Wild Blueberry Research Reports

The 1985 edition of the Blueberry Progress Reports was prepared for the Maine Blueberry Commission and the University of Maine Blueberry Advisory Committee by researchers with the Maine Agricultural Experiment Station and Maine Cooperative Extension Service at the University of Maine, Orono. Projects in this report include:

1. Control of secondary blueberry pest insects

2. Effect of pruning practices on blueberry insect abundance

3. Effect of hexazinone on species distribution in lowbush blueberry fields

4. Dichlobenil for control of bunchberry

5. Evaluation of postemergence herbicides for grass control

6. Hand-wiper applications of herbicides on woody weeds

7. Evaluation of steam …

The Effect Of A Bacteriophage On The Competition Of Rhizobium Japonicum Strains For Nodulation Of Glycine Max (L.) Merr, Lori Kelley

Masters Theses

The symbiotic relationship between Rhizobium japonicum (Kir.) Buch. and Glycine max (L.) Merr. was the concern of this thesis. This relationship occurs naturally in soybean fields. In the field there are many different strains of Rhizobium. Some of these strains fix atmospheric nitrogen more efficiently than others resulting in a higher crop yield. The problem is the more efficient nitrogen fixers are out-competed by less efficient nitrogen fixers. In order to solve this problem the more competitive strains have to be controlled. There are two main ways to do this. One is to increase the number of the desired …

Growth And Magnesium Uptake Of Tall Fescue Lines At High And Low Potassium Levels, J. H. Edwards, Jeffrey F. Pedersen

Department of Agronomy and Horticulture: Faculty Publications

Five tall fescue (Festuca arundinacea Schreb.) clonal lines with diverse root and xylem diameters were grown in nutrient solutions with magnesium (Mg) concentrations of 42, 125 and 250 µm and potassium K concentrations of 133 and 333 µm. Leaf Mg concentrations increased with increasing Mg rates at both low and high K concentrations. The tall fescue line with the largest root and xylem diameters had low leaf Mg concentrations, indicating a possible increased Mg tetany potential when consumed by cattle. The response of the K/(Mg+Ca) ratio in the plant, an indicator of tetany potential, to varying solution Mg at low …
