| 内容記述 | We attempted to clarify the effects of water table control by farm-oriented enhancement for aquatic system (FOEAS) and non-tillage cultivation on seeding efficiency, growth, yield, and seed component of soybean (Glycine max (L.) Merrill) grown on farmer’s fields in Tsukuba, Ibaraki. The experiment was performed for five years (2007- 2011) by using three cultivation methods: control field using conventional rotary seeding (CC), FOEAS field with conventional rotary seeding (FC), and FOEAS field with non-tillage narrow row cultivation (FN). The results showed that drainage improved in the FOEAS field, resulting in rapid lowering of soil moisture with higher soil bearing capacity after rainfall than that in the CC, and seeding efficiency was improved in the FOEAS field. Emergence was obviously higher and stabler in the FOEAS field than in the CC. Shoot dry weight at flowering was higher in the order of FN > FC > CC. The leaflet color (SPAD value) was darker and apparent photosynthetic rate was higher in plants grown in the FOEAS field. The shoot dry weight at maturity and seed yield were higher in the order of FN > FC > CC. Average seed yields of 5 years by FC and FN were 1.6 and 2 times higher, respectively, than that by CC. The high seed yield by FC was because of ripened pod number, and that by FN was because of ripened pod number and harvest index. It seems that yield increase by FC compared to CC was high in the year with large disturbances in water balance, such as severe drought, and excess moisture injury occurred. In addition, the dry weight of weeds was less in FOEAS fields. Further, green stem syndrome seemed to be lesser in the FOEAS fields than in the CC. No obvious effect of the cultivation methods was noted on the seed crude protein content. Our results suggest that FOEAS improves seeding efficiency, emergence, growth, and yield of soybeans, and non-tillage narrow row cultivation with FOEAS is suitable for Kanto region. |
