Soil compaction and erosion are problems in many Pacific Northwestern potato fields. We wanted to determine if zone-subsoiling would reduce these problems and improve potato yields and or grade without adversely impacting other production practices.

A device and procedure have been developed for measuring tuber skin strength of Russet Burbank potatoes. Tests were designed to quantitatively measure the effects of: 1) various vine killing methods, 2) elapsed time between digging and testing, 3) te

Studies in southeastern Idaho evaluated the potential of tillage under the potato row (zoned tillage) to influence tuber yield and grade. Such tillage is estimated to provide significant improvement in control of water erosion. The ‘Russet Burbank

Potato seed pieces were hand planted with different spacings in the row and percentages of doubles to determine the effects on total yield and tuber size distribution. The objective was to determine acceptable performance levels for commercial potato

The performance of the vibrating blade, attached to a two-wheeled and hand-steered 7.35 kw tractor, was improved by increasing frequency while reducing amplitude. Increased frequency assisted the travel speed of the machine by better feeding of mater

The relationship of potato (cv. Russet Burbank) tuber stem-end discoloration to speed of vine kill and maturity of vines when killed was studied for three years at several sites in Idaho. Discoloration due to leafroll was separately determined. Vine

REASONS for quality loss in farm-stored wheat and barley were studied for three years. Paired bins at several sites were instrumented to determine internal conditions. Grain samples were taken at ten-day intervals to determine moisture content, insec

FOUR commercial row crop planter units were evaluated for their seed metering ability in selecting single edible bean seed and how the seed was spaced in the furrow. Five varieties of ungraded edible beans were used for evaluation. None of the units
