To the North West horticulturist there is no
problem which confronts him of so great moment as that
of soil fertility; and. no phase of horticulture is
more deserving of the attention of fruit growers, than
is given at the present time to the growing of orchard.
cover crops.
Irrigation should be recognized as agricultural art of
very wide applicability and value. Its association with the
idea of desert reclamation has blinded the public mind to its
value in reginos where there is no need of reclamation. It is
a means of soil improvement to be employed, like other...
The object of this work was to determine, as far as
possible, the germinating ability of pollen of different
varieties of fruit. The work was started with the idea
of making these determinations for both apples and pears but owing to lack of time and probably because the proper culture...
This investigation was undertaken to determine, from a dietetic
standpoint, the amounts and proportions of dextrose, levulose and
sucrose present in Bosc pears, and to furnish information that might
be of value in the development of by-products from the off-grade
fruit of this variety.
The attempt was made to carry...
Prune growers of Oregon are faced with the prospect
of large crops and surpluses for the next few years. These
surpluses will probably be felt in both fresh and dried prunes.
This thesis presents the results of an investigation to find.
new markets and new products which will be of...
This paper records a series of experiments conducted furing a one-year period to determine the effects of boron upon the growth and fruiting of Marshall and Corvallis strawberries, two of the leading commercial varieties in Oregon. The problem was approached in four ways: (1) applications of dry borax and borax...
A study has been made of the interrelations between certain of the physical and biochemical changes in three varieties of pears during storage and ripening. The metabolic changes which occurred in the fruit during cold temperature storage were found to influence with development of certain characteristics associated with dessert quality...
A regional analysis of the street tree problem has been undertaken in order to evolve a system of tree classification
which would be useful to city planners, arborists, and landscape architects who have the responsibility of selecting trees to fulfill their design requirements for the city street. Three lines of...
Progenies of two bean crosses were studied for inheritance of resistance to dry root rot caused by Fusarium solani f. phaseoli. O.S.C. 22 (P. vulgaris) was used in both crosses as the susceptible parent. A Mexican line (P. vulgaris) and a line 2014 of the runner bean (P. coccineus) were...
The nutrient elements needed for the optimum
growth and yield of pear trees is vitally important to the
pear growers. The knowledge of the amounts and kinds of
fertilizer to apply to obtain this growth could increase
the production and cut the costs for these growers.
Field experiments have been...
Much of the research effort with Dacthal in 1961 was based on obtaining samples for residue analysis. Crops in these tests included broccoli, cabbage, cauliflower, onions and soybeans. Observations were made on crop response and weed control.
Several herbicides were evaluated for selective weed control in sweet corn in 1961. Various methods of application were compared and a comparison of planting depths was made to determine possible interactive effects with Eptam applications
A planting of three varieties of strawberries was made in the spring of 1959 with herbicide treatments designed to provide weed control through the normal life of the planting.
In herbicide plots on tree fruits in the Willamette Valley and at Hood River there has been a consistent correlation between weed control effectiveness and tree growth in young orchards. This appears to be particularly true of weed control during the spring and summer obtained from spring applications as compared...
