Growth Analysis Based On Degree Days, M. P. Russelle, Wallace Wilhelm, R. A. Olson, James F. Power

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Comparisons of growth analysis functions within and among experiments are often confounded by sources of variation other than those imposed by treatment. we suggest use of a temperature index, such as modified growing degree days, as the divisor in growth functions to facilitate treatment comparisons within certain experiments and to reduce the effects of differing temperature regimes among experiments on these comparisons. Three experiments were identified to provide data to analyze this new approach. Mean absolute growth rate (GR) and mean relative growth rate (RGR) were compared in two experiments with maize (Zea mays L.) conducted in eastern Nebraska. …

G84-696 Small Grains For Silage Or Hay, Paul Q. Guyer, Terry L. Mader

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses the advantages and disadvantages of using small grains for silage or hay, including handling, storage, feeding, animal performance, and nitrate toxicity potential.

Small grain crops are potentially important sources of high quality forage. Harvesting small grains for hay or silage rather than as grain may mean increased dollar returns per acre. Small grain silage or hay represents more total nutrient production per acre than harvest as grain and, when fed to ruminants, results in increased animal production.

Barley Production And Soil Acidity, P J. Dolling, W. M. Porter

Journal of the Department of Agriculture, Western Australia, Series 4

One of the causes of reduced plant yields on acid soils is aluminium toxicity. because barley is extremely sensitive to this mineral, a project started last year to examine the influence of soil acidity on barley production in the main barley growing areas of Western Australia.

This article discusses some of the background information on the project and its aims.
