Looked at Rhizobium survival in the Palouse, particularly during the hot, dry months. R. leguminosarum had no problem surviving wide extremes of soil moisture, while soil flooding was detrimental to them. Rhizobium survival should be 10-15 years or more without a host plant. Dust storms did distribute Rhizobium, but not enough to insure uniform nodulation.

Tested 7 cultures of Rhizobium for nodulation and yield of Alaska seed peas. Also did a pot study with wheat straw and gypsum amendments. The field soil had never had peas before, but contained sufficient Rhizobium to inoculate peas. Seed inoculation tended to increase yields, but no culture was a sufficiently good N fixer to insure vigorous growth on soils low in available N. Soil amendments did not affect nodulation or growth. Yield differences were primarily due to variation in soil productivity.

Alfalfa seed treated with Phygon at 1.00, 0.50 and 0.25% dosages by weight of seed gave high significant germination as compared with nontreated seed. Arasan at 1.00 %, Dow 9B and 1.00 %, and Spergon and 0.50% dosage rates were all superior to nontreatment, but less effective than Phygon. Nodulation was not inhibited by chemical treatment of seed alfalfa, mungbean, yellow hop clover, Chinese red cowpea, hairy vetch, and Austrian winter pea, when chemical treatment was followed by seed inoculation with "Nitragin" bacterial inoculum. Nodulation of Chinese red cowpea was enhanced if seed of these legumes were treated with Phygon or Arasan and then inoculated with "Nitrigin". Chemically treated seed yielded more plants with nodules than nontreated seed. T: effect of seed treatments on alfalfa germination. Compatability of seed treatment and inoculation with nodule bacteria, and the effect on nodulation, in alfalfa and cowpea.
