Nitrogen Management Of Winter Triticale, Lance R. Gibson, Carasella Nance, Douglas L. Karlen Jan 2006

Nitrogen Management Of Winter Triticale, Lance R. Gibson, Carasella Nance, Douglas L. Karlen

Iowa State Research Farm Progress Reports

Triticale (trit-ah-kay-lee) is a close relative of wheat. When durum wheat is pollinated with rye pollen, the cross is used in a breeding program to produce stable, self-replicating varieties. Triticale yield, stress tolerance, and disease resistance are typically greater than similar traits found in wheat. Triticale does not currently possess the grain traits of bread wheat, so its greatest market potential is as animal feed.

Soybean Yield Influenced By Planting Date And Plant Population, Palle Pedersen Jan 2006

Soybean Yield Influenced By Planting Date And Plant Population, Palle Pedersen

Iowa State Research Farm Progress Reports

Soybean yields often increase, up to a point, with increasing plant population. However, soybean yield responses to plant population are generally small and often inconsistent. In general, increasing plant populations increase plant height and result in greater yield losses from lodging. Soybean seed prices have increased tremendously over the last couple of years. Our hypothesis is that seed cost can be reduced in replanted fields. The objective of this experiment was to determine the optimum plant population across different planting dates in northeast Iowa.

Iowa State Research Farm Progress Reports

This project evaluated granular corn gluten meal (CGM) application rates and cultivar performance for day-neutral strawberry production in Iowa. CGM is a byproduct of the wet milling of corn. It provides 10% nitrogen by weight and can serve as a natural nitrogen product. Seascape is a newer day-neutral cultivar, and its adaptation to Iowa needs to be evaluated and compared with the standard Tristar and Tribute day-neutral strawberries.


Phosphorus And Potassium Management For Corn And Soybeans Managed With No-Till And Chisel Plow Tillage, Antonio P. Mallarino, Kevin Van Dee Jan 2006

Phosphorus And Potassium Management For Corn And Soybeans Managed With No-Till And Chisel Plow Tillage, Antonio P. Mallarino, Kevin Van Dee

Iowa State Research Farm Progress Reports

A study was initiated in 1994 to evaluate phosphorus (P) and potassium (K) fertilizer rates and placement methods for corn and soybeans managed with no-till and chisel plow tillage. No-till management resulted in little or no incorporation of residue and fertilizer into the soil. Broadcast fertilization has generally been inefficient with no-till because both nutrients accumulate near the soil surface. Subsurface banding of P and K fertilizers, however, can be more effective.
