Sunbelt Expo is a valuable location for south Georgia forage

[ad_1]

The Sunbelt Ag Expo Darrell Williams Analysis Farms gives an distinctive alternative to focus on forage analysis in south Georgia. These hayfields present an outside classroom for UGA Extension county brokers in-service trainings, producer subject days and collaborative business occasions.

There are a number of demonstrations and on-going analysis trials in progress on the farm to deal with fundamental forage wants along with evaluating the combination of novel weed and bug administration methods into forage techniques. The 2-acre bermudagrass backyard gives a field-scale comparability of the six hottest bermudagrass varieties within the Southeast. Right here producers can work together with and consider these completely different varieties earlier than choosing the most suitable choice for their very own farm.

This space is additionally used for large-plot analysis trials to raised simulate the yield influence of the bermudagrass stem maggot, or BSM, that will be noticed on-farm. The BSM has prompted important yield loss in all six varieties since 2017, however a greater % injury was all the time noticed within the 4 finer-textured varieties (Alicia, Coastal, Russell, and Tifton 44). The largest takeaway from these research has been the affect of improved administration on decreasing BSM influence on forage yield. Cumulative yields have doubled between 2017 and 2020 due to improved forage and harvest administration, regardless of fluctuations in BSM populations within the late a part of the season (August – September) that historically result in 40% or extra yield loss.

Our subsequent analysis undertaking will use thermal imagery to evaluate the sphere and decide the optimum time to use pesticides. The purpose is to make use of cover temperature as an early indicator of plant stress to enhance effectiveness of insecticide functions for suppressing BSM populations.

A number of websites on the farm are getting used to check the brand new pre-emergent herbicide from Bayer Crop Science. It was profitable in controlling annual ryegrass and different winter weeds in bermudagrass. We’re additionally evaluating its effectiveness in controlling summer time annual weeds whereas establishing bermudagrass. A brand new subject of Tifton 85 bermudagrass was sprigged in June 2020. This subject won’t solely enhance the manufacturing potential of the farm, it will likely be used to display the significance of following institution pointers for a profitable stand. A brand new alfalfa subject might be seeded in 2022. Video from every of those institutions might be utilized in on-line instructional packages.
