Three different ground cover management strategies were compared at the OSU research vineyard near Alpine, Oregon. Botanical diversity was actively increased in two diverse treatments. Another treatment was botanically uniform and contained creeping bentgrass (Agrostis stolonifera). The composition of the vineyard floor vegetation and grapevine performance as affected by the...
Three different cover crop treatments were compared for their effects on vine growth, leaf gas exchange, yield parameters and fruit composition. The treatments were: resident plants, an insectary plant mixture and a grass cover. At veraison (August 2 1), photosynthesis rate was lowest for the vines with the grass cover...
Soil and vineyard vegetation management are tools that may be used to create stable growing conditions for the grapevine roots and to preserve soil fertility for high grape quality in future years. The use of cover crops is commonly practiced in viticultural areas where precipitation exceeds 600-700 min (24-28 in)...
Increasing ecological awareness led to the conceptualization and implementation of sustainable production systems such as Integrated Production. Integrated Production (IP) aims at achieving optimum yields of high quality fruit utilizing environmentally safe procedures. Priority is given to the utilization and enhancement of natural regulating processes and to the reduction of...
This is a two-part thesis. The first part is a generalization of vector calculus tools to Minkowski Space, a non-Euclidean 3-dimensional geometry that has a distance function that is not positive definite. We orient a cube in Minkowski Space using the generalized Stokes' Theorem to relate a divergence integral to...
Eco-certification of seafood has been suggested to be a key market based mechanism for reducing the pressure on the world’s aquatic ecosystems. In the study presented here we investigate to what extent consumers’ stated purchasing of eco-labelled seafood was correlated with seven internal variables: environmental knowledge, familiarity with eco-labels, subjective...
Five trellis types were compared during 1996 and 1997 for their effect on Pinot noir yield components, fruit composition, fruit set, shoot morphology, leaf gas exchange, and trunk carbohydrate storage. These trellis systems were: upright vertical, cane pruned (double Guyot); upright vertical, spur pruned (bilateral cordon); Scott Henry, cane pruned;...
Field and greenhouse experiments were conducted in 1996 and 1997 to evaluate the effects of integrating conservation tillage and cover cropping on broccoli production as well as agroecological parameters. A field experiment was conducted during 1996-97 at the Oregon State University Horticulture Research farm near Corvallis, OR. The specific objectives...
Most of the policy debate surrounding the actions needed to mitigate and adapt to anthropogenic climate change has been framed by observations of the past 150 years as well as climate and sea-level projections for the twenty-first century. The focus on this 250-year window, however, obscures some of the most...
