Field Crops, Forage and Turfgrass Production

In 2010, the UGA cotton agronomists implemented this variety testing program. Our industry partners were asked to provide their most well-suited varieties for Georgia. Historically, the varieties evaluated in this trial have accounted for nearly 75% of the planted acreage in Georgia in the same year. These varieties were planted in replicated trials in growers’ fields throughout cotton-producing regions of Georgia, through coordination with the county Extension agents. The trials were managed and replicated by the grower with the assistance of the coordinating county agent to achieve realistic and statistically sound results.

La bermuda es una planta perenne de estación cálida ampliamente utilizada para su uso como césped en el sudeste de los Estados Unidos.
[Although improved common (Cynodon dactylon (L.) Pers.) and hybrid bermudagrasses (Cynodon dactylon x C. transvaalensis Burtt-Davy) have desirable qualities as turfgrasses for heat, drought and wear tolerance, bermudagrass is a problematic weed when grown in mixed stands with other turf species. Selective control of bermudagrass is difficult but often warranted in order to maintain acceptable quality of the desired turfgrass species. This publication describes bermudagrass control methods for Southern lawns.]

Aflatoxin is a naturally occurring toxin produced by the fungus Aspergillus flavus. The fungus can be recognized by a gray-green or yellow-green mold growing on corn kernels in the field or in storage. Plant stress due to drought, heat or insect damage during fungus growth usually increases aflatoxin levels. Aflatoxin contamination will reduce feeding value and hinder sales. Because it is extremely poisonous to warm-blooded animals even at relatively low levels, grain handling facilities often check for the presence of the toxin before purchasing corn.

La lespedeza común (Kummerowia striata (Thunb.) Schind syn. Lespedeza striata) es una leguminosa anual de verano sin organización en sus ramificaciones, que es una maleza problemática en céspedes de jardines residenciales así como en otras áreas de césped.
[Common lespedeza (Kummerowia striata (Thunb.) Schind syn. Lespedeza striata) is a freely branched, summer annual legume that is a problematic weed in lawns and other turf areas. This publication describes ways to identify and control Lespedeza in turfgrass, including cultural control methods, preemergence herbicides and postemergence herbicides.]

Annual bluegrass (Poa annua L.) is a problematic winter annual weed in residential turf. Compared to most turfgrasses, annual bluegrass has a lighter green color, coarser leaf texture and produces unsightly seedheads. Contrary to its name, both annual (live for one season) and perennial (live for many seasons) biotypes of annual bluegrass may be found in turf. This publication describes methods of control for annual bluegrass in residential turfgrass lawns.

Cotton defoliation is a complex production decision with many chemical options to consider. Harvest aids are utilized to prepare the crop for machine harvest, and timely defoliation and harvest of cotton can reduce weathering losses (yield and quality) and decrease trash in the lint. A basic knowledge of crop development and maturity as well as an understanding of the physiological effects of harvest aids on cotton plants is necessary in making decisions concerning defoliation.

Aeration conditions grain and seed by lowering the temperature of the material and equalizing the temperature within the storage structure. This prevents moisture migration and condensation and can reduce losses during storage.
