Conservation tillage with agronomic crops (i.e., cotton, corn, soybeans, etc.) has been successful in Georgia production. Such production practices have several benefits, the most notable being the elimination of soil erosion. Other benefits include but aren’t limited to increases in soil organic matter, maintaining a healthy rhizosphere (root-zone soil), reduction of riparian and waterway pollution, and water conservation.
Some examples of conservation tillage practices include no till, ridge till, and strip till. No–till production involves no tillage of field soils and leaves all of the previous crop residue on the soil surface. Ridge–till production involves building a ridge during cultivation, then scalping the ridge and sowing seed. The scalping process moves most of the previous–crop residue to the row middles, leaving a clean row for sowing. Strip–till production is when a narrow strip is tilled for each row that will be planted, leaving the row middles intact with the previous–crop residue. Strip–tillage may reduce yields if weeds in the untilled area are not killed, as these weeds will compete with the crop for water and nutrients. Although the planted row is free of previous crop residue, it may be advantageous to kill the cover crop to prevent it from competing for nutrients and water with the vegetable crop.

Cotton growth monitoring is vital to producing a healthy crop, making sure that the crop is growing on track, and that there are minimal stresses on the crop. Growth monitoring also can assist in making plant growth regulator (PGR) applications. PGR applications are complex, and many factors play into the decision of when to use them and at what rates. The goal of this publication is to discuss these factors and assist in determining when to make a PGR application.

Variety selection is one of the biggest decisions and investments cotton growers make each year. In 2010, the UGA Extension Cotton Agronomists implemented the UGA On-Farm Cotton Variety Evaluation Program to assist in this decision. Varieties are evaluated across a wide range of environments in the cotton producing regions of Georgia in cooperation with county agents and industry partners. The implementation of this program has made a tremendous impact on variety selection from year to year, and it will continue to have the same impact in the future.

Boom sprayer calibration using conventional methods (catching flow for certain time or distance) for large (60-90 ft; 54-72 nozzles) boom sprayers can be a time-consuming process. This short publication outlines steps to take to verify nozzle output and calibrate a boom sprayer, including tables with useful information on flow rates at multiple speeds for two common nozzle spacings and an equation for calculating rates if needed.

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.
