Set yield goals appropriately and feed plants to help achieve your highest yield goals. During the growing season, the NutriSolutions 360 system allows you to pinpoint your crop's nutritional needs and treat deficiencies before yield potential is compromised.
The nutrient amounts needed to produce 150 to 500 bushels of corn per acre from a typical crop are listed to the right. Nutrient requirements to produce 40 tons of corn silage per acre are similar to those for 300 bushels of corn.
CROPLAN® seed’s proprietary response to nitrogen (RTN) ratings range from 1 to 9. A high RTN score (7 to 9) identifies a hybrid that has an increased chance of return on investment from additional nitrogen (N) inputs or managing N for later release or in-season N applications. A medium RTN score (4 to 6) defines a hybrid as able to achieve high yields at moderate to higher N levels, yet still maintain yield in situations where N may be less than optimal. A low RTN score (1 to 3) indicates a hybrid with an acceptable yield potential even in situations where N may be limited. The charts below show how hybrids perform differently under different nitrogen management levels.
The relationship between RTN and RTP scores plays an important role in hybrid performance. This chart shows the correlation between hybrids that require incremental nitrogen when plant density is increased and hybrids where moderate to low yield response to nitrogen is observed with increased population.
All CROPLAN® corn is treated with Advanced Coating® Zn seed treatment. By coating seeds with zinc, Advanced Coating® Zn promotes quick emergence, even in cool, wet conditions, and it helps establish strong, healthy stands.
In nearly 180 Answer Plot® Program test plots over three years, corn treated with Advanced Coating® Zn seed treatment:
While Advanced Coating® Zn seed treatment provides early-season benefits for corn growth, it should not replace existing zinc programs. Additional zinc should still be used in starter fertilizer applications to promote normal corn plant growth and development in zinc-deficient soils.
Ascend® plant growth regulators set up corn for success from the first stage of growth. These photos show the application of Ascend® PGR with 10-34-0 plus zinc in-furrow vs. seed treated with 10-34-0 plus zinc only.
Using Ascend® plant growth regulators in-furrow has translated into an average yield response of 4.9 bushels per acre over five years of Answer Plot® Program trials.
