No-till Wheat Production in Oklahoma
نویسندگان
چکیده
Should I switch from conventional till to no-till wheat production? This is one of the most common questions asked by Oklahoma farmers, but it is also one of the most difficult to answer. There are several considerations when making this decision, and there is certainly no one-size-fits-all program for converting from conventional till to no-till wheat production. A few factors to be considered include management intensity, ability to include rotational crops, importance of soil conservation, labor availability and cost, equipment upgrade needs and fuel cost. Because of the need to change agronomic practices to meet changing environmental situations, the managerial requirements of a no-till wheat production system are generally greater than that of a conventional till system.

Perceptions on the use of no-till farming in production agriculture in the United States: an analysis of survey results
A number of economic and environmental benefits are associated with the use of no-till in production agriculture in the United States. There are lower labor, energy, and machinery costs associated with no-till farming relative to conventional tillage systems and other types of conservation tillage. Reduced erosion and runoff associated with no-till also lead to a number of environmental benefit...
متن کاملComparison of Runoff, Soil Erosion, and Winter Wheat Yields from No-Till and Inversion Tillage Production Systems in Northeastern Oregon
Conservation tillage systems that reduce soil erosion and maintain or increase soil carbon offer long-term benefits for producers in the inland Pacific Northwestern United States but could result in reduced grain yields due to increased pressure from weeds, disease, and insect pests. Our objective was to compare runoff, soil erosion, and crop yields from a conventional tillage, wheat-fallow two...
متن کاملAdaptability of Wheat Cultivars to a Late-Planted No-Till Fallow Production System
In Washington, over fifty percent of the wheat produced under rainfed conditions receives less than 300 mm of annual precipitation. Hence, a winter wheat-summer fallow cropping system has been adopted to obtain adequate moisture for winter wheat production. Current tilled fallow systems are exposed to significant soil degradation from wind and water erosion. As a result, late-planted no-till fa...
متن کاملWheat Cultivar Performance and Stability between No-Till and Conventional Tillage Systems in the Pacific Northwest of the United States
In Washington, over fifty percent of the wheat produced under rainfed conditions receives less than 300 mm of annual precipitation. Hence, a winter wheat-summer fallow cropping system has been established to obtain adequate moisture for winter wheat production. Current tilled fallow systems receive significant soil erosion through both wind and water. As a result, no-till chemical fallow system...
متن کاملNitrogen Fertility and Weed Management Critical for Continuous No-Till Wheat in the Pacific Northwest1
No-till cropping is an option for growers needing to reduce soil erosion in the Palouse annual-cropped region of the Pacific Northwest, which is well suited for wheat production. A 6-yr field study was conducted to determine optimum levels of fertilizer and herbicide inputs in a no-till continuous wheat crop production system. Three levels of nitrogen (N) and two weed management levels (WML) we...
