Sp291-E-Growing Sweet Corn In Home Gardens, The University Of Tennessee Agricultural Extension Service May 1998

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 …
