1.\u3000Controlling shade avoidance response as an avenue to increase potential crop yield<\/strong><\/p>\n\n\n\n

\u3000A lowered ratio of red and far-red irradiance (R:FR) is a warning signal for future competition, triggering plant morphogenic responses for shade avoidance, seen as increased apical dominance and reduced axillary bud growth. The growth and survival of tillers in wheat controlled by R:FR determines the final number of spike which is a major component of wheat yield. This study tests the hypothesis whether the reducing shade avoidance response increase the number of tiller in wheat or branch in soybean, and therefore increase yield potential.<\/p>\n<\/div>\n\n\n\n

\u3000Drip irrigation system, which has been developed for water-saving in arid land agriculture, is now applied to large-scale upland rice cultivation in some countries. In this study, drip rice cultivation in upland field is performed to estimate how much water could be saved compared to paddy, and to evaluate the emission reduction of methane: because paddy rice is one of the major source of methane emission in agriculture.<\/p>\n<\/div>\n\n\n\n

3.\u3000Ecophysiologicalapproaches to maximize potential yield of Japanese soybean<\/strong><\/p>\n\n\n\n

\u3000Japanese soybean yield (1.6 t\/ha) is only half of that in advanced cultivation country. This study aimed to optimize light interception and radiation use efficiency in soybean canopy using different cultivars or environment to improve cultivar and cultivation technologies, and to maximize potential yield of Japanese soybean.<\/p>\n<\/div>\n\n\n\n
