Field Cropping Semi-Arid

Titre : DEVELOPING SUSTAINABLE FIELD CROPPING SYSTEMS IN SEMI-ARID EASTERN OREGON

Identification : ORE00109

Pays : Etats Unis

Durée : Oct 1, 2002 à Sep 30, 2007

Domaine : Plant Biological Efficiency and Abiotic Stresses Affecting Plants ; Plant Management Systems ; - Basic Plant Biology ; Wheat, general ; Peas (dry)

Partenaire : OREGON STATE UNIVERSITY CORVALLIS,OR 97331

Objectifs
Objective 1 (Long-term experiments) : To establish a series of long-term experiments that will compare the effects of conventional crop rotations and crop management practices with potential alternative crop rotations and crop management practices such as direct seeding. Objective 2 (Alternate Rotational Crops) : To obtain alternate crop seed from areas with similar climate to eastern Oregon and from breeders at OSU, WSU, and UI ; to evaluate the adaptability of alternate crops to growing conditions in eastern Oregon ; and to establish basic agronomic practices of commercially promising alternate crops under reduced tillage systems. Objective 3 : (Site-specific farming) To identify biotic and abiotic factors that influence the spatial and temporal variability in crop yields in farmers fields and to use this information to increase crop production efficiency by applying inputs based on the requirements of specific areas in a field. Objective 4 (Drought and High Temperature Studies) : To obtain different wheat varieties or lines from the OSU breeding program and other regions of the world with similar climate to eastern Oregon and screen them for the stay-green character ; to determine whether the stay-green character improves grain filling and quality, and to make available the lines or varieties expressing this trait to the OSU breeding program for improving drought and heat tolerance in wheat. Work will also be conducted to determine mechanisms of drought and heat tolerance and to determine whether drought and heat tolerance improves resistance to diseases particularly Fusarium root rot that is prevalent in eastern Oregon.
