10 REPORT ON EXPERIMENT STATIONS, 1952
Since cotton must be cultivated repeatedly during the growing season,
this new spray rig attachment on the cultivator eliminates special
trips over the field for spraying. Mixing the insecticides and filling
the spray tank are the only additional operations necessary, but they
require only a few minutes. The rig can be attached or detacheid
quickly from the cultivator.
High-clearance mule-drawn cotton sprayer
The Tennessee station developed a cotton sprayer for use on a twowheeled,
high-clearance, mule-drawn cart. Its advantage lies in the
fact that it has a higher clearance and thus does less damage to large
cotton plants than tractor-mounted sprayers. It can be used in muddy
fields to maintain a spray schedule. Being mule-drawn it releases a
tractor for other farming operations during the busy crop season.
Although specially adapted to cotton spraying, it can also be used to
spray other crops. The unit can be assembled in the ordinary farm
shop and its low cost makes it practical for small growers. It consists
essentially of the cart, a spray kit which includes a low pressure pump,
low-volume nozzles, hoses, valves, boom, pressure gage and line
strainer, a 30-gallon oil drum, and a 1-horsepower air-cooled engine.
Mechanical stripping of sugar-beet leaves
A self-propelled, tricycle-type machine for removing the leafy
portion of sugar beet tops has been developed by the Colorado station.
The machine was devised as a result of studies showing that leaves
of sugar beets contain the major portion of the carotene and protein
of the whole tops. The leaves also contain less moisture than stems
and crowns and would be easier to dehydrate than the complete top.
Research feeding trials are under way to determine the value of this
material for livestock.
The machine has an operating width of four rows. Its dagger-like
knives mounted on revolving drums comb through the beet tops and
strip off the leaves. The machine operates most efficiently at a speed
of about 21/2 miles per hour.
A hinged elevator lifts the leaves to a truck or trailer driven alongside
the rows that can be quickly folded back over the stripper for
convenience to store it or to move it between fields. Normally about
70 percent of the leafy material is recovered, and the remainder of the
beet top can be utilized as pasture or silage. The harvesting capacity
of the machine in fields of exceptionally heavy tops is about 71/2 tons
Minimizing bruising in potato harvesting
The emphasis in potato harvesting today is on machinery that will
dig and sack a greater quantity of potatoes without bruising them.
Although some injuries occur in transit to distant markets, much of
the damage to potatoes comes through the use of poor handling
methods at harvest. After carefully studying the problem of potato
injury caused by mechanical harvesting, sorting, and grading, and
taking fully into consideration principles previously developed by the
Pennsylvania and other experiment stations in studies of the same
general problem under different conditions, the Idaho station developed
a, new separating mechanism that removes the dirt from
