About this file
This document is a Statement of Work (SOW) for a federal contract opportunity to provide corn isolated crossing blocks and a breeding nursery. The USDA's Agricultural Research Service (ARS) Germplasm Enhancement of Maize (GEM) Project requires eight corn isolated crossing blocks and two hand-pollinated corn breeding nurseries to be grown between April and November 2024 in central Illinois or Iowa.
The contractor must provide land, field preparation, fertilization, weed/pest control, and harvesting services. The government will provide the female seed packets. The contractor must monitor male rows, detassel female rows, and harvest and ship the resulting seed back to the USDA in Ames, Iowa and Raleigh, North Carolina. The period of performance is April 20, 2024 through November 30, 2024. This is a Lowest Price Technically Acceptable (LPTA) procurement, with quotes due by April 19, 2024. The associated NAICS code is 111150 (Corn Farming) with a $2.5 million small business size standard.

Statement of Work (SOW) Project: Corn Isolated Crossing Blocks and Breeding Nursery
GENERAL INFORMATION
1.0 Scope of Work: The USDA, ARS Germplasm Enhancement of Maize (GEM) Project of the Plant Introduction Research Unit (PIRU) has a requirement for eight corn isolated crossing blocks for production of topcross (hybrid) seed and two hand pollinated corn breeding nurseries for growing between April 20, 2024, and November 2024.
2.0 Background: Subject to local weather, soil moisture conditions, minimal disease, and low insect pressure, a central corn belt location is required. Central Illinois and central Iowa have been determined to be locations best suited for the requirement for the isolated crossing blocks and hand pollinated nursery planting required for this research. All isolations and nurseries shall be grown within a 6-month period beginning April 20, 2024, to be harvested and returned in approximately November 2024.
CONTRACTOR REQUIREMENTS
3.0 Technical Requirements/Tasks: Tasks and requirements that the contractor must provide are as listed below.
o Contractor will provide all field activities including Land for six isolated crossing fields Land for a hand pollinated corn breeding nursery Land located in either central Illinois or central Iowa Land preparation (tillage) Fertilization Weed and pest control Harvest o Field Isolation Requirements
Minimum of 500 feet separation of each isolation from other corn.
Female rows planted in 12-foot plot rows with 20-24 kernels per row.
Detassel female plot rows prior to pollen shed.
Isolated field to accommodate numbers of female entries as listed below.
- Isolation 1: 650 female rows
- Isolation 2: 1,000 female rows
- Isolation 3: 400 female rows
- Isolation 4: 800 female rows
- Isolation 5: 1,096 female rows
- Isolation 6: 1,280 female rows
Male:Female Planting Pattern and Delays
- Male:Female planting pattern of 6:4 for Isolation 1
- Male:Female planting pattern of 4:4 for all other Isolations
- First male row planted 100-150 growing degree units (GDU) before female entries are planted
- Second and third male rows planted at same time as female entries
- Fourth male row planted 100-150 GDU after females are planted
- Monitor male rows for off-type plants and remove before pollen shed
- Isolation crossing field must be bordered on each side by 4 rows of male

o Shipping to:
USDA-ARS-NCRPIS, 1305 State Ave., Ames, IA 50014 for GEM-Ames generated materials.
USDA-ARS, 13223 US Business 70 West, Clayton, NC 27520-2128 for

5.0 Deliverables / Schedule:
o Fields to be planted as close to April 20, 2024 as conditions allow and no later than June 10, 2023.
o Written report of project status, crop development, and field condition for each isolation sent to adam.vanous@usda.gov every 2 weeks after planting.
