  • Hairy Vetch management for no-till organic corn production

    Rolling-crimping to control hairy vetch (Vicia villosa Roth) may make organic no-till corn (Zea mays L.) possible. This study investigated how rolling-crimping date and growth stage of the cover crop affected hairy vetch control and if a rolled-crimped hairy vetch cover crop could supply weed control for no-till corn. Hairy vetch was planted in late August and was rolled and crimped and planted ...

  • Biocontrol of aspergillus flavus and aflatoxin b1 production in corn

    Aspergillus flavus and Aspergillus parasiticus are the most important aflatoxin-producing filamentous fungi. They can occur in several plant products, like spices, cereals and oily seeds (Jelinek 1998, Pittet, 1998 and Lewellyn, 1992). Aflatoxins (AF) are secondary metabolites with a high carcinogenic potential, especially in liver tissue. In addition the aflatoxins possess an acute toxicity at ...

  • Evaluation of in-season Nitrogen management strategies for corn production

    Nitrogen is an important and costly input for corn (Zea mays L.) production. With rising prices and environmental concerns, producers are looking for ways to better manage N fertilization. A project designed to evaluate in-season N management strategies for adjusting N rate was conducted in 30 Iowa cornfields from 2004 to 2006. Nitrogen rates applied preplant or early sidedress (PRE-N) and corn ...

  • Corn Production in the Bowen Food Basin - Case Study

    In Bowen, Queensland, in 2010, Hibrix was compared with a high NPK mineral fertiliser program for the production of maize cv. Hycorn 675IT on an alluvial sandy loam soil irrigated via sub-surface drip tape. At commercial harvest, cobs from 20 randomly selected plants per plot from were harvested, weighed and the length, girth at the cob base and length of tip not filled with kernels was measured. ...

  • Corn, a Vital Staple Food in Africa

    Africa contributes the least to global warming than any other continent. However, it suffers greatly from some of the more serious impacts of climate changes. The statistics are shocking: Africa emits roughly 4% of greenhouse gas emissions, while the United States emits 23% of the total global greenhouse gasses. Unfortunately, along with Asia, Africa is the region where crop production is the ...

  • Harvesting Corn Stover and Soil Quality

    Corn stover, left in fields after corn grain harvest, has been identified as a potential feedstock to help supply biofuel needed to offset a portion of the 14 million barrels of oils consumed daily by the U.S. transportation sector. It was projected to supply 256 million tons of the 1.4 billion tons of biomass (232 million Mg out of 1.3 billion Mg) estimated to be available each year. Corn stover ...

  • Corn stover using as a fuel in america

    In the world, US, Mexico, Brazil, Argentina, South Africa, Egypt, Kenya, Ghana, Zimbabwe, and so on, many countries grow corn, Case Study of Mozambique. Mozambique's main food crops are corn, rice, sorghum and cassava, corn is the staple food of Africans across the country are producing. Both of Corn stover and Corncob can be biomass fuel like straw, Corn stover biomass fuel boiler and corncob ...

  • Impact of defoliation on corn forage quality

    Hail damage can be a serious problem on corn (Zea mays L.) grown for silage. The value of corn grown for silage is a function of both the yield and quality of the forage produced. An improved understanding of the effects of defoliation on forage quality would improve the ability of agronomists, farmers, and crop insurance adjusters to assess the economic impact of hail damage to corn harvested ...

  • Controlling Barnyardgrass with Corn Hybrid Selection

    Barnyardgrass is a summer annual grass weed with a global impact on corn production.  Yield losses due to barnyardgrass competition have been estimated up to 45% or more for crops such as cotton and corn. Besides corn, it can also be a serious weed pest in rice, soybean, sugarbeet, cotton, and corn. Integrated weed management techniques can be used for control of barnyardgrass in corn. High ...

  • How to Choose a Corn Combine Harvester

    A corn combine harvester is a machine used for the corn harvest which both improves the harvest efficient and saves labor cost. Currently there are a variety of corn harvesters in the market, then how to choose a suitable ...

  • Growth analysis of biomass production in sole-crop and double-crop corn systems

    Increased biomass productivity could be achieved through double-cropping if extended growth duration could be realized with minimal reductions in growth efficiency relative to sole-cropping. To test this hypothesis, functional growth analysis was used to assess the relative importance of photosynthetic duration and efficiency in determining biomass production by sole-crop corn (Zea mays L.; SC) ...

  • Sensitivity of chlorophyll meters for diagnosing nitrogen deficiencies of corn in production agriculture

    Chlorophyll meters have been widely used to diagnose N deficiencies in research trials and to help refine N fertilizer recommendations in production agriculture. The diagnoses are based on the assumption that chlorophyll meters can detect a wide range of N deficiencies under field conditions according to relationships between chlorophyll meter readings (CMRs) and yield responses to N ...

  • Nitrous oxide production in an eastern corn belt soil: sources and redox range

    Nitrous oxide derived from soils is a main contributor to the greenhouse gas effect and a precursor to ozone-depleting substrates; however, the source processes and interacting controls are not well established. This study was conducted to estimate the magnitude and source (nitrification vs. denitrification) of N2O production as affected by the form of N fertilizer, soil water content, and redox ...

  • Planting date and cultivar effects on grain yield in dryland corn production

    Corn (Zea mays L.) production is gradually spreading into the Sudan savanna zone of West Africa where production is limited by erratic and inadequate rainfall. To increase corn production, production practices should be properly designed to minimize the effects of low precipitation and high temperatures that characterize the zone. A study, to determine the performance of late (120 d), early (90 ...

  • Zone tillage depth affects yield and economics of corn silage production

    Increasing numbers of dairies in northeastern United States are classified as confined animal feeding operations (CAFOs). Many dairy farmers in New York (NY) abandoned conventional and adopted zone tillage (ZT) in 4-yr corn (Zea mays L.) silage-alfalfa (Medicago sativa L.) rotations on highly erodible land to comply with NY CAFO plans. Farmers now question optimum ZT depth because of increased ...

  • Dairy manure compost effects on corn silage production and soil properties

    Accumulation of dairy manure compost has created a need to identify alternative uses for this plant nutrient source. This field study determined compost effects on corn (Zea mays L.) silage production, nutritive value, and soil characteristics for three growing seasons following incorporation of dairy manure compost at 0, 35, 70, and 105 Mg dry matter (DM) ha–1. Yields from subplots receiving ...

  • Linking Wisconsin dairy and grain farms via manure transfer for corn production

    One relatively under-used manure management strategy employed by dairy farmers is to transport and apply manure onto the fields of nearby grain farmers. While this system offers advantages to both parties, little of the existing research on manure management has been conducted on grain farms. As part of an effort to link grain and livestock farms in southern Wisconsin, 20 on-farm trials were ...

  • Evaluation of compost for use as a soil amendment in corn and soybean production

    The purpose of this research project was to 1) evaluate rate of compost application and 2) to compare compost with uncomposted raw material and inorganic fertilizer N application upon maize and soybean growth and productivity, and upon soil characteristics. During the first three years of the study, the source of uncomposted material and compost was food waste and ground newsprint. During years 4 ...

  • Temperature Monitoring Seed Corn in Drying Silos

    Producing quality seed corn takes much more effort than simply planting and harvesting. Agricultural producers understand how the time and temperature during the drying cycle of their seed corn affects both product quality and energy consumption. To optimize energy use and product quality, producers must be able to gather and view the time and temperature during the seeds’ drying phase. If ...
