The writers studied on the relation between the harvesting time and the chemical composition of Renge. The summary of results obteined are as follows : (1) In this experiment, the flowers of Renge is begining to bloom at the end of April, and in full bloom at the middle of May. During this period, the very slight variation of water, crude fat, nitrogen-free extract and crude ash content were observed, but the decrease in crude protein and the increase in crude fiber observed in propotion to the growth. Moreover, the decrease and increase of both content were specially remarkable after stage of bloom (Figure 1). (2) The nutrient yield per tsubo (3.3 sq. m.) reached the maximum at the stage of full bloom, and afterward only the crude fiber increased (Figure 2). Its seems, therefore, that the best harvesting time is the stage of full bloom or immediately before.}, pages = {173--178}, title = {青刈飼料としてのレンゲに関する研究 : I. 刈取時期と成分の関係}, volume = {5}, year = {1953}, yomi = {コマツ, アキノリ and コスギ, キヨシ and クニマツ, ユタカ} }
