An experiment was conducted to determine the best method to
establish subterranean clover on medusahead infested ranges in
Western Oregon. Secondary objectives of this study were to determind
the effects of management treatments on (a) subterranean
clover density, (b) density of medusahead and other vegetation, and
(c) yield of subterranean...
Field studies designed to study residual effects from fertilizer
molybdenum were initiated in September 1971 on established grass-clover
pastures at ten sites in Western Oregon. Treatments were 0.0
and 1.12 kg molybdenum /ha on plots receiving 0-35-0-20S fertilizer (elemental sulfur-S) and 0.0, 0.56, 1.12 and 2.24 kg molybdenum /ha on...

A seed maturation study was conducted to determine the earliest
date seed of subterranean clover (Trifolium subterraneum L.) may be
safely harvested without reduction in yield or seed quality. In 1981
and 1982, seed and bur weight, seed and bur moisture content, germination and seedling vigor were studied to determine...
In a series of greenhouse experiments, isolates representing serotypically
distinct subpopulations of Rhizobium leguminosarum bv. trifolii recovered from root
nodules of field-grown subclover Trifolium subterraneum cv. "Nangeela"), were
evaluated for their symbiotic effectiveness potential, their effect on regrowth
potential of subclover, and for their competitive abilities to form nodules. Isolates...
