10 ideas for improving bean yields
Posted Thursday, February 2, at 3:04 PM The various farm publications often offer tips on how to produce higher soybean yields. Depending on which article you see, the number of tips can range from as few as 5 to 20 tips. All of the tips have a lot of commonality and involve common sense decisions...
New herbicides coming for 2012 Fierce is a preemergence herbicide for use in soybeans and reduced-tillage field corn. It has shown residual control of tough weeds, including weeds like glyphosate-, ALS- and triazine resistant Palmer Amaranth, waterhemp, and annual grasses. Valent anticipates EPA registration for 2012...
Getting to 300 per bushels per acre The world population is expected to reach 9 billion people by possibly 2030. In order to feed this population it is predicted that corn will need to average 300 bushel per acre to feed them. Over the last 55 years, the average rate of increase in corn yield has been 1.9 bushels per acre...
Managing volunteer corn may be a problem in 2012 Wind storms late in the growing season of 2011 as well as fields that were flooded resulted in a lot of down corn in the area. The losses associated with the down corn and it's harvesting resulted in concerns over volunteer corn in next season's crop and the possible options to control it...
Palmer amaranth can cause considerable yield reduction Palmer amaranth is a very competitive weed. In some fields with "scattered" pigweed plants, the control was considered good. In a study conducted in soybeans several years ago, one Palmer in 80 feet of soybean row reduced yield 17 percent and one palmer in 60 foot of soybean row reduced yield 27 percent...
Flooded field syndrome could be an issue in 2012 Soils can exhibit a condition called "Flooded Soil Syndrome" after extensive flooding due to the lack of plant growth in submerged areas. This condition exists where crops planted the year after an extended period with no plant growth exhibit reduced early growth and yield. ...
What weeds should you watch for? Good weed control starts by knowing what the predominant weed species problems for each field. Knowing which are the worst weeds will aid in choosing the best product or mix of products to control them. Most major weed and herbicide resistance problems in corn vary by location across the corn belt, within a state, and even within different fields. The following six weeds have been ranked as being the most difficult to control...
Check grain bins for insect infestation Now that harvest is over, you can relax some. However with warmer than normal fall temperatures, developing grain insect populations in on-farm grain storage becomes a possibility. Insect infestations can develop in as little as 3 to 6 weeks following initiation of grain storage. ...
Selecting the right seed It is that time of year when producers start making their selections for next year's corn hybrids and soybean varieties. With all of the corn hybrid and soybean technologies available to growers, an increased number of choices has produced a growing challenge in identifying which traits will provide maximum performance and yield in a grower's specific field. ...
Fall anhydrous ammonia application Soil temperatures are still above recommended levels (50 degrees and cooling 4-inch temperature) for the fall application of anhydrous ammonia. Another problem that is of concern is the dry soil. First, there are reports or remarks of the soil being so hard that it is difficult to the machinery to penetrate the soil. Secondly, is the question whether anhydrous should be applied to dry soils?...
New traits coming from seed companies will help with moisture, fertilization and chemicals As you start planning for next year's crop, producers need to know what new traits may be available or will be available in the future to use in their management plants. By knowing what may be available to manage current and future needs, the producer can evaluate current practices and challenges to plan better for future crops...
Some old solutions to new weed-control problems Weed resistance to herbicides has become a big problem. Weeds are the single most economically important pest producers have to manage according to Michel Owen, extension specialist at Iowa State University. And weed management is not what it used to be...
Dry weather can affect results of early fall soil tests The exceptionally dry fall conditions due to low rainfall, especially since corn and soybean physiological maturity may affect the quality of soil samples and soil-test results. The first concern is with obtaining the actual soil sample. Sampling under very dry conditions may increase soil sampling error because of the difficulty of controlling sample depth and proper soil collection. ...
There are several considerations when applying fertilizer in the fall Harvest is progressing steadily with the continued warm and dry weather opening up fields for the application of fertilizer for next year. Some lime and potash and phosphate have been applied on a limited basis. Soil testing is the best way to determine pH and the nutrient needs of the next crop...
Use your time in combine seat to scout fields Harvest provides an opportunity to scout your fields from an advantageous position. As you travel through the field, you can observe various types of problems that may have occurred during the growing season. Weeds that were not controlled would be one of the most obvious problems that will show up...
Managing corn stover with Fall nitrogen applications Management of corn stover has become more of a concern as new hybrids produce stronger stalks, relatively larger amounts of biomass, more corn-on-corn acres are planted and less tillage is done. Stronger stalks are desirable to help with the standability of the crop. ...
Carefully check for drought-stressed corn Corn harvest has started in some local areas, mainly to crop that has suffered severe stress from the various weather conditions this summer. South of I-70 some drought stressed corn has been harvested for over a week. Yields of 60 to 75 bushel per acre have been reported. In addition to the drought and heat stressed corn, wind damaged corn has also accelerated the need to harvest earlier...
Soybean podworms can strip field quickly Soybean podworms have been reported in some parts of the state. This pest is known as the corn earworm in corn or the soybean podworm in soybeans. University of Missouri Extension specialists recommend scouting fields now to prevent damage to the crop. According to Wayne Bailey, MU Extension entomologist, if podworms are high enough in number they will take off all the pods in a field...
What is causing yellow flash in soybeans? The yellow flash that we have seen in soybeans this year seems to be lasting longer than usual. We usually see some of this yellow where there is an overlap or a particularly high rate of glyphosate used. Stressed beans will flash more readily and with the heat and dry weather stress that we have experienced many fields have flashed even with typical rates of glyphosate usage...
Hot, dry weather always a concern The heat and dry weather is a concern for crop producers. Crops are now on the defensive. This can be seen in the rolling of corn leaves and flipping of soybean leaves. Crops south of I-70 seem to be more severely affected than crops north of I-70. As you go further south from I-70 there are patches in both corn and soybean fields where plants are dead as well as fields in general suffering from severe drought stress...
