Brassica carinata is an annual oilseed crop used for the commercial production of jet fuel, animal feed, and valuable chemicals. Carinata has recently been introduced in Georgia as a cool season cash crop with cover crop benefits. Because it is grown in the winter, it has the potential to sustain and recover from frost damage. This publication outlines conditions that can cause frost damage and how the plant will react to this stress.
This resource was written in collaboration with the University of Florida’s Institute of Food and Agricultural Sciences Extension, the U.S. Department of Agriculture National Institute of Food and Agriculture, and the Southeast Partnership for Advanced Renewables from Carinata.

The geographic and environmental diversity of Georgia allows for the extensive use of both cool and warm season grass species. In general, cool season grass species provide higher nutritional quality than warm season grasses. In contrast, warm season grasses generally yield more than cool season grasses. Each type and species, however, offers its own unique qualities and benefits to the forage system. In this section, the most important grass species in Georgia are introduced and discussed.

Legume species add significantly to forage systems in Georgia. They are an excellent source of high quality forage, and are generally very digestible and contain high levels of crude protein (CP). Many legumes also provide substantial forage yields. Perhaps most importantly, legumes and the rhizobium bacteria that colonize nodules on their roots provide an important source of biologically-fixed nitrogen (N). This publication presents information about the most important legume species grown for forage in Georgia.

This is a biennial publication containing the proceedings of the turfgrass field day carried out at the UGA Griffin campus every other year. The guide provides professionals with continuous, real-time access to the latest up-to-date information about turfgrass research studies, products, and turfgrass Extension activities, programs, and outreach. Topics will include, but are not limited to, crop and soil science, agronomy, weed science, plant pathology, entomology, economics, tissue culture, urban agriculture, irrigation, and student posters.

Haiti Peanut Research Report
This report summarizes the findings of field trials and basic data collected in Haiti under the Feed the Future Peanut & Mycotoxin Innovation Lab project from 2014-2017. The focus of the research was to improve peanut productivity through management options for foliar diseases, low soil fertility, and other yield-limiting agronomic factors.

Drip, trickle, microemitters, and subsurface irrigation systems are considered low-volume irrigation. Low-volume irrigation systems are designed to improve irrigation efficiency, delivering water to the crop accurately with minimal water loss. Irrigation efficiency can be categorized into two main concepts: water loss and uniform application. If water loss is significant, or application uniformity is poor, efficiency will be low. Generally, the most significant loss of irrigation water is from overwatering, where the water percolates below the root zone, or from runoff. With good management, losses due to leaks, system drainage, and flushing of filters and lateral lines should not exceed 1%. Low-volume systems have the opportunity to achieve efficiency, and under careful management, will minimize losses from overirrigation. However, using low-volume systems requires increased irrigation frequency and soil moisture monitoring should be used to improve water-use efficiency. This publication covers system design, system efficiencies, components, chemical applications, diseases related to irrigation, and soil moisture monitoring.
