Soybean Yields

Profitable Soybean Management, 2005

Combinations of planting date, row spacing, plant population, and variety maturity determine the potential amount of solar energy a crop can convert to chemical energy as grain, and this is the essence of crop management. We must use variety selection, pesticides, tillage, and other cultural practices to eliminate or reduce the stresses that reduce yield. The components of each production system must be compatible with one another and the environment. They must also be economical, flexible and easily applied. Historically, producers have used the soybean canopy to shade out weeds starting about six weeks after planting when herbicides loose their effectiveness. Seeding rates were and are still higher than needed for maximum yield and in many cases are decreasing profit. Dr. Beuerlein’s presentation will include a brief discussion of the basic physiological principals of crop production and how they are used to maximize yield. Also included is a discussion of economic principals used to control production costs and increase profits. The balance of the presentation will be devoted to the profitable use of cultural practices and inputs used to produce soybeans.
