Nebraska soybean and corn yields steadily increased from 1971 to 2016, in both irrigated and rainfed production fields. Charts based on USDA National Agricultural Statistics Service numbers track these changes.
With nighttime lows predicted to drop several nights this week, growers are advised to cautiously assess the potential for germination problems due to imbibitional chilling before planting. Agronomists advise checking soil temperatures in each field the day of planting as well as forecast temperatures for 24 hours (soybeans) or 48 hours (corn) after planting.
Numerous soybean seeding rate studies have indicated that a final plant population of about 80,000 to 120,000 plants per acre is likely sufficient for ensuring an economic return, with the latter being based on weighing the slightly higher yield potential with higher final pl
Weather during the growing season (sunlight, temperature, and rainfall) will ultimately determine the soybean yield potential in a given year. While it is difficult to predict the weather ahead, you have an opportunity to manage your planting date to increase the odds of achieving a higher yield in 2016.
