Extractions: NCDC Climate Monitoring Climate Indices / CMSI / Search Help Crop Moisture Stress Index Corn Moisture Stress Index Soybean Moisture Stress Index The Moisture Stress Index for corn and soybean crops is a measure of the effects of drought and catastrophic wetness on national crop yield and is calculated through the use of a drought index (the Palmer Z Index) and annual average crop productivity values within each U.S. climate division. Moisture stress, either a lack or an abundance of soil moisture during critical phases of the crop growth and development cycle, affects US average crop yield, particularly when moisture stress occurs in the most highly productive crop growing areas. Soil moisture conditions in July and August were found to be the best indicators of average crop yield for corn and soybeans, and as such, are used in creating the Moisture Stress Index. Calculations of the Moisture Stress Index are based on (1) the extent of severe to catastrophic drought or catastrophic wetness within the crop growing regions, i.e., those climate divisions with a Z Index value = +5, and (2) the average annual crop productivity* of each climate division within the crop growing region. Figure 1 is an example of short-term soil moisture conditions as measured by the monthly Palmer Z Index, while figures 2 and 3 show the 10-year average crop productivity values within the crop and soybean growing regions respectively.

Extractions: Skip the navigation header body We don't usually think of Kansas producing a lot of corn, but this year corn produced more bushels than wheat! Corn is a grassy crop as well as a cereal grain crop. Corn is another important Kansas crop. This year farmers planted 3.4 million acres of corn. Corn is also a monocotyledon . Mono means one and a cotyledon is a specialized leaf. The cotyledon in corn is found in the inner white region of the seed. The outer yellow layer is the endosperm. The endosperm is the energy source for germination and initial growth of the plant. Corn can be used for human consumption or a feed grain for animals. Can you think of products that we use that are made from corn?

http://www.pbs.org/wgbh/harvest/engineer/

Extractions: From cucumbers and carrots to white rice and wheat, we humans have altered the genes of almost every food we eat. For almost 10,000 years we've been engineering plants by keeping the seeds from the best crops and planting those the next season. Following this practice year after year has resulted in a slow but steady change and a substantial cumulative effect. We've been altering the genetic makeup of crops by cross-pollinating, too. About 8,000 years ago, for example, farmers in Central America crossed two mutant strains of a weedy-looking plant called Balsas teosinte and produced the first corn on the cob. We've had success with the methods mentioned above (especially cross-pollinating), but because they rely on the random mixing of all of a plant's tens of thousands of genes, the odds of producing a crop with a desired trait is akin to winning a lottery. Today scientists can produce a change quickly by selecting a single gene that may result in a desired trait and inserting that gene directly into the chromosome of an organism. Amazingly, genes from organisms as dissimilar as bacteria and plants can be successfully inserted into each other. These activities let you compare the traditional method of selective breeding with one of the latest transgenic methods.

Extractions: CROPS The 2000 crop season got off to a great start due to cooperative weather during most of the month of April and prior months. Crops were planted earlier and at a more rapid pace than ever before. Fifty-nine percent of the oats were already planted by April 2 nd . This compares with 55% in 1999 and the five year average of 25%. By April 30, 58% of the corn crop had been planted. This compares to 8% in 1999 and the five year average of 25%. Six percent of the soybeans were in the ground by this date. This compares to 0% in 1999 and the five year average of 2%. Rainfall was adequate across the state during the growing season with the southern half of the state receiving more rain than the northern half. The wheat crop developed ahead of normal with a minimal of disease problems this year due to the mild temperatures and adequate moisture during the spring. By May 28 th , the crop had developed to 78% filled, compared to 56% in 1999, and a five year average of 40%. An estimated 13% was turning yellow compared with 5% in 1999 and the five-year average of 6%. The crop was rated 17% excellent, 54% good, 22% fair, 5% poor, and 2% very poor on May 26. Harvest began ahead of normal in the first week of September but was slowed during the month of September and the first part of October due to frequent rain showers. However, nearly ideal weather conditions in late October allowed farmers to completely wrap up harvest by the middle of November. As of November 12

Extractions: B usiness O pportunities REGISTER HERE LOGIN Beans and fungus may improve corn crop without expensive fertilizer Corn, the preferred staple crop in many countries, requires large amounts of nitrogen for its growth. Usually fertilizer is necessary to sustain good yields. A Penn State graduate student, Ylva Besmer, is trying to find ways to improve corn yield for subsistence farmers in Zimbabwe without fertilizer. "The government of Zimbabwe no longer provides a subsidy for fertilizer, resulting in significantly lower corn yields" says Besmer, a doctoral candidate in ecology. "The old-fashion use of legumes (members of the bean family) in crop rotations may prove to be a solution to this problem because of their ability to fix nitrogen and, thus, provide nitrogen for subsequently grown corn. We have shown in Zimbabwe, however, that legume growth and nitrogen fixation can be limited by the availability of phosphorus in the soil." In order to improve nitrogen fixation in legumes, somehow phosphorus availability has to be increased.

