Assessing Freeze Damage in Wheat

Three major factors are when assessing freeze damage in winter wheat: growth stage, plant part temperatures and the duration of freezing temperatures. The plant is much more susceptible to damage when the head and growing point are above the soil surface. Definitive signs of damage appear three to seven days after the weather event…Read more

P and K Effect on Corn Yield

Phosphorous (P) and potassium (K) are critical nutrients for corn growth. Pioneer research shows that when P soil levels were low, plants showed no symptoms of P deficiency and showed no yield response to added P. However, when K levels where low, there was a significant yield response to applied K…Read more

Seed Orientation Effects on Grain and Silage Yield

Corn seeds that are planted with the tip downward emerge faster than seeds planted at other orientations. With kernels planted tip down, the first leaves of the corn plant generally emerge parallel to the germ. Pioneer researchers measured corn grain and silage yield with corn planted conventionally versus seeds planted manually to point downward. Averaged across the germ directions, seeds planted tip downward had up to 22% greater grain and silage yield and potential milk production per acre…Read more
