Maize Morphophysiological Responses to Intense Crowding and Low Nitrogen Availability: An Analysis and Review
Mounting concerns over the cost and environmental impact of N fertilizer combined with progressively higher plant densities in maize (Zea mays L.) production systems make progress in maize N useExpand

Cover Crop Effects on Nitrogen Availability to Corn following Wheat
Maximizing the environmental and economic benefits of cover crops partially depends on an accurate estimate of the N fertilizer requirement of subsequent crops. Four trials involving cover crop,Expand

Physiological perspectives of changes over time in maize yield dependency on nitrogen uptake and associated nitrogen efficiencies: A review
Abstract Over the past 3 decades, the study of various mechanisms involved in maize grain yield (GY) formation and its relationship with nitrogen (N) uptake dynamics has been increasinglyExpand

A comprehensive study of plant density consequences on nitrogen uptake dynamics of maize plants from vegetative to reproductive stages
Abstract Nitrogen (N) use efficiency (NUE), defined as grain produced per unit of fertilizer N applied, is difficult to predict for specific maize ( Zea mays L.) genotypes and environments because ofExpand

Soil carbon and nitrogen accumulation with long-term no-till versus moldboard plowing overestimated with tilled-zone sampling depths
Numerous investigators of tillage system impacts on soil organic carbon (OC) or total nitrogen (N) have limited their soil sampling to depths either at or just below the deepest tillage treatment inExpand

Soil carbon dioxide and methane fluxes from long-term tillage systems in continuous corn and corn–soybean rotations
Abstract Although the Midwestern United States is one of the world's major agricultural production areas, few studies have assessed the effects of the region's predominant tillage and rotationExpand

Soil nitrate accumulation and corn response to preceding small-grain fertilization and cover crops
Potential benefits associated with establishing cover crops, such as reduced NO 3 leaching risk and lower fertilizer N requirements for succeeding crops, will he fully realized only when the coverExpand

Corn Response to Rye Cover Crop Management and Spring Tillage Systems
The use of a winter rye (Secale cereale L.) corn (Zea mays L.) doable cropping sequence in combination with appropriate tillage practices could increase biomass production and reduce soil erosionExpand

Nitrous oxide emissions in Midwest US maize production vary widely with band-injected N fertilizer rates, timing and nitrapyrin presence
Nitrification inhibitors have the potential to reduce N2O emissions from maize fields, but optimal results may depend on deployment of integrated N fertilizer management systems that increase yieldsExpand
