Outline of Final Research Achievements |
Sources of the variation of seed quality and yield of wheat and soybean in paddy-upland rotational fields were examined to evaluate the possibility of the variable rate management that implements the site-specific input of agricultural materials, e.g. fertilizer and seed, in proportion to the variation of these sources in the field for correcting the spatial variability of seed quality and yield. In the case of wheat, the variable seeding rate management in proportion to the soil moisture percentage on dried soil basis at seeding in the field was able to control the number of panicles in the field to bring the adequate average yield. In the case of soybean, the variable seeding rate management for controlling population density at seeding was able to control the stems structure of soybean to bring the adequate seed quality.It was shown clearly that the input-output balance was improvable without yield loss by correcting the spatial variability of wheat growth in a field.
