Stubble Losses Of Kentucky Soybeans, Larry J. Grabau, Todd W. Pfeiffer

Agronomy Notes

Double crop soybeans in Kentucky tend to be shorter than plants from full season plantings. Since lowest pod height is related to plant height, double crop soybeans may be subject to greater harvest losses due to pods remaining below the level at which the combine header is operated. While it would be possible to lower the header closer to the soil to pick up some of those pods, that would slow down harvest and increase the risk of picking up stones and other trash. Although the actual cutting heights used in Kentucky are not known, some producers use combines with …

Studies On I) Dry Matter And Nitrogen Disappearance Of Six Soybean Protein Products In Situ And Ii) Contamination Of In Situ Dry Matter And Nitrogen Disappearance With Acid Detergent Fiber, James Coomer

Masters Theses & Specialist Projects

In experiment I), dry matter disappearance (DMD) and nitrogen disappearance (ND) of raw soybeans (RAW), solvent extracted soybean meal (SBM), heat treated whole soybeans (HT), mechanically extracted soybean meal (MEX), dry extruded soybeans (DEX), and wet extruded soybeans (TEX), were studied in situ for times of 3, 6, 12 and 24 h of rumen exposure. Five gram, air dry, samples were suspended in the rumen of a lactating Holstein cow fed a total mixed ration twice daily. The percent DMD for 24 h was as follows: RAW-85.9; SBM-56.6; HT-39.0; MEX-40.2; DEX-28.0; TEX-43.3. The greatest DMD was observed with RAW and …

Some Effects Of Shifting To Conservation Tillage Systems For Intensive Production Of Corn And Soybean, Kenneth L. Wells, H. C. Vaught, David Heisterburg

Agronomy Notes

About three-fourths of Kentucky's cropland base occurs on sloping land with some degree of erosion hazard. During the past decade, production of soybeans and corn increased rapidly in Kentucky, particularly on sloping land. This resulted in severe erosion on many farms, particularly in the "intensive grain producing counties. Much of this field erosion could be greatly reduced by developing a system for each field that would incorporate use of such agronomic practices as sod waterways, no-till planting, contour plowing, minimum tillage, strip cropping, double-cropping, winter cover crops, crop residue management and rotations. It is believed that the current acreage of …

Frost Damaged, Immature Soybeans For Ruminant Diets, J.A. Loesche, R. H. Pritchard, J. M. Reecy

South Dakota Beef Report, 1989

The potential for including freeze damaged, immature soybeans (FDIS) into corn based diets for ruminant animals was evaluated in a series of experiments. No differences in feeding value were evident for FDlS and normal soybeans except due to oil content. Oil content of soybeans depressed dry matter and particularly fiber digestion of corn silage fed to lambs (Pe.05). Nitrogen digestion and retention were also reduced (Pe.10) by feeding raw soybeans. The effect on N utilization appeared to be due to trypsin inhibitor activity, since this did not occur when soybean meal + oil supplements were fed. Nitrogen, dry matter and …

Will Liming Acid Soils Now Be Adequate For Spring Needs?, Kenneth L. Wells, J. L. Sims

Soil Science News and Views

Each spring many farmers are faced with seeding forages, corn, and soybeans, and transplanting tobacco into acid soils. The choices are either to go ahead with planting and do nothing, don't plant, or to try some liming practice and hope that it works. The results from planting without doing anything may be disastrous or result in limited crop performance. While not planting is a viable option for some producers, most cannot afford this choice. The question most often faced is, "Will liming now do any good for this year's crop?"

G89-953 Soybean Chlorosis Management, Edwin J. Penas, Richard A. Wiese

University of Nebraska-Lincoln Extension: Historical Materials

Four management ideas that make it possible to grow soybeans on alkaline soils are covered here.

Chlorosis (yellowing) in soybeans can be a problem wherever soybeans are grown on alkaline soils in Nebraska. Serious chlorosis is likely to occur when the pH of these alkaline soils is 7.5 or higher. Soybean chlorosis problems occur in the Platte and Elkhorn River Valleys and, to a lesser extent, in the Republican and Loup River Valleys, and on high lime soils in central and western Nebraska. Not all high pH soils cause chlorosis of soybeans even though they are alkaline.
