NITROGEN MANAGEMENT Nitrogen Fertilization and Rotation Effects on No-Till Dryland Wheat Production
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 کاملNitrogen Fertilizer Management in Dryland Wheat Cropping Systems
Wheat is the most widely cultivated food crop in the world, which provides nutrition to most of the world population and is well adapted to a wide range of environmental conditions. Timely and efficient rates of nitrogen (N) application are vital for increasing wheat grain yield and protein content, and maintaining environmental sustainability. The goal of this study was to investigate the effe...
متن کاملExpected Economic Potential of SubstitutingLegumes for Nitrogen in Bermudagrass Pastures
Grazing warm-season grass pastures with stocker cattle (Bos taurus) is an important economic activity in the southern Great Plains, and substantial increases in the price of N fertilizer have negatively affected profi tability of forage producers. The goal of the study was to determine if bermudagrass [Cynodon dactylon (L.) Pers.] pastures interseeded with either annual or perennial legumes are...
متن کاملOrganic Waste Nitrogen and Phosphorus Dynamics under Dryland Agroecosystems
Organic waste beneficial-use programs effectively recycle plant nutrients when applied at agronomic rates. Our objectives were to determine: biosolids nitrogen (N) fertilizer equivalency; biosolids N mineralization during years of above and below average precipitation and long-term N mineralization; which soil phosphorus (P) phases dominate following years of biosolids application; and the pote...
متن کاملManaging precipitation use in sustainable dryland agroecosystems
In the Great Plains of North America potential evaporation exceeds precipitation during most months of the year. About 75% of the annual precipitation is received from April through September, and is accompanied by high temperatures and low relative humidity. Dryland agriculture in the Great Plains has depended on wheat production in a wheat-fallow agroecosystem (one crop year followed by a fal...
