Irrigated Corn Verification Fields are nearly mature, but did require a final irrigation this week to provide ample moisture to sustain the crop to physiological maturity. Some slight root lodging also recently occurred, but otherwise harvest progress should commence soon. Late-planted dryland fields still have a long way to go and are under drought stress.
Over the past 7 days, numerous cotton fields have been determined to be infected with bacterial blight, caused by Xanthomonas axonopodis pv. malvacearum (formerly Xanthomonas campestris pv. malvacearum). In addition to the growing number of acres in MS having been
Much of our late March planted irrigated corn is now reaching dent stage and will continue to fill kernels for another 20 days, if we help it do so. Therefore, you do not want to forgo any practices which may mitigate stress or pest issues yet. This article highlights irrigation needs and termination during the final growth stages.
Despite Mississippi generally receiving abundant yearly rainfall, we often experience substantial drought stress growing corn. The timing of rainfall and the ability of our soils to store moisture are critical to corn productivity. This article explains how drought stress and irrigation management may influence corn productivity during the early grain filling stages.
2011 is shaping up to be one of the more challenging years we have faced in some time. While no year can be considered normal, difficult weather conditions have tested the mettle of many this year. Flooding, delaying planting, and
MSU Extension Service and MAFES researchers have compiled the following suggestions and information regarding replanting and managing row crops after the flood. Also included is post-flood crop insurance information.
One of the current corn research initiatives at Mississippi State University is a project evaluating corn productivity to later than normal planting dates, particularly when grown with irrigation. The preliminary results may be pleasantly surprising for some growers stricken with stand loss or delayed by rainfall.
One of the objectives of this program is to identify key production limitations, so the Mississippi State University Extension Service and Experiment Station can better direct efforts to develop innovations for our specific problems. This is a summary of such limitations documented during the past few years.
The 2010 Row Crop Short Course was held at Mississippi State University on December 6 – 8, 2010. As we expanded the Short Course in 2009, we also have adopted technology to record the oral and visual portions of the presentations.
