    Importance of vigorous germination in corn intended for seed has been emphasized for many years. More recently, within the present decade, not only vigor of germination has been emphasized but likewise the adverse effect of molds upon germinability has been freely asserted. One of the objects in beginning the present study was to get some information upon the question of whether the corn crop in such a new part of the corn belt as South Dakota was indeed affected by ear rots and root rots and similar organisms. A preliminary survey of a number of seed houses where seed corn was stored as early as the winter of 1923-1924 emphasized the fact that corn ear rots are a condition as well as a theory in South Dakota, even though they may be less prevalent than in older sections of the corn belt

    This bulletin states two general things: First, some elementary definitions of hybridity and the conditions of hybrid vigor; Second, at Brookings and Beresford it is possible that hybrid corn produced 2.8 bushels per acre higher than mass selected corn

    A Study of Sorghum with Reference to the Content of HCN

    Farmers and others concerned with the production and feeding of forage crops long have known that certain crop plants may be poisonous to animals. It also has been found that the poisonous property of certain plants consists of or is associated with prussic acid or hydrocyanic acid (HCN). The research reported in this bulletin are concerned with one principal forage crop, namely sorghum and its varieties

    The exploration of the unique properties of stored and cooled beams of highly-charged ions as provided by heavy-ion storage rings has opened novel and fascinating research opportunities in the realm of atomic and nuclear physics research. Since the late 1980s, pioneering work has been performed at the CRYRING at Stockholm (Abrahamsson et al. 1993) and at the Test Storage Ring (TSR) at Heidelberg (Baumann et al. 1988). For the heaviest ions in the highest charge-states, a real quantum jump was achieved in the early 1990s by the commissioning of the Experimental Storage Ring (ESR) at GSI Helmholtzzentrum fĂŒr Schwerionenforschung (GSI) in Darmstadt (Franzke 1987) where challenging experiments on the electron dynamics in the strong field regime as well as nuclear physics studies on exotic nuclei and at the borderline to atomic physics were performed. Meanwhile also at Lanzhou a heavy-ion storage ring has been taken in operation, exploiting the unique research opportunities in particular for medium-heavy ions and exotic nuclei (Xia et al. 2002)
