We carried out the experiment concerning the effect of Fe and Mn chelate compounds on the growth and yields of barley plant at both Tokorozawa dity in Saitama and Mobara city in Chiba prefecture. The metals stated above were supplied in water solution as such concentration as 10 p. p. m. to the 10 thousands kg. of surface soil per 1-tanbu, i. e. the concentration is 110 p. p. m. The seeding were practiced at October 31st, 1956 and the mature plants were harvested at June 1957. The results of experiment are as follows. 1) The growth habit of young plant was different between the Saitama characterized by lower temperature and the Chiba by higher temperature, i. e. the creeping habit at the former and the erect at the latter place. 2) At both places, however, it has been observed that the primary growth of barley in the treated plots were somewhat better than that of the control plots and the effect of the metals can be distinguished longer in the tillering than in the top hight. 3) And also the ratio of ear-bearing tillers to the total tillers was high in treated plot than control plots. 4) The yields of grains at the plots with the metals were increased at both places with significance at 95% level.
