The production and acreage of corn in Iran and in Fars Province, in particular, are expanding at an increasing rate. The impacts of this event was studied by a risk programming model (MOTAD). The results indicated that the optimal cropping patterns with corn had less variance than the optimal patterns without corn in all income levels. The results also showed that with the introduction of corn ...

Materials and Methods The Neely-Kinyon Long-term Agroecological Research (LTAR) site was established in 1998 to study the long-term effects of organic production in Iowa. Treatments at the LTAR site, replicated four times in a completely randomized design, include the following rotations: conventional Corn-Soybean (C-S), organic Corn-Soybean-Oats/Alfalfa (C-SO/A), organic Corn-Soybean-Oats/Alfa...
Advanced Corn Silage Production 605. Circle all correct answers and Discuss. 1. With corn silage, high grain yield reduces fiber production per acre. a. True. b. Likely. c. Doubtful. d. False. e. Conditional. 2. Delaying harvest decreases digestibility of NDF from corn silage. a. True. b. Likely. c. Doubtful. d. False. e. Conditional. 3. More mature corn silage has less NDF only because it is d...
Renewable fuel production, particularly grain-based ethanol, is expanding rapidly in the USA. Although subsidized grain-based ethanol may provide a competitively priced transportation fuel, concerns exist about potential environmental impacts. This contribution focuses on potential water quality implications of expanded grain-based ethanol production and potential impacts of perennial-grass-bas...
Many herbaceous lignocelluloses suitable for ethanol production have high extractives contents, such as some straws and corn stover. The high extractives content might affect pretreatment or enzymatic hydrolysis. In this study, extractives were removed from corn stover, and then extractives-free corn stover and ordinary corn stover were respectively pretreated using a liquid hot water (LHW) met...
Corn silage represents a mixture of highly digestible, energy-dense grain and a poor quality forage (stover). The value of altering the grain to stover ratio through agronomic and harvesting strategies has been recognized for some time, however many of these practices have been applied to hybrids selected primarily for grain yield and adapted for harvest as silage. Although the feeding value of...
In the phytophagous corn earworm, Helicoverpa (Heliothis) zea, females delay their reproductive behaviors until they find a suitable host on which to deposit their eggs. Perception of volatile chemical signals from corn silk triggers the production of sex pheromone followed by its release, which leads to mating. Several natural corn silk volatiles, including the plant hormone ethylene, induced ...
Recombinant protein production in plants such as corn is a promising means to generate high product yields at low comparable production cost. The anti-EGFR monoclonal antibody C225, cetuximab, is a well-characterized receptor antagonist antibody recently approved for the treatment of refractory colorectal cancer. We initiated a study to test and compare the functional activity of glycosylated a...
Increased production of corn based ethanol and the resulting increase in availability of distillers dried grain with solubles (DDGS) has a number of implications for the U.S. livestock industry and for the production of traditional livestock feed crops. Some of those implications are examined here. First, and most importantly, the potential size of the domestic market for DDGS is evaluated in d...
