1. Application of the Ceres-maize Model to Maximum Yield Research Maximum yields are obtained when as much assimilate as possible is partitioned into the grains of corn. The amount partitioned into the grains depends on several major factors. Grains per unit area is probably the most important of these factors. Other important considerations for grain filling in- clude the duration of the grain filling period, the amount that can be repartitioned from stem storage to the grains, the photo- synthesis rate, and the temperature. Several factors influence the number... Download paper
2. Nitrogen and Potassium Interactions in Corn Extensive research in the North Central region has investigated separately nitrogen (N) and potassium (K) fertilizer management for corn. However, there is scarce information available about how N and K interactions affect corn grain yield and nutrient uptake. The objective of this study was to evaluate the effects of various combinations of N and K rates on corn yield, N and K tissue concentrations, and N and K removed with grain harvest. Two trials with continuous corn were conducted from 2013... J. Hirniak, A. Mallarino Download paper
3. Can Kura Clover and Winter Rye Covers Mitigate Nitrate Leaching In Irrigated Sands? Cover crops are gaining more popularity as a mitigation tool to prevent nitrate (NO3--N) leaching from the corn (Zea mays L.) and soybean [Glycine max (L.) merr.] fields of Minnesota. Leaching of NO3--N is not only a monetary loss for growers, but also results in groundwater contamination. Winter rye (Secale cereale), a commonly grown cover crop in Minnesota and kura clover (Trifolium ambiguum), a less...
4. A Minnesota-Wide Assessment of Critical Pre-Plant and in-Season Soil Nitrate for Adjusting Nitrogen Rate Guidelines The pre-plant (PPNT) and pre-sidedress (PSNT) soil nitrate tests are often used as indicators of soil nitrogen (N) availability in Minnesota. The assessment of available soil nitrogen (N) provides corn (Zea mays L.) growers with key information on N credits to adjust their N fertilizer rates. However, current N management recommendations in Minnesota were based on research conducted 40-yr ago and did not specify differences between environments and management. Through a comprehensive...
