Sp291-E-Growing Sweet Corn In Home Gardens, The University Of Tennessee Agricultural Extension Service

Home Garden, Lawn, and Landscape

Corn is one of the most popular and diverse vegetables. Many types are grown, including field corn, ornamental corn, popcorn, sweet corn, several different supersweet corns and even broomcorn. Corn may be white, yellow, bicolor and many shades of red, blue or even black. Most home gardeners grow white, yellow or bicolor corn or supersweet corn, so this factsheet will be restricted to these.

The yield and quality of home-grown corn also vary more widely than the yield and quality of most other vegetables. The type of corn grown, cultural conditions of growth, harvest and post-harvest treatment all affect yield …

Economic Importance Of Managing Spatially Heterogeneous Weed Population, John L. Lindquist, J. Anita Dieleman, David A. Mortensen, Gregg A. Johnson, Dawn Y. Wyse-Pester

Department of Agronomy and Horticulture: Faculty Publications

Three methods of predicting the impact of weed interference on crop yield and expected economic return were compared to evaluate the economic importance of weed spatial heterogeneity. Density of three weed species was obtained using a grid sampling scheme in 11 corn and 11 soybean fields. Crop yield loss was predicted assuming densities were homogeneous, aggregated following a negative binomial with known population mean and k, or aggregated with weed densities spatially mapped. Predicted crop loss was lowest and expected returns highest when spatial location of weed density was utilized to decide whether control was justified. Location-specific weed management resulted …

Light-Test Weight Corn For Growing And Finishing Steers, B. A. Weichenthal, Ivan G. Rush, B. G. Van Pelt

Panhandle Research and Extension Center

Light-test weight corn (59.2 to 61.5 kg/hL; 46 to 48 lb/bu) was compared to normal corn (72 kg/hL; 56 lb/bu) in growing and finishing diets for largeframe crossbred steer calves in 2 consecutive yr. The source of the calves was the same each year as was the diet composition. Growing diet dry matter included 32.9% corn silage, 22.3% alfalfa haylage, 37% dry rolled corn, and 7.8% protein supplement. Finishing diet dry matter included 9.2% corn silage, 86.2% dry rolled corn, and 4.6% protein supplement. Rumensin was included in both diets and steers were implanted with Synovex Sâ at the start …

Ec98-893 Corn Basis Patterns From Selected Sites In Nebraska

University of Nebraska-Lincoln Extension: Historical Materials

The following publication contains corn basis patterns for several towns in Nebraska. The basic price information was collected through surveys, newspaper, elelctronic media, etc. The listing includes towns that are representative of different geographic locations in Nebraska. The amount of data varies among locations. This publicaiton will be updated each year by adding a year's data to each location which will allow the user to observe changes in the basis patterns over time.

G98-1359 Western Bean Cutworm In Corn And Dry Beans (Revised April 2004), Ronald C. Seymour, Gary L. Hein, Robert J. Wright, John B. Campbell

University of Nebraska-Lincoln Extension: Historical Materials

Western bean cutworm (WBC) can be a severe pest in corn and dry beans. Larval feeding damages both crops through reduced yield and quality. In corn, direct feeding losses may be compounded by fungal and mold infections associated with larval waste products. In beans, damaged or 'worm-chewed' beans are a significant quality factor for both processed and dry bagged beans. Western bean cutworm infestations occur every year in western Nebraska. In some years, this pest is found in high numbers throughout the state.

This NebGuide addresses the life cycle, scouting and treatment of the western bean cutworm in corn and …

G98-1372 Management Recommendations For Blocked-End Furrow Irrigation, Dean E. Eisenhauer, Brian L. Benham

University of Nebraska-Lincoln Extension: Historical Materials

Proper blocked-end furrow irrigation management practices can minimize water application, irrigation costs and the leaching of agri-chemicals below the root zone.

The goal of every irrigator should be to apply the right amount of water uniformly to meet crop needs. To do this, irrigators need to know how much water is applied and where it goes. In other words, they need to know how uniformly the irrigation water infiltrates into the soil profile. Achieving a uniform water application is not easy when using furrow irrigation. However, with a better understanding of how irrigation system management affects water distribution and a …

Ec98-278 Grazing Crop Residues, Richard J. Rasby, Roger Selley, Terry Klopfenstein

University of Nebraska-Lincoln Extension: Historical Materials

Nebraska has an abundance of crop residue available for late fall and winter grazing. However, several factors prevent the grazing of many fields, including the location of fields in relation to the cattle, the lack of shelter or appropriate fencing and water availability. Despite these limitations, residue grazing is an important resource to many cattle operations, primarily as either a winter feed resource for maintaining the breeding herd or putting weight on cull cows. Calves weaned in the fall can also be wintered on cornstalks if appropriate supplementation is used.
