Three deep experimental filters were used to evaluate the influence
of the physical factors of media size, depth of filter, and organic and hydraulic loading on contact time and the rate of removal
of organic material by the biological growth on the filters. A
further correlation was made between contact...
The objectives of these experiments were to determine
the feasibility of saving seed from snap bean fields in the
Willamette Valley that have been bypassed for canning and
freezing, and to study the effects of different seed production
methods on yield and quality of snap bean (Phaseolus
vulgaris L.).

The objective of this study was to develop a soaking and drying
procedure to stimulate faster germination of Kentucky bluegrass (Poa
pratensis L.) seed.
The seeds were soaked in cheesecloth bags in nine chemical
solutions. The effects of temperature and time of soaking and of
aeration of the solution were...
The objective of this research was to identify the
optimum cultural practices for the production of the highest
quality wheat seed in Oregon. The production methods
included locations, irrigation, N levels and seeding rates.
The seed quality factors studied were seed weight, bushel
weight, protein content and seedling vigor.
Foundation...
One of the major items in any program of municipal sanitation is the double problem of water supply and waste water disposal. Since streams are the general source of water supply and also the final receptacle for sewage, this dual use of the stream often leads to complications. Sewage and...
The purpose of this study was to evaluate the effect of seed
protein content on plant growth of barley (Hordeum vulgare L. )
and wheat (Triticum aestivum L. ). The effects of nitrogen application
on chemical and morphological characteristics of the seed
were also studied.
Seeds of 'Casbon' winter barley...
