in order to evaluate the yield and advantage of two- and three-species intercropping of sunflower with corn and soybean, an experiment was conducted at the research farm of faculty of agriculture of tabriz university in tabriz, iran 2011. the experiment was arranged based on randomized completely block design with 6 treatments and three replications. treatments were included the pure stand of s...

Different agricultural practices may have substantial impacts on crop physiology and yield. However, it is still not entirely clear how multiple agricultural practices such as tillage, biochar and different nutrient applications could influence corn physiology and yield. We conducted a three-year field experiment to study the responses of corn physiology, yield, and soil respiration to six diff...

Twelve field trials were conducted over a three-year period (2010, 2011, 2012) at different locations in southwestern Ontario, Canada to compare various two-pass weed management strategies in glyphosate-resistant corn for crop injury, weed control, environmental impact, corn yield and profit margin. No visible injury resulted from the herbicide treatments evaluated. One early postemergence (EPO...

This research paper uses partially historical corn yields of each county over five states as training set for calibrating alternative yield models including single parametric distributions, nonparametric distributions, semiparametric distributions, mixing models, and other nontraditional models. The calibrated models are applied to predict the yield of the most recent eight years in historical ...

An accurate and management sensitive simulation model for tile-drained Midwestern soils is needed to optimize the use of agricultural management practices (e.g., winter cover crops) to reduce nitrate leaching without adversely affecting corn yield. Our objectives were to enhance the Agricultural Production Systems Simulator (APSIM) for tile drainage, test the modified model for several manageme...

The milling of corn for the production of food constituents results in a number of low-value co-products. Two of the major co-products produced by this operation are corn bran and corn fiber, which currently have low commercial value. This review focuses on current and prospective research surrounding the utilization of corn fiber and corn bran in the production of potentially higher-value food...

crucial for the survival of agriculture in northeastern Colorado. Improper N and irrigation management are major factors contribThe relationships of corn yield and nitrate leaching uting to water quality and shortage problems in the Great Plains. with irrigation, N fertilization, and plant population This study was conducted on the Irrigation Research Farm in Yuma, have been extensively investi...

Over the last 70 years, national corn yield gains have occurred because of superior genetic yield potentials and management improvements such as improved water management, higher plant densities, and earlier planting dates. Some management recommendations, such as those from seed companies that promote optimum plant densities, are often environment, hybrid, and/or yield-range specific. Nitrogen...
