Recent Research Projects

Project:   Male sterility and xenia effects on corn hybrid performance

Locations:   four sites - Western Agricultural Research Station, Northwestern Agricultural Research Station, West Badger Research Farm (Apple Creek) and Van Wert

Project Investigators: Peter Thomison, Allen Geyer, and Richard   Minyo, Jr.

Description:   The objective of this study was to compare the agronomic performance of 100% male sterile corn hybrids and their 50% and 100% fertile counterparts across a range of production environments.   Project ended in 2003.

Project:   Differential canopy defoliation effects on yield and stalk quality of corn

Locations:   two sites - Western Agricultural Research Station, Northwestern Agricultural Research Station

Project Investigators:   Peter Thomison and Allen Geyer

Description:   The objective of this study was to determine differential defoliation effects on the agronomic performance of two corn hybrids with different canopy architecture (varying in maturity, height, and leaf orientation). Defoliation treatments, which simulate leaf damage from hail, disease, or drought, involved    50 or 100% leaf removal, above or below the ear leaf, and an untreated check.   Defoliation treatments were imposed at the silk, blister, milk, and dough stages of kernel development.   Project ended in 2002.

Project:   Nitrogen rate and timing effects on nutritionally enhanced corn hybrids

Location:    Northwestern Agricultural Research Station

Project coordinator:   Peter Thomison

Description: The objective of this study was to measure the impact of varying N rates and timings of N application on the grain yield, protein and oil composition of corn hybrids with nutritionally enhanced grain quality. Two hybrids containing Supercede genetics were evaluated at four levels of nitrogen (0, 60, 120, 180 lbs N/A) applied at planting and sidedressed. Project ended in 2002.

Project:   Evaluations of Nutritionally Enhanced Corn Hybrids.

Locations:    Northwestern Agricultural Research Station and Western Branch Research Station

Project Coordinator:   Peter Thomison

Description: The objective of this project was to compare the agronomic performance and grain quality (oil, protein, and starch content) of Nutridense and Supercede corn. Conventional corn hybrid checks were included as checks.   Project was conducted in 1999 and 2000.

Project:   White Food Grade Corn Test

Location:   Northwestern Agricultural Research Station

Project Coordinator: Peter Thomison

Description:   The objective of this testing program was to evaluate the agronomic performance of early maturity white food grade corns as part of a USDA regional project. Several popular yellow dent corn hybrids were grown as checks.    OSU participated in the program from 1996 to 2002.

Project:   Blue and Red Corn Evaluation

Locations :   Western Agricultural Research Station, Northwestern Agricultural Station, Wooster

Project Coordinator:   Peter Thomison

Description:   The objective of this study was to evaluate agronomic performance of blue and red food grade corns, both hybrids and open-pollinated varieties. A popular yellow dent corn hybrid was grown as a check.   Project ended in 2002.

Project:   Specialty Corn Performance Test

Locations:   Columbus, Western Agricultural Research Station, Northwest Agricultural Research Station, Wooster

Project Coordinator:   Peter Thomison

Description:   The objective of this study was to compare the agronomic performance of various specialty corns.   Specialty corns included Nutridense, high extractable starch, waxy, high lysine, yellow food grade, TopCross high oil, white food grade, and Supercede. A popular conventional corn hybrid was grown as a check.   Project ended in 2001.

Project:   Roundup Ready Corn Hybrid Evaluation

Locations:   Western Agricultural Research Station

Project Coordinator:   Peter Thomison

Description:   The objective of this study was to compare the agronomic performance of Roundup Ready and conventional non-Roundup tolerant corn hybrids as part of a multi-state study.   Project was conducted in 1999 and 2001.

Project:   Defoliation Effects on High Oil Corn Production

Locations:   Western Agricultural Research Station, Columbus Waterman Farm, Wooster Schaffter Farm, and Farm Science Review

Project Investigators: Peter Thomison, Allen Geyer, and Todd Mangen

Description:   The objectives of this study were to compare effects of defoliation on the agronomic performance and grain quality of a high oil corn TC Blends with its normal oil counterpart, and to determine if the two components of a TC Blend differ in their responses to defoliation. The high oil blends were subjected to defoliation during the vegetative, reproductive, and grain fill stages.   Project ended in 2000.

Project:   TopCross High Oil Corn Performance Test

Locations:   Western Agricultural Research Station and Northwestern Agricultural Research Station.

Project Coordinator: Peter Thomison

Description:   The objective of this study was to compare the agronomic performance and grain quality of commercially available TopCross high oil corn hybrids. The conventional hybrid counterparts of three of the high oil blends were grown as checks.    Project ended in 2000

Project:   The Role of Ear Type in Corn Interactions with Management and Environmental Factors (Hatch -117)

Locations:   Western Agricultural Research Station and Northwestern Agricultural Research Station.

Project Coordinator:   Peter Thomison

Description: The objective of this study was to determine the role of corn ear type in hybrid response to varying production environments. Effects of various seeding rates, nitrogen rates, and planting dates on hybrids with different ear types have been investigated across a range of production environments.
