Within-row spacing effect on individual corn plant yield
… research has shown that modest non-uniformity of corn plant spacing has small, negative effects on grain yield. The extent to which this influence of distance to adjoining plants is due to compensatory yield adjustments is not known. In 2011 and 2012, high density stands in 76 cm rows were hand …

From field to rumen: foliar fungicide application on corn and its effects on the corn plant, corn silage, and Holstein cow performance
… large crop yields. The interaction of fungi and corn plants in the field threaten yields, decreasing the efficiency of food production and the nutritive quality of feedstuffs for ruminants. Fungicides can assist corn plants in protection from fungal infection by limiting yield losses and …

Machine Vision Systems for Real-Time Plant Variability Sensing and in-Field Application
In-field variations associated with corn plant spacing, growth stage, and population can lead to a significant yield differences. Since the ability to reduce these variations is directly related to the planter performance, a machine vision-based emerged corn plant sensing system (ECS) was developed …

Quantitative Determination of the Elements in the Nodes and Internodes of Normal and Abnormal Corn Plants
During the last decade the annual loss due to corn rot diseases has been so great that much attention has been given this problem. These diseases, according to several authorities are caused by certain fungi and bacteria which live parasitically upon the corn plant and are known as root, stalk and …

Use of herbicides, tillage, and grazing cattle for establishment of corn in rotation with alfalfa and rye
… to determine alfalfa (Medicago sativa) survival, corn (Zea mays) plant populations and corn growth in an alfalfa-corn rotation. Alfalfa was overseeded with rye (Secale cereale) in autumn prior to planting corn in spring of each year. Treatments were 1) non-grazed control with standard chemical …

Enhancing the feeding value of corn crop residues to improve beef cattle production
Corn has been used in cattle diets for more the 50 years in the United States. However, since 2005 when the “Ethanol Era” started, the demand for corn to be converted in to ethanol has been increasing. The increased demand for corn to be converted into ethanol, led to increased corn prices. When …

Above and below ground phenotyping methods for corn
… However, many other physical traits such as plant height, leaflet count, color, germination rate, and biomass are indicators of the plants’ overall health and future yields. This research provided a means in which an operator can measure an individual trait of a corn plant, and predict yield. …

FATE, TRANSPORT, AND MIXTURE TOXICITY OF TRANSGENIC BACILLUS THURINGIENSIS CORN (ZEA MAYS) AND ASSOCIATED INSECTICIDES
Corn is a dominating feature in the landscape of the Midwestern United States. Associated with this crop are a plethora of products from fertilizers to pesticides that help farmers maximize grain yield while minimizing costs. A widely accepted form of protection from major pests in the United …

Analysis of management factor contributions to high-yielding corn production systems
… and cumulative contribution to a high-yield corn production system. The five management factors (non-nitrogen (N) fertility, N fertility, hybrid trait, plant population, and fungicide application) were evaluated by establishing 2 levels (traditional and advanced) of each factor. Twelve total …

Factors affecting the nutritional composition and digestibility of corn for silage: Cover crops and cell wall composition
Corn silage is one of the major components in dairy cattle rations in the United States. Many factors affect the nutritional composition of corn for silage, such as cropping system, including cover crops, and the composition of the corn plant cell wall. The objectives of the first study were to …

Yield and water use efficiency of different plant populations of dryland corn and sorghum
… The objective was to determine the effect of plant population on yield, water use, and water use efficiency, of one cultivar of corn (<i>Zea mays</i> L.) and two cultivars of sorghum (<i>Sorghum bicolor </i>(L.) Moench). Plant population treatments for corn were 37, 49, and 62 thousand plants …

Effects of Corn (Zea mays L.) Stover Removal and Leaching on Soil Test and Whole Plant K Levels in Corn and K Fertilization/High-Input Treatments on Soybean Using Site-Specific Management to Increase Soybean (Glycine max) Production in South Dakota
<p>Potassium is important for crop production. Corn stover removal has the potential to reduce exchangeable and soluble soil potassium (K+) needed for optimal plant growth in addition to grain yield. An experiment was conducted in Aurora, SD, USA, to observe the effects of corn stover removal on …

Role of the Leucine-responsive Regulatory Protein during growth of the bacterial corn pathogen Pantoea stewartii subspecies stewartii in the xylem environment
In the United States corn is one of the leading agricultural products and one of the top exports. The majority of U.S corn is grown in the Midwestern region of the U.S. known as the Corn Belt where the bacterial disease Stewart's Wilt reduces crop yield. Pantoea stewartii subsp. stewartii (Pss) is …

In planta studies of the corn pathogen Pantoea stewartii subsp. stewartii and applications of a corn-based industrial byproduct
Corn is a valuable agricultural commodity in the United States and in the world. The causal agent of Stewart's wilt disease in corn, Pantoea stewartii subsp. stewartii, is a bacterial phytopathogen that is vectored into the plant by the corn flea beetle, Chaetocnema pulicaria. After entering the …
