G81-552 Effects Of Weather On Corn Planting And Seedling Establishment, Ralph E. Neild
G81-552 Effects Of Weather On Corn Planting And Seedling Establishment, Ralph E. Neild
University of Nebraska-Lincoln Extension: Historical Materials
Corn planting usually begins when the average daily temperature first rises 55°F and the soil becomes sufficiently warm enough to initiate germination and sustain seedling growth. This may be as early as the middle of March in central Texas 700 miles south of Nebraska or as late as the middle of May in central South Dakota. Corn may be planted as early as the first week of April in southeast Nebraska and continue into the first week of June. Most of the corn, however, is planted between May 4 and May 21.
Corn planted early when the temperature is cool …

Nebraskans are increasing their consumption of fresh vegetables — as appetizers, salads, side dishes, and snacks. Fresh vegetables are an integral part of a healthy, well-balanced diet. Although Nebraska's climate and soil are well-suited for many vegetables, most are supplied from out of the state, even during summer. Growing fresh vegetables can provide higher nutrition and flavor at less expense than buying fresh produce at the grocery store. A garden also can be a source of personal enjoyment and satisfaction.
This extension circular helps the gardener decide when, where, and how to plant and maintain a vegetable garden.

Physiological disorders are plant diseases caused by non-living agents. Other terms for this group of disorders are abiotic diseases or noninfectious diseases.
Physiological disorders are often confused with pathogen-caused diseases but they do not spread from plant to plant as do diseases caused by living organisms. Landscape plants are often exposed to toxic materials, mechanical damage, nutritional stress, homeowner neglect and other stress factors in the urban environment.
This 4-color extension publication highlights the following physiological disorders of landscape plants: sun scald, drought, lightning injury, winter injury, root girdling, iron chlorosis, salt injury, herbicide injury and air pollution.
