Traditionally, M. chitwoodi is controlled with
chemical nematicides, many of which risk
suspension for use on potatoes due to health and
environmental concerns. It is essential to develop
and refine alternative strategies for controlling
Columbia root-knot nematode now, so that
productive and profitable potato acreage will not
be lost if...

To disseminate update technologies and to enhance capabilities of resource poor farm families for the production of capture as well as culture fisheries, using natural and socio-economic resources an extensive study on linkage between resource availability and production potentiality were undertaken in the study area (under New Alluvial Zone of...
The use of management units for soil testing and nutrient application is an
effective strategy to increase accuracy in monitoring and managing nitrogen (N), phosphorus (P), and other nutrients. A management unit can be a group of fields, a single field, or an area within a field. To measure changes...
Survey In 1995, the Washington County Soil & Water Conservation District interviewed 90 farmers in northwest Oregon's Tualatin River Basin, using a survey developed by the USDA - Natural Resources Conservation Service (NRCS) and Oregon State University (OSU) Extension Service. Crop rotations, yields, tillage, fertilizer and irrigation practices were recorded....
A system of quasilinear degenerate parabolic equations arising in the modeling of diffusion in a fissured medium is studied. There is one such equation in the local cell coordinates at each point of the medium, and these are coupled through a similar equation in the global coordinates. It is shown...
