We evaluated the effects of irrigated crop management practices on nitrous oxide (N(2)O) emissions from soil. Emissions were monitored from several irrigated cropping systems receiving N fertilizer rates ranging from 0 to 246 kg N ha(-1) during the 2005 and 2006 growing seasons. Cropping systems included conventional-till (CT) continuous corn (Zea mays L.), no-till (NT) continuous corn, NT corn...

In the United States, corn (Zea mays L.) stover has been targeted for second generation fuel production and other bio-products. Our objective was to characterize sugar and structural composition as a function of vertical distribution of corn stover (leaves and stalk) that was sampled at physiological maturity and about three weeks later from multiple USA locations. A small subset of samples was...

During past decades, enterprise systems (ES) are becoming increasingly popular and numerous IS researchers have investigated the adoption of ES. Most of them investigated ERP adoption at the firm level. Few papers investigate ES adoption at multi-level. On the basis of TOE model, this paper propose a multi-level framework that specifies the country-level, the firm-level, and the cross-level eff...

The western corn rootworm, Diabrotica virgifera virgifera (LeConte), is a major pest of maize, Zea mays L., in the United States and Europe, and it is likely to increase in importance as a trend toward increasednonrotatedmaize favors larger rootwormpopulations.Options for rootworm management in nonrotated maize in Europe and in nontransgenic “refuge” areas in countries that permit transgenic ma...

A simple approach was developed to predict corn yields using the MoDerate Resolution Imaging Spectroradiometer (MODIS) data product from two geographically separate major corn crop production regions: Illinois, USA and Heilongjiang, China. The MOD09A1 data, which are eight-day interval surface reflectance data, were obtained from day of the year (DOY) 89 to 337 to calculate the leaf area index ...

How an agent (or a firm, an investor, a financial market) evaluates a contingent claim, say a European type of derivatives X, with maturity t? In this paper we study a dynamic evaluation of this problem. We denote by {Ft}t≥0, the information acquired by this agent. The value X is known at the maturity t means that X is an Ft–measurable random variable. We denote by Es,t[X] the evaluated value o...

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...

Insect-protected corn hybrids containing Cry insecticidal proteins derived from Bacillus thuringiensis have protection from target pests and provide effective management of insect resistance. MON 89034 hybrids have been developed that produce both the Cry1A.105 and Cry2Ab2 proteins, which provide two independent modes of insecticidal action against the European corn borer ( Ostrinia nubilalis )...
