7, 2013 • Conventional tillage: Fall chisel plow followed by Spring soil finisher to establish seed bed • Pre-emergent herbicide applied June 7, 2013 • Harvested October 11, 2013

Soybean Population by Stress Mitigation
• Plant populations: 75K, 100K, 130K, 170K, and 200K seeds per acre in 30-inch rows • Each population had treatments of: – – – – – –
Untreated control Foliar fungicide at R3 Foliar insecticide at R3 Foliar fungicide + insecticide at R3 Foliar fungicide + insecticide at R3 and R5 Sugar at R1
• R1 applications were applied July 23, 2013 • R3 applications were applied August 1, 2013 • R5 applications were applied August 19, 2013
ISA RESEARCH Advancing Agricultural Performance® and Environmental Stewardship Funded in part by the soybean checkoff
Soybean Population by Stress Mitigation
• There was an upward trend in yield with increasing plant populations. • Of the five stress mitigation treatments, foliar fungicide plus foliar insecticide applied at R3 and R5 showed the highest yield. – The 2013 results do not agree with long term data as there has not typically been a yield response with foliar fungicide and insecticide applications at R3 and R5 at this location.
• The 130K population provided the most profitable scenario in this trial (considering gross income and seed cost). ISA RESEARCH Advancing Agricultural Performance® and Environmental Stewardship Funded in part by the soybean checkoff

Soybean Population by Stress Mitigation
• A greater response to stress mitigation was demonstrated at higher plant populations. – Higher plant populations create more stress on the plant, therefore reducing outside stress can result in increased yield.
• While increased yields were observed at higher planting populations, those increases did not result in optimum profitability. • Good agronomic practices such as proper planting date and population can help reduce environmental stresses. • Some of the treatments may not have caused a response due to the late planting date and drought. • The Monsanto Learning Center at Monmouth will continue to investigate the yield effects of stress mitigation in soybean.

Managing Soybeans for High Yield Potential Results and Discussion • Little to no yield response was seen in the individual fungicide and insecticide treatments • However, when fungicide and insecticide applications were combined, an increase of approximately 4 bushels was observed - This positive yield response was in spite of the fact that insect and disease pressures were observed to be lower than normal. - This could mean that responses to fungicide and insecticide applications would be even greater in a year with higher pressures.
ISA RESEARCH Advancing Agricultural Performance® and Environmental Stewardship Funded in part by the soybean checkoff
Managing Soybeans for High Yield Potential Results and Discussion • The addition of foliar applied sugar is a practice of interest to many area soybean farmers. - However, this treatment showed no benefit in this trial.
• The combination of inoculant, fungicide, and insecticide in this trial yielded 4.6 bu/a more than the untreated check and represented an input cost of approximately $26 per acre (excluding application cost). - Therefore, break-even price for soybeans would be approximately $5.65 per bushel. At the time of harvest, the cash soybean market was approximately $10 per bushel, resulting in a $20 per acre profit for the combination of inoculant, fungicide, and insecticide.
