Some effects of sulfur fertilization on the nutrient value of subclover-grass forage

Creator:

McCarthy, Michael J.

Abstract:

Pastures consisting of mixtures of subclover (Trifolium subterraneum) and grasses have responded to sulfur fertilization on many sites in Douglas County, Oregon. The objectives of this study were to examine specific changes in forage quality which occur as sulfur is applied in excess of the amount required for maximum yield...

Leaf elongation as a function of soil water potential and photoperiod

Creator:

Hodges, T.

Abstract:

Leaf elongation is a major indicator of plant growth. It is controlled by complex interactions of many factors including light intensity, photoperiod, water availability, atmospheric conditions, and plant water stress. In this study, the response of leaf elongation to length of photoperiod and to plant water stress as indicated by...
