Abstract
The emergence and survival of tillers and their contribution to yield of three varieties, Asakazekomugi, Norin 61 and Norin 64, were examined in four different soils to find the limiting factors to grain yield. Grain yield was the highest in Gray Lowland Soil (GLS) and lower in Red Soil (RS), Thick High-humic Andosol (THA) and Light-colored Andosol (LCA). Lower yields in the three soils were caused by a small number of spikes. In RS the emergence of Tc (coleoptile tiller), T1-T3 (tillers in the axils of first-third main atem leaves) and T1P (tiller in the axil of T1 prophyll) were the same as those in GLS, but the survival rates of these tillers were lower. The emergence and survival rates of TR (other tillers) were also lower than those in GLS. In THA and LCA the emergence rates of Tc, T1, T1P, and TR were lower than those in GLS. These rusults suggested the need of supplementary nitrogen application from January in RS and phosphoric-acid application before seeding in THA and LCA. Norin 64 had higher emergence and survival rates of T1 than the other two varieties, resulting in the higher yield in THA and LCA.