http://www.aphis.usda.gov/brs/corn.html

Extractions: Zea mays Linnaeus, known as maize throughout most of the world, and as corn in the United States, is a large, annual, monoecious grass, that is grown for animal feed, silage, human grain, vegetable oil, sugar syrups, and other miscellaneous uses. It is the premier cash crop in the United States, and its cultivation, genetics, processing, financing, and distribution on a national and international scale is pervasive and complex. World production in 1987/1988 was 439 million metric tons, of which the United States produced 179, China 76, Brazil 23, and France 12. Corn is grown commercially in almost all States of the United States (Jewell, 1989). United States production in 1987 was 7064 million bushels, of which the top State producers were Iowa (1306), Illinois (1201), Nebraska (812), Minnesota (635), and Indiana (632). Corn has the highest value of production of any United States crop; 1987 value was 12.1 billion dollars, compared to soybeans at 10.4, hay at 9.1, wheat at 5.4, and cotton at 5.0. Corn has been cultivated since the earliest historic times from Peru to central North America. The region of origin is now presumed to be Mexico (Gould, 1968). Dispersal to the Old World is generally deemed to have occurred in the sixteenth and seventeenth centuries (Cobley and Steele, 1976); however, recent evidence indicates that dispersal to India may have occurred prior to the twelfth and thirteenth centuries by unknown means (Johannessen and Parker, 1989).

Extractions: Monsanto has developed genetically improved corn that protects against the European and southwestern corn borer, and genetically engineered cotton that protects against the bollworm. These innovative products not only increase crop yields but also dramatically reduce the need for applications on insecticides. They include Bollgard with Roundup Ready Cotton, Ingard Cotton and YieldGard Insect-Protected Corn. YieldGard Plus Corn YieldGard Plus corn provides growers with in-seed protection, allowing the corn plant to protect itself against the damaging Western and Northern corn rootworm larvae and the European corn borer. All YieldGard Plus corn hybrids will be sold with a seed treatment to offer broad-spectrum control of secondary insect pests such as wireworm, white grub, early flea beetle, and seed corn maggot. YieldGard Plus corn joins Monsanto's "YieldGard" family of insect-protected products for corn, which also includes YieldGard Corn Borer and YieldGard Rootworm corn. Following the necessary regulatory clearances on a state-level in the U.S. and receipt of the Japanese import approval, the YieldGard Plus technology will be made available for planting in corn hybrids through Monsanto's branded seed businesses - DEKALB and Asgrow - as well as through licensed, independent seed companies.

Extractions: Rob Wynstra (217)333-9446, e-mail: wynstra@uiuc.edu March 8, 2004 URBANAThe search for the cause of early season damage to a corn crop rarely includes submitting a soil sample for nematode analysis since it is widely believed that damaging levels of nematodes rarely occur in fine-textured soils. But, according to a recent survey in northwestern Illinois by integrated pest management and crops educators from University of Illinois Extension, nematodes can cause early season problems irrespective of soil type. "The educators teamed with commercial fertilizer dealers and other Extension personnel to be part of the team collecting soil samples," said Dave Feltes, IPM educator at the East Moline Center. "Forty-eight composite samples were collected from Whiteside, Henry, Brown, Bureau, Henderson, Menard and Hancock Counties and submitted for analysis. Both sandy and fine-textured soils were sampled." For all soil samples, the population of each nematode species was rated as insignificant, minimal, moderate, severe, or very severe in terms of the amount of damage they could cause to a corn crop. "Ratings of severe and very severe can cause corn yield losses of 50 percent or more, depending on soil and environmental conditions," Feltes said. "The results indicated that 79 percent of the samples were positive for soybean cyst nematode." He notes that 90 percent of the samples were positive for spiral nematodes with three of the 43 positive samples rated severe and four of the samples rated moderate in the amount of damage they could cause to a corn crop

Extractions: Printer Friendly Version E-Mail This Article Published on Friday, April 23, 2004 by the Los Angeles Times A Flood of U.S. Corn Rips at Mexico by Michael Pollan Americans have been talking a lot about trade this campaign season, about globalism's winners and losers, and especially about the export of American jobs. Yet even when globalism is working the way it's supposed to when Americans are exporting things like crops rather than jobs there can be a steep social and environmental cost. One of the ballyhooed successes of the North American Free Trade Agreement has been the opening of Mexico to American farmers, who are now selling millions of bushels of corn south of the border. But why would Mexico, whose people still subsist on maize (mostly in tortillas), whose farmers still grow more maize than any other crop, ever buy corn from an American farmer? Because he can produce it much more cheaply than any Mexican farmer can. Actually that's not quite right it's because he can sell it much more cheaply. This is largely because of U.S. agricultural policies. While one part of the U.S. government speaks of the need to alleviate Third World poverty, another is writing subsidy checks to American farmers, which encourages them to undersell Third World farmers.
