In Winter Wheat, No-Till Increases Mycorrhizal Colonization thus Reducing the Need for Nitrogen Fertilization
Arbuscular mycorrhizal fungi (AMF) play a major role in the uptake of nutrients by agricultural plants. Nevertheless, some agricultural practices can interrupt fungal-plant signaling and thus impede the establishment of the mycorrhizal symbiosis. A field experiment performed over a 5-year period demonstrated that both the absence of tillage and of nitrogen (N) fertilization improved AMF coloniz...
متن کاملNitrogen Fertilization of Wheat No-Till Planted in Alfalfa Stubble
The N available after legumes is sufficient for maximum crop yields in many cropping systems. Fertilizing without accounting for the "extra" N mineralized from legume residues can contribute to high nitrate-N concentrations in the soil during crop production and increase nitrate-N leaching potential. Tillage practices also affect the physical, biological, and chemical nature of the soil, changi...

and Reule, 1994; Norwood, 2000; Peterson et al., 1993; Schlegel et al., 2002). No-till (NT) production systems, especially winter wheat (Triticum Dhuyvetter et al. (1996) reported that the more intenaestivum L.)–summer crop–fallow, have increased in the central Great sive cropping systems had higher profit potential than Plains, but few N fertility studies have been conducted with these systems...
متن کاملWinter Wheat Grain Yield and Grain Nitrogen as Influenced by Bed and Conventional Planting Systems
Bed planted wheat systems offer a new alternative for the traditional wheat producer to provide opportunities for crop rotation, more efficient use of water, and new techniques of nutrient management. This study was conducted to determine if planting winter wheat (Triticum aestivum L.) in Oklahoma on raised beds can maintain grain yields while providing more options in the cropping system. Expe...
متن کاملEight years of annual no-till cropping in Washington’s winter wheat-summer fallow region
The tillage-based winter wheat (Triticum aestivum L.)-summer fallow (WW-SF) cropping system has dominated dryland farming in the Pacific Northwest USA for 125 years. We conducted a large-scale multidisciplinary 8-year study of annual (i.e., no summer fallow) no-till cropping systems as an alternative to WW-SF. Soft white and hard white classes of winter and spring wheat, spring barley (Hordeum ...
