We investigated the difference of work performance and crop yield in the two transplanted paddy fields applied minimum tillage (MT) and conventional tillage (CT). The obtained results were as follows.Although travel reduction of transplanter in CT was higher than that in MT, transplanting did not effect on qualities of rice seedling in both MT and CT. From the survey on plant growth, there were significant differences in plant length, number of tiller and value of SPAD (Index of chlorophyll content in leaf). Kind of weeds in MT was more than that in CT and quantity of weeds in MT was much than that in CT. There was no clear difference of grain yield between in MT nad in CT.From the measurement of soil penetrating resistance, monotonous change was observed in CT, but distinctive change was observed in MT with the lapse of time. There was no clear difference of three phases of soil between in MT and in CT except for some measured values. There was no difference of contents of nitrogen and carbon between in MT and in CT.The total required work time in MT was 70% less than that in CT. Finally the sampling numbers of hill required in a survey on grain yield for MT were decided.
