On the Cultivation of Grasses on the River-Sides : I Mainly about the comparison of adaptability of various kind pasture-grasses and the effects of fertilizing management

Abstract

The Abukuma- and the Naruse-river sides are picked up as the experimental grassland for the cultivation of the following kinds, namely; orchard grass, timothy, kentucky 31 fescue, red・clover and ladino・clover, with the purpose to get the comparison of adaptabilities of the grasses and effects of fertilizing management. The results of the study can be summarized as follows: 1. The yield of red・clover plot in richest for the first and second year, but its difference from the other grasses becomes less since the third year. 2. The growing condition of timothy is slower than those of kentucky 31 fescue and orchard grass, while the kentucky 31 fescue shows very strong registive force even at low degree of temperature. 3. It is red・clover plot among the experimental ones that weeds grow remarkably thick after the third year from seeding. The effect of fertilization to control the thick growth of weeds is not specially recognized. 4. The experimental plot is inundated with overflow of the river every year but there is observed scarecely its influence on the growth of grasses mentioned above.
