Inhibitions of cotton germination and early seedling growth by cover crop residues

 Cover crops have been used to suppress weeds, reduce erosion, and increase water infiltration for many years. While cover crops can improve soil quality and physical properties, integration of cover crops into row crop production-specifically cotton- remains challenging. One potential negative impact on cotton growth may come from allelopathy.  Allelopathy is defined as the direct or indirect harmful or beneficial effects of one plant on another through the production of chemical compounds that escape into the environment (Fig. 1). Although allelopathic toxicity of cover crops can suppress weeds and therefore assist in weed control, they may also suppress cotton germination and reduce stand. Little is currently known about the actual allelopathic effects of cover crops on germination and seedling growth of cotton. Proper selection of cover crop species and termination timing could potentially reduce the allelopathic toxicity which negatively impacts cotton germination and early seedling growth.

CORN HARVEST CONTINUES AT RAPID PACE

Spotty showers did little to slow field work. Corn harvest continued to proceed rapidly with many producers reporting better than average yields. Cotton harvest began on a limited scale, while soybean harvest picked up somewhat. Hay producers were busy with their final cutting for the season. Pasture conditions improved slightly as temperatures dropped a few degrees. There were 5.9 days suitable for field work. Topsoil moisture rated 3 percent very short, 23 percent short, 72 percent adequate, and 2 percent surplus. Subsoil moisture rated 8 percent very short, 25 percent short, 66 percent adequate, and 1 percent surplus. Continue reading at TN_09_17_18.  The U.S. Crop Progress report can be read at CropProg-09-17-2018.

Tennessee Market Highlights

Author: Chuck Danehower, Extension Area Specialist - Farm Management No Comments

Corn and soybeans were down; cotton and wheat were mixed for the week.

The major news this week was USDA’s updated yield estimates. Nationally, corn, soybean, and upland cotton yields were estimated at 181.3 bu/acre, 52.8 bu/acre, and 881 lb/acre. Corn and soybean estimates were revised up 2.9 bu/acre and 1.2 bu acre from last month – if realized both would be all-time records. Upland cotton yield was decreased 14 lb/ acre from last month.

The larger than anticipated, corn and soybean yields contributed to December corn and November soybeans setting new contract lows of $3.48/bu and $8.21/bu. With the large crop headed towards market and no foreseeable end to trade disruptions a further leg down in futures prices cannot be ruled out at this time.

RELEASED: September 12, 2018

September 1 Tennessee Crop Production Forecast

Corn production in Tennessee is forecast at 127 million bushels,  unchanged from the August forecast and up 5 percent from the previous crop. Yield was estimated at a record 174.0 bushels per acre, unchanged from last month and up 3.0 bushels from the 2017 level. Acres for harvest as grain were estimated at 730,000 acres, up 20,000 acres from 2017. U.S. corn production is forecast at 14.8 billion bushels, up 2 percent from the August forecast and up 2 percent from 2017. Based on conditions as of September 1, yields are expected to average 181.3 bushels per acre, up 2.9 bushels from last month and up 4.7 bushels from 2017.

Generic Base/Seed Cotton Program Meetings October 29-31

Author: Chuck Danehower, Extension Area Specialist - Farm Management No Comments

University of Tennessee Extension is hosting 5 meetings to assist producers and landowners with finalizing their decisions regarding generic base acres and seed cotton as a result of the Bipartisan Budget Act of 2018. The meetings will provide information on: updating yields, options for reallocating generic base, 2018 ARC and PLC program selection for seed cotton base acres, and the short & long term implications of the decisions for landowners and cotton, grain, and oilseed producers.

For producers and landowners that have already made reallocation and program election decisions, the meetings will provide an opportunity to review (and change) decisions based on: 1) updated 2018 county yield data; and 2) recent policy developments in the 2019-2023 Farm Bill negotiations.

The sign up deadline at FSA service centers is December 7th. Meetings will be held in Dyersburg, Somerville, Alamo, Brownsville, and Jackson (October 29-31; See Generic Base Meetings Flier 2018). We encourage attendees to register so we can get an accurate head count for meals.

MARKED PROGRESS MADE ON CORN, TOBACCO HARVEST

Dry weather last week paved the way for Tennessee growers to make marked progress on corn and tobacco harvest. Producer reported corn yields are better than earlier anticipated. Soybean harvest was just beginning last week and cotton was being defoliated. Plentiful amounts of hay was harvested and put up over the past week in most areas while in other areas, warmer temperatures have limited pasture growth and hay may need to be fed sooner this year. There were 5.5 days suitable for field work. Topsoil moisture rated 5 percent very short, 20 percent short, 69 percent adequate, and 6 percent surplus. Subsoil moisture rated 12 percent very short, 29 percent short, 56 percent adequate, and 3 percent surplus. Continue reading at TN_09_10_18. The U.S. Crop Progress report can be read at CropProg-09-11-2018.

Corn and soybeans were up; cotton and wheat were down for the week.

This week corn and soybean prices moved mostly sideways as markets are
awaiting the next round of USDA yield and production estimates. National and
Tennessee yields are anticipated to be record high for both corn and soybeans.
Current national average yield estimates from private companies are 177-182 bu/acre for corn and 50-54 bu/acre for soybeans. Current USDA estimates are national average yield of 178.4 bu/acre and 51.6 bu/acre and for Tennessee 174 bu/acre and 49 bu/acre. A one bushel increase or decrease in national average yield will add or subtract about 82 million bushels of corn or 89 million bushels of soybeans from total domestic production. The USDA releases the September WASDE on Wednesday (September 12). Continue reading at Tennessee Market Highlights.
