Common Pokeweed Management In Corn And Soybeans With A Conservation Tillage Cultivator And Herbicides, Jonathan D. Green, William W. Witt

Agronomy Notes

Common pokeweed (Phytolacca americana L.) is a warm-season perennial that grows well in nondisturbed areas such as fence rows and woodland borders. In recent years it has begun spreading to com and soybean fields where no-tillage practices are used. The deep taproot that is characteristic of common pokeweed, makes this weed difficult to manage, particularly in no-till plantings. The green leaves, fleshy stems, and purple berries of common pokeweed can inhibit the harvesting process and lead to discounts at the elevator for high moisture and stained seed.

The equipment industry has developed cultivators with large sweeps capable of operating …

G99-1395 Soybean Seeding Rates, Roger Wesley Elmore, James E. Specht

University of Nebraska-Lincoln Extension: Historical Materials

Recommended soybean seeding rates, stand assessment and replanting rates based on Nebraska field research are addressed in this NebGuide. The soybean stand looked horrible late that May. The field had a good seed bed at planting, but rain after planting crusted the soil over the seed furrows. Rain was in the short-term forecast. All other row crops were planted and looked fine, but this field concerned the producer.

Chlorophyll Meter Assessments Of Corn Response To Nitrogen Management Practices, M. M. Siambi, D. L. Karlen, R. M. Shibles

Journal of the Iowa Academy of Science: JIAS

Environmentally sound nitrogen (N) management is necessary to simultaneously achieve high crop yields and protect surface and groundwater quality. We evaluated a hand-held chlorophyll meter as a diagnostic tool for improving management for corn (Zea mays L.). Five N fertilizer rates (0, 67, 134, 201 and 280 kg N ha^-1) were evaluated in one study, and in a second study, the meter was used to evaluate the N status of corn plants grown under varying tillage (chisel plow vs no-till), crop rotation (continuous corn vs corn-soybean [Glycine max (L.) Merr.]), and N management treatments. Meter readings were …

G99-1385 Common Stalk Rot Diseases Of Corn, James Stack

University of Nebraska-Lincoln Extension: Historical Materials

Corn stalk rot diseases occur every year in every field to some extent. This NebGuide discusses the symptoms, impacts and management of these diseases.

Corn is grown throughout Nebraska on over 8 million acres of land; approximately 5 million acres are irrigated. Seed corn, field corn and specialty corns (e.g., high oil, high amylose and white corn) comprise the three main corn production systems. Field corn is grown on the most acreage. Whether grown in an irrigated or dryland production system, all corn hybrids are susceptible to a variety of stalk rot diseases. These diseases occur every year in every …
