The test trials reported in this publication were conducted by the Plant Science Department Crop Performance Testing Program, Agricultural Experiment Station.

Stability Of Cereal Crop Yields' Performance: An Econometric Analysis For India And Andhra Pradesh., A. Ganesh Kumar Dr.

Doctoral Theses

Agriculture is an importannt sector of the economy in many developing countries. Of late, in many countries, this sector Is believed to be suffering from unstable performance, especially where the modern (Green Revolutlon) technology has been widely adopted. The issue of stability of agricul tura! performance is one of international concern. This thesis is about the performance of cereal crop yiel ds in India.Importance of Agriculture in the Indian Economy.Agriculture is an important sector Aooounting for more than 30% of the countrys national 1988-89, the performance of agriculture, both as nateriais for industrla! producelon ponsumption demand, determines of the Indian …

Control Of Rodents In No-Till Corn, Lloyd W. Murdock

Soil Science News and Views

The prairie vole is probably the primary rodent that reduces no-till crop plant stands in Kentucky. Because the vole requires a full canopy cover for protection from predators, established grass or legume sod fields and field borders (including wheat or rye stubble, set-aside and cover crop seedings) provide an ideal habitat.

An Estimate Of The Source And Uptake Of Nitrogen In Continuous No-Till Com Grain Production, Kenneth L. Wells

Soil Science News and Views

The U.S. Environmental Protection Agency (EPA) has established a maximum nitrate nitrogen (NO₃-N) content of 10 parts per million (ppm) for safe drinking water. Because of this, the effect of commercial nitrogen (N) fertilizers in agricultural production as a contributor of NO₃-N to surface and groundwater is now being widely examined. Since corn production in the US is the largest single source of fertilizer N use, averaging perhaps 100-150 lbs N/A on the 70-80 million acres of corn produced annually, an understanding of N utilization and losses in corn production is helpful in determining the role …

Using Poultry Manure From Layers As A Supplemental Nitrogen Source For Corn, Lloyd W. Murdock, R. Darrell Simpson, Tim Gray

Agronomy Notes

The objectives of this study were to try to find an effective inorganic nitrogen (N) fertilizer rate to apply to a corn crop when poultry manure has been used on the field and to see if an N soil test at sidedress time could help predict the amount of N needed.

Pirimiphos-Methyl Degradation And Insect Population Growth In Aerated And Unaerated Com Stored In Southeast Georgia: Small Bin Tests, Frank H. Arthur, James E. Throne

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

Lots of 229 kg untreated seed com and com treated with 8 ppm pirimiphosmethyl were stored in unaerated bins and bins modified with a fan blower to provide aeration. The corn was infested artificially with adults of the red flour beetle, Tribolium castaneum (Herbst); the maize weevil, Sitophilus zeamais Motschulsky; and eggs of the Indianmeal moth, Plodia interpunctella (Hiibner), to determine the effects of aeration on insect control in southeastern Georgia. Total temperature units in unaerated and aerated treated corn during the storage period of 15 October through 4 August were 5,729 and 5,196 degree-days, and moisture content was significantly …

G94-1205 Shattercane And Its Control, Fred Roeth, Alex Martin, Robert N. Klein

University of Nebraska-Lincoln Extension: Historical Materials

Shattercane infestations may destroy a crop if not properly controlled. This NebGuide describes the characteristics of shattercane and discusses non-chemical, preemergence, herbicide incorporation and postemergence control.

Shattercane (Sorghum bicolor L. Moench) is a forage-type sorghum also known as black amber, chicken-corn, and wild cane. Infestations are most prevalent in Nebraska river valleys and tributaries, but are found in upland areas also.

G94-1231 Harvesting Corn And Sorghum For Silage, Rick Grant, Rick Stock

University of Nebraska-Lincoln Extension: Historical Materials

This publication describes how to make high-quality corn and sorghum silage.

Quality Silage

Silage feeding quality is determined by 1) the nutrient content of the crop stored, 2) the stage of maturity and moisture content when harvested and 3) the effectiveness of silage preservation.

Rp94-217 No. 18 Use Of Crop Futures And Options By The Nontrader, George Flaskerud, Richard Shane

University of Nebraska-Lincoln Extension: Historical Materials

Crop producers make a number of decisions that are market related. They may be categorized as financial decisions, production decisions, or marketing decisions. All three decisions depend on what prices are likely to be at some specific time in the future.

The marketing decisions is complex. This research publication discusses the number of alternatives that are available even for the producer who does not directly buy or sell futures or options contracts.

Nf94-206 Common Ground: The Case Of Seasonally Inundated Cropland, William Miller

University of Nebraska-Lincoln Extension: Historical Materials

Increasing waterfowl migration habitat has been a goal of many groups and individuals for decades. Individuals have provided money for habitat by supporting private organizations such as Ducks Unlimited, and through the purchase of hunting licenses, duck stamps, and habitat stamps. All these activities have helped, but funds have been limited so it has not been possible to provide enough wetland space for the migrating waterfowl.

This NebFact discusses cost effective ways to provide more waterfowl migration habitat on seasonally inundated crops and a seasonal strategy that could provide habitat for geese and ducks during the spring and fall migration …

Estimated Nutrient Content And Uptake By Kentucky's Crops, Kenneth L. Wells, William O. Thom

Soil Science News and Views

A commonly asked question by crop producers is, "how many pounds of plant nutrients do my crops take up?" While the absolute answer to this varies by yield and soil fertility, useful estimates can be made from research data to enable a producer to have a "ballpark" value for nutrient up-take by some of the major crops of Kentucky. The following tables contain estimates of nitrogen (N), phosphorus (P),and potassium (K) contained in certain crops and the amount of N, phosphate (P₂O₅), and potash (K,O) taken up by tobacco, corn, soybeans, wheat, alfalfa hay, clover grass …

Net Energy Of Finishing Diets Containing Light Or Normal Test Weight Corn, C. P. Birkelo, R. H. Pritchard, M. Buhman, S. Grosch, C. Willms

South Dakota Beef Report, 1994

Net energy (NE) of diets containing 77.7% whole corn of either normal (53.8 Ib/bushel, NC) or light (40.8 Ib/bushel, LC) test weight was determined by total collection and indirect respiration calorimetry using six crossbred steers (avg wt 327 kg). Diet treatments were applied in a switchback design. The steers were initially adapted to ad libitum intake of either NC or LC diets for 32 days followed by 7 days total feces and urine collection. Gaseous exchange was subsequently measured for at least 48 hours. Intake was then reduced to an estimated 1.1 times maintenance for 6 days and collections were …
