• 要約等: An experiment was carried on for several years at the Saitama Agricultural Experiment Station to ascertain the comparative effects of the rice bran, which is applied very widely in the vegetable culture in this country, lime of superphosphate and farmyard manure on the yield and quality of the sweet potato (Convalvulus Batatas L.) and Welsh onion (Allium fistirosum L.). The experimental plots were taken as follows (N=sulphate of ammonia, K_2O=sulphate of potash) : [table]The results obtained are summarized as follows : 1. As to the yield in the sweet potato, the plots were put in the order as (6)>(4)>(3)>(2)>(5)>(1), and positive effects of phosphoric acid and farmyard manure were clearly observed. 2. In Welsh onion the plots came in the order accordding to their yields as (6)>(2)>(4)>(5)>(3)>(1), and here also marked effects of phosphoric acid and farmyard manure were seen. 3. The result of chemical analysis of the sweet potato showed that, in the plot of lime of superphosphate with farmyard mamure starch was increased, while in the plots of rice bran, both with and without farmyard manure, crude fibre was increased. No appreciable relation could be observed between the sugar contents of harvests and the kinds of manure applied. The addition of farmyard manure showed a tendency to increase starch contents of harvests. 4. In Welsh onion, sugar was increased in the plots of lime of superphosphate, both with and without farmyard manure. The crude fibre contents were high in the plot of lime of superphosphate, as well as in that of rice bran with farmyard manure. As a rule, the application of lime of superphosphate was liable to increase sugar contents of harvests, and the addition of farmyard manure gave the same effect besides it tended to increase crude fibre contents. 5. It may be regarded that it is one of very beneficial systems of manuring in the vegetable culture to apply lime of superphosphate and farmyard manure instead of rice bran, because the formers are cheeper in cost and yet promise better harvests in yield and quality than the latter.
