“…Osvald's latent interest in allelopathy was rekindled through new discoveries concerning the potent effects of antibiotic substances, which were found to be effective at very low concentrations, fresh results from the United States, notably that concerning desert shrubs, and the work of Benedict (1941) who found the decaying roots of Agropyron repens to be inhibitory to the growth of brome grass (Bromus sp.). Ahlgren and Aamodt (1939) had also noted red clover (Trifolium pratense) and white clover (T. repens) rarely occurred in Agropyron sod, whereas alsike clover (T. hybridum) did.…”

“…Proebsting & Gilmore (1940) showed that neither exhaustion of plant nutrients or disease carried over from the last orchard could account for the failure of replanted peach orchards to make normal growth, but that peach roots added to virgin soil inhibited the growth of peach seedlings. Benedict (1941) showed that dried roots of bromegrass are inhibitory to bromegrass grown in sand cultures and suggested that an inhibitory substance in the roots may be responsible for the thinning of bromegrass stands after a few years. Bonner & Galston (1944) and Bonner (1946) found that water or nutrient solution in contact with roots of growing guayule plants accumulate substances which are toxic to the growth of guayule seedlings.…”

T,TST OF TABLES development (7 , 8, 9 , 16, 36, 38, 39 , 4,0) . Mclrieil and Davis (3l+) stud-iecÌ the effects of three levels of nitrogen fertility (0, J0 and 100 pounds of nitrogen per acre) on such characterj-stics as yield, culm number and protein contenü of nine spring wheat varieties" 1¡fith all wheab varieties the nunrber of cul_ms increased consistently with increased nitrogen fer'bility. Ceres wheat showed-the slightest increase i-n cu-hn number with respecti-ve increases of 7 "5 and 31"8 per cent for the J0-and lOO-pounds per acre rates of nitrogen application whj-l-e ï,ee wheat responded. most favorably to fertility treatment with correspond-ing increases in culm number of 46"ó and LO5.7 per cent for the same respective rates of nitrogen fertilization" Date of heading was advanced by f ro 4-days witir earl-j,esb matu.rity generall)r attained with tlre highest l-evel of fertiliiy.Bushel weight was not affected by the additional nitrogen" Although nitrogen fertiLization at both the 50-and. lOO-pounds per acre rates prod-r,rced su.bstantial increases in yield-and culm ntr¡rber of aLl-wheat variebies, neither rate of fertiliza.tion was apparently adequ-ate to increase proteirr content as well" Sarnples
