Abstract
In order to establish an environment-friendly agricultural production system, we developed a method to estimate the optimal area rate of a farm that applies block crop rotation, so that self-sufficiency of bio-diesel fuel could be achieved, using genetic algorithm. The method derives the area rate which obtains a high-profit produce by meeting 4 conditions which are the status in which continuous cropping may occur and draw on area rate of creating a profitable agricultural produce. The results of applying the developed method on a model farm in the region of Tokachi, showed that different area rates could achieve equivalent level of profit which indicated the efficiency of the developed method.
