Comparison Of Laboratory Methods And An In Situ Method For Estimating Nitrogen Mineralization In An Irrigated Silt-Loam Soil, Brian J. Wienhold
Comparison Of Laboratory Methods And An In Situ Method For Estimating Nitrogen Mineralization In An Irrigated Silt-Loam Soil, Brian J. Wienhold
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Nitrogen (N) mineralization makes a considerable contribution to crop-available N and is difficult to estimate. Reliable methods for measuring N mineralization are needed to produce data sets for developing N-mineralization models, as a component in fertilizer recommendation algorithms, and to assess the effect of management practices on N mineralization. Numerous methods are available for estimating N mineralization. Laboratory methods are relatively easy but may not reflect conditions in the field, and field methods are usually labor-intensive. A study was conducted to compare N-mineralization estimates using anaerobic and aerobic laboratory methods and an in situ field method for the 0- to …
W166 Accent™ Herbicide For Weed Control In Sweet Corn, The University Of Tennessee Agricultural Extension Service
W166 Accent™ Herbicide For Weed Control In Sweet Corn, The University Of Tennessee Agricultural Extension Service
Field & Commercial Crops
The convenient control of perennial and annual grass weeds in fresh market sweet corn has been difficult for a number of years due to the lack of available postemergence herbicide options. Accent™ herbicide has been labeled for use in processing sweet corn for a number of years but was not cleared for fresh market use until fall 2006. One concern with Accent™ use is that a small number of sweet corn hybrids could have low tolerance to nicosulfuron, the active ingredient (Figure 1). Additionally, delayed applications of the herbicide or applications with improperly calibrated spray equipment could result in ear …
W164 Replanting Corn - In A Failed Roundup™ Ready Corn Stand, The University Of Tennessee Agricultural Extension Service
W164 Replanting Corn - In A Failed Roundup™ Ready Corn Stand, The University Of Tennessee Agricultural Extension Service
Field & Commercial Crops
In spring 2007, a widespread freeze occurred that led to the replanting of about 200,000 acres of corn in Tennessee. In most years, replant decisions have to be made on a limited number of acres when corn fields have insufficient stands for optimum yields. Producers are then forced to make a number of decisions quickly, because planting delays, particularly into mid-May, can greatly affect yield potential of the replanted crop.

Corn-based ethanol production is exponentially growing in the U.S. As the use of ethanol as a fuel source increases, so does the need to find valuable uses for coproducts of the production process, such as distillers dried grains with solubles (DDGS). DDGS is a good source of nutrients, energy, and protein. Currently DDGS is sold by ethanol processors as livestock feed, thereby increasing profit for the production plants. As the industry continues to grow, there will be a growing need to find additional uses for DDGS. Physical and chemical properties of coproduct streams are becoming increasingly investigated, as these characteristics …

The U.S. feed grain sector, largest of the major U.S. field crops, faces unprecedented demand conditions. The size and speed of the expanding use of corn by the ethanol industry is raising widespread issues throughout the U.S. agricultural sector. Debate is ongoing over the use of grain for fuel instead of for food or feed and the adequacy of future grain supplies. Increased productivity (yield) and additional area from land planted to competing crops, land enrolled in conservation programs, or idled land is expected to provide an increased supply of feed grains. In 2003, U.S. feed grain farms had an …

Compost And Manure Effects On Fertilized Corn Silage Yield And Nitrogen Uptake Under Irrigation, Gary A. Lehrsch, D. C. Kincaid
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Dairy manure increases the yields of dry bean (Phaseolus vulgaris L.) and spring wheat (Triticum aestivum L.) from eroded, furrow-irrigated soils and may increase corn (Zea mays L.) silage yield from steeper eroded areas under sprinkler irrigation. In a 2-year field study in southern Idaho on Portneuf silt loam (coarse silty, mixed, superactive, mesic Durinodic Xeric Haplocalcid), the effects of a one-time, fall application of 29 or 72 Mg ha-1 of dry manure or 22 or 47 Mg ha-1 of dry compost on subsequent silage yield and nitrogen (N) uptake from previously eroded, sprinkler-irrigated hill …
Use Of Exogenous Fibrolytic Enzymes To Enhance In Vitro Fermentation Of Alfalfa Hay And Corn Silage, Jong-Su Eun, K. A. Beauchemin, H. Schulze
Use Of Exogenous Fibrolytic Enzymes To Enhance In Vitro Fermentation Of Alfalfa Hay And Corn Silage, Jong-Su Eun, K. A. Beauchemin, H. Schulze
Animal, Dairy, and Veterinary Science Faculty Publications
Two in vitro experiments were performed to identify promising exogenous fibrolytic enzyme products (EFE) and optimum dose rates (DR) for improving the degradation of alfalfa hay and corn silage. The relationship between enzymatic activity and fermentation responses was examined to identify optimum formulations. In experiment 1, 5 EFE containing mainly endoglucanase and xylanase activities, with different ratios between the 2 activities, were assessed at a DR of 0.7, 1.4, and 2.1 mg/g of DM forage. Milled alfalfa hay or corn silage was incubated in an in vitro batch culture with buffer, ruminal fluid, and EFE. Gas production (GP) was measured …

Enhancing In Vitro Degradation Of Alfalfa Hay And Corn Silage Using Feed Enzymes, Jong-Su Eun, K. A. Beauchemin
Animal, Dairy, and Veterinary Science Faculty Publications
A series of in vitro fermentation experiments was performed to assess the effects of 4 feed enzyme products (FE) that varied in enzymatic activities on the degradation of alfalfa hay and corn silage. The FE contained a range of endoglucanase, exoglucanase, xylanase, and protease activities, and a range of dose rates (DR) was used. The objective of the study was to identify effective formulations and optimum DR, and to establish if combining FE would further improve fiber degradation. For alfalfa hay, quadratic increases in gas production and degradation of dry matter (DM) and fiber were observed for all FE, with …

Human–Wildlife Interactions
Management programs aimed at reducing wildlife damage to row crops rely on information concerning the spatial nature of wildlife damage at local and landscape scales. In this study we explored spatial patterns of wildlife damage within individual corn and soybean fields by describing relationships between specific locations where wildlife damage was recorded and distances from such locations to various habitat types that presumably influenced animal abundance and movements in our study area. Using stratified random sampling, we conducted depredation surveys of 100 corn fields and 60 soybean fields from May through October both in 2003 and 2004 and recorded the …
Drivers Of Liking And Effects Of Corn Hybrics On Quality Of Corn Tortilla, Jose Andres Herrera Corredor
Drivers Of Liking And Effects Of Corn Hybrics On Quality Of Corn Tortilla, Jose Andres Herrera Corredor
LSU Doctoral Dissertations
Corn tortilla, an ancient staple food of Mexico and Central America, is still the base food in those countries and has also become more popular in other countries with high Hispanic population. However, mechanization of corn tortilla production has modified the original sensory attributes to new standards that meet manufacturer’s requirements. The first part of this study attempted to determine the sensory attributes that drive consumer’s decision on the acceptability and purchase intent of the corn tortilla available in the Mexican market. The findings may help manufacturers to improve the processing of tortilla and develop products with ethnic authenticity. Overall …
