Nitrogen fertilizer and tillage intensity affected winter wheat macronutrient uptake and utilization efficiencies

چکیده
Application of N fertilizer and no-tillage (NT) can increase winter wheat (Triticum aestivum L) production through improvements in plant available soil water nutrient availability. However, long-term tillage management interaction effects on uptake are not well known. The objective this study was to quantify grain yield, macronutrient removal, utilization responses application intensity. conducted 2019 2020 at Hays, Kansas after 45 years fertility experiment. Treatments were a combination two practices (CT, conventional tillage; NT) four rates (0, 45, 90, 134 kg ha−1). Results showed significant effect removal (NR) (grain-N, -P, -K, -Mg; stover-K, total P), concentration (stover-K -S). Two different quadratic models fit the rate-to-yield relation for CT NT with yields 4.3 5.2 Mg ha−1 agronomic optimal 119 199 ha−1, respectively. This suggests that high enough predict optimum rate environment. With an average yield 3.30 removed about 113 17 P 56 K 7 Ca 8 S irrespective practice. Grain NR greater smaller (<90 ha−1) (>90 Findings suggest adequate should be maintained improve uptake, efficiency dryland systems.

Genetic differences for nitrogen uptake and nitrogen utilisation efficiencies in winter wheat
Due to economic and ecological factors, European agricultural practices are likely to go towards extensive systems with lower inputs of nitrogen (N) fertilisers. The objective of this study was to assess varietal differences for N use at two nitrogen levels. A set of 20 winter wheat (Triticum aesti6um L.) genotypes was studied over 2 years in northern France on a deep loam soil without (N0) and...

Disposal of poultry litter, a widely available organic manure in the southeastern USA because of a largescale poultry industry, is a major concern because of its contamination in surfaceand groundwater through N leaching and P runoff. Application of poultry litter in no-tilled intensive cropping system could increase soil C and N sequestration compared with the conventional-tilled system with i...

This study was carried out under temperate climate condition of Ilam province, Iran, during 2012-2013 growing season to determine the suitable crop rotation for enhancing nitrogen uptake, utilization, and use efficiency of wheat. A two factor experiment was laid out as split plot arrangement (RCBD) with four replications. The main plots consisted of 6 pre-sowing plant treatments (control, Perko...

Increased yields with conservation tillage have been attributed to the conservation of soil water (Rao and Sustainable cropping systems are essential for agronomic, ecoDao, 1996; Papendick and Miller, 1977) due to decreased nomic, and environmental reasons. Data from a winter wheat (Tritievaporation and cooler soil temperatures (Gauer et al., cum aestivum L.)/summer fallow rotation experiment, ...
