Creator:: Suttner, Donald Lee
Abstract:: Field studies to determine appropriate cutting management regimes consistent with yield, quality, and persistence of stand were conducted on several alfalfa varieties in the Columbia Basin region of Oregon. Two groups of treatments, including consecutive cuts at the same stage of maturity and cuts made at varying maturities, were imposed...

Full Text:: ABSTRACT OF THE THESIS OF DONALD LEE SUTTNER for the degree of DOCTOR OF PHILOSOPHY in Agronomic Crop

Creator:: Ott, Pablo
Abstract:: Volunteer winter wheat (Triticum aestivum 'Daws') severely suppressed growth of fall-planted alfalfa (Medicago sativa (L.) 'Vernal') seedlings. Wheat competition began soon after alfalfa emerged and continued until the first forage harvest the following May. Alfalfa yield at the first cutting was reduced by 1% for each day volunteer wheat was...

Creator:: Phillips, John Charles
Abstract:: Experiments were conducted to determine the effects of certain plant regulatory chemicals on seed production of alfalfa (Medicago sativa L.). Two plant regulators, SADH (succinic acid 2,2-dimethylhydrazide) and TIBA (2,3,5- triiodobenzoic acid), received particular attention. Replicated field tests of the plant regulators were carried out on the cultivar 'Talent' in...

Creator:: Shuler, Philip E.
Abstract:: The usefulness of preplant nitrogen (N) in establishing alfalfa in colder production areas has not been well characterized. This study was conducted to determine the effect of preplant N and soil temperature on yield, percent N derived from biological nitrogen fixation (PBNF), and shoot N concentration in alfalfa (Medicago sativa...

Creator:: Eardly, Bertrand D.
Abstract:: Nitrogen fertilization of seedling legumes is a controversial practice intended to provide N to the plant during periods when seed N, soil N, and N₂ fixation may not meet plant requirements; eg. prenodulation, postharvest, or in the event of an inoculation failure. Field experiments were conducted in 3 consecutive years...
