t goes without saying that variety/hybrid selection is one of the most important decisions that a rice farmer has to make during the winter planning time. Following are quite a few offerings for 2015. Consider your farm field-by-field when making choices for the upcoming season. The following information about these rice varieties/hybrids and their characteristics was provided by Horizon Ag, LLC and RiceTec. The charts were provided by Horizon Ag.

1 Height will vary with plant density and environmental conditions.

2 Maturity varies with geographical region and environmental conditions in a given year.

3 Optimal seeding rate varies depending on soil characteristics, seedbed condition and environmental conditions at time of planting.

4 Optimal nitrogen rate varies from field to field. The high end should be reserved for heavy clay soils and fields where rice is followed by rice. Using the high end of the nitrogen and seeding rate recommendations may increase the incidence of disease.

Please scout and treat the Clearfield varieties accordingly. The NSt*R program is recommended where applicable and has been shown to decrease incidence of disease and lodging. Please contact your local Cooperative Extension office for more information.

For Best Variety Performance: Clearfield varieties have excellent vigor and tolerate full rates of Newpath even in cool, wet conditions. To optimize returns on your farm, it is Horizon Ag’s recommendation to plant Clearfield varieties in the earliest part of the planting window for the given location and year.

Implement Horizon’s “Premium Seed Treatment” recommendation by using the manufacturers’ recommended minimum rate of Release or an equivalent gibberellic acid (GA3) plant growth regulator, plus labeled rates of the following rice fungicide and insecticide products: • CruiserMaxx Rice • Or combinations of Maxim plus Apron and Dermacor or NipsIt INSIDE
