Sagebrush or other brush has first to be removed by the wheatland plow, by a 'brush rail, or by fire. One of the most successful methods of seeding is to drill right among the stumps on burned over sagebrush land. Other superior methods are drilling on soil plowed' early enough to settle or on land that has had the sagebrush railed off. Seeding in cheatgrass still remains a more or less unsolved problem. Disk ing off the cheatgrass before it seeds, or using some devise to permit seeding in a furrow with the right amount of. soil covering seems to hold the most, promise. Recent tests have shown that in open aspen stands seedings may be made before and during leaf fall without providing for covering with soil. It is accepted that newly seeded stands ought not to be grazed until after the forage grasses become established, which usually means no grazing during the first year, light grazing the second year, and thereafter grazing conservative enough to preserve the stand. Little is gained by a degree of overuse that abuses the stand and shortly makes another reseeding necessary. This is a management problem requiring careful study, just now begun. ... ... Normal and Abnormal Germination of Sugar Beet Seed Bion Tolman and Myron Stout U. S. Department ,of Agriculture, Salt Lake City, Uah A comparison of the germination of sheared sugar beet seed, whole seed balls, and naked seeds was made using blotters and soil in special glass germinators and also in the greenhouse bench. "These tests showed that most naked seeds and 12 to 15 per cent of the sheared seed germinated abnoramlly. This abnormal germina tion was evidenced by the fad that the cotyledons broke away from the starchy food reserve during the initial stages of germ ina tion and before the radicle had developed and become established. The cotyledons did not remain in a position to be pushed through the soil and there was also apparent some loss in geotropic response. As a result of these abnormalities very few seedlings from naked seeds and imperfect sheared seeds emerged from the soil when planted more than one half inch deep. It was evident that blotter germination tests gave an erroneous impression of the percentage of seed recovered on the shearing process, unless care was taken to differentiate between normal and abnormal germi ... ... ... ... nation.
