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 …

Rhizoctonia Patch Of Cereals, G C. Macnish
Journal of the Department of Agriculture, Western Australia, Series 4
Rhizoctonia patch is now widespread within Western Australia, having been recorded on all cereals and on a wide variety of other crops and pasture plants. Although the disease-as its name implies - looks spectacular in the field, the overall reduction in crop yield is probably small. However, its increasing frequency is causing considerable concern as the disease appears to be associated with minimum or reduced tillage systems.
