C ORN silage is being utilized in increased quantities in beef cattle growing and fattening rations. The research data of Hammes et al. (1964), with various ratios of corn to corn silage in fattening rations, have demonstrated that higher levels of corn silage can be justified because gains between high grain and high silage rations are similar, whereas, use of higher silage rations permits the...

increasing the water use efficiency in crop production is an important issue today. an experiment was conducted in 2009 in order to evaluate the corn reaction to partial root zone drying at fars province. treatments consisted of four irrigation levels (control, alternative furrow irrigation during whole season, alternative furrow irrigation until flowering then full irrigation and full irrigati...

Some often cited reasons why both grain and forage prices are and will continue to be high include utilizing corn for ethanol production and the pressure corn grain prices placed on shifting other crop and forage land to corn grain production. Yet, current times of increased income present an ideal opportunity to improve resource management. This will be necessary to permit continued profit und...

In the southeastern U.S. Coastal Plains, supplemental irrigation is required to reduce the impact of short‐term droughts and yield‐reducing plant water stress that can occur at least biennially. Sprinkler irrigation is commonly used to water agronomic crops in the region. Microirrigation is typically used for high value fruit and vegetable crops. In recent years and at some locations, microirri...

This paper presents simultaneous integration of different technologies such as the traditional dry-grind process to obtain ethanol from grain with the gasification of the corn stover followed by either syngas fermentation or catalytic mixed alcohols synthesis. The best integrated process when using the entire corn plant (18 kg/s of grain and 10.8 kg/s of stover) is the one in which the dry-grin...

Ethanol produced from biomass, such as corn grain or sugar cane, is a renewable fuel that helps lessen dependence on petroleum-based fossil fuels. Currently, the majority of ethanol production in the United States utilizes corn grain, which supplied about 14 billion gallons of ethanol to the market in 2012. In the near future, corn supplies for ethanol are expected to be limited due to concerns...

Three-dimensional temporal and spatial distributions of adult Rhyzopertha dominica (F.) at adult densities of 1.0, 5.0, and 10.0 adults per kg grain and at 20 +/- 1, 25 +/- 1, and 30 +/- 1 degrees C were determined in 1.5 t bins filled with wheat (Triticum aestivum L.) with 11.0 +/- 0.8, 13.0 +/- 0.6, and 15.0 +/- 0.5% moisture content (wet basis) or corn (Zea mays L.) with 13.0 +/- 0.2% moistu...

We conducted two experiments to evaluate the effects of corn supplementation, source of corn, and corn particle size on performance and nutrient utilization of lactating dairy cows. In experiment 1, treatments were 1) direct-cut grass-legume forage without supplement, 2) direct-cut forage plus 10 kg DM of ground dry shelled corn-based concentrate, and 3) direct-cut forage plus 10 kg DM of coars...

Performance responses to steam flaking flint corn as well as to the addition of roughage to finishing diets composed of whole flint corn were evaluated. Ninety-six Nellore bulls were stratified by initial BW (373 ± 11 kg) and randomly allotted to 16 feedlot pens (6 bulls/pen) in a randomized complete block design with 4 replicates/treatment. Dietary treatments for the 86-d feeding trial consist...
