Nitrogen management impact on winter wheat grain yield and estimated plant nitrogen loss
(Agronomy Journal, 2020)
Method of N application in winter wheat (Triticum aestivum L.) and its impact on
estimated plant N loss has not been extensively evaluated. The effects of the pre-plant
N application method, topdress N application method, ...
No-tillage Improves Winter Wheat (Triticum Aestivum L.) Grain Nitrogen Use Efficiency
(Communications in Soil Science and Plant Analysis,, 2019)
Tillage practices are among the factors that affect soil quality as well as use
efficiency of fertilizer nitrogen (N). Data consisting of 24-site-years from two
long-term experiments 222 (E222) located in Stillwater and ...
Nitrogen Uptake Efficiency and Total Soil Nitrogen Accumulation in Long-Term Beef Manure and Inorganic Fertilizer Application
(International Journal of Agronomy, 2019)
Livestock manure is a common soil amendment for crop-livestock production systems. However, the efficiency of crop nitrogen
(N) uptake from the manure-amended soil may not equate with that from inorganic N sources. +e ...
Improving winter wheat grain yield and nitrogen use efficiency using nitrogen application time and rate
(Agrosystems, Geosciences & Environment, 2021)
Preplant nitrogen (N) application, which involves placing nutrients in the soil before
seeding, has been an integral part of crop production systems for decades. Some
producers are known to apply N at least 21 d before ...
Effect of Long-term Beef Manure Application on Soil Test Phosphorus, Organic Carbon and Winter Wheat Yield
(Journal of Plant Nutrition, 2017)
In this study, 24 years (1990-2013) of data from a long-term experiment, in Stillwater, Oklahoma (OK) were used to determine the effect of beef manure on soil test phosphorus (STP), soil organic carbon (SOC) and winter ...
Biochar Application in Combination with Inorganic Nitrogen Improves Maize Grain Yield, Nitrogen Uptake, and Use E ciency in Temperate Soils
(Agronomy, 2020)
Biochar (B) has shown promise in improving crop productivity. However, its interaction
with inorganic nitrogen (N) in temperate soils is not well-studied. The objective of this paper was
to compare the e ect of fertilizer ...
In-Season Application of Nitrogen and Sulfur in Winter Wheat
(Agrosystems, Geosciences & Environment,, 2019)
Decreased atmospheric S deposition in the past 20 yr has led to increased S fertilizer consumption
in winter wheat (Triticum aestivum L.). Producers often apply S without any soil test information.
Experiments were ...
World Cereal Nitrogen Use Efficiency Trends: Review and Current Knowledge
(Agrosystems, Geosciences & Environment, 2019)
Two decades ago, world cereal nitrogen use efficiency (NUE) was documented at 33%. Since then,
research addressing NUE has advanced. However, there are no current estimates to communicate
whether or not research efforts ...
Influence of No-Tillage on Soil Organic Carbon, Total Soil Nitrogen, and Winter Wheat (Triticum aestivum L.) Grain Yield
(International Journal of Agronomy, 2019)
No-tillage (NT) can improve soil properties and crop yield. However, there are contrasting reports on its benefits compared to conventional tillage (CT). Dataset (2003–2018) from long-term continuous winter wheat (Triticum ...
Variability in Winter Wheat (Triticum aestivum L.) Grain Yield Response to Nitrogen Fertilization in Long-Term Experiments
(Communications in Soil Science and Plant Analysis, 2020)
Crop nitrogen (N) use is always affected by the variability in production
environment. Dataset (2001 to 2014) from long-term winter wheat (Triticum
aestivum L.) experiments at Lahoma and Stillwater, Oklahoma was used.
Both ...
