Corn silage serves as a high-energy forage for dairy cows. This is most important for high-producing herds and on farms experiencing problems with making or buying highquality hay crop forage. Corn silage, with its relatively highenergy content, is also well adapted for use in low-cost rations for fattening cattle. Corn silage requires less labor per ton to produce than many other forage crops....

Corn (Zea mays L.) that has been genetically engineered to produce the Cry1Ab protein (Bt corn) is resistant to lepidopteran pests. Bt corn is widely planted in the midwestern United States, often adjacent to headwater streams. We show that corn byproducts, such as pollen and detritus, enter headwater streams and are subject to storage, consumption, and transport to downstream water bodies. Lab...

to study the root allelopathic effects of cool season crops on germination and early growth of three crops (sorghum, corn, and soybean), an experiment was conducted in seed research laboratory and greenhouse of college of agriculture, university of tehran. the experiment consisted of four cool season crops (wheat, barley, rye and pea) and control as the main plots, three spring-crops (corn, soy...

Abstraet-When ethanol fuel is produced from lignocellulosic materials such as wood, herbaceous plants, and agricultural and forestry wastes, its use as a transportation fuel reduces dependence on imported petroleum, decreases the balance of trade deficit, improves urban air quality, contributes no net carbon dioxide to the atmosphere, and provides new markets for depressed farm economies. The s...

Wildlife damage to crops is a widespread concern among agricultural producers and wildlife professionals. In the United States, raccoon (Procyon lotor) damage to field corn (Zea maize) has become a serious concern, as raccoon depredation to corn has increased significantly in recent years. However, little information is available to suggest the underlying factors responsible for recent increase...

ABSTRACT Eight different 3-year cropping systems, consisting of soybean-canola, soybean-barley, sweet corn-canola, sweet corn-soybean, green bean-sweet corn, canola-sweet corn, barley-clover, and continuous potato (non-rotation control) followed by potato as the third crop in all systems, were established in replicated field plots with two rotation entry points in Presque Isle, ME, in 1998. Cro...

Agricultural production in the Midwestern US is highly concentrated with 85% percent of cropland acreage planted to only corn and soybeans (NASS, 2006). Crop specialization has improved the productivity and market efficiency of grain based commodity crops, but maintaining profitability has become increasingly difficult as input prices continue to rise while grain prices fluctuate substantially ...

Stoichiometric and kinetic values of phenolics against DPPH (2,2-diphenyl-1-picrylhydrazyl) were determined for Andean purple corn (Zea mays L.) and red sweetpotato (Ipomoea batatas). Both crops had higher antioxidant capacity and antiradical kinetics than blueberries and higher or similar anthocyanin and phenolic contents. The second-order rate constant (k(2)) was 1.56, 1.12, 0.57, and 0.26 (m...

Storage sheds like these Cameroonian corn cribs leave crops vulnerable to Aspergillus contamination. But contamination isn't always as obvious as it is on this ear of corn, and aflatoxin exposure can go undetected until health effects occur. Aid and development agencies are helping farmers learn how to spot and prevent Aspergillus.
