Crop scouting reports

Crop scouting is an essential part of integrated pest management (IPM). Scouting programs are designed to protect and maximize crop yield and quality while minimizing the risk associated with pesticide use. 

Each week, an extension agronomy specialist scouts fields in Barton County and then report their findings through an automated phone service and email message. The message will go out to everyone signed up for the program.

The weekly field scouting report is sponsored by University of Missouri Extension and Barton County Extension.  To receive the 2015 weekly scouting reports, print the 2015 Crop Scouting Enrollment Form, complete and return with payment to Barton County Extension, 801 E 12th, Lamar, MO 64759 or contact the MU Extension Center in Barton County, 417-682-3579.

The cost of the program is only $35 per phone number, $95 for three numbers and $30 per phone number for those with four or more.

Current weekly report

October 21 - Estimating soybean yield possible with basic formula

PDF      Audio

Jill Scheidt, agronomy specialist with University of Missouri Extension, scouted fields near Arcola in Dade County and north of Willard in Greene County on Oct. 21.

Soybean Report
In the fields scouted, Scheidt observed soybeans in full seed and beginning to turn color to full maturity stage. “Harvest soybeans at 13 percent moisture,” said Scheidt.

To estimate soybean yield, sample at least eight areas in each field to have the most accuracy. Errors in yield estimate are likely to be 20 percent, so the more areas sampled the better chance of a correct yield estimate according to Scheidt.

“To estimate soybean yield, determine the plant population per acre by measuring 1/1000th of an acre. This distance will vary depending on row spacing,” said Scheidt.

For example: 30 inch rows equals 17 feet 5 inches, 15 inch rows equals 34 feet 10 inches, and 7.5 inch rows equals 69 feet 8 inches.

Calculation is fairly simple according to Scheidt.

Formula: (Plants per acre) X (pods per plant) X (seeds per pod) / (seeds per pound) / (pounds per bushel) = (bushels per acre).

Example: (150,000) X (20) X (2.5) / 3000 = 2500 then: 2500/60 = 41.6 or 42 bushels per acre.

The weekly field scouting report is sponsored by University of Missouri and Barton County Extension. For more information on the scouting report, or to learn how to receive the information earlier by telephone, contact the Barton County Extension Center at (417) 682-3579.
