The past efforts made on the corn cleaning dynamics were reviewed. Based on Discrete Element Method model, a simulation method for corn cleaning dynamics was then proposed, composing the following design factors: 1. 2-D discrete model and its related factors; 2. parities and magnitude of computation, consideration of the two factors upon application; 3. test platform design. The implementation ...

The production of deoxynivalenol (DONI) on rice, corn, wheat, and barley grains by Fusarium graminearum Schw. NRRL 5883 was investigated. Highest yields (91.9-202 ppm) were obtained on rice; yields on the other substrates were: corn (34.1-84.5 ppm), wheat (3.6-24.4 ppm), and barley (0-6.6 ppm). Fifty isolates of Fusarium from corn inoculated in the field in 1979 with a mixture of strains of F. ...

harvesting corn created annually a large amount of organic waste, which could be a suitable initial substrate for vermicomposting due to its high c/n ratio. the present study was aimed for recycling of corn residues and production of good quality vermicompost, after processing by eisenia fetida. the setup of experiments was conducted with 40, 60 and 80% of corn residue, compost, cow dung and pa...

The corn and soybean markets have been bidding for acreage due to a bullish final crop report for 2006. With biofuels creating new markets for corn and soybeans, this demand-driven market may continue to provide marketing opportunities. Currently, the major decision facing producers is determining the enterprise mix for 2007. This memo compares the Returns over Variable Costs for corn and peanu...

A twoto four-fold increase in corn prices in recent years over historical trends has prompted many questions about alternatives to corn for dairy rations. As corn is a low protein high energy feedstuff, its continued use even with high prices or concern over its partial replacement is mainly confined to rations for lactating cows where meeting the energy requirements of milk production is impor...

The considerably low β-glucosidase activity : FPA ratio of 0.5-0.6 represented by the enzyme complex of Trichoderma reesei RUT C30 results in poor hydrolysis potential. To overcome this problem culture conditions were developed to enhance β-glucosidase production. Mandels’ medium supplemented with tris-maleate buffer proved to be efficient for cellulase production with elevated β-glucosidase ac...

The main objective of this study was to isolate the fungal strain for enhanced production of xylanase using different agro-residues and fruit peels by solid state fermentation and its potentiality was tested on the pretreated corn cob. Fermentation was carried out with Trichoderma koeningi isolate using untreated and pretreated corn cob supplemented with pineapple peel powder showed higher prod...

Corn production, and its associated inputs, is a relatively large source of greenhouse gas emissions and uses significant amounts of water and land, thus contributing to climate change, fossil fuel depletion, local air pollutants, and local water scarcity. As large consumers of this corn, corporations in the ethanol and animal protein industries are increasingly assessing and reporting sustaina...

the effect of different levels of alfalfa hay and corn silage, in early lactation diet, on milk production and on milk components in holstein cows was investigated. fifteen holstein cows (37 ±10 dim) were taken in a completely randomized design experiment, lasting for 9 weeks. three levels of hay and corn silage namely: 1) 10% alfalfa -30% silage corn (diet 1), 2) 20% alfalfa -20% silage corn (...
