| 内容記述 | We studied the yield response of soybean to the drip irrigation, in a heavy clayey upland field converted from rice paddy neighboring to paddy fields in Hokuriku Research Center for three years (2008-2010). We also estimated soil moisture in plow layer using modified tank model. Further, we conducted the deficit irrigation experiments using potted soybean in a greenhouse to verify the linear relationship between soybean yield and cumulative transpiration during the growing period. We tried to evaluate the risk of yield decrease by drought in soybean cultivated in heavy clayey upland field in Hokuriku region, based on the results of these experiments. The results are summarized as follows: 1) In the field experiment in which drip irrigation was applied after flowering so that the soil in plow layer was estimated to retain more than 25% of total available water, there was least need of irrigation and total amount of irrigation water during entire growing period was about 15 mm or less in each year of 2008 and 2009. On the other hand, in 2010 with higher temperature and less precipitation in summer, irrigation was often applied and 191 mm of water was irrigated in total. 2) Soybean yield did not increase with irrigation in the three years including 2010. Though LAI (Leaf Area Index) became larger and transpiration was stimulated by irrigation in 2010, the soybean with no irrigation did not suffer apparent water stress. 3) The modified tank model to estimate soil water in plow layer well represented observed data. 4) In the pot experiment, in which transpiration was limited by regulating water supply, linear relationship between grain yield of soybean and cumulative transpiration was observed. These results suggest that severe drought stress would not occur in soybean cultivation in heavy clayey upland field in this region and the increase of soybean yield by irrigation may be limited. | |||||||||||||||||||||||||||||||||||||||||
