Colquitt County Extension Corn and Sorghum On Farm Demonstrations

On farm demonstrations is a great way to generate research based information for growers to use and make decisions. Below are results from on farm corn and grain sorghum demonstrations that were conducted in Colquitt County last year.

Grain Sorghum Response to Fungicide

Harvesting grain sorghum plot August 2020

This study was conducted at the Sunbelt Ag Expo.  The plots was 12 rows wide and each treatment was replicated three times throughout the field.  The sorghum hybrid was Dyna-Gro 73-55.  Priaxor at 8 oz per acre applied boot stage.  Low disease pressure was noted at this site…Sorghum harvested with combine and industry weigh wagon.

Corn Response to Fungicide at V7

TreatmentBu/A at 15 % Moisture
TrivaPro 14 oz/A 225.66 A
Untreated 224.66 A

This demonstration consisted of two treatments. Each treatment was 12 rows wide and replicated three times.  Dynagro 58VC65. Low disease pressure in field.  Harvested with combine equipped with Climate Fieldview. Fungicide was applied over whole plot at VT.

This corn plot was planted on March 20th .  Infurrow treatments applied at a water volume of 5 GPA.  Each treatment was 6 rows wide and replicated three times.  Dynagro 58VC65 was the corn hybrid planted. Harvested with combine equipped with Climate Fieldview on August 13th. pH: 5.9, P = VH, K = H.

Corn plot was planted on March 26th.  4 row plots and replicated three times.  Terrel REV 28HR18.  Harvested with combine equipped with Climate Fieldview on August 10th. pH=6.3, P=VH, and K =M. Low nematode pressure was noted at this site.

The Colquitt County Extension office would like to thank the Sunbelt Ag Expo, Amvac, Bayer Crop Science, BASF, Syngenta, Nutrien Ag, and DynaGro for all the support on the above projects.
