Nitrogen fertilizer rate affects root exudation, the rhizosphere microbiome and nitrogen-use-efficiency of maize

Rhizosphere Microbiome Modulators: Contributions of Nitrogen Fixing

9 Rhizosphere microbiomes which have been implicated to enhance plant growth and yield are 10 modulated or influenced by a couple of environmental factors such as soil type, plant cultivar, 11 climate change and anthropogenic activities. In particular, anthropogenic activity such as the use 12 of nitrogen-based chemical fertilizers is associated with environmental destruction and this call 13 f...

Investigation of Rate and Method of Nitrogen Application on Nitrogen Use Efficiency and Seed Yield of Safflower (Carthamus tinctorius L.)

Nitrogen fertilizer management has a special priority for safflower economic production. Increasing the efficiency of this element, in addition to increasing economic benefits, also reduces environmental pollution. Therefore, a factorial experiment was conducted in the form of statistical design of complete randomized blocks with three replications at Safiabad Agricultural and Natural Resources...

Glyphosate Affects Soybean Root Exudation and Rhizosphere Microorganisms

Nitrogen Dynamics and Fertilizer Use Efficiency in Rice Using the Nitrogen-15 Isotope Techniques

Nitrogen-15 ( N)-labeled biogas slurry (digested anaerobic organic residues (DAOR)) and chemical 15 fertilizer (CF) were applied to soil with low fertility cropped with rice. The N dilution method was used to 15 estimate the N uptake and recovery; potted soil was labeled with 1.0 atom % excess [ N] ammonium chloride 15 NH Cl. Certain select soil characteristics were also measured in soil amende...

Yield and nitrogen leaching in maize field under different nitrogen rates and partial root drying irrigation

Irrigation water is limiting for crop production in arid and semi-arid areas. Furthermore, excess nitrogen (N) application is a source of groundwater contamination. Partial root drying irrigation (PRD) can be used as water saving technique and a controlling measure of groundwater N contamination. The objectives of this investigation were to evaluate the effect of ordinary furrow irrigation (OFI...
